Dr Margulis is a pharmacist and a chemist by training. Her PhD thesis centred on designing drug delivery systems for poorly water-soluble pharmaceutics. In her postdoctoral research at Stanford University, she employed mass spectrometry imaging to study a variety physiological processes in living tissues, and to guide drug discovery and drug delivery. This work convinced her that mass spectrometry imaging can provide answers to many essential questions in modern medicine and pharmaceutics. Dr Margulis is supervising a project in the next round.
