Research Overview

Our work focuses on both basic research and translational research in the development of novel tools, imaging, and robot control techniques for medical robotics. Specifically we investigate methodologies that (i) increase the smartness and autonomy and (ii) improve image guidance of medical robots to perform previously impossible tasks, improve efficiency, and improve patient outcomes.

Smart Surgical Systems

Increased autonomy has transformed fields such as manufacturing and aviation by drastically increasing efficiency and reducing failure rates. While pre-operative planning and automation has also improved the outcomes of surgical procedures with rigid anatomy, practical considerations have hindered progress in soft-tissue surgery mainly because of unpredictable shape changes, tissue deformations, and motions limiting the use of pre-operative planning. 

Image Guided Interventions and Planning

Diagnostic imaging has dramatically improved over the years, where now small tumors and defects are often detectable before affecting a patient’s health. However, in many cases imaging during intervention and surgery is limited to basic color cameras, resulting in missed tumors and sub-optimal surgical results. 

Cardiac Surgical Planning

For complex congenital heart disease (CHD) involving a single
functioning ventricle, the Fontan operation is performed which results
in a circulation where deoxygenated venous blood passively flows into the
pulmonary arteries without a ventricular pump. However, conventional
Fontan graft designs may result in suboptimal cardiovascular emodynamics leading to post-surgical complications.

Novel Robotic Actuators

We are developing new actuation schemes for precision guidance of needles and other surgical implements that will allow for complex procedures such as Deep Anterior Lamellar Keratoplasty (DALK) to be performed faster and more precisely, using robotic methods.

Autonomous Ultrasound Robotic System

Unintentional injury or trauma is among the leading causes of death in the United States with up to 29% of pre-hospital trauma deaths attributed to uncontrolled hemorrhages. 

Flycycle Course Integration

The Flycycle is a unique virtual reality based system that integrates both upper and lower body workout through a 2 degrees-of-freedom platform
