Biography

Dorairajan Balasubramanian was born on 28 August 1939^[8] in the South Indian state of Tamil Nadu.^[3][4] He graduated in Chemistry (BSc) from Madras University in 1957 and secured his master's degree (MSc) in Chemistry with first rank^[11] in 1959 from Rajasthan University, Pilani.^[2][3][4][5] He moved to USA in 1960 for researching for his doctoral studies and completed it in 1965 to obtain PhD^[5] in biophysical chemistry from Columbia University.^[2][3][4][8] He continued in USA for his post doctoral research as a Jane Coffin Childs Fund Fellow at the University of Minnesota Medical School till 1966.^{[2][3][4][5][8]}

Balasubramanian returned to India in 1966 and joined the Indian Institute of Technology, Kanpur^[3][5] as a lecturer where he rose in ranks over the years to become an assistant professor and a professor.^[2][4][8] In 1977, he was appointed as the professor and dean of the School of Chemistry at the University of Hyderabad^[5][9] where he worked till 1982^[8] when he took up the post of the deputy director of the Centre for Cellular and Molecular Biology.^[2][3][8] He retired from the institution as its director^[5] in 1998 and moved to L. V. Prasad Eye Institute where he is the director of research of Prof. Brien Holden Eye Research Centre.^{[2][3][4][5][8][9]} He also serves as the visiting professor at the University of New South Wales, Sydney and as the adjunct professor of Birla Institute of Technology and Science, Pilani, India.^[2][3][4]

Balasubramanian is married to Shakti who is associated with E TV as a producer and the couple has two daughters.^[3][4] The elder daughter, Katyayani is a research analyst and the younger one, Akhila works as a public health professional.^[3][4] The family lives in Hyderabad.^[3][5]

Positions

Balasubramanian is a visiting scientist at the National Eye Institute, Bethesda and is a senior Fellow of ophthalmology at the University of Melbourne.^[2] He is the chairman of the Task Force on Stem Cell Research set up by the Department of Biotechnology of the Government of India.^[5] He is a former president of the Indian Academy of Sciences (2007-2010)^[4][8] and is the incumbent the chairman of the Biotechnology Advisory Council of the Government of Andhra Pradesh.^[3] A former secretary general of The World Academy of Sciences,^[3][4] he has served as the project coordinator of Translational Centre in Eye Diseases of Champalimaud Foundation (C-TRACER) and the Affordable Healthcare Project of the Wellcome Trust for finding solutions for the use of scaffolds for cultivating stem cells.^[8] He is a former member of the International Human Rights Network of Academies and Scholarly Societies,^[12] the International Basic Sciences Panel^[13] of UNESCO and the International Chapter Affiliate Committee of the Association for Research in Vision and Ophthalmology (ARVO),^[14] USA.^[8] He has also served as an editorial board member of several international journals.^[4][5]

Balasubramanian started his research activities in 1965 focusing on the structure and functions of proteins and polypeptides^[15] and worked on the thermodynamic analysis of their stability.^[1][5][8] The focus of his research changed in 1984/85 when he started to work on ocular science and concentrated on crystallins of eye lens and their function as an agent in keeping the lens transparent.^[16] His research revealed how cataract is caused when crystallins are damaged photochemically, thereby leading to diminished lenticular transparency.^[1] He argued that the oxidative stress on the lens induces covalent chemical changes in the constituent molecules^[3] and these changes lead to cataract.^[1][4][5][8] He researched further on the subject to find out that, by supplementing antioxidants and cytoprotective substances, the progression of cataract can be slowed down.^[4] These findings are known to have introduced a prophylactic approach to addressing the issue of cataract, which is reported to be the causal factor for 47.9 percent^[17] of the blindness in the world.^[1] Further, he attempted to identify the cataractostatic agents and proposed the benefits of tea polyphenols,^[18] Ginko Biloba^[19] and Withania somnifera extracts.^[20] These substances contained antioxidants and cytoprotective compounds which slow down the progression of oxidative cataract and this was verified during experiments in animals.^[1]

Advanced vision loss from Glaucoma.

After the turn of the century, Balasubramanian and his colleagues started working on inherited eye diseases^[8] and their molecular genetics.^[4] The group carried out research on diseases such as congenital glaucoma^[5][21] with a sampling set of over 400 families and this has helped in revealing 15 mutations in the gene CYP1B1, with mutation R368H being the most common one.^[4][21] The research has also recorded the genotype-phenotype correlations and the structural changes occur in mutated protein^[4][21] and these findings have assisted in clinical prediction of the disease and in early therapeutic intervention to avert blindness.^[1]

Balasubramanian is now working on stem cell biology and its use in restoring lost vision.^[22] He and his group have been successful in isolating the adult stem cells found in the limbus, around the cornea, and culturing them on human amniotic membrane.^[8] These cultured stem cells were, later, used to produce corneal epithelia that can be stitched on to human eye. Clinical tests on 200 patients who lost eyesight due to chemical or fire burns returned significantly good results with vision restoration to 20/20 levels,^[4] with or without subsequent corneal grafts or transplantation.^[1] These tests are reported to be the largest successful human trial of adult stem cell therapy in the world.^[1][4]

Balasubramanian has published 6 books^[3] of which two books,^[3] one on chemistry and the other in biotechnology, are prescribed text books for academic studies.^[1][4][23] He is credited with over 450 articles,^[3][4] published in peer reviewed national and international journals^[2][24] and Microsoft Academic Search, an online repository of scientific articles, has listed 52 of them.^[25] He has presented more than 170 scientific papers^[1][3][4][5] and has contributed in popularizing science by writing columns in leading newspapers such as The Hindu and The Times of India since 1980.^{[3][4][23][26]} On the academic front, he has assisted 16 doctoral students in their PhD studies.^[5] His efforts are also reported behind the establishment of a vaccine unit at the Centre for Cellular and Molecular Biology and in designing a quality improvement program for the Sericulture Laboratory of the state government.^[4]
