I help build medical devices that bring better medical therapies to more people. I am trained in medicine and biomedical engineering, and currently serve as the Co-Director of Micracle Point.


At MicroPort, I currently serve as the Co-Director of Miracle Point in North America to evaluate and develop new emerging medical technologies through the proven Miracle Point pipeline. I have previously spent time in the Edelman Lab at MIT, where I studied device-organ interactions to make mechanical circulatory support more accessible for the treatment of heart failure. The results of my work are now clinically deployed as the Impella SmartAssist. At X-COR Therapeutics, I helped develop a new medical device for the treatment of respiratory failure with ease-of-use and accessible cost in mind from its inception. In the past, I have also spent time at DOE NETL.
