Suganiya Raveendran, secretary


Dr Dumitru graduated from medical school in 2001. She trained as a specialist in allergy and clinical immunology from 2002 to 2007 in Bucharest. She received an academic research fellowship to join the clinical allergy and immunology department at Imperial College London (2008-2011) which enabled her to complete her PhD in 2011. This was followed by a clinical fellowship in allergy at the Royal Brompon Hospital (2011-2014) and locum consultant position at Guy's and St Thomas hospitals (2014-2017) and Homerton Hospital (2017) before starting my current job at St Mary's Hospital in 2018.

My research was focused on finding a way to improve and/ or treat debilitating allergic symptoms in patients with seasonal and perennial allergies. I have been part of a prestigious research group at Imperial College London that has explored the role and importance of allergen immunotherapy in patients with hay fever and cat allergy. We performed several clinical trials and published in the most prestigious journals in the last few years. This research has contributed significantly to understanding of the mechanisms underlying the allergic diseases and the response to immunotherapy or desensitization.
