I am a medical scientist interested in building translatable solutions that bring advanced medical care to more people.


During my time in the Edelman Lab at MIT, 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 MicroPort, I aim to bring medical devices that are effective and affordable for more sustainable healthcare around the world. At X-COR Therapeutics, we have tackled both accessibility and affordability by developing a medical device for the treatment of respiratory failure with ease-of-use and cost in mind from the beginning. In the past, I have also spent time at DOE NETL.


I am based in Boston, MA and am passionate about sustainable healthcare and educational outreach. I am an associate editor and peer reviewer for the Journal for Emerging Investigators, which serves as an avenue to encourage and educate the next generation of scientists through publication. I also volunteer with Boston Partners in Education as an academic mentor at Boston Arts Academy to help high school students in STEAM subjects. In my free time, I enjoy cooking, dragon boat racing, and mountaineering.
