About Me

I am a Ph.D. candidate in the Computer Science Department at Duke University. I received my B.S. in Computer Science and Mathematics at Purdue University in 2004.

 

My interests are in brain-machine interfaces (BMI), artificial intelligence, and other topics that relate computer science and neuroscience. My research is about improving the accuracy and user-friendliness of cortical neural prosthetic systems through appropriate machine learning and signal processing techniques.

 

My advisor is Craig Henriquez and I work in the lab of Miguel Nicolelis.

Bio

 

I was born in Guangzhou, a very large metropolis in southern China. I spent the first 7 years of my life there. In 1990, my family moved to a little town called Iowa City, Iowa in the US. My father was pursuing a PhD in mathematics at the University of Iowa. In 1993, we moved to West Lafayette, Indiana, after my father decided psychology was more interesting and changed to a program at Purdue University. I spent the next decade in Indiana, completing my middle-school, high-school, and college education. With a B.S. from Purdue University in Computer Science, I came to pursue graduate studies at Duke in 2004. I am married; my wife Chengting (Cassandra) Lai is a Hotel, Restaurant, and Tourism Management student at the University of South Carolina.
