While my research work is entirely theoretical,
I keep in mind that physics is fundamentally an experimental endeavor,
hence my abiding interest in quantum measurement theory. I've also
done work in global climate models, soliton theory, nuclear theory, density
functional theory of atoms and molecules, quarkgluon jet phenomenology and nonperturbative
quantum field theory. Currently I am most interested in creating a theory of discrete
space and time based on simple graphs and causal sets.
