Assistant Professor of Chemistry
John Stedman Magyar, assistant professor of chemistry, joined the Barnard faculty in 2007. Professor Magyar is a bioinorganic chemist with strong interests in environmental chemistry and biogeochemistry.
At Barnard, Magyar and his undergraduate research students are investigating the molecular details of trace metal uptake and homeostasis in environmentally important microorganisms, such as marine phytoplankton and methanogenic archaea. They are working to elucidate the relationships between microbial trace metal processing and global biogeochemical cycles. The Magyar group also is exploring molecular mechanisms of cold adaptation, specifically in the hydrocarbonoclastic, psychrophilic bacterium Colwellia psychrerythraea.
Current work in the Magyar group is primarily funded by a grant from the National Science Foundation (CHE-1308170) and by a Barnard College Presidential Research Award.
Prior to joining Barnard, Professor Magyar was a postdoctoral scholar in chemistry at the California Institute of Technology, where he studied electron transfer kinetics and protein dynamics. Professor Magyar's doctoral research, at Northwestern University, provided important insights into the molecular mechanisms of lead(II) poisoning.
