About Me
My Story
From Kathmandu to the lab bench. I grew up in Kathmandu, Nepal, and completed my undergraduate degree in Physics at Tribhuvan University. That path led me to Taiwan, where an internship turned into a year as a Research Assistant — and later a master's thesis — in Dr. Cheng-Tien Chiang's lab at Academia Sinica. There, I built a non-collinear optical parametric amplifier (NOPA) from scratch, engineering it into a working light source for photoelectron spectroscopy.
Now, at Stony Brook. I'm currently a PhD student in Prof. Thomas Allison's lab, where I design and build ultrafast experiments and turn the data they produce into physical insight — work at the intersection of instrumentation and discovery.
Outside the lab, I read non-fiction and the news, hike, play football, cycle, travel, and cook — the same curiosity that shows up in the lab too.
I build the optical tools that let us watch electrons move — designing light sources and experiments that resolve dynamics on femtosecond timescales.
