These outputs include the prophetic insight into the treatment of neurological disease, Handbook of Behavior, Food and Nutrition (2011), Nanomedicine and the Nervous System (2012), Oxidative Stress and Dietary Antioxidants in Neurological Disease (2020), Zika Virus Impact, Diagnosis, Control and Models (2021), Factors Affecting Neurodevelopment: Genetics, Neurology, Behavior and Diet (2021), Diagnosis and Treatment of Spinal Cord Injury (2022), The Neurobiology, Physiology, and Psychology of Pain (2022) and The Handbook of Lifespan Cognitive Behavioral Therapy: Childhood, Adolescence, Pregnancy, Adulthood, and Aging (2023). Professor Martin is particularly interested in all aspects of the relationship between underlying physiological substrates and behavior, particularly in how these relationships manifest in both acute and chronic psychiatric disorder. He has published original research germane to significant mental health disorders including the areas of schizophrenia, anxiety, depression, self-esteem, alcohol and drug dependency, high secure forensic mental health and personality disorder. He has a keen interest in the impact of postviral illness and is actively involved in clinical research post-Covid pandemic and in particular, the impact of Long Covid on psychological, neurological, physiological and social functioning.

Rajkumar Rajendram

Dr Rajkumar Rajendram is a clinician scientist with a focus on internal medicine, anaesthesia, intensive care and peri-operative medicine. He graduated with distinctions from Guy’s, King’s and St. Thomas Medical School, King’s College London in 2001. As an undergraduate he was awarded several prizes, merits and distinctions in pre-clinical and clinical subjects.

Dr Rajendram began his post-graduate medical training in general medicine and intensive care in Oxford. He attained membership of the Royal College of Physicians (MRCP) in 2004 and completed specialist training in acute and general medicine in Oxford in 2010. Dr Rajendram subsequently practiced as a Consultant in Acute General Medicine at the John Radcliffe Hospital, Oxford.

Dr Rajendram also trained in anaesthesia and intensive care in London and was awarded a fellowship of the Royal College of Anaesthetists (FRCA) in 2009. He completed advanced training in regional anaesthesia and intensive care. He was awarded a fellowship of the Faculty of Intensive Care Medicine (FFICM) in 2013 and obtained the European diploma of intensive care medicine (EDIC) in 2014. He then moved to the Royal Free London Hospitals as a Consultant in Intensive Care, Anaesthesia and Peri-operative Medicine. He has been a fellow of the Royal College of Physicians of Edinburgh (FRCP Edin) and the Royal College of Physicians of London (FRCP Lond) since 2017 and 2019 respectively. He is currently a Consultant in Internal Medicine at King Abdulaziz Medical City, National Guard Heath Affairs, Riyadh, Saudi Arabia.

Dr Rajendram’s focus on improving outcomes from Coronavirus Disease 2019 (COVID-19) has involved research on point of care ultrasound and phenotypes of COVID-19. Dr Rajendram also recognises that nutritional support is a fundamental aspect of medical care. This is particularly important for patients with COVID-19. As a clinician scientist he has therefore devoted significant time and effort into nutritional science research and education. He is an affiliated member of the Nutritional Sciences Research Division of King’s College London and has published over 400 textbook chapters, review articles, peer-reviewed papers and abstracts.
