Research Interests

Sudipto Roy was educated at some of the most distinguished institutions in India. After schooling from Goethals Memorial in Kurseong, Darjeeling, and La Martiniere for Boys in Calcutta, he graduated with a first class first (honours) in zoology from Presidency College in Calcutta in 1991, and again secured the first position during his M.Sc. studies at the Jawaharlal Nehru University, New Delhi, in 1993. He then moved to the National Centre for Biological Sciences in Bangalore, where he obtained a Ph.D. in developmental genetics, studying the cellular and genetic basis of muscle and neuronal development in the fruit fly, Drosophila, with K. VijayRaghavan. During this period, he travelled to Brandeis University in the US and to Cambridge University, England, as a visiting graduate student. He began post-doctoral studies with Philip Ingham at the Centre for Developmental and Biomedical Genetics at the University of Sheffield, England, in 1998, where he initiated research into vertebrate development using the zebrafish embryo. Dr. Roy has been the recipient of several awards and fellowships from international organizations that include the Company of Biologists (UK), the Wellcome Trust (UK), the Human Frontiers Science Program (HFSP) and the European Molecular Biology Organization (EMBO). In 2002, he was honoured with the prestigious Indian National Science Academy Young Scientist Medal by the President of India, the late Dr. Abdul Kalam. In the same year, he joined the Institute of Molecular and Cell Biology in Singapore as a Young Investigator, and was a Principal Investigator (Assistant Professor) from 2003-2008.

Dr. Roy is currently a Senior Principal Investigator, and is an adjunct Associate Professor with the Department of Biological Sciences and the Department of Paediatrics of the National University of Singapore, and was visiting Professor on sabbatical with the National Institute of Biomedical Genomics, Kalyani, India (Jul-Dec, 2017). Over the years, his science has made important contributions to our understanding of many aspects of developmental biology that include how hox genes regulate muscle patterning in flies, the discovery of blimp1 as a selector gene for zebrafish slow-twitch muscle, the genetic pathways regulating vertebrate myoblast fusion, the identification of Kif7 and Dzip1 as ciliary proteins in the vertebrate Hedgehog pathway and elucidation of the master regulatory roles of the FoxJ1, Gmnc and Mcidas transcription factors in programming ciliary differentiation. His current research utilizes the zebrafish and the mouse to study the mechanistic basis of human diseases, notably those arising from dysfunction of cilia and flagella. In 2012, he was awarded the STAR Employee Award from the Agency for Science, Technology and Research of Singapore (A*STAR) for his achievements and services to scientific research in Singapore. Recently, he has developed a liking for communicating science to the general public through writing, and in 2015 won a merit award at the inaugural Asian Scientist Writing Prize competition. In 2016, he was conferred the first distinguished alumnus award on the occasion of the silver jubilee celebrations of the National Centre for Biological Sciences, India.
