I was born in Mumbai, Maharashtra near the Kabootar Khana in Dadar.
My mother, Manak Hari Paranjape was a professor of French and my father, Hari Krishna Paranjape was an economics professor; both of them achieved significant distinction in their fields. My father is no more and my mother lives in Pune.
I have a sister, Jyotsna Paranjape who lives in the south of England with her husband Desmond Chaffey and her son William Siddharth Chaffey. She has a doctorate in economics but teaches in a primary school.
I am married to Sudeshna Sinha who is a faculty member at IISER Mohali in the Department of Physical Sciences. We have one daughter, Shruti Paranjape who was born in the BARC hospital in Mumbai. Shruti is currently in IISER Pune.
Sudeshna’s father is no more. Her mother, Ratna Sinha, has administered and taught in a number of schools in West Bengal. She currently lives in Kolkata.
In other words, we are (willy-nilly) a family of students and teachers!
I grew up in New Delhi, first on the campus of the Indian Institute of Public Administration and then in the residential areas just south of India Gate.
After completing my school leaving certificate from the Sardar Patel Vidyalaya, I joined the Indian Institute of Technology, Kanpur for a five-year integrated master’s programme in Mathematics.
Upon graduation, I joined the School of Mathematics, TIFR and completed my doctorate from there. I learned most of my mathematics there and continue to interact with people there.
Twelve years after joining TIFR, we moved to Bangalore. I was deputed to the TIFR Centre (now it is the Centre for Applicable Mathematics) for a year after which I joined the Stat-Math Unit of the Indian Statistical Institute, Bangalore Centre.
A year later, we were in Chennai, at the Institute of Mathematical Sciences.
After thirteen years there we have taken up a two-year lien to be at the Indian Institute of Science, Education and Research, Mohali which is currently in Chandigarh.
In addition to these places, I have spent significant time at some institutions abroad.
A post-doctoral visit to the University of Paris VII (which was then in Jussieu) was combined with a visit to the University of Paris-Sud at Orsay. I also visited these institutes later.
For half a year I was at the Max-Planck Institute for Mathematics which was then in Beuel, Bonn.
I taught and learned Mathematics at the Dept. of Math., Univ. of Chicago for a year. In the summer of that year, there was a special programme at the Dept. of Math., Univ. of Utah of which I was a part.
Sudeshna and I visited the Dept. of Math., Univ. of Essen in the year before Shruti was born; the university was later merged with the University of Duisberg.
I was an associate of the International Centre for Theoretical Physics (which also has a mathematics research group) and visited this institute a couple of times in this capacity.
Over the last ten years or so, I have visited the Dept. of Math., Caltech quite often.
