Nick a tissue, and the lesson begins. Signals flash. Adhesions brace. Neighbors confer. The sheet closes as one. That’s Rothenberg’s lab, biology unfolding in real time. For Dr. Katheryn Rothenberg, motion is both subject and method. She studies how cells migrate together, how tissues heal, how forces carry meaning. In her classroom, models spring to life, and in her lab, biology is constantly in motion: force, feedback, response.
An Assistant Professor of Biology at the University of Iowa, she investigates collective cell migration, how mechanical and biochemical cues sync up to shape and repair tissue. Her work spans Drosophila embryos, human cell lines, time-lapse imaging, and questions about Rap1 GTPase signaling that ripple through wound repair and metastasis.
Ask her how she sees herself, and she resists separating her duties. “I really do strongly identify as a researcher-educator,” she says. In a tenure-track world that pushes priorities into silos, she insists on integration, building a lab that pursues discovery and opens doors for students to find their footing in science.
Motion brought her here. Trained as a biomedical engineer, she gravitated toward mechanobiology, where physics meets life’s mess. Biology, she says with a laugh, “is weird… it doesn’t always follow the rules.” That’s the appeal, using precise tools from math and physics to chase questions that refuse to sit still.
Her focus sharpened on collective migration, a phenomenon you can literally watch. Fluorescence shows cells organizing at a wound edge, myosin gathering like a cast at curtain-up, adhesions strengthening as neighbors pull, push, and signal across a tissue sheet. “Seeing is believing, and understanding,” she says. So, her teaching leans hard on visualizations and hands-on modules, where students can tweak a parameter and watch the system respond.
In the lab, the choreography is intentional. A laser makes a tiny cut, a signal to begin. Then the cast responds. Cells gather at the edge, shifting and tightening like dancers finding their marks. The scene is captured frame by frame, each movement tracked and translated into a story of motion. Picture a Drosophila embryo: a thin, living sheet of cells where invisible forces suddenly become visible. You can see tension build. You can watch the edges draw together. Beneath it all, a deeper question pulses: how do cells, faced with chaos, know how to act as one?
Mentorship is the other current that drives her work. As an undergraduate, Dr. Rothenberg’s mentors gave her room to explore with a safety net, honest feedback, consistent check-ins, and a lab culture where communication outranked ego. She models the same. Good mentoring, she says, starts with helping people clarify what they value and how they work best, then building a community that supports it. That includes setting boundaries: reminding trainees to go home before 6:30, resisting the sprint mentality in a marathon field. These choices shift the atmosphere toward care, not just output; toward a lab that learns to talk, not just pipette.
That ethos carries into the classroom. When a textbook diagram falls flat, she brings in movies, models, and interactive “what-if” explorations. Students see transporters open, actin flows build, cells migrate. They don’t just learn, they experience. The result is agency: learners who can connect a fluorescence movie to a patient’s wound, or a simulation to a future experiment. “Light-bulb moments,” she says.
Community matters, too. Dr. Rothenberg arrived at Anatomy Connected and felt the energy, posters buzzing, disciplines mixing, ideas forming across silos. She hadn’t always seen herself as “an anatomist,” but that changed. The association’s wide tent welcomed her in. If your work touches the human body, you belong. Motion across boundaries is the point.
In the end, Katheryn’s work is a study in dual momentum, cells moving together to heal, and a teacher-mentor moving students toward ownership. Research and education, not in competition, but in sync. Mechanics and meaning. The work moves, and so do we.
