UT Austin

I am a first second-year Ph.D. student in the electrical engineering program at the University of Texas at Austin. I am fortunate to be supervised by Prof. Jeff Andrews and to be part of his research group. I am also supervised by Prof. Sriram Vishwanath and part of his Laboratory of Informatics, Networks, and Communications (LINC). Along with many others, we are members of the Wireless Networking and Communications Group (WNCG).

In addition to being a graduate student, I am currently affiliated with GenXComm, a local startup that develops a suite of solutions that enable simultaneous transmission and reception in-band for various applications. GenXComm was founded in 2016 by Prof. Sriram Vishwanath and Hardik B. Jain.

I am fortunate to have recently been awarded the National Science Foundation’s Graduate Research Fellowship. I appreciate their support of my graduate research and of my academic pursuits!

I received my undergraduate electrical engineering degree from Missouri University of Science and Technology in May 2018. I was involved in undergraduate research supervised by Prof. Y. Rosa Zheng on the topic of underwater acoustic communication.

I have created and released MIMO for MATLAB (https://mimoformatlab.com/), a package for conveniently simulating and demonstrating multiple-input multiple-output (MIMO) communication. Its development and documentation are ongoing.

I am a licensed amateur radio operator. My callsign is KE0QVW.

Research

My graduate research aims to bring in-band full-duplex capability to millimeter-wave communication systems. This largely involves system-level analyses and the design of multiple-input multiple-output (MIMO) transmission and reception strategies. The goal of my research is to develop solutions that mitigate self-interference and enable reception while transmitting in-band.

Interests

My broad interests are in the theory and implementation of millimeter-wave communication, in-band full-duplex, and communication system optimization. Specifically, my interests and skills include PHY layer, MIMO, millimeter-wave, in-band full-duplex, optimization of MIMO communication systems, cellular systems, array signal processing, and communication system design and simulation. I enjoy learning new concepts and implementing them in MATLAB and Python.

My short-term goals are to build my knowledge of wireless and to develop myself as an independent researcher. While doing so, it is my goal to mentor undergraduate students and introduce them to signal processing for communication systems. My long-term goal is to have extensive theoretical background combined with an understanding of how concepts are implemented practically. Once I am finished with school, I want a career where I can research, develop, and prototype wireless technologies.
