John Vant is a Ph.D. candidate in the Singharoy Group. In the Spring of 2018, John graduated from Eastern Washington University with a B.S. in Chemistry and Biochemistry focusing in physical chemistry. At Eastern John received a full ride from the Carper Foundation Graduate Preparation Scholarship and was a 2017-2018 Frances B. Huston Medallion Award winner. During the summer of 2018, John was a guest researcher in the DOE’s Visiting Faculty Program where he conducted high-resolution infrared spectroscopy research on ozone-depleting substances from which publications are currently pending approval.  Since arriving at ASU John has developed molecular dynamics methods for building atomic models from cryo-EM data and made significant discoveries in bioenergy.  John has also been selected as an NSF Graduate Research Fellow for his proposal on a “Periodic table of F-type ATPases”.
