Research Interests

Research Program Overview

Changes in cell shape and adhesion are two fundamental hallmarks of the differentiation of eucaryotic cells. To better understand the mechanistic basis of these processes we are studying their roles in the life cycle of the budding yeast, Saccharomyces cerevisiae. Three main projects are presently underway in the laboratory:

  • Analyses of a novel paxillin homolog and Rho GTPase signaling modulator, Pxl1p
  • Studies of the functions, traffic, and inhibition of fungal adhesins
  • Functional genomics of fungal control of lipid and membrane homeostasis

Undergraduate Research Opportunities

My research program seeks to determine the molecular mechanisms that enable cells to dynamically alter their shape and surface adhesion properties in response to specific developmental or environmental cues. Understanding the roles played by genes involved in cell shape change and adhesion is generally important to developing our knowledge of eucaryotic cell functions and cell-cell interactions in processes such as neurite outgrowth and gastrulation, for example.

The primary organism we use in our studies is the baker's yeast Saccharomyces cerevisiae, as yeast cells offer the dual advantage of powerful genetic approaches and equally powerful cell biological approaches to understanding cell signaling and cytoskeletal remodelling and microbial adhesion mechanisms. Our projects generally involve a mixture of molecular and cell biological techniques such as plasmid cloning, PCR, cell fractionation and protein purification, and fluorescence or electron microscopy. We also make use genetic analyses whenever possible.

Restrictions: It is highly preferable that students be prepared to dedicate a minimum of two semesters to their research experience.


BIO 327: Genetics and Cell Biology II

Taught Spring semesters (co-taught with Dr. Russell of Biology)

3 credits

Cell structure, molecular biology of eukaryotic cells, cytoskeletal organization and function, cell division cycle, membrane structure and function, cell-cell interactions, cell differentiation and regulation.

BIO 435 Genetics Laboratory

Taught Fall semesters (co-taught with Dr. Belote of Biology)

3 credits

The general purpose of this course is to allow students to gain experience in conducting analysis using genetic methods. In this course we will use two of the organisms that have been of fundamental importance in the development of our understanding of genetic principles. These are: the fruit fly, Drosophila melanogaster and baker's yeast, Saccharomyces cerevisiae. All students will carry out a series of experiments investigating various aspects of genetic analysis using the research organisms listed above. Three lab reports and three quizzes will be required.

BIO 462/662 Molecular Genetics

Taught Fall semesters (co-taught with co-taught with Drs. Raina and Belote)
