Dr. Sarah Shepherd

Sarah Shepherd studied for a MChem degree in Chemistry with Medicinal Chemistry  at the University of Warwick from 2006-2010. During her fourth year MChem project, her research involved the synthesis of inhibitors of carotenoid cleavage dioxygenases, under the supervision of Professor Tim Bugg.

Sarah joined the Micklefield group in 2010 and has achieved a PhD in the area of biocatalysis. Sarah is researching halogenase enzymes that chlorinate and brominate aromatic substrates. Sarah has experience in cloning and mutagenesis, protein purification and expression and analytical techniques such as, HPLC, mass spectrometry and NMR. She led NPRONET (Natural products discovery and bioengineering network) as a Network Manager and is currently a Project Manager for the group

Outside of the lab, Sarah enjoys playing golf and spending time at the beach.
