"I was drawn to Goucher to work in a liberal arts environment where I could maintain a research program with students and support students in the classroom and research lab."
Assistant ProfessorBiological Sciences, Biochemistry and Molecular Biology
Jenny Lenkowski is an Assistant Professor of Biological Sciences at Goucher College in Baltimore, Maryland. After receiving her bachelor’s degree, Dr. Lenkowski taught in China then worked as a research technician at Tufts Medical School before returning to graduate school. She completed her doctorate in biology in 2010 at Tufts University Graduate School of Arts and Sciences. Prior to her arrival at Goucher in 2013, she completed post-doctoral research at the University of Michigan exploring how the vertebrate retina regenerates using zebrafish as a model organism. At Goucher College, Dr. Lenkowski’s research focuses on the TGFβ signaling pathway and its potential role in the regulation of neural development and regeneration in zebrafish. She also teaches several courses in the biology and biochemistry and molecular biology programs that include introductory biology, cell biology, development biology, and neurobiology.
Research, Scholarship, Creative Work in Progress
The Lenkowski Lab research focuses on how the zebrafish retina develops and how it regenerates following intense light injury that destroys photoreceptor cells. Historically, researchers had observed that teleost fish could regenerate destroyed areas of the neural retina. While hypothesized, it was not until the mid-2000s that Müller glial cells were proven to act as a tissue specific adult stem cell in this process and studies of the regulation of the regenerative process could truly begin with more modern approaches. In particular, we are particularly interested in the role of conserved molecular pathways in regulating the cell cycle in Müller glial cells. Research has shown that proper regulation of TGFβ signaling during retinal regeneration is critical in the zebrafish. The Lenkowski Lab is building on previous research to explore how TGFβ signaling regulates the cell cycle and differentiation in neural development and regeneration. Because zebrafish have the capacity to regenerate their photoreceptors and mammals do not, these studies inform comparisons among vertebrates to identify gene targets for human regenerative medicine. Undergraduate students are an integral part of this research during the school year and during Goucher College’s Summer Science Research Program (see * in presentations and posters for Goucher student contributions).
