Dr Tziotzios obtained his medical qualifications from the University of Cambridge. He undertook Academic Foundation Training and completed his Core Medicine Training at Cambridge University Hospitals before competitively being appointed Academic Clinical Fellow in Dermatology at St. John’s.
He developed an interest in molecular genetic research and hair disorders and secured substantial research grant funding in order to undertake doctoral research into dissecting the molecular pathogenesis of a highly distressing type of scarring hair loss affecting women. His PhD research at St. John’s has culminated in high-impact publications, including an original article in Nature Communications, and several distinctions such as the BAD Whimster Prize, the Wycombe Prize, RSM Dermatology Research Prize and the NIHR/BAD Award.
He remains active in basic and clinical research: he has recently been awarded the BSF Young Investigator Award and leads a UK-wide research consortium investigating lichenoid, scarring and alopecic disorders. He is also the National (UK) Chief Investigator for the ALLEGRO studies into a novel and promising class of medicines for alopecia areata.
