David J. Kelly

Professor David Kelly is Emeritus Professor of Microbial Physiology at the University of Sheffield, UK. He has >35 years research expertise in bacterial physiology and biochemistry, membrane protein transport processes and bioenergetics, and has wrked with the zoonotic food-borne pathogen Campylobacter jejuni for >25 years. A major program to study C. jejuni physiology was carried out in his laboratory, in particular the responses to oxygen, many aspects of carbon metabolism and functional analysis of the electron transport chains. He has long-standing interests in membrane transport mechanisms and in the 1990s discovered an entirely new class of periplasmic binding-protein dependent prokaryotic solute transporters, the TRAP transporters, now known to be common in a diverse range of bacteria and archaea. He has published >150 papers (h-index 2024 = 56), held numerous grants, served on grant committees and has been a regular invited speaker at national and international conferences. He is the recipient of a Leverhulme Emeritus Fellowship from the Leverhulme Trust, UK.
