Welcome to Bob’s website!
My name is Sangjoon Bob Lee. I am a PhD student in Materials Science and Engineering at Stanford University, advised by Prof. Colin Ophus.
I study crystalline and amorphous materials with electron microscopy. I tackle the bottlenecks of 4D-STEM one at a time, across computing, data, experiment, and design.
I can be found on GitHub and Google Scholar. My electron microscopy learning and tutorials are here.
