About me

I am a Ph.D. student in Computer Science at Purdue University, advised by Dr. Ming Yin. My current research involves the areas of applied machine learning, crowdsourcing, and human-computer interaction. I designed and developed applications to 1) improve crowd workers' existing skills by peer learning, and 2) providing a more transparent environment for crowd workers.

Prior to Purdue, I worked in a technology company as an Android developer. I hold a Master of Computer Science from West Virginia University, and a Bachelor of Management in information Management from National Central University in Taiwan.
