Don’t panic, keep calm. This is me, this is an old painting, and these are les frites.

I am a machine learning scientist at Amazon Development Centre India. Previously, I was working with Rodolphe Sepulchre as a postdoctoral fellow at the University of Liège and as a visiting research associate at the University of Cambridge. I was also a research fellow (aspirant) of the Belgian National Fund for Scientific Research (F.R.S-FNRS).

I graduated with a PhD degree in 2014 from the department of electrical engineering and computer science (Institute Montefiore) at the University of Liège, Belgium. The thesis was completed under the guidance of Rodolphe Sepulchre and Francis Bach. Prior to this, I graduated from IIT Bombay, India in 2010 with a dual degree – Bachelors and Masters degrees – from the department of electrical engineering. And before that, I was leading a normal relaxed life in Bhubaneswar, Odisha and attending +2 science classes in BJB college.

Nowadays, chances of finding me around this place and particularly in this building are high.


My interests are on nonlinear optimization and machine learning. I look at exploiting the two fundamental structures of least-squares and symmetry in optimization problems. A specific focus has been on developing efficient numerical algorithms for large-scale problems with rank and orthogonality constraints. I am also involved in the development and promotion of the Matlab toolbox Manopt for optimization on manifolds.

Manopt 2.0 is out now. Example
