Education:
Brandon received his B.S. in Chemistry at Washington State University in 2009 where he developed a profound interest in biochemistry and biophysics. He pursued a Ph.D. in Chemistry at Emory University studying abiotic-biotic interfaces for photocatalysis, the enzymatic mechanisms of hydrogenases, and proton-coupled electron transfer (PCET) dynamics at bioinorganic cofactors in the group of R. Brian Dyer. He then pursued postdoctoral studies at Harvard/Massachusetts Institute of Technology defining the targets of allosteric control and conformational gating that initiate long-range radical transfer during nucleotide metabolism by ribonucleotide reductase in the labs of Daniel G. Nocera (Harvard) and JoAnne Stubbe (MIT).
