My research interests lie in the broad fields of signal processing, communications, and control. Together with my students and collaborators, we use insights from these fields, and the fields of optimization and information theory, to gain fresh perspectives on the fundamental principles that underlie emerging applications, and to develop algorithms that can put the resulting understanding into practice. One of the signatures our work is the development of computationally-efficient design techniques that explicitly incorporate the uncertainties in our knowledge of the system that is to be optimized. Some of our current areas of interest are: integrated sensing and communication (ISAC) systems, the computational offloading problems that arise in mobile edge computing (MEC), user-centric and cell-free large-scale multiple-antenna communication systems (“massive MIMO”), and the characterization of radar targets from resonant responses.

3 unit(s) T. Davidson (cross-listed as CSE 710) Concentrates on recognizing and solving convex optimization problems that arise in engineering. Convex sets, functions, and optimization problems. Basics of convex analysis. Least-squares, linear and quadratic programs, semi-definite programming, minimax, extremal volume, and other problems. Localization methods. Optimality conditions, duality theory, theorems of alternative, and applications. Interior-point methods. Applications to signal processing, control, circuit design, computational geometry, statistics, and mechanical engineering. The prerequisites are – a good knowledge of linear algebra and willingness to program in Matlab; exposure to numerical computing, optimization, and application fields helpful but not required; the engineering applications will be kept basic and simple.
