Sujata Vasudev Bhat, born in Ankola, on 16-06-1940 in the south Indian state of Karnataka to Nagesh Shanbhag and Ramabai, did her college studies at Karnataka University from where she graduated in chemistry in 1961 and followed it up with a master's degree in 1963 with distinction and 1st rank. Subsequently, she enrolled for doctoral studies under the guidance of S. C. Bhattacharyya, National Chemical Laboratory Pune and secured the degree of Doctor of Philosophy in 1967 from the Savitribai Phule Pune University, Pune and moved for her post-doctoral studies at the laboratory of professor Werner Herz and completed her post-doctoral studies at Florida State University, USA. On her return to India in1972 she joined the Basic Research Centre, of Hoechst Pharmaceuticals, Mulund as Senior Scientist and Head of Natural Products Division and contributed by finding many bioactive molecules from Indian Medicinal plants. In 1984 she moved to Indian Institute of Technology, Bombay as a member of faculty at the departments of Chemistry & Biomedical Engineering, where she set up her research group and served as the professor with Organic Chemistry & Biomaterial specialization till superannuating in 2002 from academic duties as the professor of the department. Subsequently she has set up Advanced Research Laboratory (ARL) in Vaze College with assistance from her student Kedar Vaze and Kelkar education trust.[2] She serves as a Researcher and Advisor to Industries.

Bhat was married to Vasudev and the couple has one son Ashish and daughter in law Supriya.


Sujata V. Bhat is A woman achiever, who is a skilled and committed researcher and excellent teacher, known to have been involved in researches on terpenoids and alkaloids and have contributed to the structural elucidation of a number of them. It was during these investigations, she discovered new skeletal types in Sesqui- and diterpenoids. Based on her researches, she proposed correctly the structure and absolute Stereochemistry of Forskolin, the molecule currently well-known for Adenylate cyclase enzyme stimulation and various biological activities.
