Magdalena Bezanilla

Magdalena Bezanilla is Professor of Biological Sciences and Chair of the Department of Biological Sciences at Dartmouth College, where she also holds the Ernest Everett Just 1907 Professorship and serves as Professor in the Molecular and Cellular Biology Graduate Program. Her research laboratory focuses on understanding the molecular mechanisms that govern plant cell growth and shape determination using advanced cellular and molecular techniques.

Dr. Bezanilla received her B.S. from the University of California, Santa Barbara and her Ph.D. from Johns Hopkins University. Her academic career has established her as a leading researcher in plant cell biology, with particular expertise in cytoskeleton dynamics and membrane trafficking processes.

Her research program investigates how molecules within cells encode geometric information that leads to cell shape determination, with a primary focus on the role of regulators of the cytoskeleton and membrane trafficking. She employs high-resolution live-cell imaging coupled with precise CRISPR-mediated genome editing to study the molecular connections between actin and microtubule cytoskeletons and vesicle trafficking. Her laboratory pioneered the use of moss (Physcomitrella patens) as a model system due to its rapid transgenic capabilities and efficient homologous recombination, which are unique among land plants.

Analysis of Dr. Bezanilla's publication record reveals a strong research trajectory focused on plant cell growth mechanisms, with particular emphasis on tip growth processes, cytoskeleton organization, and cell wall patterning. Her work spans multiple disciplines including plant cell biology, molecular genetics, cytoskeleton dynamics, and cellular imaging, with publications appearing in high-impact journals such as The Plant Cell, Trends in Cell Biology, and Annual Review of Plant Biology.

• Over 50 publications spanning from 2003 to present
• Research contributions to plant cell structure glossaries and terminology
• Development of innovative molecular tools for plant cell research
• Significant contributions to understanding cytoskeleton-membrane interactions

Dr. Bezanilla's laboratory has developed several important research tools including RNA interference (RNAi), quantitative complementation analyses, and rapid quantitative growth assays that have advanced the molecular characterization of plant cell growth. Her work has implications for both fundamental plant biology and potential applications in renewable energy through gene discovery for increased plant biomass.
