Biography:

Sanjay Raman received his bachelor's degree in EE (with Highest Honor) from Georgia Tech in 1987. From 1987-1992 he served as a nuclear trained submarine officer with the U.S. Navy. Following his tour of duty with the Navy, he returned to graduate school at the University of Michigan and received the master's degree in EE in 1993. He completed his Ph.D. in Electrical Engineering at the University of Michigan in 1998 in the area of novel millimeter-wave integrated antennas and electronics. Dr. Raman joined the faculty of the Bradley Department of Electrical and Computer Engineering at Virginia Tech in January 1998 as an Assistant Professor, and he was promoted to Associate Professor in 2003. He established the Wireless Microsystems Laboratory at Virginia Tech to explore enabling ideas and technologies for integrated microsystems -- in particular microsystems that are connected to the information infrastructure via wireless communications links. He is currently serving a three-year term as an Associate Editor for IEEE Transactions on Microwave Theory and Techniques. He also currently serves on the technical program committees of the IEEE Radio Frequency Integrated Circuits Symposium and the IEEE Radio and Wireless Symposium. Dr. Raman's academic honors include: 2000 Presidential Early Career Award for Scientists and Engineers (PECASE) (1999 NSF CAREER Award); 1st Place, Student Paper Competition, 1996 IEEE MTT-S International Microwave Symposium; 1996-97 Armed Forces Communications and Electronics Association (AFCEA) Postgraduate Fellowship; and 1st Place, Student Paper Competition, 1995 IEEE Antennas and Propagation International Symposium.
