I am a biologist that uses molecular approaches to understand basic cellular processes with a focus on the heat shock response. Our primary model system is the small roundworm, C. elegans, but we also utilize cultured human cell lines to validate and extend our findings.

My primary research focus is the heat shock response. The heat shock response is a universal stress response that is also critical for normal growth and associated with a number of human diseases. The heat shock response activates a protective transcriptional program during sudden temperature increases, but it primarily senses protein misfolding and activates molecular chaperones that assist protein refolding.
The central role of protein folding in the cell explains the requirement for the heat shock response during normal growth, aging and development. Furthermore, the heat shock response is intimately associated with a wide variety of human diseases. For example, many cancers demonstrate strong induction of the heat shock response in the absence of increased temperature. In contrast, activation of the heat shock response appears to be beneficial in many models of neurodegenerative diseases.
We have completed a genome-wide screen to identify new regulators of the heat shock response. Many of these genes were previously associated with neurodegenerative diseases and cancer. Now, our primary focus is to characterize these new regulatory pathways and explore their roles in disease. Our research has revealed that regulation of the heat shock response is customized for each tissue and we are also exploring the molecular basis of this discovery.
