Research Interests

SEAL’s fundamental research motivation is to map and characterize global change, and to understand the consequences of these changes for the Earth system and society. Anthropogenic changes to vegetation (e.g. cropping systems, deforestation, etc.) are of particular interest. Example research questions include: How can we feed a growing population without running out of water? Have tropical deforestation mitigation policies been effective? How is vegetation phenology changing in response to a changing climate?

Modeling and Understanding using Temporal Analysis of Transient Earth Data (MUTATED)

Modeling and Understanding using Temporal Analysis of Transient Earth Data (MUTATED)

This project seeks to develop online methods of change detection across increasing large spatial and temporal scales.

Does chilling explain the divergent response of spring phenology to urban heat islands?

Does chilling explain the divergent response of spring phenology to urban heat islands?

This NASA-funded project aims to test the hypothesize that the divergent spring phenology trends in urban areas can be explained by the interaction between UHI-induced seasonal temperature changes and variable plant chilling requirements—the need of plants to be exposed to sufficiently low temperatures to release dormancy in spring.

Improving Near Real-Time Deforestation Monitoring with a Novel, Multi-Source Bayesian Method

Improving Near Real-Time Deforestation Monitoring with a Novel, Multi-Source Bayesian Method

This NASA-funded project aims to develop a novel method of aggregating multi-source satellite data while accounting for trade-offs in temporal latency and spatial accuracy. We also incorporate Bayesian updating with the goal of creating a daily deforestation probability map.

Climate Adaptive Agriculture in the EGP

Climate Adaptive Agriculture in the EGP

Meeting future food demand while coping with climate change will require substantial adaptation in smallholder systems. The principal motivation for this investigation is to determine the adaptive potential of smallholder agriculture in North India, Bangladesh, and Nepal, where smallholder communities experience large crop yield gaps, underdevelopment, and widespread poverty.
