Biophysics Seminar: Andrew Gordus, Johns Hopkins University| Untangling the web of behaviors used in spider orb-weaving
Mon, Dec 6, 2021, 12:30 pm12:30 pm

Many innate behaviors are the result of multiple sensorimotor programs that are dynamically coordinated to produce higher-order behaviors such as courtship or architecture. Extended phenotypes such as architecture are especially useful for ethological study because the structure itself is a physical record of behavioral intent. A particularly…

Biophysics Seminar: Jeff Gore, Massachusetts Institute of Technology| Emergent phases of ecological diversity and dynamics mapped in microcosms
Mon, Nov 15, 2021, 12:30 pm12:30 pm

Natural ecological communities display striking features, such as high biodiversity and a wide range of dynamics, that have been difficult to explain in a unified framework. Using experimental bacterial microcosms, we have performed the first direct test of recent theory predicting that simple aggregate parameters…

Biophysics Seminar: Alison Sweeney, Yale University| The Physical Design of Optimum Solar Resource Utilization in Giant Clams
Mon, Nov 1, 2021, 12:30 pm12:30 pm

Photosynthesis presents a paradox of solar energy: the maximum quantum efficiency of photosystem II likely surpasses that of any engineered system, but in environments with high solar flux, photosynthetic organisms are famously wasteful and resource inefficient. For example, even in agricultural systems bred for maximum resource efficiency such…

Biophysics Seminar: Jeanne Stachowiak|The University of Texas at Austin|Disordered protein networks as synergistic drivers of membrane traffic
Mon, Oct 25, 2021, 12:30 pm12:30 pm

Membrane curvature is required for many cellular processes, from assembly of highly curved trafficking vesicles to extension of needle-like filopodia. Consequently, defects in membrane curvature play a role in most human diseases, including altered recycling of receptors in cancer and diabetes, targeting of filopodia by pathogens, and hijacking…

Biophysics Seminar: Andrej Kosmrlj| Princeton University: Pattern formation in biological systems via mechanical instabilities and phase separation
Mon, Sep 20, 2021, 12:15 pm12:15 pm

Pattern formation is ubiquitous in biological systems. While pattern formations are often associated with Turing-like reaction-diffusion systems, biology also exploits many other mechanisms such as mechanical instabilities and phase separation. In this talk, I will discuss how mechanical instabilities cause the wrinkling of bacterial biofilms…

Biophysics Seminar: Justin Kinney, Cold Spring Harbor Laboratory| Massively parallel assays, machine learning, and the biophysics of gene regulation| Zoom
Mon, May 10, 2021, 12:15 pm12:15 pm

Gene expression in all organisms is controlled by short DNA and RNA sequences called cis-regulatory elements (CREs). Proteins in the cellular milieu bind to nucleic acid sequences present within CREs, interact with one another, and thus form macromolecular complexes that modulate the expression of nearby genes. My lab uses…

Biophysics Seminar: Rosalind Allen, Edinburgh University| Geometry of bacterial growth and division| Zoom
Mon, May 3, 2021, 12:15 pm12:15 pm

The rod-shaped bacterium Escherichia coli proliferates by a process of elongation, followed by constriction at its centre to create new cell poles. Despite intense study, some apparently simple questions about the dynamics of growth and division in E. coli continue to be debated - these include whether the cell length increases exponentially or…

Biophysics Seminar: Julia M. Yeomans, University of Oxford| Active nematic physics in cell layers and tissues| Zoom
Mon, Apr 26, 2021, 12:15 pm12:15 pm

Active materials such as bacteria, molecular motors and eukaryotic cells continuously transform chemical energy taken from their surroundings to mechanical work. Dense active matter shows mesoscale turbulence, the emergence of chaotic flow structures characterised by high vorticity and self-propelled topological defects. I shall describe the…

Mon, Apr 19, 2021, 4:00 pm4:00 pm

Living systems need to remember information about their environment in order to take decisions that ultimately ensure survival. But storing information about past experiences costs energy, while only a fraction of the vast amount of information available can be useful to the living system. An intelligent memory formation strategy should take…

Biophysics Seminar: Nikta Fakhri, MIT |Broken symmetries in living matter | Zoom
Mon, Apr 12, 2021, 12:00 pm12:00 pm

Active processes in living systems create a novel class of non-equilibrium material composed of many interacting parts that individually consume energy and collectively generate motion or mechanical stress. In this talk, I will discuss experimental tools and conceptual frameworks we develop to uncover laws governing order, phase transitions and…

Mon, Mar 29, 2021, 12:15 pm12:15 pm

Perception, attention and working memory are fundamental cognitive functions, which are based on parallel processing in many brain areas. Neuronal oscillations at sub-second timescales and their phase correlations a.k.a. phase-synchronization are putative mechanisms for the coordination of neuronal processing and…

Mon, Mar 22, 2021, 12:15 pm12:15 pm

One of the characteristic features of many marine dinoflagellates is their bioluminescence, which lights up nighttime breaking waves or seawater sliced
by a ship’s prow. While the internal biochemistry of light production by these microorganisms is well established, the manner by which fluid shear or mechanical
forces trigger…

Biophysics Seminar: Kinneret Keren, Technion, Israel| Topological defects in the nematic order of actin fibers as organization centers of Hydra morphogenesis| Zoom
Mon, Mar 1, 2021, 12:15 pm12:15 pm

Morphogenesis, the emergence of functional form in a developing organism, is one of the most remarkable examples of pattern formation in nature. Despite substantial progress, we still do not understand the organizational principles underlying the convergence of this process, across scales, to form viable organisms under variable conditions. We…

Mon, Feb 22, 2021, 12:15 pm12:15 pm

Simple organisms manage to thrive in complex environments. Remembering information about the environment is key to take decisions. Physarum polycephalum excels as a giant unicellular eukaryote being even able to solve optimisation problems despite the lack of a nervous system. Here, we follow experimentally the organism's response to a nutrient…

Mon, Feb 1, 2021, 12:15 pm12:15 pm

An animal eye is only as efficient as the organism’s behavioral constraints demand it to be. Efficient coding has been a successful organizational principle in vision, and to make a more general theory, behavioral, mechanistic, and even evolutionary constraints need to be added to this framework. In our work, we use a mix of known computational…

Biophysics Seminar: Kranthi Kiran Mandadapu, University of California Berkeley: On the role of motility and glassy dynamics in growth of bacterial monolayers into the third dimension| Zoom
Mon, Nov 23, 2020, 12:15 pm12:15 pm

Many mature bacterial colonies and biofilms are complex three-dimensional (3D) structures. A key step in their developmental program is a transition from a two-dimensional (2D) monolayer into a 3D architecture. Despite the importance of controlling the growth of microbial colonies and biofilms in a variety of medical and industrial settings,…
