This blog is about science and my life as a physicist. I hold a (full) professorship at the Universidade Federal do Rio Grande do Norte, in Natal, Brazil. Until 2010, I held an associate professorship at the Universidade Federal de Alagoas, Maceió.

I obtained my B.A. in physics at Oxford University in 1992 and my  Ph.D. in physics with Professor H. Eugene Stanley at Boston University in 1997.   In the 1980s, I also spent a year studying physics at American College  in Madurai, India, after finishing high school at the North Carolina School of Science and Mathematics (NCSSM), a (publicly funded) boarding school (“residential school”) in Durham, NC, USA.

I was born in the city of Madras (later renamed Chennai) in India, but have lived in Brazil since childhood.   I am a naturalized citizen of Brazil.

Separately from my scientific activities, I maintain an Instagram page about yoga, meditation, healthy eating etc.:

  1. Hi! Don’t know if you remember me, but we shared an office at Boston University as grad students. Hope you’re well, please get in touch if you come to Boston. I like the blog.

  2. I would like to know about the 2-d ising model. I tried to understand M. L. Grasser’s idea (Amer. J. of Physics 38, 1033, 1970) of counting the loops etc. – but to no avail. Also the Grassmann number method for solving this problem. Where can I get an easily understandable detailed version of the two?

    • I believe that my blog contains one of the most easily understandable expositions of both the Grassmann method as well as the loop counting method. There are also books by McCoy, by Baxter, as well as standard stat mech textbooks. It takes some time for beginners to understand some of the concepts, so you should persevere and work slowly, step by step. Good luck!
