Primary area of research interest is computational complexity theory.
Currently I am working on quantum circuit complexity. I am specifically interested in investigating the power of low depth quantum circuits.
Other areas of interest are information theory, cryptography and information security. Outside of computer science, I like combinatorics and algebra (no linear algebra or geometry please).
I always believed that computer science is about systematically analysing a problem and so it ought to be used by any one dealing with any kind of computation. Lately, we are seeing application of computer science, specially complexity theory, which is about analysing the hardness of a problem, in various fields like bio-computing, economics, management, chemistry etc. I am quite excited about such applications of Computer Science to diverse fields.
My Erdos number is 4.
