Graduate student Andrew DeBenedictis has just published his paper “Competition of lattice and basis for alignment of nematic liquid crystals” in Physical Review E. Featuring other coauthors Candy Anquetil-Deck, Doug Cleaver, David Emerson, Mathew Wolak, James Adler, and Tim Atherton, the paper represents a collaboration among physicists and mathematicians here at Tufts and at Sheffield […]
Grad student Chris Burke has just published his paper “The role of curvature anisotropy in the ordering of spheres on an ellipsoid” in the journal Soft Matter along with co-authors Badel Mbanga, Zengyi Wei, Patrick Spicer, and Tim Atherton. This paper focuses on geometric frustration: spheres tend to form orderly hexagonal packings, but they can’t do this on a curved surface, so there must be defects […]
In this paper, we study the evolution of defects on a deforming, curved interface endowed with liquid crystalline order.
Two nematic shells brought in contact coalesce in order to reduce their interfacial tension. We study the defect textures as the combined shell shape evolves. Using large scale computer simulations, we resolve the director field and […]
We’re delighted to announce that our new paper, published in collaboration with Cristian Staii’s lab is now available online at Physical Review E. We’re particularly excited to congratulate undergraduate researchers Dan Rizzo (the first author!) and Matt Wiens on their first peer reviewed paper—well done!

The paper combines simulations, experiments and theory to understand how a patterned surface can be used to control the alignment of a nematic liquid crystal. […]
Chris Burke celebrates his first journal article published today in the Journal of the Optical Society of America B. The preprint version of the article is also to be found on the ArXiV.
This work was part of a collaborative project with Rolfe Petschek and Joe Lesnefsky at Case Western Reserve University.
Our wonderful collaborators in the Kaplan Group in the Biomedical Engineering Department at Tufts have just published a new paper which our group PI Tim Atherton is a co-author on. The work presents the work of graduate student Amy Hopkins et al. who has been looking at new soft materials—hydrogels made with Silk—as a […]
We’re delighted to announce that our new paper has been published as a Rapid Communication in Physical Review E. This paper is the first fruit of our collaboration with James Adler of the Mathematics department here at Tufts. James is an expert in numerical methods, which we’ve brought to bear on a difficult […]
A new paper that we’ve contributed to has just been published in Applied Physics Letters, describing how specially patterned surfaces prepared by Melik Demirel’s Biointerface Engineering group at Penn State can guide the direction of neuronal growth. This work was principally performed by Cristian Staii‘s experimental biophysics group at Tufts. Our contribution to the […]
Our latest paper has just been published in the journal Physical Review E. This is a collaboration with Doug Cleaver of Sheffield Hallam University in the United Kingdom and Candy Anquetil-Deck of Das Karlsruher Institut für Technologie in Germany.
This paper is also available as a preprint on the ArXiV.
