Brief biography

On a summer afternoon, I wade down a Driftless stream, gripped by tiny muddy fingers, collecting insects to bring back to a row of microscopes in a barn shared by horses and eager elementary school learners. In my research lab, students press in around me as I point out muscle sarcomeres glowing green under a fluorescent microscope; we imagine ways that we could use molecular tools to prevent muscle cells from experiencing the weakness that accompanies aging. While leading a molecular ecology sailing expedition, I help a research student ease a panic attack that gripped her upon losing sight of land and find comfort in this shared adventure. At the onslaught of the COVID pandemic, in a Zoom session with 120 General Biology students sequestered in their dorms, 30 of them with active COVID infections, I stop lecture to create space to share symptoms and fears. These are moments of fulfillment in my 10-year career as a biomedical researcher, professor, and public health leader. 

I've added some descriptions of my teaching and research projects in the hyperlinks below.

In Fall 2022, I will be taking a leave to attend medical school at the University of Wisconsin School of Medicine and Public Health.

Teaching history

After nine years teaching at UWL, my core understanding of teaching and learning hasn’t changed, but the expression of that philosophy has expanded into reaches I didn’t think possible. My own education grounded in the liberal arts has strongly shaped how I approach science education, including how I motivate students. There are many reasons a student chooses to pursue science, but one of the most compelling is the pursuit of science in service to others. Science can be timely, relevant, and captivating, as we’ve seen with COVID, but we rarely teach science through this lens. I build and revise science courses with clear intent to engage students in authentic problems that I hope will fascinate and even obsess them in a drive toward success. Coupled with best practices in science education, such as learning communities, active learning, problem-solving, and guided inquiry, I have witnessed students achieve outcomes I didn’t think 20-year-olds capable of. What I’ve learned is that my role as an instructor is to create curiosity-provoking worlds for students to enter into—as the guide, I describe the scenery, the dangers, and the riddles, and this is what ultimately compels students to learn. I provide the right tools at the right time, demonstrate how to use them effectively, and then get out of the way so that students have the intellectual space they need to plan, pursue, fail… pursue again, and eventually succeed, developing self-confidence and self-efficacy.

Jennifer Klein and Alder Yu, both Biology; Nabamita Dutta, Economics; Alysa Remsburg, Environmental Studies; Tesia Marshik, Psychology; and Adam Driscoll, Sociology & Criminal Justice; co-authored the article "New frontiers in student evaluations of teaching: university efforts to design and test a new instrument for student feedback" in Assessment & Evaluation in Higher Education published on April 5 by Taylor and Francis Online. This article summarizes the efforts put forth by the Ad-Hoc SEI committee with exploring the problematic use of SEIs on campus, selecting and modifying an alternative tool (the soon to be adopted LENS system), and conducting some early findings regarding its efficacy.

Daniel Walgenbach, Cade Armstrong, College of Science & Health and Jacob Kailing, College of Science & Health, all Biochemistry (ASBMB Cert) BS; Alex Steil, Biology (Cell and Molecular Concentration); and Jennifer Klein, Biology, Biology; co-authored the article "The calmodulin redox sensor controls myogenesis" in PLOS ONE published on Sept. 17 by Public Library of Science (PLOS). Muscle aging is accompanied by blunted muscle regeneration in response to injury and disuse. Oxidative stress likely underlies this diminished response, but muscle redox sensors that act in regeneration have not yet been characterized. Students in Molecular Biology Lab (Bio 436) contributed to using the CRISPR-Cas9 gene editing system to introduce a single amino acid substitution M109Q that mimics oxidation of methionine to methionine sulfoxide in one or both alleles of the CALM1 gene, one of three genes encoding the muscle regulatory protein calmodulin, in C2C12 mouse myoblasts. When signaled to undergo myogenesis, mutated myoblasts failed to differentiate into myotubes. Students in Advanced Microscopy (Bio 449/549) found that although early myogenic regulatory factors were present, cells with the CALM1 M109Q mutation in one or both alleles were unable to withdraw from the cell cycle and failed to express late myogenic factors. We have shown that a single oxidative modification to a redox-sensitive muscle regulatory protein can halt myogenesis, suggesting a molecular target for mitigating the impact of oxidative stress in age-related muscle degeneration. Research was funded by the National Institutes of Health (National Institute of Aging). Over 100 UWL students contributed to this publication! Thank you to all of those students who braved the waters of course-embedded research and found success.
