Ramish Ashraf, PhD


I grew up in Lahore, Pakistan where I did my bachelor’s in electrical engineering and transitioned into a PhD in Medical Physics at the Thayer School of Engineering at Dartmouth College. My PhD work was primarily on beam monitoring and dosimetry for small fields and FLASH radiotherapy. In my free time, I like to watch cricket, soccer, and hike and listen to all kinds of music.
