Dr. Mary Ann Weitnauer (formerly Mary Ann Ingram) has been a member of the ECE faculty since completing her doctorate at Georgia Tech in 1989. Her research focus since the mid 1990s has been the application of multi-element arrays (MEAs) to wireless communications, with emphasis on multi-hop ad hoc, mesh, and sensor networks. She established the Smart Antenna Research Laboratory, which performs both experimental and theoretical studies. Lately, SARL has been developing and testing medium access control (MAC) and network layer solutions for multi-hop networks that have the ability to do cooperative transmission (CT) and distributed multi-input-multi-output (MIMO) at the physical layer. Synchronization for such distributed or virtual arrays is thus a current interest. The protocols are being demonstrated on a 40-node network of software defined radios (SDRs) in practical environments and topologies. SARL has developed Link Layer and Network Layer protocols that extend the life of multi-hop wireless sensor networks, including those that do energy harvesting. SARL also develops signal processing algorithms for impulse radio–ultrawideband (IR-UWB) radar for the purpose of non-contact vital signs measurement.
