Hi, I am Amrita Roy Chowdhury. I am a CRA/CCC Computing Innovation postdoctoral fellow at the University of California, San Diego and my advisor is Prof. Kamalika Chaudhuri. I recently completed my PhD from the University of Wisconsin-Madison under Prof. Somesh Jha. Before that, I obtained my Bachelor of Engineering in Computer Science from the Indian Institute of Engineering Science and Technology, Shibpur where I was awarded the President of India Gold Medal.


My research explores the synergy between differential privacy and cryptography through novel algorithms that expose the rich interconnections between the two areas, both in theory and practice.

Here is the link to my CV.

Miscellaneous

5 completely unsolicited facts about me --

  • If Ι were to describe myself and my work in a single sentence, I would say "I am indistinguishable from an anthropomorphic squirrel, who has humbugged her way into the Bluε Stockings Sociεty, for a PPT adversary."

  • I have an inordinate and perfervid predilection for circumlocutory and highfalutin verbiage. QED.

  • I would be well-disposed to having a dispassionate disquisition on whether to pet a Portuguese man o' war or a Porpita porpita at 3:07 am in the morning.

  • I would feature in the Forbes Billionaires List if the unit of currency were Scoville heat units consumed.

  • I would tell you all about my thoughts on "Why we should care for the Encephalartos woodii?", but I'm afraid I have exhausted my privacy budget.
