Hi! I am a Computer Scientist with the Machine Intelligence Group at Lawrence Livermore National Laboratory (LLNL), a Federally Funded Research Institute. My research interests broadly include computer vision, machine learning, and high dimensional data analysis.
I’m fortunate to be able to collaborate with scientists and researchers across several areas of science and engineering — for example high energy physics; epidemiology for COVID19; x-ray imaging; human connectome project; healthcare.
I spend a lot of my time thinking about modeling and understanding high dimensional, multi-modal, and inherently structured data. I serve as a reviewer for several top machine learning and computer vision publications (NeurIPS, CVPR, ICLR, ICCV, ICML, AAAI. etc).
I also lead the Open Data Initiative with the goal of releasing LLNL’s high impact scientific datasets for machine learning — so far, we have 9 datasets and counting!
