Ph.D. in Environmental Engineering, University of Michigan, 2021.
M.S. in Bioinformatics, University of Michigan, 2021.
M.S. in Environmental Engineering, Konkuk University, 2015.
B.S. in Environmental Engineering, Konkuk University, 2013.


My research interest is in environmental microbiology, synthetic biology, and bioinformatics, specifically learning the mechanisms of microbial metabolism and interactions for environmental, industrial, and medical applications. I am currently working in projects that involve the use of methylotrophs to separate rare earth elements from waste materials and development of measures to contain genetically engineered microorganisms in the environment post-deployment.
