Brian Lee

Ph.D. Student
Brian Lee

Brian graduated with a B.S. degree in Electrical and Computer Engineering, Magna Cum Laude, at Cornell University in 2015. He first joined the group in 2014 as an undergraduate researcher to engage in a project with Aseema and Steven on developing effective integrated metal heaters for silicon nitride waveguides. He then moved to Columbia University with Professor Lipson and the group to pursue his Ph.D. in Electrical Engineering. Brian initially matriculated to Cornell as a Biology major in the College of Arts and Sciences, but his enthusiasm for optics and nanophotonics were sparked from one of his favorite courses at Cornell, AEP 1100 "Lasers and Photonics," and transferred to the College of Engineering during his sophomore year to further explore his interest for optics. He first met Professor Lipson in a class she taught at Cornell, ECE 4370 "Fiber and Integrated Optics," and joined the group. Because of his father's occupation, Brian has lived in six different countries, South Korea, Czech Republic, Switzerland, Thailand, Bangladesh and France. Brian can speak Korean and French. His biggest role models are Richard Feynman and Michelangelo.
