I got my Bachelor's and Master's degrees in mathematics at
the University of Belgrade, former
Yugoslavia, and Ph.D. in mathematical logic at the University of California at Berkeley,
while holding University of California Regents Fellowship. My thesis was
entitled "Fragments of Arithmetic and Lengths of Proofs"; I was
fortunate to have as my Thesis Advisor Professor Jack Silver, one of the
foremost set theorists, and as a Thesis Committee member Professor Manuel
Blum, whose work stimulated my interest in Theoretical Computer Science.
After graduating at Berkeley, I got a tenure track position as an Assistant
Professor at the Carnegie Mellon University, where I taught for 5 years at
the Department of Philosophy and the CMU's Program for Pure and Applied Logic.
I left CMU to start a company, and my startup "Kromos Technology"
employed several of my former CMU students. The company's CEO was Raj Parekh,
former CTO of Sun Microsystems and among our investors and Board members were
former President and COO of AMD Atiq Raza, the
former CEO of Fiberlane, Cerent
and Siara Raj Singh, as well as Redwood Venture
Partners. The company was acquired by Comstellar
Technologies and it is now a part of "Kromos
Telecommunications". I joined the School of Computer
Science and Engineering at UNSW in 2002, where I am teaching
algorithms and data structures. My research interests include sampling theory
and signal processing, applications of mathematical logic to computational
complexity theory, algorithms for embedded systems design as well as
educational use of puzzles for teaching serious problem solving techniques.
