# Alexander Bershadsky

Alexander D. Bershadsky is a Russian-Israeli cell biologist who studies the actin cytoskeleton and cell motility. His research has contributed to the understanding of cytoskeletal dynamics and mechanotransduction.

## Early life and education

Bershadsky was educated in Russia, graduating from Moscow State University. He earned his Ph.D. from the Cancer Research Centre of the Russian Academy of Medical Sciences under the supervision of Prof. Juri Vasiliev. In 1988, he co-authored Cytoskeleton with Vasiliev, a textbook that systematically addressed the structure and dynamics of the cytoskeleton.

## Career

After earning his doctorate, Bershadsky relocated to Israel in 1992 and joined the Weizmann Institute of Science, where he progressed from scientist to full professor. His career includes several visiting professorships at institutions such as the Curie Institute (Paris, France, 2005), the Marine Biological Laboratory (Woods Hole, Massachusetts, USA, 2007), and the National University of Singapore (Queenstown, Singapore, 2008–2010).
As of February 2025, he serves as a Senior Principal Research Scientist at the Mechanobiology Institute at the National University of Singapore and holds the Joseph Moss Professorial Chair of Biomedical Research at the Weizmann Institute. Also as of February 2025, Bershadsky serves on the editorial board of the international journal Cytoskeleton (formerly known as Cell Motility and the Cytoskeleton).

## Research and contributions

Cell motility and mechanotransduction: Bershadsky's work explores how cells use mechanical forces to regulate adhesion, migration, and intracellular trafficking. He demonstrated that focal adhesions function as mechanosensors, converting mechanical stimuli into biochemical signals.
Cytoskeletal dynamics: Bershadsky's studies have advanced the understanding of actin filament assembly and organization. In particular, his research on the role of formins in actin polymerization and the interplay between actin and microtubules has provided insights into cell morphology and movement.
Mechanosensitivity and adhesion complexes: Bershadsky's research has shown that the physical forces generated by, or acting upon, a cell can affect the formation and regulation of adhesion complexes. These forces, in turn, affect key cellular processes such as migration, polarization, and tissue organization.
Advanced imaging techniques: Bershadsky's laboratory employs advanced microscopy methods, including structured illumination microscopy (SIM), to capture dynamic processes in cells in real time. These techniques have improved visualization of cytoskeletal organization and focal adhesion dynamics.

## Personal life

Alexander D. Bershadsky is married to Svetlana Greenberg, and they have a daughter named Natasha Bershadsky, along with two grandchildren.
