Biosktech: Mary Ann Weitnauer (formerly Mary Ann Ingram) received the B.E.E. and Ph.D. degrees from the Georgia Institute of Technology (Georgia Tech) in 1983 and 1989, respectively. From 1983 to 1986, she was a Research Engineer with the Georgia Tech Research Institute in Atlanta, performing studies on radar electronic countermeasure (ECM) systems. In 1986, she became a graduate research assistant with the School of Electrical and Computer Engineering at Georgia Tech, where in 1989, she became a Faculty Member and is currently Professor.

Dr. Weinauer's early research areas were optical communications and radar systems. In 1997, she established the Smart Antenna Research Laboratory (SARL), which emphasizes the application of multiple antennas to wireless communication systems; this includes multiple-input-multiple-output (MIMO) architectures, smart antennas, and adaptive arrays. The SARL performs system analysis and design, channel measurement, and prototyping relating to a wide range of wireless applications, including wireless local area network (WLAN) and satellite communications, with focus on the lower layers of communication networks.
