Dr. Amy Braverman

Dr. Amy Braverman is a statistician specializing in statistical methods for analysis and uncertainty quantification in remote sensing. After graduating from Swarthmore College in 1982 with a B.A. in Economics, Dr. Braverman worked for nearly a decade in litigation support consulting. She returned to graduate school at UCLA in the early 1990's where she earned an M.A. in Mathematics and Ph.D. in Statistics. In 1999 she began a post-doc at JPL, and has been with the Lab ever since. Dr. Braverman's early work was in the use of data compression methods for analysis of massive data sets. As her career advanced, she has worked in spatial and spatio-temporal statistics, data fusion, statistical methods for the evaluation of climate models, and most recently in Uncertainty Quantification. She has been at the forefront of JPL's efforts to bring rigorous UQ to the derivation of geophysical information from remote sensing observations collected by NASA and JPL instruments. Dr. Braverman finds special satisfaction in mentoring post-docs and young researchers to build capability in Statistics and UQ at JPL, and in collaborating with academic colleagues to connect their research to JPL and NASA problems.
