Quantification of the effects of human activity on
the composition of Earth’s atmosphere by the development of computer
models used to analyze a wide variety of observations. Focus on
climate change, stratospheric ozone depletion
and recovery, air quality, and the global carbon cycle. Participant in
numerous atmospheric chemistry field campaigns and
Earth Observing Satellite missions, including
the Convective Transport of Active Species in the Tropics (CONTRAST)
field campaign conducted in Guam during Jan and Feb 2014, and the
FLAGG-MD effort to quantify the fluxes of
atmospheric greenhouse gases in Maryland and nearby regions.

truly, with community members and activists at a meeting entitled "Think
Globally/ Act Locally"
April 2017, Church of the Brethren, University Park, Maryland. About 100
people attended this
ranging, ~2 hour long discussion sponsored by the Prince George's
Country Resist Coalition.
supervising the research of 7 graduate students and 2 faculty
research assistants at UMD who are working on a wide range of
research topics related to atmospheric chemistry and climate. In the
past have had close collaboration with a dozen graduate students at
Caltech, University of Colorado, and Harvard as well as supervision
of research studies of 5 postdoctoral fellows.
A little fun
for those who have scrolled so far.
I have benefited from many great
instructors at Cornell and Harvard, as well as
Fallstaff Elementary (especially Ms. Wood, who emphasized that
hard work was the most important ingredient for success) and Pimlico Junior High
School (especially Mr. Moody, my first teacher to instruct that it
was important to question authority). My future was shaped by the
outstanding education at
Institute (BPI) a premier public high school (especially Mr. Gneiting
Sanford, who taught me how to appreciate science at a deep level
including self-education, and Ms. Strickland, who taught chemistry
as an elegant science). At the time I attended, BPI was in the midst
of a most remarkable transformation. My senior
class had N
men, and 1 woman, because a courageous young lady who had graduated the year
before threatened a lawsuit if she could not attend. As a
result, there was also 1 woman in my graduating class.
Below is a picture of my home room
class, Ae1, senior year, taken on the day of our Boiler
Project presentations. My group described the results of our
rendition of the Millikan Oil Drop experiment, which we conducted
with the help of a Professor of Physics at nearby
University. I'll be impressed if you can identify me
in this photo.

high school. User beware!
