My research group is based on solving theoretical and applied problems arising in Wireless Communications and Signal Processing. Of particular interest are optimization methodologies that iteratively refine siganl quality and engage performance insights to understand the fundamental limits. There are numerous applications of my research in statistical inference, adaptive signal processing, information theory, spectrum intelligence, machine learning, and data science.

I received my Ph.D. degree from Purdue University in Electrical and Computer Engineering. Prior to joining the University of Kansas (KU), I was a postdoctoral researcher at KTH and an assistant professor at City University of Hong Kong, where I received President's Award. I was a recipietnt of the IEEE Communication Society Stephen O. Rice Prize in the Field of Communications Theory. I received KU School of Engineering Miller Faculty Scholar Award.

I am also active in filing intellectural properties based on 5G-&-beyond Broadband standard research. I have over 29 granted US patents. One of my invension has been implemented as a standard Transmit Precoding Codebook in WiMAX. I am also interested in over-the-air experiments using software-defiend ratio (SDR) platforms.

Postdocs: One postdoc position focused on Wireless Communications and Signal Processing (spectrum sensing, data fusion, and machine learning) is available. If you are interested, please send me your CV or apply to here.

For prospective graduate students: I am always looking for highly motivated students who want to conduct research in my group. If you fit the description, please feel free to send me an email that contains as minimum support (i) your CV and (ii) a review of one of my papers. I read all emails but have difficulty in responding to every email.
