I am a research scientist / engineer in optical systems and signal processing. I was a postdoctoral researcher at the Biophotonics lab at Caltech in California from 2013 to 2018. During this period, I worked with a group of creative folks to develop advanced optical imaging techniques aiming to see deeper into the body. Prior to that I did my PhD study at the University of Nottingham in the UK where my research topic focused on ultrasound-modulated optical tomography. Prior to that I did my master and undergrad study at Beijing Institute of Technology. I have broad interest in creating and building things – novel methods, algorithms, systems, graphics, etc. If you are also interested in my work and want to talk more, I can be reached via my email address: firstnamelastname@gmail.com.
