I am a postdoctoral research fellow in the Atmospheric Chemistry Modeling Group at Harvard University. My research is focused on understanding atmospheric composition in Africa. I make extensive use of space-based observations, primarily from the NASA Aura platform, and data from the global 3-D chemical transport model GEOS-Chem.

 

Research Interests:
Africa is poised for rapid population growth in the 21st century, but the economic trajectory is less certain. Previously I used observations of formaldehyde from the Ozone Monitoring Instrument to estimate isoprene emissions in Africa and compare these emissions to the widely implemented biogenic emission inventory MEGAN and limited isoprene flux measurements from field campaigns in Africa. I also identified a large enhancement in formaldehyde in Nigeria, where 1 in 5 Africans reside. There NMVOC emissions are higher per capita than China as a result of inefficient combustion and natural gas flaring/leakage. I am currently working on two projects: (1) obtaining a satellite-derived yield of isoprene secondary organic aerosols for Africa and the southeast United States; and (2) building a nested GEOS-Chem model over Africa to estimate the impact of ozone pollution on human health and crop yields.


Personal Interests/Hobbies:
Road running, building 2000+ piece jigsaw puzzles, piano, film appreciation.
