I am a computer scientist who is curious about how human brain, eye, body, and cell, function. Hence I am always excited about developing robust image analysis methods and building autonomous and intelligent systems that integrate algorithms with efficient, application-specific designs to solve computational problems in biomedicine, perception, and cognition. In particular, I work toward robust medical imaging software based on computer vision and machine learning algorithms that aid medical doctors in accurate and reproducible diagnosis, and help them better understand the anatomical and physiological relationships in normal and diseased states. I develop image processing and analysis software for analyzing biological images to help biologists and biophysicists in understanding and modeling complex biological pathways and systems. I also create intelligent vision systems that are capable of learning effectively and reasoning about multiple sources of information in order to achieve functions typical of human vision.
