Profile

Rayomand Khambata obtained a first-class undergraduate Masters in Pharmacology from the University of Bath in 2006. He then joined Professor Adrian Hobbs’ group at University College London and completed his PhD in pharmacology which involved investigating the role of C-type natriuretic peptide on vascular homeostasis. After obtaining his PhD in 2010 he started a post-doc with Professor Amrita Ahluwalia at the William Harvey Research Institute, to investigate the role of inorganic nitrate on atherosclerosis. During this time his research has focussed on the role of inorganic nitrate on the cardiovascular system, with a focus on inflammation. In 2020 he was appointed as a Lecturer. 

Rayomand is an academic advisor and module lead for Drug design, a 3rd year module on the BSc Pharmacology and Innovative Therapeutics programme. He is also involved in various teaching on the MBBS/Biomedical Sciences and Masters programmes. In 2021 he was appointed as Head of Year 3 for BSc Pharmacology & Innovative Therapeutics.

Summary

The major focus of the Vascular Pharmacology group is the bioactivation of inorganic nitrate to nitrite and subsequently nitric oxide. My research focusses on the potential anti-inflammatory effects of inorganic nitrate and nitrite in the setting of cardiovascular diseases.
