About Me

My interests are in brain-machine interfaces (BMI). My research focuses on improving the accuracy and user-friendliness of cortical neuroprosthetic systems through machine learning and signal processing techniques.

 

I received my Bachelor of Science in Computer Science and Mathematics at Purdue University in 2004, and I received my Doctor of Philosophy in Computer Science from Duke University in 2010. My graduate advisor was Craig Henriquez.

 

I currently work in the lab of Miguel Nicolelis at Duke University.

Bio

 

I was born in Guangzhou, a large metropolis in southern China. I spent the first seven years of my life there. My family moved to Iowa City, Iowa and later to West Lafayette, Indiana. After I received a B.S. from Purdue University, I studied at Duke University and received my doctorate degree in 2010. I am now a post-doctoral associate at Duke. I am married; my wife, Chengting (Cassandra) Lai, graduated with a master’s degree from the University of South Carolina, where she studied international hospitality and tourism management. Our adorable baby girl, Kana Li, was born in 2011.
