Medicinal chemist with experience in oncology and rare diseases. Most recently designing heterobifunctionals in the emerging field of Targeted Protein Stabilisation to restore function in pharmacoresistant cystic fibrosis. This multidisciplinary effort harnessed biophysics, biochemistry, chemistry, cell and structural biology to identify non-inhibitory chemical matter for deubiquitinases. Previously, working on synthetic lethality oncology targets Mat2A and Werner Helicase, designing and executing synthetic routes using structure based drug design and multi-parameter optimisation led to the discovery of Mat2A inhibitor IDE397, currently in Phase 2 trials.
