Lalitha Sankar is an Assistant Professor in the School of Electrical, Computer, and Energy Engineering at Arizona State University. She joined in Fall 2013. Prior to that she was a Research Scholar in the Department of Electrical Engineering at Princeton University working with H. Vincent Poor. She was also a Science and Technology Teaching and Research Fellow supported by the Council on Science and Technology at Princeton University.
She graduated with a Ph.D from Rutgers University, where she worked with Narayan Mandayam while collaborating with Gerhard Kramer (then at Bell Labs). Prior to that, Sankar was a Senior Member of Technical Staff at AT&T Shannon Labs, Florham Park, NJ, where she worked on design, development and prototyping of next-generation wired and wireless systems such as multi-band software radios and DSL modems. This was preceded by a year developing signal processing algorithms for the first digital camera prototype developed at Polaroid Corporation Engineering R&D in Cambridge, MA. Lalitha has a master’s degree from the Department of Electrical Engineering at the University of Maryland, Baltimore County and a bachelor’s degree in engineering physics is from the Indian Institute of Technology, Bombay, India.
Lalitha Sankar received the best paper award from the IEEE Globecom 2011 for her paper on side-information privacy with R. Tandon and H. V. Poor. For her doctoral work, she received the 2007-2008 Electrical Engineering Academic Achievement Award from Rutgers University.

In large wireless networks, heterogeneous users with competing interests may not cooperate to share their resources without incentives. Using information rate as the incentive for every link in a network of multiple interfering links, we use coalitional game theory to...
While cooperation can increase diversity in wireless networks, the tradeoff at every node of using resources for self vs. cooperative transmissions can make dedicated relays desirable. In my doctoral work, I compare the diversity gains achieved by inter-user...
The capacity region of multi-terminal networks remains a long-standing open problem, with the exception of a few classes of networks. With increasing demand for wireless data networks, developing fundamental performance limits is both essential and imperative to...
In contrast to and in addition to the traditional link layer cryptographic schemes, a relay can exploit the noisy physical channel to assist in ensuring the secrecy of data packets from untrusted eavesdropping nodes. In , we develop optimal source and relay...
Wireless networks are characterized by two distinct features: fading and interference. Signal designs for wireless networks need to be optimized for channel variations for efficient allocation of radio resources. I develop optimal signal designs and scheduling...
Information technology and electronic communications have been rapidly applied to every sphere of human activity, including commerce, medicine and social networking. The concomitant emergence of myriad large centralized searchable data repositories has made...
One of the hallmarks of the smart grid is a vastly expanded information collection and monitoring system using sensing, communication, and control technologies including GPS-synchronized phasor measurement units (PMUs) in the high voltage transmission networks and...
