Taylor Allen teaches in the area of physiology, the study of how molecules, cells, organs, and organisms function

I teach three courses, each of which seeks to develop students’ mastery of physiological concepts, understanding of the experimental evidence supporting these concepts, and ability to design meaningful experiments.

Animal Physiology (Biol 312), which is given in the fall, examines the function of the body from molecular to oganismal levels and considers topics ranging from the communication between cells to the adaptations of animals to pregnancy or to extreme environments.

Cell Physiology (Biol 313), taught in the spring, concerns the vibrant activity of cells and focuses on the intracellular machinery and signaling pathways supporting this activity, with examples drawn from developmental biology, immunology, and cancer biology.

Cell Physiology Research (Biol 314), the third course, seeks to introduce students to the methods of research, from the formulation of an experiment to the presentation of findings and conclusions. Students work in pairs on a problem selected in consultation with the teacher and gain proficiency in one or more methods drawn from recombinant DNA technology, genetics, and cell biology.

Contraction of Muscle and Its Regulation

Before reading about my research interests, here's an experiment to do on yourself: hold a tennis ball in your hand and determine how many times you can squeeze the ball.

If you are like most people, you'll probably manage a total of about 100 squeezes, much less than the number of contractions your heart probably will tirelessly make in your lifetime (on average, about 2,500,000,000 beats!).

Research in my laboratory addresses how skeletal and cardiac muscles turn force production on and off, as well as how individual muscles gain unique contractile characteristics, such as the heart's ability to contract repeatedly for a seemingly indefinite period of time. At the simplest level, muscle has two components: a motor capable of transforming chemical energy (ATP) into mechanical work (force generation and shortening of muscle cells), and a calcium-sensitive switch for the motor. The four proteins forming the switch have been known for 25 years; however, the way they work is largely a mystery. Mutations in the switch proteins can cause lethal heart disease in humans and improper muscle development in the nematode Caenorhabditis elegans and the fly Drosophila melanogaster.

Such knowledge, if it were available, would guide pharmacologists and physicians in the treatment of muscular diseases, e.g., the weakened heart of an elderly patient, for whom stronger, perhaps more rapid heart beats might be desired.

To clarify how the switch mechanistically work, we are engineering mutations in genes that code for proteins in the switch, transferring the mutant genes into C. elegans, and then examining the consequences of these mutations to muscle function in C. elegans. By systematically mutating the genes, we shall be able to map particular functions of the switch (e.g., controlling the speed of contraction) to discrete protein surfaces. Such knowledge will enable drug designers to produce drugs that most effectively treat various muscular disorders.


  • Maureen Peters Presents with Students

    April 14, 2014

    Several fourth-year biology students attended the Ohio Physiology Society Annual Meeting at the Northeast Ohio Medical University this Fall with Associate Professor of Biology Maureen Peters. These included members of her lab, Nelson (Trip) Freeburg, Phoebe Hammer, Sam McCright and a member of Associate Professor of Biology Taylor Allen's lab, Helen Rich. The students presented posters describing their respective research projects, while Peters presented a talk entitled "As the Worm Turns: Understanding How an Intestinal Calcium Wave Elicits a Motor Program." Several students received recognition for their work. Phoebe Hammer '14 was awarded a Poster Presentation Prize. Nelson (Trip) Freeburg and Sam McCright both won the Peter K. Lauf Travel award to fund expenses associated with attending the Experimental Biology annual meeting in San Diego, CA in the spring.


Community Partnership Focuses on Accessibility in Science

August 7, 2017
Oberlin Associate Professor of Biology Taylor Allen and Peter Ogbuji, executive director of the Harrison Cultural Community Center, cosponsored a camp to make science more creative and accessible to children in Lorain County.
