Lois Weisman serves as the Sarah Winans Newman Collegiate Professor in the Life Sciences, Research Professor at the University of Michigan Life Science Institute, and Professor in the Department of Cell & Developmental Biology at the University of Michigan Medical School. Her laboratory operates within the Life Sciences Institute at the University of Michigan in Ann Arbor, Michigan, where she leads research bridging fundamental cellular mechanisms with disease pathology.
Dr. Weisman earned her A.B. in Chemistry from Rutgers University and her Ph.D. in Biochemistry from the University of California-Berkeley. Her academic trajectory established her as a leading researcher in cellular processes with direct implications for human disease, particularly through her work on phosphoinositide signaling and organelle transport mechanisms.
Her research program investigates two interconnected areas: the PI3,5P2 signaling pathway's role in neurodegeneration and the mechanisms of myosin V-based organelle transport. Her lab discovered that even minor defects in PI3,5P2 signaling cause profound neurodegeneration, and they're exploring whether therapeutic upregulation of this pathway could mitigate disease. Simultaneously, they study how organelles move to precise locations during cell division and differentiation, with defects in these processes linked to neurological diseases and developmental disorders. The lab employs yeast, cultured neurons, and mammalian cell lines to uncover essential cellular mechanisms using biochemical, genetic, and imaging approaches.
Analysis of Dr. Weisman's recent publications reveals consistent focus on membrane trafficking pathways, phosphoinositide metabolism, and myosin motor function. Her work demonstrates how fundamental discoveries in model organisms translate to understanding human disease mechanisms, particularly in neurodegeneration, with significant contributions to elucidating how lipid signaling pathways regulate cellular homeostasis.
Dr. Weisman's scientific excellence has been recognized through prestigious awards:
- National Science Foundation Early Career Development Award (1996-2000)
- American Heart Established Investigator Award (2001-2004)
- Elected Fellow, American Association for the Advancement of Science (2012)
- Induction into the Douglass Society (2013)
- Elected Fellow, American Society for Cell Biology (2022)
As an educator, Dr. Weisman mentors graduate students through the University of Michigan Cellular & Molecular Biology Graduate Program and Neuroscience Graduate Program. Her laboratory includes five current graduate students, two undergraduate researchers, and multiple research investigators. She serves on the Editorial Board of the Journal of Cell Biology and has trained numerous scientists who have established independent research careers. Her lab maintains strong collaborative relationships with other research groups at the Life Sciences Institute.
The Weisman Lab operates as an interdisciplinary research environment combining biochemistry, molecular biology, cell biology, and genetics approaches. Current research focuses on understanding the regulation of phosphoinositide signaling cascades and myosin V cargo transport mechanisms, with the ultimate goal of developing novel therapeutic strategies for neurodegenerative diseases and cancer. The lab actively investigates how defects in these fundamental processes contribute to disease pathogenesis, maintaining strong translational potential for their basic science discoveries.
