What do nascent multicellular organisms and colloidal particles have in common? Packing matters! Check out our new Nature Physics paper to learn more! Also, be sure to read the fantastic News&Views article on this work by Vernita Gordon!

Our new preprint investigates how coffee-ring-effect produces gradients in cell-density when a drop of liquid culture is dried. These initial conditions have a large impact on the subsequent competition between strains, and can even switch which strain wins. Thus, the coffee-ring effect may ultimately impact evolutionary outcomes.

Dhaivat Mehta was one of the grand award winners at this year’s Georgia Science & Engineering Fair! He has been working with us on his project “Modeling T6ss-Mediated Killing in Microbial Colonies.”

Check out our paper on a different form of active matter, whose activity is not due to mobility, but to death and reproduction! Published this week in Nature Communications, this interdisciplinary paper brought together classic physics, microbiology, ecology and more!

Doominic Robe and Stefan Boettcher, of Emory, and Paolo Sibani, of University of Southern Denmark, and I recently searched for – and found – signatures of ‘record dynamics’ in aging colloidal glasses. The paper was recently published in EPL (arxiv version here).

Cornelia Rosu, then of Paul Russo’s lab in the Georgia Tech Department of Materials Science and Engineering, led an investigation of domed microcylinders in cholesteric liquid crystals.

How can a two component system phase separate if its constituents are densely packed and lack mobility? See the preprint from our collaboration with Will Ratcliff, Brian Hammer, and Sam Brown here to find out!

We are pleased to welcome graduate student David Yanni, as well as undergraduates Colin Brandys, Nathaniel Moore, Jackson Vance, and Shawn Sanderlin to the lab!

Brent Limyanksy is the very first lab alumnus. He graduated from Georgia Tech with a BS in physics, and has left Atlanta for sunny California where he will attend graduate school at UC Santa Cruz. While in the lab, Brent investigated complex interactions at the air-water interface in a series of thorough and creative experiments. We wish him luck in his grad school career!

Our work, in collaboration with Dave Weitz at Harvard and Shaorong Chong at New England Biolabs, on the in vitro assembly of membrane proteins on oil drops was recently published in PNAS.
