Dr Celine Valant

Celine completed a PhD in Medicinal Chemistry in 2005 at The University of Pharmacy, Strasbourg, France. She then took up a postdoctoral position in molecular pharmacology with Profs. Arthur Christopoulos and Patrick Sexton at Monash University.

Her research focuses on the study of G protein-coupled receptors (GPCRs), where she has established an international profile in the synthesis and study of allosteric ligands at GPCRs. The principal interest of her research is towards understanding different modes of regulating GPCR activity in an effort to identify novel targets or approaches for drug discovery. Her research interests encompass allostery, differential signaling, analytical pharmacology, and drug design.

She is the recipient of an Australian Research Council Future Fellowship, the BPS/ASCEPT Outstanding New Investigator Award, the Denis Wade Johnson & Johnson New Investigator Award, and a 2015 Thomson Reuters Australia Citation & Innovation Award.



Dr David Thal

David received his undergraduate degree in Biochemistry at the University of Texas at Austin (2005). During his senior year he worked in the lab of Kenneth Johnson studying the kinetics of a DNA polymerase. He then moved to Michigan to do his PhD in Chemical Biology at the University of Michigan. There, he worked in the lab of John Tesmer and used biochemistry, pharmacology, and structural biology techniques to understand the regulation of GPCR signalling pathways.

In 2011, he moved to Australia to begin his post-doctoral research under Profs. Arthur Christopoulos and Patrick Sexton to broaden his expertise in GPCR pharmacology and allostery. He is now an ARC DECRA Fellow. His research is primarily aimed at determining the molecular structure and function of proteins, with a particular emphasis on understanding novel paradigms of drug action and design on protein targets that are of therapeutic relevance.

In her current research, she is using synthetic single-domain antibody libraries and in vitro display methods to develop nanobodies. She is interested in conformationally selective nanobodies for structural and pharmacological study of GPCRs with a particular interest in understanding location bias and how receptor localisation within subcellular compartments contributes to signalling. She is also part of the Early and Mid-Career Researchers committee (@EMCR_MIPS) and Her Research Matters initiative (@HRM_MIPS).

Elham Khajehali, Postdoc

Elham received her PharmD from Isfahan University of Medical Sciences, Iran. Elham joined Monash University in 2011 to complete her PhD (2015) studying allosteric modulation and biased signalling at the CB1 cannabinoid receptor. In 2015, she started her postdoctoral research on calcium sensing receptors in the laboratory of Dr. Katie Leach. Elham joined the lab in 2016, and her current research focuses on novel allosteric modulators targeting muscarinic acetylcholine receptors for the treatment of Alzheimer’s disease and schizophrenia.

Simon McKenzie-Nickson, Postdoc
