Title: Graduate Student

Area: Biogeochemistry

Research Summary:  Eunah is a graduate student in the Zhang Lab.  She is interested in how cell physiology and biochemistry influence stable nitrogen isotope fractionation during biological nitrogen fixation.  She aims to elucidate how and why isotopic fractionations of nitrogenase isozymes vary.  Currently, she is studying how alterations in the composition and structure of amino acids affect isotope fractionation of Azotobacter vinelandii mutants.  Before joining the Zhang lab she was at the POSTECH (BSc & MSc) and GIST (researcher) in South Korea where she studied marine systems including macrofaunal food web structures, sinking flux of organic matter, and bivalve energy budget.
