Post-doc position in fluid mechanics/physics of the atmosphere/gravity waves 
in LOPS, Plouzané, France

France Energies Marines and LOPS are looking for a young researcher to contribute 
to the improvement of the representation of the Marine Atmospheric Boundary Layer 
and turbulent fluxes in atmospheric models by developing and testing a 
parameterization of the impact of sea sprays (https://en.france-energies-marines.org/content/download/33834/23177/file/200908_PostDoc_CASSIOWPE_SeaSpray.pdf). 
The requested qualifications include a PhD in atmospheric science, wave or 
mechanical physics, or equivalent, and a good understanding of the physics of the 
atmospheric boundary layer and fine-scale processes. 

The projects aim at studying the kinetics of self-assembly of copolymer materials 
and at investigating the rheology of dense polymer melts and composites via computer 
simulations of highly coarse-grained models. Candidates are expected to hold a PhD 
degree in Physics, Chemistry, or Engineering, have experience with molecular
simulations of coarse-grained polymer models or self-consistent field theory, and have 
very good communication skills in English. Experience in high-performance computing 
(using e.g., HOOMD) is desirable.

Deadline for application will be September 15, 2020. Later applications may be considered as long as the position remains unfilled.

Openings: Two Theory/Computation Postdoctoral Researchers in Self-Limited Assembly (SLA), UMass Amherst and Brandeis University(1) Computational Soft Matter (Computational modeling of SLA pathways)(2) Theoretical Soft Matter (Theoretical mechanisms and theory-directed design of SLA)
We seek two postdocs to join a multidisciplinary effort connected to the NSF funded Brandeis Bioinspired Soft Materials research center (Ben Rogers, Seth Fraden, Mike Hagan, and Greg Grason), with a primary goal to elucidate the mechanisms of their assembly into self-limiting architectures using theory, computer simulation and experimental study of geometrically programmed “building blocks”.  For additional information on the scientific scope of the “Self-Limiting Assemblies” (SLA) project, see below.  
We are specifically seeking two postdoctoral positions in theory and computation, one at UMass Amherst hosted in the Grason group, and one at Brandeis University in the Hagan group.  Each position will work closely with both Grason and Hagan, as well as experimental groups (Rogers and Fraden), to develop and test controlled SLA systems.

1) Computational modeling of SLA pathways. Location: Brandeis University Qualifications: Experience in computational physics, including molecular dynamics, Monte Carlo, enhanced sampling, data-driven approaches, and/or implementation of large-scale parallelized/GPU-enabled simulations. Tasks: Simulate assembly of finite-sized architectures using molecular dynamics and Monte Carlo approaches. Primary supervisor: Mike Hagan (Brandeis).
2) Theoretical mechanisms and theory-directed design of SLA. Location: UMass Amherst Qualifications: Experience in soft-matter theory, discrete geometry, and computational physics. Applicants are sought with interests in fields such as soft matter, thermodynamics, and materials science. Tasks: Develop geometrical principles to design new SLA ‘’building blocks ». Develop theoretical models of emergent behavior of geometrically frustrated assembly. Primary supervisor: Greg Grason (UMass: Amherst).Both positions offer ample opportunities for your professional development including participating in exciting cutting-edge science, gaining mentoring experience, and initiating your own research directions.  Women and minority candidates are encouraged to apply. UMass Amherst and Brandeis University are Affirmative Action/Equal Opportunity employers.
Start Date: As soon as September 2020. 
Submit applications to both grason@mail.pse.umass.edu and hagan@brandeis.edu specify which position(s) you are applying for. Please include a CV, a list of references, and a brief description of your previous research.

MRSEC collaboration on “Self Limiting Assemblies”:
The SLA collaborative team (Rogers, Fraden, Hagan and Fraden) will develop a versatile class of DNA-origami building blocks to elucidate the fundamental physical principles for engineering components that self-assemble into large, but finite-size, superstructures. The self-assembly of size-controlled architectures is prevalent in living systems. The adaptive functions of biological materials, including viral shells, cytoskeletal filaments, and photonic nanostructures of bird feathers arise from the regulated finite size of self-assembled architectures. In contrast, most inorganic materials form unlimited structures like crystals. In this project, we will advance two complementary paradigms for bottom-up assembly of size-controlled architectures.  One uses curvature programmed building blocks that assemble into self-closing structures (e.g. tubules and capsules). The other advances a new paradigm of geometrically-frustrated assembly, in which ill-fitting blocks accumulate stresses that grow with assembly and limit their thermodynamic size.
This collaborative research addresses many fundamental questions in self-assembly: How do shapes, interactions, and flexibilities of building blocks control the assembly size? How can self-limiting assembly be adapted to distinct morphologies, like ropes, fibers, sheets or shells? Are there fundamental or practical limits to the sizes of controllably assembled structures? By answering these questions and more, we aim to develop engineering principles to create size-controlled architectures with high yield, with the structural control currently only possible via “top down” fabrication techniques (e.g. 3D printing and lithographic fabrication).

Postdoctoral Associate in Microfluidics and Soft-Materials Research

Brandeis University Bioinspired Soft Materials MRSEC, Waltham, MA, USA

We seek a postdoc to join the Brandeis Bioinspired Soft Materials MRSEC, a multidisciplinary, tightly integrated team, to design and fabricate new microfluidic devices. The focus will be on controlling protein crystallization for drug discovery applications and engaging in basic research in active matter of purified biological systems and self-assembly of DNA origami. The position will be integrated into a team of students, postdocs and faculty who work together across groups and disciplines to achieve our goals.

Responsibilities include training new students in the manufacture and operation of microfluidic devices in our cleanroom and supervising a summer course, taught in conjunction with graduate students. This position offers ample opportunities for professional development including participation in exciting cutting-edge science, gaining mentoring experience, and the potential for initiating new research.

Experience, attributes, and skills sought:

·       PhD in mechanical engineering with a diverse background in microfabrication and microfluidics.

·       Creative scientist with a track record of quality publications.

·       Automation, instrument design and construction, opto-mechanics.

·       Fabrication, including computer-aided design (CAD), CNC, laser cutting, and 3D printing.

·       Mentoring.

·       Interdisciplinary knowledge and skills bridging engineering to soft matter.

·       Work experience in cleanrooms, advanced imaging facilities, and laboratory settings.

·       Team player with outstanding leadership, communication and presentation skills.
