Both Park and Hu are Ph.D. students in the Georgia Tech Electronics and Micro-System Lab, based in the School of Electrical and Computer Engineering (ECE). Their advisor is ECE Assistant Professor Hua Wang. 

Park is developing novel design methodologies and implementation techniques to realize ultra-compact and low-loss passive networks for RF and mm-wave circuits in a standard CMOS process. These passive networks include filters, quadrature hybrids, power combiners/splitters, and beam-forming networks for phased-array systems with concurrent multi-beam operations.

Hu is creating advanced wireless transmitter technologies by leveraging digitally intensive circuit architectures. Compared to conventional RF transmitter architectures, these digital transmitter architectures are particularly conducive to System-on-Chip integration in a highly scaled CMOS process (28nm and below) to realize low-cost energy-efficient mobile wireless data links. These circuit architectures achieve enhanced transmitter performance in back-off energy efficiency, linearity, bandwidth, and reliability.
