内森Ahlgren is interested in understanding how environmental factors and interactions between microbes and viruses shape the evolution, 多样性, and structure of microbial communities. Marine microbial communities are extremely diverse and control globally important cycles in the flow of nutrients and carbon on our planet. A fundamental component to understanding their importance to our planet is knowing what factors control and maintain the 多样性 and structure of these communities.

How the phenotype influences an organism’s function, 以及这如何影响它的生态, is of key importance to understanding the 多样性 of organisms that have evolved. 菲利普·伯格曼的 laboratory studies how phenotype relates to organismal function and ecology, with a particular focus on locomotion in reptiles and amphibians. The lab integrates data from fieldwork, 高速视频, x射线的视频, force plates to understand these relationships at the organismal level, both intraspecifically and in a phylogenetic context.

罗伯特Drewell’s laboratory is investigating the molecular mechanisms of gene regulation during development using genomic and synthetic biology, with computational and mathematical approaches. Much of his lab’s work is focused on using insect model species, including 果蝇 社会性昆虫, to analyze the epigenetic and regulatory networks that control gene expression in the embryo.

Fungi play critical ecological roles as decayers, pathogens, and mutualists. Fungi also represent an independent origin of multicellularity within eukaryotes, including complex forms such as 蘑菇 and puffballs. 大卫Hibbett‘s laboratory uses phylogenetic and phylogenomic approaches, coupled with fieldwork and anatomical and cultural studies, to understand the patterns and mechanisms of morphological and ecological diversification in mushroom-forming fungi.

黛博拉 罗伯逊 lab uses molecular and physiological approaches to understand how marine algae and plants respond to natural and anthropogenic fluxes in nitrogen availability. 目前, members of the 罗伯逊 lab are exploring the cellular mechanisms that allow diatoms to persist during periods of nitrogen deprivation and then rapidly respond to episodic and seasonal increases in nitrate availability. 除了, researchers are developing new DNA transformation vectors and methods for a variety of diatom species.

在开发过程中, 细胞 within multicellular organisms have to “know” when and whether they should divide and what kind of cell they should become. The genes that control these decisions are the same ones that become altered in human tumors. 贾斯汀萨克雷他的研究小组使用果蝇 果蝇 to investigate how these regulatory cascades work, focusing on eye and wing development. He also is using the fly system to search for drugs that inhibit these pathways as potentially novel anti-cancer treatments.
