Hood Lab: "Degeneration of the Non-Recombining Regions in the Mating-Type Chromosomes of the Anther-Smut Fungi"
Fontanillas E, Hood ME, Badouin H Petit E, Barbe V, Gouzy J, de Vienne DM, Aguileta G, Poulain J, Wincker P, Chen Z, Toh SS, Cuomo CA, Perlin MH, Gladieux P, Giraud T. Degeneration of the non-recombining regions in the mating-type chromosomes of the anther-smut fungi. Molecular Biology and Evolution (2015) 32: 928-943.
Genes for mating compatibility often reside in regions of suppression recombination and cytological differentiation within the chromosome pair.

Clotfelter Lab: "Guanine-Based Structural Coloration as an Indicator of Oxidative Stress in a Cichlid Fish"
Matthew D. Cahn ‘13, Alexandria C. Brown and Ethan D. Clotfelter. Guanine-based structural coloration as an indicator of oxidative stress in a cichlid fish. Journal of Experimental Zoology, in press.
"We used a novel approach to measure structural coloration in a fish and found that structural coloration can be condition-dependent and indicative of environmental stress."

Purdy Lab: “The Acetate Switch of an Intestinal Pathogen Disrupts Insulin Signaling and Lipid Metabolism"
Saiyu Hang, Alexandra E. Purdy, William P. Robins, Zhipeng Wang, Manabendra Mandal, Sarah Chang, John J. Mekalanos, and Paula I. Watnick. The acetate switch of an intestinal pathogen disrupts insulin signaling and lipid metabolism. Cell Host & Microbe. November 12, 2014.
Vibrio cholerae unexpectedly manipulates host metabolism and virulence by controlling acetate levels in the GI tract via the CrbRS signal transduction system.
