Biography. I am currently an Associate Professor in the School of Data Science and Society (SDSS) at the University of North Carolina at Chapel Hill. Prior to joining SDSS, I was a Senior Scientist in the Earth and Environmental Science Division at Los Alamos National Laboratory, where I served from 2010 to 2024. I received my Ph.D. in Applied and Computational Mathematics from Arizona State University in 2010.
Research. My current research focuses on scientific machine learning (AI for Science), deep learning, computational methods, and their applications in medical imaging, signal and image Analysis, and geoscience. Specifically, I have worked on ultrasound imaging and cancer detection, subsurface imaging for energy exploration,and time series classification for small earthquake detection.
Ph.D. /Master Openings (Fall 2026). We invite applications for Ph.D./Master positions starting in Fall 2026. Prospective students interested in advancing cutting-edge research in this field are encouraged to Apply to the position that best matches their background and interests.
Intern Openings (Spring & Summer 2026). We also welcome applications for PAID research internships in Spring and Summer 2026. Interested candidates should complete the Application Form and Apply to the role most relevant to their skills and interests.
