Abstract
My lab currently has a major and a minor interest:

The major interest is, currently, the quantitative analysis of complex systems at the protein level via mass spectrometry. This includes virus molecular structure, the effects of infection processes on all proteins of the infected cell, and mechanisms of oncogenesis.

My minor interest (currently) is the molecular dynamics of nucleic acid polymerization using, as a model, the simplest known translocating nucleic acid polymerase and the only known polymerase that can translocate independently on single-stranded nucleic acid (a non-rigid polymer).
