__Yash__vanth Kondi

Welcome!
I completed my PhD at Northeastern in 2022, under the supervision of abhi shelat (find my thesis here). I received my Bachelor's and Master's degrees from the International Institute of Information Technology, Bangalore (IIITB) in 2017, where I was advised by Ashish Choudhury. I was also supervised by Arpita Patra at the Indian Institute of Science (IISc). I spent summer 2020 (and part-time Fall 2020) interning with the crypto group at Novi Research, where I was hosted by Valeria Nikolaenko. I visited Claudio Orlandi at the Aarhus Crypto Group in summer 2019. Preprints
