Biologists Present Research on the Development of Eyes in Flies and Frogs at Sigma Xil Meeting

Mark Deutschlander, assistant professor of biology, and Sarah Evans, a senior biology major, attended the annual meeting and student research conference of Sigma Xi, the scientific research honor society. The meeting was held in Montreal, Quebec, Canada, from Nov. 11-14.

Deutschlander served as the delegate of the Geneva chapter of Sigma Xi, representing researchers from both Hobart and William Smith and the New York State Agricultural Experiment Station. Both scientists presented research posters on the biology of eyes.

In a student competition, Evans received a ribbon of excellence for her poster presentation, titled “Characterization of a Novel Transcription Factor involved in Drosophila Eye Development.” Evans’ work on fly eye development is conducted under the guidance of Kristy Kenyon, assistant professor of biology.

Deutschlander presented the research of Lisa DeLucia ’04. Their poster was titled “Visual Pigment Composition and Violet Photosensitivity in the Pre- and Post-Metamorphic African Clawed Frog, Xenopus laevis.” DeLucia received a Grant-In-Aid from Sigma Xi last year to fund her honors thesis on frog eyes, for which she received high honors. DeLucia was unable to attend the meeting, as she is currently a student at School of Dentistry of the University of Buffalo.

The highlight of the four-day meeting for Evans and Deutschlander was a presentation on sustainable living by plenary speaker, David Suzuki, of the Suzuki Foundation.
