What I build, what I publish.

A bias toward problems where physics, signal processing and clinical constraints meet.

Core focus

USCT Image reconstruction Ultrasound physics HIFU therapy FPGA front-end Numerical simulation

At Lily MedTech, contributed to the development and 2021 commercial release of COCOLY, a ring-array USCT scanner for breast imaging. Led several internal R&D projects on novel imaging methods.

PhD work proposed a dictionary-based reconstruction method that delivers high-resolution USCT echo images under reduced data acquisition — a path toward faster, cheaper scans.
