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


Research Interests:
Africa is poised for rapid economic and population growth in the 21st century. I have 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 resides. We estimate NMVOC emissions in Nigeria that are higher per capita than China from inefficient combustion and natural gas flaring/leakage in the Delta. I am currently working on obtaining a satellite-derived yield of isoprene secondary organic aerosols for Africa and the southeast United States.

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