Greetings! My name is Le Ho, a second-year Ph. D. candidate in the Electrical and Computer Engineering Department at Stony Brook University. After completing my Master’s Degree in 2019, I had an excellent opportunity to work in the Novel Medical Imaging Technologies lab and pursue my interest in solid-state devices. My research includes fabrication and characterization of amorphous selenium photodetectors and performing simulations at the device level using Atlas, Silvaco simulator to find ways to improve the performance of avalanche a-Se detectors.
