Jun Hong Park (2022-2025) - Jun Hong joined the lab as a postdoc and worked on microbubble-mediated delivery of drug loaded nanoparticles for both hepatocellular carcinoma and retinoblastoma. He also adapted the double-difference method from geophysics to passive cavitation imaging in the context of differentiable beamforming. Jun Hong was a main conduit of collaboration with other labs seeking to use therapeutic ultrasound in their research. Jun Hong is currently an assistant professor at Hankuk University of Foreign Studies in the Department of Biomedical Engineering.
Thurston Brevett (2019-2025) - Thurston joined the lab as a PhD graduate student in Electrical Engineering and worked on projects related to sound speed estimation.
