Worked to sample and process deep sea core sediments from the Core Repository. Work largely focused on the Pacific Ocean, with occasionally work on Atlantic Ocean sediments.
Amanda Abrom is a master’s student at Columbia studying Economic and Political Development. She interns at the Center for Sustainable Urban Development where she works on the project, “Accelerating the SDGs” in order to raise awareness about the UN’s Sustainable Development Goals (SDGs). Before joining the Earth Institute, she taught English in Spain, as well as with the Chilean Ministry of Education in Chile. She also mentored youth leaders from 13 countries for the Middle Eastern Partnership Initiative and the SUSI Women’s Leadership Program for women from Sub-Saharan Africa. Currently, she serves as a Project Officer for the Global Schools Program, an initiative of the UN Sustainable Development Solutions Network (Youth) which raises awareness about the SDGs in school settings and promotes global citizenship education. She is a former Fulbright Scholar, White House Intern, and active UN Youth Delegate with the UN Conference on Trade and Development.
Project: Accelerating the SDGs
“The Local Project Challenge” is a research project to accelerate awareness about the United Nation’s Sustainable Development Goals (SDGs). Our team compiled data from 100 global development projects to see how the SDGs are being put into practice across education, the professions, and civil society. I co-planned the first UN Habitat Urban Thinker Campus at Columbia University School of International and Public Affairs (SIPA) and Graduate School of Architecture, Preservation, and Planning (GSAPP) in order to share the findings of the research team. The “Ideas for Action” document and the “UN Habitat Report” will detail the outcome of this summit. This project was showcased at the World Urban Forum in Abu Dhabi.
Amanda Weaver is a master’s student in public health studying epidemiology and concentrating in infectious disease epidemiology. After studying ecology and evolutionary biology at Rice University, she came to Columbia to build in a public component to her work. She spent the summer of 2019 researching the influence of climate on tick populations in Staten Island with the Diuk-Wasser lab. More broadly, she is interested in the anthropogenic effects of climate change, urbanization, and mass drug use on vector-borne diseases. After graduation, she hopes to continue to research infectious disease with the health department.
Project: Eco-Social Determinants of Human-Tick Interactions in Urban Landscapes
This project seeks to explore the coupled dynamics of ticks and humans in a close-contact urban environment. By taking advantage of Staten Island’s large park system, we were able to sample ticks in parks and yards, conduct knowledge surveys with residents, and trap small-mammals across the island. This work is increasingly important as tick-borne diseases are on the rise along the east coast and in urban environments. Not much is known about these dynamics in cities as much of the tick literature centers on more forested areas. This project aims to address this gap.
Anna Ledeczi is a junior studying Earth Science in Columbia College. She plans to attend graduate school to earn her PhD studying tectonics and geology after completing her undergraduate education. This project was begun under the Lamont Internship Program during summer 2019, and continued throughout the fall, ultimately resulting in a presentation at the American Geophysical Union.
Project: Seismic Evidence Supporting Plateau Origin of Northwestern Wyoming Lithosphere
My research explores the origin of the localized seismically fast region in Northeastern Wyoming, within the Wyoming Craton. Some have suggested this anomaly, which we have termed the “Wyoming Cratonic Anomaly” (WCA), is a relic of a chemically depleted oceanic plateau present on the Farallon Plate, which subducted under California around 90 Ma. We use body wave delays and their ratios to distinguish between the nearby thermal anomaly of the Yellowstone Hotspot and the chemically anomalous WCA.
Bailey is a senior at Columbia College studying Earth Science. Aside from pulling apart rocks, she enjoys playing the clarinet in the marching band and writing. After graduation, she intends to pursue a PhD in geochemistry and hike the Appalachian Trail, not necessarily in that order.
My research deals with the history of glacial erosion in Antarctica and the effects of past climate change on ice flow and land surface removal. By analyzing rock samples collected from the Transantarctic Mountains, I studied times when glaciers carved out the bedrock so extensively as to produce a buoyant response from the mantle, lifting more rocks up to take their place. I separated apatite crystals from 45 samples and thermochronologically dated them to understand when they were uplifted. I also participated in a two-week thermochronology workshop at the University of Arizona and presented my research at the American Geophysical Union (AGU).
Christy Dey is a senior at Barnard College double majoring in Economics and Environmental Science with an interest in Sustainability. She has spent her college career interning at a wealth management firm and held numerous club positions on campus such as President of the Pre-Veterinary Society, Treasurer of McAC, advisor at Matriculate and officer on the Honor Board. Outside of school, she has been doing karate for 13 years and is currently on the USA National Karate Team. She loves dogs, traveling and watching her favorite Netflix shows over dinner.
I have been interning at a wealth management firm throughout college and enjoyed this experience. I have never done academic research before, but being inspired by my thesis work and passionate about my topic, I quickly began to think more about research, academia, and career paths in this field. Last semester, I've done some PhD program experiences at universities such as Stanford University and really enjoyed hearing the opportunities available.

Project: The Psychology of Winter Park Use in NYC and Climate Change Perceptions
Literature is well versed in what elements of green urban spaces provide the most well-being to citizens. However, are these the same elements that are bringing people to the park in the first place? If we know that these spaces have such an important impact for mental health and well-being, how can the frequency of visits also be increased? Could it also be increased during the colder months and if so how? We will be conducting on-site ethnographic research at Washington Square Park in New York City to try to answer these pressing questions.
Daniela G. Santoyo is from Mexico and she is a second-year MPA student, concentrating in Energy and Environment at the School of International and Public Affairs (SIPA).

Project: Sustainable Cooling and Heat Adaptation in Dhaka, Bangladesh
In Dhaka, the capital and largest city in Bangladesh, rising average ambient temperatures coupled with the Urban Island Heat (UHI) effect threaten the city and its residents. The objectives of this project were twofold: (i) to understand the current coping strategies for heat adaptation used by residents in the Korail slum, and (ii) to assess whether cool roofs are an appropriate sustainable cooling solution for the community, to adapt and mitigate the negative impacts of heat. In March 2019, the research team travelled to Dhaka to conduct an ethnographic study and identify paths to implement our proposed solution.
Darren Rabinowitz is an MA candidate in the International Educational Development program at Teachers College, Columbia University. His research interests include education for sustainable development, peace building, and human rights education. As a 2019 AC4 Fellow, he studies the intersection of vulnerable Rwandan youth’s belonging and national peace building in the post conflict context. He currently works for the Teachers College Center for Sustainable Futures where he collaborates with the NYC Department of Education to investigate the efficacy of sustainability coordinators in NYC schools. In 2017, he worked as the informal education fellow at the Agahozo Shalom Youth Village in Rwanda.
This mixed methods research seeks to understand: 1) Rwandan orphaned and vulnerable children (OVC) self-reported feelings of belonging at an NGO-supported secondary boarding school and 2) how do feelings of belonging that are constructed within educational spaces relate to peace building in a post conflict country. Using McMillan et Chavis’ (1986) conceptualization of community, this research sheds light unto the specific nuances of Rwandan OVC belonging. I have presented the findings of this research at the 2019 Center for African Education Student Research Panel and at the 2020 CIES conference in Miami.

This research is part of a broader project hosted by the Columbia Center on Sustainable Investment (CCSI) to do transparency differently. In particular, this research is the first stage of an initiative to promote a demand-driven approach to transparency to stimulate more responsible investments. We analyzed the literature to identify what is the most important and useful information to disclose and why in the context of land-based investments. We first focused on host government perspectives to understand what their incentives and disincentives are to increase transparency. This work has positioned CCSI to delve more deeply into political economy analyses as a next step.
Dorothee is a junior in the School of General Studies majoring in Computer Science. Before continuing her education she worked in fashion for several years. She has always wanted to make a meaningful difference, so when beginning college she was sure she wanted to engage in research, though she was unclear of the field. After hearing about the opportunity through NASA SEDAC at Lamont Laboratory she knew this would be something that would interest her.
Project: Understanding Black Marble Data
This project was an exploratory research using the Suomi NPP Visible Infrared Imaging Radiometer Suite (VIIRS) nighttime light nightly data. While the environmental and economic uses of this satellite are understood and projected on NASA’s website, one of the goals of this research was to explore the social aspects this satellite’s images can identify. The basic method of this research was to find trends and patterns, along with exploring the potential of nightly data. The end goal is to have a higher frequency Population Density Estimation. I was able to present this research at AGU San-Francisco in December.

Project: Environmental Taxation in sub-Saharan Africa: Barriers and Policy Options
The paper provides an analysis of barriers faced by countries in sub-Saharan Africa in adopting environmental fiscal policy, and examples of their successful overcoming. Based on these considerations, it proposes an innovative blueprint to guide policymakers in introducing environmental taxation. The blueprint, aiming to fill a gap in specific policy guidance for these countries, is composed of 17 questions, to provide support in: (i) assessing the broader environmental, fiscal and socioeconomic framework for introducing environmental taxation; (ii) outlining policy priorities and intended outcomes; and (iii) identifying and overcoming constraints in administration, institutional capacity and political acceptance – key barriers detected in the analysis.
Elizabeth Perry received her MA in Climate and Society from Columbia in October of 2019 after completing this Earth Institute internship experience. Her research interests include climate and weather as well as their impacts in the built environment. She received her BA in Geosciences from Hamilton College in May 2018. She remains in the same research group at City College CUNY as a research assistant, synthesizing field data into a database. She intends to pursue a career related to climate and weather risks, computational geospatial data analysis, and insurance.
The Land-Ocean-Atmosphere Interactions group of City College CUNY uses satellite data and field observations to describe biogeochemical qualities of coastal and estuarine environments, including the Long Island Sound and coastal Alaska. As an Earth Institute intern during the summer of 2019, I gained data analysis and technical skills. I used a spectrofluorometer to assist characterizations of dissolved organic material of water samples collected throughout the Long Island Sound and the Yukon Delta. I also analyzed the spectral slope of dissolved organic material to compare satellite reflectance data with field observations. Finally, I participated in a field cruise in July 2019.
Emily Carrero-Mustelier is a junior undergraduate student of the School of General Studies of Columbia University currently majoring in Earth Sciences and with a deep interest in Geophysics. In 2019 she participated in the Lamont-Doherty Earth Observatory (LDEO) Summer Internship program and worked in the Seismology department under the mentorship of William Menke. As an intern, she investigated seismic anomalies in the Southeastern North American Asthenosphere by analyzing body-waves travel times from high qualities and successfully identified a major seismic slow velocity anomaly named South Coastal Anomaly (SCA). However, she is still working in LDEO to expand her investigation.
My research characterizes the seismic structure of the asthenosphere from Georgia to Virginia and develops evidence for the presence of low seismic velocities (and high temperatures) in that region. It is based on the analysis of high-quality maps of P and S wave differential travel time anomalies of several magnitude >6 teleseisms observed on the EarthScope Transport Array, along with forward modeling in a three-dimensional Earth model with simply-shaped heterogeneities. Consequently, one major seismic slow velocity anomaly, named South Coastal Anomaly (SCA), was identified and characterized as a 600 km long, 400 km wide, and 200 km deep thermal anomaly.
Emmerline is a chemistry major at the School of General Studies who is dedicated to saving the aquatic environment from plastic pollution through her research. She found that this was her calling after viewing many heartbreaking videos of dying or dead marine life entombed in plastic. As an eco-ambassador, Emmerline encourages her family and friends to be mindful of purchasing single use plastics. Based on her research, she also encourages them to purchase garments made of natural fibers such as cotton or wool, rather than synthetic fibers such as polyamides. In doing so, she hopes to aid in solving our plastic problem.
Project: Assessment of Synthetic Microfibers from Clothing in the Aquatic Environment and Implications for Zooplankton
Microplastics encompass all plastics that are less than 5mm. Microfibers are plastics that are shed from clothing made of synthetic textiles during the laundering process. It is estimated that 0.33 million tons of textile microfibers enter the oceans annually, via laundry. Thirty-three samples of various types of fabric were laundered, with and without detergent, in order to determine which fabric type sheds the most fibers. Fabric types included hemp, polyethylene, nylon, Tencel®, viscose, recycled polyester, polyester, and polyamide. Our results indicate that polyamide sheds the largest amount of fibers both with and without the use of detergent.
Eun Jin (Shelly) Son is a Columbia College junior studying Environmental Science. Her academic interests are hydrology, oceanography, and atmospheric chemistry. Her research interests are effects of anthropogenic activities and climate change on wetlands and global carbon storage, coral reef ecosystems, and public health. Currently, she is a research assistant at Lamont-Doherty Earth Observatory, studying marine sediments to understand the implications of climate change today on the Earth’s system.
In my project, I aim to reconstruct past variations in ocean circulation and climate using sediment records from Expedition 383, Site 1543, in the South Pacific. Marine Isotope Stage 11 is of particular interest as it is an interglacial period of warmer-than-present climate conditions in the Pleistocene. Preliminary results show that lighter-colored sediments, low magnetic susceptibility values, and high coarse fraction weight percentages are characteristic indicators of MIS 11. I will pick the planktonic foraminifera, G. bulloides, carbonate microfossils preserved in my study interval, and will analyze their stable isotope- and trace element- compositions to calculate the sea surface temperature.
Gabe is a junior at Columbia College studying Earth science. After taking introductory courses in Earth science, he became interested in Earth’s climate history. He currently participating in research of Earth’s climate during the last glacial period.
I picked T. quinqueloba tests from ocean cores and ran them through a mass spectrometer. The relative abundance of oxygen isotopes sheds light on past surface ocean temperatures and ocean salinity/ice volume. The time interval I am focusing on may better explain the variability of Earth’s climate during the transition period from the last glacial maximum to the holocene. I am specifically focusing on the T. quinqueloba because this species resides higher up in the water column than benthic foraminifera and should act as a better proxy for surface water temperatures.
A Missouri native, Grant is a senior in Columbia College majoring in Environmental Science. Post-graduation, he is pursuing environmental law after two years of deferral. During his deferral, he plans to work as an artist assistant to Zaria Forman, who documents climate change in her large-scale hyper-realistic pastel drawings of glacial ice. When he’s not busy getting stuck in marshes, he can most likely be found drawing, exploring downtown with friends, or sleeping. He is also involved on campus as a member of Shift and as the Resident Adviser for Greenborough and Potluck.
Coastal wetlands are perhaps the most efficient carbon-buying ecosystems in the world. However, they are increasingly at risk due to anthropogenic disturbance, sea level rise, and flooding induced by climate change. Utilizing National Wetland Inventory spatial area data and Dr. Peteet’s loss-on-ignition (LOI) carbon content and depth data collected from years of sediment coring and probing, this project creates preliminary estimates of full-depth total carbon stocks (kgC sequestered) for three lower Hudson marshes: Iona, Haverstraw, and Constitution. More LOI and probe data is necessary to validate these preliminary estimates.

Project: Drought and Air Quality: Satellite Data Analysis of Drought Impact on Ozone-precursor Emissions in North America
Air quality is influenced by both human-industrial behaviors and naturally occurring phenomena. One of the important natural phenomena controlling air quality is drought, which influences everything from microbial activity in soil to tree foliage emissions of isoprene. In order to understand how biogenic air pollution sources are influenced by climatological drought, I am using NASA’s Ozone Monitoring Instrument (OMI) to quantify differences in air quality between drought and “normal” conditions. The project aims to determine whether previously observed differences using ground instrument measurements can be detected by radiation spectrometers, such as OMI, aboard satellites.

Project: Sustainability Challenges in Coffee Production: Profitability and Adaptation to Climate Variability
Worldwide, 25 million smallholders and their families depend on coffee, which is affected by two challenges: low profitability and increasing climate variability and change. Current climate and economic analyses are entirely disarticulated from the farm level, limiting the opportunity to identify and generate feasible strategies that reduce vulnerability and increase resilience. The project aimed to determine and quantify how specific climate events affect the cost structure at the coffee farm level and to, in a second phase, generate an innovative and dynamic tool that integrates climate services and cost of production estimations based on characteristics and production practices at each farm.
Mengbi Chen is currently an MPA candidate in Environmental Science and Policy at Columbia University’s School of International and Public Affairs.

With strong interests in environmental issues and policy, she has worked on several research projects ranging from PM 2.5 to China’s BRI both as an undergrad and graduate student.
This study investigates carbon storage capacity of Piermont Marsh and compares it to our carbon footprint. By analyzing a sediment core taken at Piermont Marsh, we were able to determine its carbon content at each depth layer to estimate the total carbon storage of Piermont to be roughly 353,000 tons. It is equivalent to annual emissions of 280,000 vehicles, or 217,000 NYC residents, or 3% of annual NYC emissions. Therefore, it is important that we preserve tidal marshes given their huge carbon storage potential as global greenhouse gas emissions increase by year.

Roger Creel is a geophysics PhD student at Columbia University and the Lamont-Doherty Earth Observatory. In his research, Roger studies sea level change during past glacial cycles to improve our understanding of how ice sheets respond to warming. He focuses on sea level during the Holocene (11,000 year ago to present) and the Eemian (128-119 thousand years ago) interglacials. Before matriculating at Columbia, Roger danced professionally with the Louisville Ballet, where he created and grew a partnership with Kentucky’s largest Shakespeare company that gives lower-income students opportunities to perform as equals with professional ballet dancers. To date, their free performances have reached more than 23,000 people, many of whom had never seen dance. Roger believes in the power of community outreach, and is actively involved in climate advocacy at Columbia. He also serves on the advisory board for Read Ahead, a New York-based mentoring non-profit.
We reconstructed sea level during the Last Interglacial (~125,000 years ago), a geologic time period whose similarities to the modern Earth—shrinking ice sheets, warm temperatures, rising seas—make it a crucial reference point for simulations of future climate. To determine paleo sea level, we made precise elevation measurements of sea level indicators preserved on two Bahamian islands, Long Island and Crooked Island. We corrected our survey elevations for post-depositional effects, such as glacial isostatic adjustment (GIA), which displace local sea-level data relative to the global mean. Our research has already produced a publication (Dyer et al., 2020).
Sam Kodama is a senior in the Department of Earth and Environmental Sciences. He has been working in labs at Lamont since sophomore year and has enjoyed his time there.
Project: Investigating the Erosional History of Wilkes Subglacial Basin with Low Temperature Thermochronometry
This project aims to discover the evolution of the subglacial topography of Wilkes Subglacial Basin. Understanding the subglacial topography and how it has changed over time can provide constraints for ice sheet models. We studied the past subglacial topography with (U-Th)/He dating of ice rafted pebbles cored by the Integrated Ocean Drilling Program. Pebbles showed major glacial erosion occurring during the Middle Miocene and Early Pliocene.
Serena Tohme is a first year dual degree student between the School of International and Public Affairs (SIPA) and the Mailman School of Public Health. At SIPA, she is completing a Master of Public Administration in Economic and Political Development, where she is specializing in International Conflict Resolution and the Middle East. At Mailman, she will earn a Master of Public Health in Population and Family Health, with a focus on health in forced migration. She is Lebanese-American and she holds a BA in Psychology from Rice University in Texas. She has worked in the humanitarian space in Lebanon, Greece, and the United States involved in issues of healthcare provision in forced migration contexts, with a special emphasis on mental health and psychosocial support for children and families.
The research aims to investigate the design, implementation, and monitoring of child psychosocial programming (PSS) in informal education spaces on the Greek island of Lesvos, where over 20,000 refugees from Syria, Afghanistan, Iraq, and other countries are held awaiting asylum claims. PSS programming is critical in this context as it is a necessary element for children to process trauma and violence they have experienced on their journey to Greece, as well as continue any education that has been interrupted. The inclusion of PSS programming in Education in Emergencies (EiE) spaces is an increasingly important research topic in this field.
Tejaswini’s interest in waste management stemmed from her relocation to India in 2011, where garbage has been ubiquitous for decades. In the city of Bangalore, she voluntarily conducted comprehensive research to understand the functioning of the waste system, including economic, social, and political challenges. Tejaswini feels fortunate to have had the opportunity to gain exposure to the commonalities and incongruities in waste systems across continents, which equips her with the understanding of waste management systems in emerging markets and developed countries. While she does not discount the significance of behavioral change, she strongly believes in the power of innovation and capital markets to bring about systemic change. Tejaswini views waste as a resource, and is currently working towards the deployment of state-of-the-art technologies to increase transparency and accountability in existing global waste supply chains. Tejaswini is currently pursuing a Master’s in Sustainability Management at Columbia University.
Project: Enabling Waste Tracking and Data Transparency to Accelerate a Circular Economy
Waste generation has increased exponentially over the years. This is economically and environmentally unsustainable. A core and typical issue in the waste management systems today is the lack of visibility and accountability in the waste value chain. If there existed an infrastructure to track and monitor the flow of waste from generation to disposal, how would it affect the key stakeholders in the waste management—financially and socially—and how willing would they be to participate in the new system? Through the project, I would like to engage with stakeholders and find answers to these questions.
