John is currently a Ph.D. student in Electrical Engineering at MIT. In 2018, he received a B.S. in Electrical Engineering with a minor in Physics from the University of Illinois at Urbana-Champaign. In the past he has done work with spray and blade-coated perovskite solar cells, plasma-assisted molecular beam epitaxy for GaN growth, fabricating block copolymer nanostructures, oncology, and on novel AFM sensing modes. His current work is with the quantum electron microscope project, and in his free time he enjoys hiking, running, and sailing.
