The group develops unconventional model systems to reveal hitherto unrecognized aspects of cellular organization. We are especially interested in adaptive cellular traits based on high-order protein assemblies and organelles. The group fuels discovery with biochemical purification, mass spectrometry and comparative genomics. Many of the proteins we study are restricted to a group of related species. However, upon investigation they are frequently found to function through connections with ancient and conserved components of the cell. Thus, our work is predisposed to revealing fundamental principles of cellular organization, while also uncovering new protein activities. Approaching cell biology through the lens of evolution further creates opportunities to identify new problems or approach long-standing problems from new directions.
As the global population grows to a projected 9.8 billion in 2050, overall food demand is on course to increase by more than 50 percent. Technological innovations that raise food production efficiency and productivity without expanding agricultural land are a key to meeting this challenge in a sustainable manner1. In soil ecology, multicellular fungi specialize to break down plant litter, and play a pivotal role in decomposition and soil nutrient cycling. We are working to harness this power under controlled conditions to convert plant food production waste into added value nutritional products. This work leverages our 15 years of experience with the genetics, cell biology and physiology of multicellular fungi. 1 World Resource InstituteSelected publications
