Massachusetts Institute of Technology

Graduate Student



Jeehyun Yang was born and raised in South Korea until high school and then moved to Japan for his undergraduate in Resource Engineering from Hokkaido University in Sapporo. He first began laboratory research as an undergraduate, studying the hydrothermal alteration of iron-chromium hydroxide into spinel structure.

For his Ph.D., he first joined Professor Ono group in the department of Earth, Atmospheric and Planetary Sciences (EAPS) at MIT. In Ono group, he has been focusing on photochemical experiment that might be able to reproduce a certain pattern of quadruple Sulfur isotope signal preserved in sedimentary rocks older than 2.3 billion years ago.

In Green group in the department of Chemical Engineering, Jeehyun is investigating bottom-up Polycyclic Aromatic Hydrocarbon (PAH) formation using Photoionization-Time of Flight Mass Spectrometry (PI-TOF-MS). Previously in his college, he was in a ski team ‘Circle for Elegant Skiing’ and here now at MIT, he enjoys playing Ice hockey.
