Research Interests

The Thiele laboratory investigates two areas of biology. In one area, we study how Heat Shock Transcription Factor 1 (HSF1) senses the presence of misfolded proteins and other cellular stresses and activates the expression of genes that prevent protein aggregation and maintain cell function and viability. We use genetics, chemical and structural biology, cell biology, mouse models of human disease to solve fundamentally important questions on the role of HSF1 in health and disease. In another area we investigate how organisms acquire and detoxify copper and how these processes are accomplished and regulated by membrane transporters, signaling molecules, transcription factors and novel mechanisms. Our studies focus on the fungal pathogen Cryptococcus neoformans, on mouse models for mammalian copper metabolism, and at the host-pathogen interface in fungal pathogenesis.
