Associate Professor
Biostatistics and Medical Informatics Department & Electrical and Computer Engineering Department
I perform multidisciplinary research in applied computational optics and imaging. Optical imaging traditionally has been focused on producing and processing human interpretable images. This approach is becoming impractical on the collection side, where virtually infinite amounts of optical data can be collected, and on the processing side, where computers rather than humans are used to interpret images. My research focuses on developing new ultrafast computational optics and imaging methods that, by co-designing collection hardware and processing software, extend human and machine vision both quantitatively – improving image parameters soch as resolution – and qualitatively – developing new kinds of capabilities that are beyond what even the best possible traditional image could deliver. I am developing ultrafast computational cameras that can see around corners, through scattering media, and can detect cancerous tissue and evaluate plant health by detecting fluorescence lifetime.
Besides my academic work, I am co-founder of two companies: OnLume develops surgical fluorescence imaging cameras, and Formula Database is a search engine for mathematical equations.
