Biography

Professor Westrate grew up in West Michigan and earned her B.S. in Biology and B.A. in Chemistry from Hope College in Holland, Michigan. Having always been interested in science, Hope College provided her first introduction to scientific research and she became fascinated by the inner complexities of the cell. The disconnect between textbooks, which at first glance can paint a story that we know everything there is to know about the cell, was in sharp contrast to the narrative in the laboratory settings that highlighted just how much we still did not understand. The ability to design experiments and use the results to begin unpacking the world around us was an immediate hook for her and laid the foundation for the educational choices Professor Westrate made after graduation. In 2008, Professor Westrate joined the Van Andel Research Institute as a graduate student studying the structure and dynamics of mitochondria in cells. In 2012, she graduated with her Ph.D. in Molecular Biology and Genetics and moved to the University of Colorado-Boulder for her post-doctoral fellowship where she began studying the structure and dynamics of another organelle in the cell, the endoplasmic reticulum (or ER for short). Having always wanted to have the opportunity to introduce the next generation of scientists to the world of research, Professor Westrate jumped at the opportunity to join the Chemistry and Biochemistry Department in the fall of 2018 and has been teaching courses in general chemistry and biochemistry while also maintaining a small lab of 2-5 students. When she is not in the classroom or the lab, Professor Westrate enjoys traveling, hiking and playing board games with friends and family.

  • Organelle structure and function
  • Fluorescent microscopy

Research and scholarship

Professor Westrate’s research interests are in the area of organelle biogenesis and structure with a specific focus on how organelle shape dictates important cellular processes. Similar to the way that organs in a body regulate specialized functions, organelles are specialized substructures in the cell that facilitate specialized functions essential for survival. The mitochondria for example are considered powerhouses of the cell and house the protein machinery required to produced energy currency in the form of ATP that the cell can use to run various chemical reactions. The endoplasmic reticulum, or ER, is the largest organelle in the cell and plays essential roles in protein synthesis and trafficking as well as lipid and calcium homeostasis. Despite the relatively simple cartoon structures depicted in a standard biological or biochemical textbook, these organelles have dynamic and complicated structures and are often changing their shape in response to various cellular cues. A current interest in Professor Westrate’s lab is understanding how the structure of the ER alters the diffusion dynamics of proteins found within the ER with a particular focus on how it might regulate the efficiency by which proteins are made, trafficked and exported out of the ER to various cellular locations.
