London, England

Shireen is a Consultant Hematologist and Honorary Senior Lecturer at King’s College Hospital, London with a specialist interest in the treatment of patients with lymphoma (cancer of the lymphatic system). She is also passionate about promoting plant-based nutrition for the prevention and reversal of chronic diseases and for maintaining optimal health after treatment for cancer.

She qualified as a medical doctor in 2000, initially training in general medicine, and gaining Membership of the Royal College of Physicians (MRCP; 2003). She then specialised in Haematology and achieved Fellowship of the Royal College of Pathologists (FRCPath; 2008). During training, she took time out to undertake a PhD (University of London, 2011). Her research investigated the role of selenium, an essential micronutrient, in sensitising cancer cells to chemotherapy. She was able to show that supra-nutritional doses of selenium could enhance the action of chemotherapy in the laboratory. She has published a number of peer-reviewed papers in the field of lymphoma.

Shireen discovered the power of nutrition for the prevention and treatment of disease in 2013 and since then has been following a whole food plant-based diet. She has immersed herself in the science of nutrition and health and completed the eCornell certification in plant-based nutrition. In 2019 she became certified as a Lifestyle Medicine Physician by the International Board of Lifestyle Medicine. She is also a certified CHIP (Complete Health Improvement Program) practitioner.

Shireen founded Plant-based health professionals UK in 2017 in order to bring evidence-based education on plant-based nutrition to the UK. Since then she has been appointed as Visiting Professor of Plant-Based Nutrition at Winchester University where she has developed and facilitates the UK’s only University-based CPD-accredited course on plant-based nutrition for healthcare professionals. In January 2021, Shireen co-founded and launched the UK’s first CQC registered, online, multi-disciplinary, plant-based lifestyle medicine healthcare service, Plant Based Health Online.
