Research
The goal of my program is to investigate stressor maladaptation mechanisms such as they occur in several diseases. Our approach takes advantage of the way nature has evolved to control such stressors, and that is by a unique usage of the chaperome, referred here as the epichaperome. The epichaperome, which we discovered, is structurally, dynamically and functionally distinct from the housekeeping chaperome, and my lab has pioneered an approach to take advantage of such features. By using innovative methods, we develop small molecule chemical toolsets specifically targeted to the epichaperome; these act as “sensors” of the epichaperome, and in turn, of the chronic stressor-associated proteome-wide malfunctions. By the use of these unique toolsets we aim to understand, diagnose and treat cellular processes associated with chronic stressors. We address multiple mechanistic and biochemical questions less amenable to approaches that treat the chaperome as monolithic entity (i.e. the classical biochemical and genetic tools). We investigate in endogenous systems, both at the cellular and the organismal level, the inherent proteome changes and mechanisms that lead to disease, i.e. we can understand. By sensing disease states through the chemical toolsets, we go beyond investigation; we identify, measure and quantify, i.e. we can diagnose. By attacking the epichaperome specifically, we perturb the disease-causing proteome, and in turn revert or slow the disease phenotype, i.e. we can treat.
