Abigail Jensen

Abigail Jensen is an Associate Professor in the Department of Biology at the University of Massachusetts Amherst, within the College of Natural Sciences. She serves as Graduate Program Director and Principal Investigator of a research lab focused on vertebrate retinal development and disease. Her laboratory investigates the molecular and cellular mechanisms of photoreceptor outer segment morphogenesis and renewal, using zebrafish as a primary model organism.

Education:

• B.A., University of California, San Diego, 1988
• Ph.D., University of Wisconsin, Madison, 1992
• Postdoctoral Training: University College London (1992–1996), University of Oregon (1996–2002)

Her research centers on understanding how photoreceptor outer segments—highly modified cilia responsible for light detection—are formed, maintained, and renewed throughout life. A major focus is on the continuous renewal process involving proximal growth and distal shedding of outer segments, which is critical for long-term photoreceptor viability. Her lab developed innovative tools such as the Tg(hsp70:HA-mCherryTM) transgenic zebrafish and Tet-On inducible systems to study the kinetics and regulation of outer segment renewal in vivo.

The recent publications reflect a strong trend in molecular and cellular mechanisms of photoreceptor development, particularly involving polarity complexes (e.g., Crumbs complex), FERM domain proteins (e.g., Mosaic eyes, Yurt), and transgenic tools for temporal control of gene expression. These studies bridge developmental biology, neuroscience, and cell biology, with implications for inherited retinal degenerations such as retinitis pigmentosa and macular degeneration.

Dr. Jensen leads a research team that includes a senior research associate, postdoctoral fellow, research assistants, and undergraduate students. She mentors early-career scientists and maintains an active research program, as evidenced by publications up to 2012. While no formal scientific awards are listed in the provided text, her contributions to retinal biology are significant, particularly in elucidating the role of key proteins in photoreceptor structure and function.

She has been involved in securing research tools and plasmids for the community, with requests directed to her lab. Her work has implications for developing therapies to prolong vision in retinal degenerative diseases by maintaining outer segment integrity.
