Bio
My research and teaching interests are to make cellular communication systems faster and more reliable, and improve visual quality when taking and displaying pictures and video. For my research, I was elevated to IEEE Fellow in 2009 (news release) and received several best/top paper awards. For my teaching, I received a Texas Exes Teaching Award and several other teaching awards. I currently hold the Engineering Foundation Professorship.

Our group is researching multiantenna systems to improve 5G/6G cellular communications over millimeter wave bands. We're investigating mixed analog/digital signal processing basestation architectures to reduce power consumption by 10-100x, and developing algorithms to maximize their communication performance. We're also investigating machine learning to improve 4G/5G handover, 5G basestation coordination, and 5G network fault remediation.
