R. Fraser Armstrong

R. Fraser Armstrong is a prominent British chemist known for his pioneering work in the field of bioinorganic chemistry. He is a professor at the University of Oxford and a fellow of St John's College. Armstrong's research primarily focuses on the mechanisms of metalloenzymes and the development of new methods for studying enzyme catalysis.

Early Life and Education

R. Fraser Armstrong was born in the United Kingdom. He completed his undergraduate studies in chemistry at the University of Leeds. He then pursued his doctoral studies at the University of Oxford, where he earned his PhD under the supervision of R. J. P. Williams.

Career

After completing his PhD, Armstrong held postdoctoral positions at the California Institute of Technology and the University of Cambridge. He later joined the faculty at the University of Oxford, where he has made significant contributions to the field of bioinorganic chemistry.

Research

Armstrong's research is centered on understanding the function of metalloenzymes, which are enzymes that contain metal ions as cofactors. His work has provided insights into the mechanisms of hydrogenases, nitrogenases, and other important enzymes. He has developed innovative techniques for studying enzyme catalysis, including the use of protein film voltammetry.

Hydrogenases

One of Armstrong's major research areas is the study of hydrogenases, enzymes that catalyze the reversible oxidation of hydrogen. His work has elucidated the electronic and structural properties of these enzymes, contributing to the development of biohydrogen production technologies.

Nitrogenases

Armstrong has also made significant contributions to the understanding of nitrogenases, enzymes that catalyze the reduction of dinitrogen to ammonia. His research has provided valuable insights into the enzyme's active site and the mechanism of nitrogen fixation.

Awards and Honors

R. Fraser Armstrong has received numerous awards and honors for his contributions to chemistry, including:

• The Royal Society of Chemistry's Tilden Prize
• The Royal Society's Davy Medal
• Election as a Fellow of the Royal Society (FRS)

Personal Life

Armstrong is married and has children. He is known for his dedication to teaching and mentoring the next generation of chemists.
