Seeking Laboratory Technologist (Wet Lab Core Facility) at the Mechanobiology Institute, NUS
The Mechanobiology Institute (MBI), National University of Singapore (NUS), is seeking to recruit a Laboratory Technologist (Wet Lab Core Facility).
Great to host Saanjbati Adhikari, Reviews Editor at Development, at MBI
Saanjbati gave a lovely seminar to the MBI community on publishing in Development and her personal journey in academic publishing. It was also a huge privilege to share my own research journey through the Transitions in Development series; click in for the link to the article!
Ronen Zaidel-Bar
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
- How do specific cytoskeletal proteins contribute to the organization and function of cell adhesion and actomyosin structures?
- How are signals processed within the “adhesome” and “contractome” to arrive at the appropriate cytoskeletal arrangement for a given cell state?
- 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.
