We are a team of clinician scientists working at the Royal Free Hospital and University College London.


Lead: Dr Daniel Martin, OBE


Dan is a Reader in Perioperative and Critical Care Medicine at University College London and Honorary Consultant in Critical Care Medicine at the Royal Free Hospital.

Perioperative Research Fellow: Dr Jia Stevens

MBBS, MA(Cantab), FRCA

Jia is an anaesthetic registrar, currently undertaking a PhD investigating the metabolic responses during the perioperative period. Her current project ‘COSMOS’, investigates the relationship between cardiopulmonary fitness, mitochondrial function and oxidative stress with outcomes after major surgery.

Intensive Care Research Fellow: Dr Helen McKenna

MBBS, MA(Cantab), MRCP

Helen is an anaesthetist and intensive care research fellow at the Royal Free Hospital. She is undertaking a PhD investigating mitochondrial and microcirculatory function and nitric oxide metabolism in critically ill patients.  Other interests include the application of clinical chronobiology to improve health.

Research Scientists

Dr Gavin Jell

BSc, MSc, PhD, PG Cert

Gavin is a Senior Lecturer, at the division of surgery and interventional sciences at University College London. He leads a research group focused on understanding how materials interact within biological environments, in order to create “better” biomaterials; materials that have reduced failure rates and have increased functionality (e.g. promote regeneration). He is an interdisciplinary scientist who completed a BSc in Biology, an MSc in Parasitology before becoming interested in the material – biological interactions and completing a PhD (at UCL as part of the Queen Mary IRC in Biomedical Materials) looking at the causes of aseptic loosening of  orthopaedic implants. Gavin has a particular interest in nanoparticle toxicity, nanoparticle cellular interactions and HIF-1 alpha stabilising materials.  He is also the programme lead for the MSc in Nanotechnology & Regenerative Medicine, and course founder and director for the BSc/MSci in Medical Innovation & Enterprise.

Medina Guliyeva

BSc, MSc


Medina is a doctoral researcher at the UCL Centre for Nanotechnology & Regenerative Medicine. Her main scientific interest is to understand how nanoparticle physicochemical properties change biological interactions in different biological environments. She is skilled in a wide range of life/medical science fields from neuroscience to regenerative medicine and nanomedicine.

Research Nurses


Helder Filipe


Helder is a senior research nurse at the Royal Free Hospital. He is in charge of coordinating and delivering a number of studies across both intensive care and anaesthesia.

Margaret McNeil


Margaret is a research nurse on the intensive care unit at the Royal Free Hospital. She has experience of clinical intensive care nursing prior to undertaking the research post. She is part of the team involved in co-ordinating and delivering several research studies across both intensive care and anaesthesia.
