At the Earth Institute, she will be working with Prof. Maria Diuk-Wasser to develop simulation models to characterize the reciprocal interaction and feedback loops between human behavior and environmental risk of tick-borne diseases at multiple scales in northeastern U.S. within the conceptual framework of the dynamics of coupled natural and human systems (CNH). Her ultimate goal is to identify critical factors affecting disease transmission, which will aid in the design of improved intervention strategies to alleviate the biological and socio-economic burden of these diseases in affected communities.

Winslow Hansen (2018-2020 Cohort)

Winslow Hansen is a forest and ecosystem ecologist. His research seeks to understand whether forests will remain resilient to accelerating environmental change, where and why forest resilience may be eroded, and how novel forests will reorganize from the ashes of old systems. He is particularly interested in two areas: cross-scale interactions and feedbacks in forest ecosystems, including effects of forest change on continental-scale climate patterns, and how changing forest ecosystems can be sustainably managed. In much of his research, Winslow uses Alaskan boreal forest as his study system. Winslow earned his Ph.D. from the University of Wisconsin, Madison, where he used large-scale experiments, field observation, and computer simulation to identify the mechanisms underpinning postfire resilience of subalpine forests in Yellowstone National Park. He also holds degrees from the University of Alaska, Fairbanks (M.S.) and University of Montana (B.A.).

Sha Zhou (2018-2020 Cohort)

Sha Zhou received her Ph.D. in Hydraulic Engineering from Tsinghua University, China. She has broad research interests, including water resources management, carbon and water cycling, and atmosphere-biosphere interactions. Her Ph.D. dissertation focused on terrestrial water use efficiency and its application for evapotranspiration partitioning. She proposed a new partitioning method to separate plant transpiration from evaporation. This method could help determine the actual water requirement for both societal and natural ecological systems and reduce irrigation water loss via evaporation. Her proposed work in the Earth Institute aims to improve water productivity and resilience of the societal-ecological system in water catchments. She will develop a global database of actual water demand and a knowledge base for catchment management to underpin global sustainable water management.
