Profile

Gail L. Rosen received her B.S. with highest honors (1999), M.S. (2002), and Ph.D. (2006) in Electrical and Computer Engineering all from the Georgia Institute of Technology in Atlanta, GA. She joined Drexel University in the Fall of 2006 as an Assistant Professor.

Her research interests are in the areas of signal processing for biological applications: (a) bio-inspired algorithms for chemical localization systems used for finding explosive and illegal substances and (b) analysis of coding structure and tandem repeats in DNA sequences. The work illustrates how signal processing is a tool to reverse engineer biological systems, and how a better understanding of biology can improve engineering designs.

Her current research investigates the way a single-cell mobilizes in response to a chemical gradient, known as chemotaxis. She shows how inspiration from receptor clustering in chemotaxis improves gradient-source (chemical/thermal) localization in diffusive environments. Also, she has shown that using a sensor cross-correlation method, similar to binaural hearing, can be used to solve chemical localization in difficult turbulent scenarios and is interested in sensor network and fusion techniques to solve turbulent chemical source localization.

She is also interested in engineering education at the K-12 level. In 2003-2004, she was a NSF GK-12 Fellow and augmented mathematics and science classes in an urban Atlanta high school. Her major contribution was designing and instructing bi-weekly trigonometry and precalculus Matlab computer-based lesson plans to reinforce classroom concepts.

In her graduate studies, she was a recipient of a NSF Graduate Research Fellowship, NSF GK-12 Teaching Fellowship, and an AT&T Research Laboratories grant. She has received numerous awards such as a 2003 Georgia Tech ECE Outstanding Teaching award, a 2005 Georgia Tech Outstanding Research Paper award, 2nd place in the best student paper competition in the 2004 IEEE Sensors Conference, and a Best Student Paper award in the 2006 IEEE Conference on Acoustics Speech and Signal Processing (ICASSP) conference. She was also selected to attend the AdvanceVT Transforming the Professorate conference in July 2006, promoting and preparing women for careers in science & engineering. She is a member of IEEE, the IEEE Engineering in Medicine and Biology Society, and the Society of Women Engineers. She is a reviewer for IEEE Transactions on Biomedical Engineering and IEEE Engineering in Medicine and Biology Magazine.

She also has professional experience in several areas. In 1997-98, she worked full-time at Scientific-Atlanta, designing a digital cable box boot process and testing the overall digital video system. She has intern experience with AT&T Research Laboratories in 2000 enhancing surround-sound playback and with MIT Lincoln Labs in 2004 detecting particle events in an HVAC system.
