Jason Chou

PhD Candidate

Jason Chou

Jason joins the SLAC HEDS team as a second-year Ph.D student in Stanford physics department. He went to National Taiwan University and graduated with a B.Sc. in physics. The lovely, small tropical island of Taiwan has made him a committed nature lover. He fixes his eyes on birds when not on physics books; he sings music when not speaking physics. The curious heart has found its way to the study of laser-plasma interactions, where he pursues fundamental and in-depth understanding of the HED science. Being bewitched by the profoundness, he has recently decided to become a theorist, aiming at a thorough grasp of the physics and wishing to challenge the unknown.

The projects he’s working on right now include probing ion acceleration mechanisms in laser-solid interactions through computer simulations and bridging with accelerator physics through integrated applications.
