About Me

I am currently a 5th year Ph.D. student at the University of Michigan. I received my B.S. in Computer Science (summa cum laude) from the University of Texas at Dallas in May 2012 and M.S. in Computer Science from the University of Michigan in May 2014. I currently work with Professor Emily Mower Provost, specializing in speech recognition, computational paralinguistics, and speech-based assisitve technology for individuals with aphasia.

Before joining Michigan, I worked on speech emotion recognition in Professor Yang Liu's lab as an undergraduate research assistant. I interned at Amazon (Seattle, WA) as a software engineer in Summer 2011 and 2012, where I worked on automated UI testing with Ruby on Rails and helped develop the mobile authorization platform for Kindle devices.

In Summer 2015, I interned with Facebook's Language Technology Group (Menlo Park, CA), now a part of Applied Machine Learning, focusing on Deep Neural Network acoustic model adaptation for large-vocabulary speech recognition. I came back to Facebook in Summer 2016 for a return internship, working on end-to-end speech recognition and acoustic model compression.

**UPDATE** I graduated in August 2017 and currently work at Facebook as a Research Scientist.


I have always been fascinated by the human mind and its relation to the computer's artificial brain. Broadly speaking, I am interested in using the computer's modeling power to better understand the inner workings of the human mind, and using this understanding to create more intelligent software programs. The aspect that I am most interested in is human speech, which not only encodes semantic content but also influences the perception of other people about the speaker, such as his/her emotion, competence, personality, eloquence, etc... I am interested in developing computational methods to model this kind of subjective perception. My current research interests include: machine learning in speech/language processing, computational paralinguistics, emotion recognition, speech-based assistive technology, and clinical applications.
