Lars Tomanek is Associate Professor at Cal Poly Biological Sciences Department, College of Sciences and Mathematics. The scientific interest of Professor Lars Tomanek focuses on the changes in levels of protein expression in response to environmental stress. His scientific group applies a proteomic approach (expression proteomics) to address some basic questions in ecology and evolution: How are organisms adapted to their environment? How do they differ in their plasticity to respond to environmental change? How do these differences in protein expression limit the ecological niche an organism can occupy? Which proteins are the weak links, which ones are always working the same no matter which environment the organism is found in? What is the unity in physiological design? What are the underlying mechanisms for the diversity of physiological systems and how do these differences determine the ecological boundaries of species distributions?
