Biophysics and Interdisciplinary

Bio-Physics Seminar:"Biomedical Spectroscopic Imaging with Scattered Light"

Location: 
Danciger B building, Seminar room
Wed, 25/12/2019 - 10:00 to 11:30

Lecturer: Prof. L. Perelman (Harvard)
Abstract:
Optical spectroscopy emerged as a valuable tool to study live biological tissue at various scales and
detect early disease in the human body. While fluorescence and Raman spectra are sensitive to
molecular properties of tissue, light scattering spectra, originating from the extracellular matrix,
subcellular structures, and other tissue inhomogeneities, carry information about tissue microscopic and
macroscopic organization. In this talk we will discuss how scattered light can be used for noninvasive

Biophysics Seminar: "Cell Circuits for tissue homeostasis and fibrosis"

Location: 
Danciger B building, Seminar room
Thu, 16/05/2019 - 14:00 to 15:30

Lecturer: Miri Lavi, Weizmann Institute


Abstract:

Tissue processes involve communication between several cell types by means of diverse secreted factors and cell contact signals. This communication allows tissues to maintain homeostasis of cell-type ratios and to respond properly to perturbations such as injury and inflammation. In my talk, I will discuss principles of cell circuits in homeostasis and away from homeostasis as in tissue repair.

Biophysics Seminar: "Directionality and spatial expansion"

Location: 
Danciger B building, Seminar room
Thu, 11/04/2019 - 14:00 to 15:30

Lecturer: Guy Bunin


Abstract:

The dynamics of some systems are directional, meaning that the state of a system can be characterized by a function that increases in time. This includes, for example, the growth of entropy in physical systems, or the growth of fitness in certain formulations of Darwinian evolution. Yet even when directionality holds, it might be sensitive to perturbations, such as external driving of physical systems, or interactions in evolutionary dynamics.

"Biological Physics Seminar: Naturally optimal Scheduling of cellular self- replication"

Location: 
Danciger B building, Seminar room
Tue, 24/03/2015 - 14:00 to 15:30

Lecturer: Dr. Rami Pugatch
Affiliation: Simons Center for Systems Biology,
School of Natural Sciences, Institute for Advanced Study,
Princeton
Abstract:
A bacterial cell is a complex self-replicating
chemical factory. Like other factories it
contains a set of processing units that
convert raw material to useful end-products
in finite time while burning free energy
(cost). Proper function of the factory
requires a schedule, which in a cellular
context is a distributed autonomous

Biological Physics Seminar : "Anomalous Diffusion on the Surface of Mammalian Cells"

Location: 
Danciger B building, Seminar room
Thu, 07/06/2018 - 14:00 to 15:30

Lecturer: Diego Krapf, Department of Electrical and Computer Engineering and School of Biomedical Engineering, Colorado State University, Fort Collins, CO, USA
Abstract:
Tracking individual proteins on the surface of live mammalian cells reveals complex dynamics
involving anomalous diffusion and clustering into nanoscale domains. Theoretical models
indicate that anomalous diffusion can be caused by vastly different processes. By performing
time series and ensemble analysis of extensive single-molecule tracking in combination with
