*Quantum Information Theory*on a solid mathematical and physical foundation. This has not only yielded rich dividends for the foundations of quantum theory, but has also provided insights into questions in quantum optics, condensed matter physics, and more recently, black-hole physics.

My current research interests fall into three broad categories:

(i) Studying decoherence in physical systems and evolving schemes to tackle such decoherence
efficiently via *Quantum error correction*

(ii) Understanding the interplay between uncertainty and complementarity, with implications for
*quantum cryptography* and *quantum foundations*.

(iii) Quantum information as a tool to explore fundamental questions in other areas of theoretical physics.
