As a structural biologist, I study the structure of proteins at atomic resolution.

By solving the structure of a protein, we learn how the protein functions, its role in disease processes, and how we might modulate it through structure-guided drug design. This makes structural biology an incredibly useful tool in almost all biological fields.

My current research centres on the structure of proteins known to play an important role in neurodegenerative diseases, such as Alzheimer’s disease. One of our most exciting studies is investigating the structure of proteins presented at the surface of microglia, the brain’s immune cells. We are now developing molecules that can target these proteins to improve the ability of microglia to clear the neurotoxic protein aggregates that underpin Alzheimer’s disease.

My work provides opportunities to collaborate with other excellent research teams in Melbourne and beyond. Currently, I collaborate with groups that focus on cancer research, developing new inhibitors that target the proteins controlling gene expression within cancerous cells.

Structural Biology

We determine the three-dimensional atomic structures of proteins involved in disease, with a focus on neurodegenerative diseases and cancer. These structures help us to explore protein function, as well as to discover new drugs.
