Title: Biologically-Inspired Gradient Source Localization

Abstract:
Currently, animals are our detectors and trackers of chemical sources such as explosive vapors and illegal substances, but they are expensive to train; therefore, electronic implementations are needed. In our research, we examine the way a single-celled organism mobilizes in response to chemical gradient, known as chemotaxis, and use its receptor clustering mechanism to improve gradient source localization. Then, the localizer is implemented, and the performance is evaluated.

Bio:
Gail Rosen received both a B.S. (highest honors) and M.S. in electrical engineering from the Georgia Institute of Technology, in 1999 and 2002, respectively. Since 2002, she continues at the Georgia Tech Center for Signal and Imaging Processing (CSIP) to pursue a Ph.D. in electrical engineering.

She interned in MIT Lincoln Labs biodefense department in the summer of 2004 and studied how to detect unusual aerosol particle events in HVAC systems. Her main research interests are reverse-engineering biological systems and analyzing DNA structure, mutations, and repair.

The gradient source localization work she will be presenting received 2nd place in the 2004 IEEE Sensors conference's best student paper contest.
