EDUCATION

Princeton University, Princeton, NJ, 1994-2000

Ph.D. Program in Atmospheric and Oceanic Sciences, January 2001

Thesis: Sources and sinks of atmospheric CO₂ estimated from batch least-squares

inversions of CO₂ concentration measurements. (J. L. Sarmiento, Advisor)

Johns Hopkins University, Whiting School of Engineering, Columbia, MD, 1989-1993

M.S. Applied Physics, May 1993.

PROFESSIONAL EXPERIENCE

Visiting Scientist, Climate and Global Dynamics Division, NCAR, Boulder, CO, 2003-present

Designed and implemented a 4-D Var data assimilation scheme to solve for sources and sinks of CO₂

at the resolution of a global transport model (2° x 2.5°). Also constructed the adjoint to the model.

Postdoctoral Fellow, Advanced Study Program, NCAR, Boulder, CO, 2000-2002

Researched the global carbon cycle, atmospheric tracer transport, state-space estimation theory,

observational network design, and variational data assimilation techniques.

Research Assistant, Atmospheric & Oceanic Sciences Program, Princeton Univ., Princeton, NJ, 1994-2000

Researched the seasonal and inter-annual variability of the global carbon cycle and the physical

processes controlling CO₂ sources and sinks; in the group of J. L. Sarmiento.

Aerospace Engineer and Cooperative Education Student, Attitude Analysis Section, Flight Dynamics

Division, NASA/Goddard Space Flight Center, Greenbelt, MD, 1985-94

Developed spacecraft attitude and orbit determination algorithms and software specifications for

several NASA/Goddard satellite missions. Supported the launch of several such missions. Also

managed contractor personnel to achieve these goals. Designed, developed, and tested a Kalman

filter for spinning spacecraft attitude determination. Learned state space estimation theory.
