Career Info


I am a PhD physicist currently working on the development of particle accelerator technology for medicine and other industrialization with a focus on miniaturization and cost reduction. In the past, I focused most on producing high brightness electron beams using high gradient accelerating cavities and high brightness cathodes enabled by cryogenic operation. Below are several documents most relevent to give a picture of my interests and experience.
