Greetings! I am Nikita Kalinin, a PhD student in the Institute of Science and Technology Austria (ISTA), fortunate to be under the supervision of Christoph Lampert. I am exploring the intriguing field of Differential Privacy as part of my recent academic journey. I am particularly interested in the following topics:

  • Matrix Factorization Mechanism in Differential Privacy
  • Differentially Private Model Training
  • Differentially Private Parameter Estimation
