Fraden Group

Overview

We study a broad range of topics in Soft Matter utilizing a variety of methods spanning experiment, theory, and simulation. Current research thrusts are in active matter, non-linear chemical dynamics & chemical networks, chemomechanics & soft robotics, protein crystallization, microfluidics and DNA origami. As our research interests lie at the intersection of physics, chemistry, biology, materials science and engineering, we are interdisciplinary, but as these projects are large and challenging, we collaborate in multi-investigator projects.

Postdoctoral position in experimental Active Matter

 

We have an opening for a postdoc to join the Fradenlab at Brandeis University, Waltham, MA USA and collaborate with experimentalists Zvonimir Dogic and Guillaume Duclos and theorists Michael Hagan and Aparna Baskaran, to understand the striking phenomena and dramatic new physical behaviors observed in confined active nematics. The experimental system consists of extensile bundles of microtubules that consume ATP and generate flow. We will use 3D printers and photolithographic methods to manufacture a variety of confined geometries and use fluorescence microscopy on confined nematics to measure the velocity, director and concentration fields as a function of container size and geometry, as well as microscopic parameters such as ATP, tubulin and kinesin concentration. We’ll employ second-harmonic generation light microscopy to probe the alignment of the microtubules. A number of newly developed variants of this system allows control over boundary and initial conditions, network architecture and coupling of the force producing kinesin motors to the microtubules.

 

The ideal candidate would have experience in soft matter and biophysical experimentation, light microscopy, image processing and in working with purified biological components. The position is available immediately.

 

Applications with CV, research statement and the names of three references should be sent to fraden@brandeis.edu.
