Sam Grayer

Sam holds a first class masters degree in Chemistry from the University of Oxford. During the third year of his degree, he completed a summer internship at BP Chemicals, where he researched the Fischer‑Tropsch process.  His final year masters project involved developing hypoxia-activated prodrugs to selectively target hypoxic tumour cells. On completion of his undergraduate degree, Sam enrolled on a DPhil at the University of Oxford. His research focused on the development of probes for glutathione-gated bacterial potassium efflux systems (Kef). Kef shows potential as a novel antibiotic target and Sam’s work demonstrated for the first time that small molecules targeting Kef exhibit antibacterial activity. The project involved cycles of computational chemistry, organic synthesis, protein expression and purification, and the development of various biophysical assays.

Sam joined Carpmaels & Ransford as a trainee patent attorney in 2015.

Outside the office, Sam enjoys playing squash, running and going to the theatre.
