Our Group

Research in our laboratory is focused on the design, fabrication, and testing of ultrasonic frequency piezoelectric transducers and associated electronic hardware for medical applications. Specifically, we are focused on developing miniaturized ultrasound imaging endoscopes and miniaturized ultrasound therapeutic devices using an in house micro-fabrication facility targeting minimally invasive surgical applications.

Minimally invasive surgical approaches in comparison to open surgery, offer drastically improved patient outcomes including less blood loss, fewer complications, reduced recovery time, and a reduced chance of infection. To allow more procedures to be performed as minimally invasive, it’s important to develop new surgical tools specific to the minimally invasive surgical procedure. As these procedures are almost always performed through a very small incision or access route, the associated tools must be developed in a miniaturized form factor.
