Liesl Janssens is a PhD Student at the laboratory of Toxicology at Ghent University. She joins us again in this episode to give us an update on her research focused on developing new detection methods for Hypoxia-inducible factor (HIF) stabilizers. She also discusses recent work that she and her colleagues have been doing to characterize and detect cannabinoids, opioids, and psychedelics using similar activity-based assays.
