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 and computer 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 startup that develops a suite of full-duplex 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.

Ph.D. Research

My Ph.D. research aims to bring in-band full-duplex capability to millimeter wave communication systems by leveraging dense antenna arrays to mitigate self-interference in the spatial domain. I combine theory, measurements, and practical knowledge to motivate, develop, and validate my research in an effort to create full-duplex solutions that integrate into real millimeter wave communication systems.


My broad research interests are in millimeter wave communication; in-band full-duplex; MIMO; communication system design, optimization, and simulation; interference cancellation; array signal processing; radar; and satellite communication systems. My 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.
