Background

I am currently a computer science and engineering Ph.D. candidate at the University of Michigan in Ann Arbor. Within the department, I work in the Advanced Computer Architecture Laboratory (ACAL) under my adviser Prof. Thomas Wenisch.

Research

My current research is in the development of hardware acceleration for mobile image processing and mobile computer vision. Because handheld devices have a strict power limit and because vision algorithms are so computationally complex, such a device is not within the capabilities of standard off-the-shelf hardware. Additionally different algorithms are necessary to support various types applications due to varying requirements in resolution, frame rate, image type, and error correction; therefore, the problem cannot simply be handled by a hard-wired algorithm. My research focuses on developing specialized hardware that makes use of knowledge of the various algorithms to provide high resolution images while staying within the power constraints. To date, my work has primarily been focused on accelerating 3D ultrasound for various applications from high resolution abdominal scanning to high speed 3D Doppler.

Personal

I grew up in a small town in Tennessee and later moved to Alabama, where my family currently resides. I also have one younger brother who is eleven years younger than me.

During my start of graduate school, I volunteered for over 3 years as a Big Brother in the local Big Brothers, Big Sisters program, and I am actively involved with outreach programs at the University of Michigan.

In my spare time, I enjoy origami and hobbyist boardgames for fun.
