ABOUT

I am a Scientist at École Polytechnique Féraletedérale de Lausanne where I teach and conduct research since December 2019.

Before this I was a research scholar at Princeton University and a postdoctoral fellow at University of Illinois at Urbana-Champaign. I completed my PhD at the University of Wisconsin-Madison in August 2014. Before graduate school I also worked as a developer for Morningstar Inc. where I administered databases containing and processing large amounts of financial data. During graduate school, I also spent time as an intern at 3M Corporate Research Labs where I utilized my background in computation and information sciences for materials and product driven needs of 3M.

My postdoctoral research was supported in part by the NSF Center for Science of Information Postdoctoral Fellowship.

RESEARCH

I am broadly interested in all theoretical aspects of data science; in my work I use tools from {information, learning, coding}-theories, statistics, cryptography, and other areas of applied mathematics. My current research interestes are particularly focused on the followoing topics:

• mathematical models for privacy and secrecy, fundamental limits of privacy-aware information processing systems;
  
• theory of data compression, finite blocklength data compression, universal data compression, private data compression;
  
• secret key generation from common sources of randomness, information-theoretic methods in cryptography;

If you are perspective PhD student interested in coming to EPFL and working with me, please do apply through EDIC and mention my name in your application.

TEACHING

• COM-622: Topics in Information-Theoretic Cryptography Fall 2020, Fall 2021 (EPFL)
  

  This is a theoretical graduate course that will survey the interaction between information theory, cryptography, security, and privacy. This course will mainly focus on questions related to secrecy and information. We will ask very basic theoretical questions like: What is information? What does it mean to keep information secret? How do we model informatoin secrecy mathematically? What kinds of resources (randomness, computation, communication, etc.) are needed to achieve this? Topics covered in the course include perfect secrecy, information-theoretic secret key generation, randomness extraction, information leakage measures like differential privacy, mutual information, as well as some emerging approaches like maximal leakage and perfect privacy.

• EE-205: Signals and Systems Spring 2020, Spring 2021 (EPFL)
  

  The design of advanced systems (such as WiFi, cell phones, drones, airplanes) requires a thorough theoretical underpinning. This is a second year class that teaches one of the most powerful and important pillars: The theory of linear time-invariant (LTI) systems. These systems serve both as models of physical reality (such as the wireless channel) and as engineered systems (such as filters and control strategies). The class covers the following topics: LTI Systems; The Frequency Response of stable LTI Systems; Fourier Techniques for stable LTI Systems (with applications to Communication Systems and Signal Processing); Laplace and Z-Transform Techniques for LTI Systems (with applications to Control Systems).

• ELE-205: Information Signals Spring 2019 (Princeton Universty)
  

  Signals that carry information play a central role in technology and engineering, ranging from sound and images to MRI, communication, radar, multimedia interaction, and robotic control. This course teaches mathematical tools to analyze, manipulate, dissect, and preserve information signals. A major focus of the course is transforms - in particular, the Fourier, Laplace, and z- transforms - which reveal the frequency spectrum of signals and can make them easier to manipulate. We also study sampling, the process of converting a signal from continuous to digital, and which transforms to use depending on the waveform. Additional topics covered include linear time-invariant systems, modulation, quantization, and stability.

• ELE-530: Theory of Detection and Estimation Fall 2018 (Princeton University)
  

  An introduction to the fundamental theoretical principles of signal processing related to detection and estimation. The level of this course is suitable for research students in communications, control, signal processing, and related areas.
