Sean Hudson

Teaching Assistant (702700)

I am a graduate student in the Geography Department, working in the Ecohydrology Group, under the advisement of Dr. Delphis Levia. My research seeks to understand the complex system at work when precipitation falls over a forested area. I am specifically working on throughfall drop size distribution and drop generation, and its effect on nutrient and chemical cycling and soil moisture balance. 
Research Interests:
Throughfall generation, canopy interception, nutrient cycling, hotspots, hot moments, spatial variability of throughfall, temporal variability of throughfall, canopy-ground flow paths, Open-Source software and hardware in the Environmental Sciences.
Current and Ongoing Research:
Throughfall Drop Size Distribution measured by a laser disdrometer. Fair Hill NRMA, Maryland USA
Throughfall Exclusion and soil moisture recharge. Fair Hill NRMA, Maryland USA
