Imperial College, London


Dr. James Choi leads the Noninvasive Surgery & Biopsy Laboratory at Imperial College London, which develops new ultrasound methods that noninvasively control mechanical stimuli, and studies ultrasonic bioeffects.

His laboratory focuses on short-pulse and low-intensity ultrasound therapy and imaging technologies, engineering every aspect of the control pathway: device design, pulse sequencing, physical and biological responses, pulse monitoring, and control. The new control technologies are then used to improve the safety and performance of both existing and novel therapeutic and diagnostic effects.

His applications include drug delivery across capillaries and into cells; acoustic micro pumping in tissue; and elasticity imaging at super-resolution.
