Sally-Ann Poulsen

Sally-Ann Poulsen is an Australian chemical biologist who is a Professor and Director at Griffith University. Her research considers medicinal chemistry and drug discovery. She is Chair of the Royal Australian Chemical Institute Medicinal Chemistry and Chemical Biology Division.

Early life and education Poulsen grew up in a rural community in Australia. She attended a small primary school of only seventeen students and one teacher. She was the highest achieving student of her school. After completing high school, Poulsen got a job, and eventually decided to go to university. Poulsen was an undergraduate student at Griffith University, where she was a university medallist. She was the first member of her family to complete higher education. During her bachelor's degree she started to study pyrazolo [3,4-d] pyrimidines. Poulsen remained at Griffith University for her graduate studies, where she continued to study pyrimidines, looking for structure-function relationships in their binding to adenosine receptors. After earning her doctorate, Poulsen moved to the United Kingdom, where she was a postdoctoral researcher at the University of Cambridge and AstraZeneca. She proposed that adenosine receptors offered novel opportunities of drug design.

Research and career Poulsen returned to Australia, where she joined the University of Queensland as a Royal Society National Health and Medical Research Council research fellow. Amongst various medical conditions, Poulsen investigated drug resistant brain cancer. Such cancers are typically treated with temozolomide, but they can become resistant over time. Poulsen demonstrated that it is possible to reverse this resistance by blocking the proteins alongside pumps on the surface of glioblastoma cells, which allow the temozolomide to exit the glioblastoma before it reaches high enough levels to destroy the cancer. In March 2021 Poulsen was appointed Deputy Director of the Griffith Institute for Drug Discovery. She is an Associate Editor of MedChemComm.
