Hi, my name is Chan. I am an Insight AI fellow, working on various deep learning projects.
I have always been intrigued by challenging research topics that require scientific methods, mathematical ideas, and computational analyses. I have a wide range of background and interest from string theory to kernel programming and feel comfortable with communicating both in mathematics and in source codes.
I have both professional and academic research experiences, please see my Resume and CV.
From 2003 to 2005, I had worked as a system programmer on various projects, including building a query recommendation system for a web search engine and developing an operating system for an atomic force microscope electronic controller system.
During my graduate study at Caltech and postdoctoral research at Rutgers, I have worked on topics at the intersection of physics, mathematics, and computational science. Throughout my research career I have written several papers and have given talks at various places about the study of quantum field theories and their non-perturbative aspects via string theory, as well as have developed a couple of python programs (loom, cproj) with web interface, about which I gave a talk at SciPy 2016 conference.
