Brief Bio

Andrew is currently a NASA Postdoctoral Program fellow at NASA Goddard Space Flight Center working with Ben Poulter in the Biospheric Sciences Laboratory and collaborating with Joanna Joiner, Randy Koster, and Abhishek Chatterjee. He is a hydrologist who studies how the soil-plant-atmosphere continuum exchanges water, carbon, and energy. Andrew's goal is to identify and understand soil and plant mechanisms that drive the land surface's response to variability and change. His current project at NASA involves investigating the effects of rainfall intermittency on the terrestrial biosphere using NASA satellites and modeling tools. He will be starting research on similar topics using ECOSTRESS in Spring 2023.

In April 2021, Andrew received his Ph.D. from MIT's Department of Civil and Environmental Engineering working with Professor Dara Entekhabi. At MIT, he used Earth-observing satellites to understand fundamentally how water moves through the soil-plant continuum following rainfall events at large spatial scales. Andrew studied these interactions using soil moisture and plant water content observations from NASA's Soil Moisture Active Passive (SMAP) satellite as well as using meteorological observations from the LandSAF SEVIRI satellite. A portion of his work included developing and improving algorithms for retrieving soil and plant water content from microwave satellite brightness temperature observations.

In 2016, Andrew graduated from Drexel University with B.S. and M.S. degrees in Civil Engineering. Working with Professor Franco Montalto, his master's thesis was on integrating green infrastructure into urban parks in NYC for stormwater management. Andrew was also a member of Drexel's Division I golf team.
