I am a PhD student in the Machine Learning, 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 in algorithm design related to problems in computational imaging, machine learning, and communications. I work under the direction of professors Richard Baraniuk and Ashok Veeraraghavan.

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 six summer internships; one at the Naval Research Laboratory, 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 projessional development 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, Image Processing, and Computational Imaging, in addition to several other journals and conferences.

My office is room 1033 in Duncan Hall.
