Sean McClory, Ph.D.

Assistant Professor
Holroyd Hall 227

Before arriving at La Salle, Dr. McClory was a Postdoctoral Fellow at the University of Pennsylvania, where he studied how genes are regulated in the human immune system by a process known as mRNA splicing, and served as a visiting assistant professor at Kenyon College. Dr. McClory earned his PhD from Ohio State University, where he studied the structure and function of RNA in ribosomes – targets of many important antibiotics.

RNA is a unique and versatile molecule, playing important roles in almost every aspect of life. Currently, Dr. McClory’s laboratory is investigating how an RNA sequence in bacteriophages causes a Programmed Translational Frameshift (PTF) – which allows these bacterial viruses to produce multiple proteins from a single gene. Understanding PTF will provide insights into how bacteriophages have evolved to infect different bacteria, which will aid in the development of therapeutic bacteriophages as an alternative to antibiotics.
