Visiting Faculty

Currently Visting

6-12 Nov 2018
Office: T-Lab, Level 5

Research Areas

Cell-cell and cell-matrix adhesion, Regulation of actomyosin contractility and dynamics, C. elegans development, mechanics and molecular mechanisms of morphogenesis

Research Interests

  1. How do specific cytoskeletal proteins contribute to the organization and function of cell adhesion and actomyosin structures?
  2. How are signals processed within the “adhesome” and “contractome” to arrive at the appropriate cytoskeletal arrangement for a given cell state?
  3. How do adhesion sites and the cytoskeleton sense and respond to external mechanical forces?

Biography

Dr Zaidel-Bar obtained his Ph.D. working with Prof Benny Geiger (Weizmann Institute of Science) on the role of force in regulating cell-matrix adhesions. Their work first focused on single proteins and evolved to encompass the entire adhesome network. In his Postdoctoral training with Prof Jeff Hardin (University of Wisconsin – Madison) Dr Zaidel-Bar switched from studying cells in culture to employing the genetic model organism C. elegans for the study of cell-cell adhesions during development. Dr Zaidel-Bar was attracted to Singapore by the opening of MBI and was awarded the Singapore National Research Foundation Fellowship for promising young investigators.

In a study published in Molecular Biology of the Cell led by Celestine Ho at the Mechanobiology Institute, NUS, researchers discover that HIF-1α-activation in SASP is a defining feature of the SASP induced by diverse stressors, acting independently of micronuclei generation and cGAS/STING activation.
