About

I am mainly interested in improving health, well-being, and education using technology. My main field of research is Machine Learning but I am also a part of the cryptography group where we work on the Private AI project in which we try to build AI tools that preserve privacy. This is significant in domains such as health and education in which privacy is of great significant. I am working on developing technologies to help people with behavioural change. Here, the goal is to help people with their diets, sleeping habbits, managing stress and more. Other subjects that I have been working on include measuring gait and balance, machine learning theory, machine teaching, and debugging machine learning.

Homomorphic Encryption

Established: March 27, 2016

Homomorphic Encryption Homomorphic Encryption (HE) refers to a special type of encryption technique that allows for computations to be done on encrypted data, without requiring access to a secret (decryption) key. The results of the computations remain encrypted, and can be revealed only by the owner of the secret key.   Motivation While traditional encryption schemes can be used to privately outsource data storage to the cloud, the data cannot be used for computations without…

Secure Multi-Party Computation

Established: June 10, 2011

It is often the case that mutually distrustful parties need to perform a joint computation but cannot afford to reveal their inputs to each other. This can occur, for example, during auctions, data mining, voting, negotiations and business analytics. Secure multi-party computation (MPC) allows a set of parties, each with a private input, to securely and jointly perform any computation over their inputs.

Gait and Balance App

October 2016

The Gait and Balance app uses the Kinect for Windows (V2) to measure different metrics related to gait and balance. This can be used, for example, for assessing risk of fall among older adults or for tracking the progress of different treatments.
