Studying at Cambridge


Dr Ravin Jugdaohsingh


I have a BSc (Imperial College London), MSc (University College London) and a PhD (King’s College London) in Chemistry. My PhD study was on characterizing the interactions between amorphous silica (soluble and polymeric/nanoparticulate) and aluminium to understand how silica could act as a natural antidote to aluminium toxicity (a potential bone, renal and neuro-toxin). Subsequently I carried out post-doctoral research at King’s College London and MRC Human Nutrition Research in Cambridge on dietary silicon intake and metabolism, and investigating its potential role in bone and connective tissue health.

Visiting worker at MRC Elsie Widdowson Laboratory (Cambridge, UK).

Research Interests

My expertise is on the chemistry and biochemistry of silicon and the effect of the element on human health. I have a particular interest in the role and mechanisms of action of silicon in connective tissues as well as cell interactions and impact of mineral silica nanoparticles. Much of my work has been on bone, in understanding the role silicon may play in the maintenance of normal bone health.
