General Information
I am currently a Senior Research Scientist at SenseTime. I finished my Ph.D from City University of Hong Kong in 2013. My research interests are: machine learning and deep learning with focus on deep convolutional neural networks, recurrent neural networks and their applications in computer vision, image processing, NLP and business. I am also interested in parallel computing on GPUs and Agile software development.
