Unnikrishnan Sivan

M.Sc., Ph.D.

Postdoctoral Researcher in Cancer and Vascular Biology

Dr. Sivan's research career started as a Ph.D. scholar in 2007 and successfully completed his Ph.D. (2014) in stem cells and regenerative medicine from SCTIMST, Trivandrum.

Dr. Sivan's desire to study in vivo stem cell biology led him to the Karolinska Institutet, Stockholm, Sweden. As a postdoctoral fellow at Karolinska (2014-2018), he was exploring how a cancer-initiating (stem) cell exploits the standard homeostasis mechanisms and micro-niches, for the benefit of their survival and spatial organization during carcinogenesis.

Gradually Dr. Sivan got interested in understanding the role of stem cell niche in tissue regeneration, carcinogenesis, and metastasis, which brought him to the Kennedy Institute of Rheumatology, at the University of Oxford.
