About

Richard Helm is an Associate Professor at Virginia Polytechnic Institute and State University in the United States. His research encompasses a range of topics, including the roles of peptidoglycan transpeptidases in Clostridioides difficile, the effects of copper on Legionella pneumophila, and the biochemical pathways of Chlamydia trachomatis. Additionally, his work explores the metabolic impacts of olive-derived compounds and the molecular mechanisms underlying protein aggregation and memory formation in relation to sex differences.
