I am a second year student at UC Berkeley majoring in Molecular & Cell Biology and Business Administration. I am incredibly passionated about the healthcare industry. I hail from Chicago, Illinois, the best food city in the world. If you ever need any restaurant recommendations, I'm the person to go to! When I'm not spending time in my classes, I enjoy debating pressing issues in UCBMUN, collaborating with healthcare related companies in Phoenix Consulting, experimenting on my watercolor paintings, and initiating spontaneous dance breaks.
