The Revelations of Devout and Learn'd آنان که محیط فضل وآداب شدند
Who rose before us, and as Prohphets burn'd, در جمع کمال شمع اصحاب شدند
Are all but Stories, which, awoke from Sleep ره زین شب تاریک نبردند برون
They told their comrades, and to Sleep return'd گفتند فسانه ای و در خواب شدند

I am interested in understanding learning and inference in living organisms and machines and for doing so, mainly use ideas from statistical mechanics and information theory.
I was born in Tehran in 1981, went to Alborz High School, and studied at Sharif University and SISSA. After that, I went to the Gatsby Unit, UCL, as a senior research fellow and then to Nordita, the Nordic Institute for Theoretical Physics.
