The Engineering Education and Research Center (EER) at UT Austin

I am a first second third fourth-year Ph.D. student candidate 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 advised 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) and 6G@UT.

I am fortunate to have been selected as a National Science Foundation Graduate Research Fellow beginning in Fall 2020. I appreciate their support of my research and studies.

I have created and released MIMO for MATLAB (, a package for simulating multiple-input multiple-output (MIMO) communication. It is completely documented, and video tutorials are in progress.

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


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.


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, Python, and software-defined radio. My long-term goal is to have extensive theoretical background on wireless combined with an understanding of how concepts are implemented practically. Once I am finished with school, I look forward to a career where I can research, develop, and prototype wireless technologies.
