Research profile

Rational discovery of new therapeutics relies on having a good understanding of the mechanism of action of a drug and how this relates to its effectiveness.


Dr Gregory is an early career researcher (PhD, 2009) with a strong expertise in the pharmacology of G protein-coupled receptors (GPCRs) and an international profile in the study of GPCR allosteric modulation and stimulus-bias. Dr Gregory returned to Australia in August 2013 to join the Drug Discovery  Biology  theme  at  Monash Institute of Pharmaceutical Sciences, where she is building her research team. Her research focuses on metabotropic glutamate receptor 5, a promising drug target for the treatment of a variety of CNS disorders including schizophrenia, depression, autism and Alzheimer's disease.  She  has  authored  17 original research papers and is currently an NHMRC CJ Martin Biomedical Research fellow.
