Signal Processing Research

I am a PhD student in the Digital Signal Processing and Computational Imaging labs at Rice University. My research focuses on the development, application, and analysis of new signal processing algorithms. I am especially interested algorithm design related to problems in computational imaging, machine learning, and communications. I work under the direction of professors Richard Baraniuk and Ashok Veeraraghavan.

Biography

I received my BSEE and MSEE from Rice University in 2013 and 2014, respectively. I am currently working towards my PhD in electrical and computer engineering, again from Rice. My graduate education has been supported by the NSF GRF, DoD NDSEG, and Texas Instruments fellowship programs.

I have had five summer internships; two at Ball Aerospace, one at ViaSat, one at National Instruments, and one at the Technical University of Braunschweig. In high school I worked weekends and summers as a construction laborer and apprentice electrician.

I am a social chair of the Rice ECE graduate student association and I am an active member of the IEEE. I regularly review for the IEEE Transactions on Signal Processing and the IEEE Transactions on Computational Imaging, in addition to smaller journals and conferences.
