Principal Process Engineer @ WD

About

I am a material chemist skilled in nanomaterial synthesis and characterization, optoelectronic device fabrication and testing, and single-particle fluorescence imaging. I am proficient in various material characterization methods (i.e., HR-TEM, STEM, SEM, EDS, c-AFM, super-resolution fluorescence microscopy, PL spectroscopy, PLQY, PL lifetime, UV-Vis spectroscopy, film profilometer etc.). I have significant experience in transforming initial ideas into major research projects and collaborating with theorists, physicists, and engineers on interdisciplinary projects.
