This is a volunteer position for the organization for all AAUP members in Texas. The AAUP is a nonprofit membership association of faculty and other academic professionals. Founded in 1915, AAUP has helped to shape American higher education by developing the standards and procedures that maintain education quality and academic freedom in this country’s colleges and universities. AAUP (representing faculty) jointly formulated with the American Association of Colleges and Universities (representing Presidents) the gold standard for academic freedom and tenure adopted by more than 1,000 colleges and universities and endorsed by more than 250 higher ed organizations. In August 2022, AAUP affiliated with the American Federation of Teachers (1.7M members including 148,000 professors).

As part of the 6G@UT Research Center and Wireless Networking Communication Group, we focus on signal processing and machine learning for 5G/6G physical layer communication systems to improve data throughput, reliability and coverage. We developed deep reinforcement learning algorithms for downlink cellular communications for (1) joint beamforming, power control and interference coordination; (2) multicell basestation coordination; and (3) switching between sub-6 GHz bands and millimeter wave bands. We also derived mixed analog/digital signal processing methods to improve communication performance in energy-efficient hybrid analog/digital beamforming architectures. On the 6G roadmap, we are also pursuing adaptive algorithms and reinforcement learning for reconfigurable intelligence surfaces and full duplex transmission. In these research efforts, we develop mathematical models, fast algorithms, system simulations, and prototype implementations. We develop algorithms with implementation constraints, and perform simulations and prototypes to quantify communication performance vs. run-time complexity tradeoffs to identify practical algorithms. We also conducted research in 3G/4G communication systems, Wi-Fi, and smart grid communication systems (2005-2018) as well as image/video processing (2005-2017). This previous research in communication systems included improving connection speeds for Wi-Fi, cellular and smart grid communication systems by mitigating interference and investigating large sensor arrays to improve cellular and underwater communications. The previous research in image/video processing included Improving visual quality when acquiring video on a smart phone by mitigating rolling shutter artifacts and assessing visual quality in computer graphics and high-dynamic range (HDR) images. For communication and image professing systems, we prototyped ideas in testbeds. We also developed design automation tools for distributed embedded systems.
