Mark F. Jacquin, Ph.D., research professor of neurology at the medical school, was cited for distinguished contributions to somatosensory research in rodents, including the molecular mechanisms for the development of circuitry in the trigeminal system.

Jonathan B. Losos, Ph.D., professor of biology in Arts & Sciences, was cited for distinguished contributions to the field of animal evolution and for studies on morphology and adaptive differentiation in Anolis lizards.

And Philip A. Osdoby, Ph.D., professor of biology, was cited for distinguished contributions to the field of bone osteoclast development and physiology and for studies on cell-matrix interactions in bone.

The three are among 376 people this year awarded the honor by AAAS because of their scientifically or socially distinguished efforts to advance science or its applications. New fellows will be presented with an official certificate and a gold and blue (representing science and engineering, respectively) rosette pin at the Fellows Forum during the 2006 AAAS Annual Meeting Feb. 18 in St. Louis.

This year's AAAS fellows were announced in the Oct. 28 issue of Science.

The tradition of AAAS fellows began in 1874. Currently, members can be considered for the rank of fellow if nominated by the Steering Groups of the association's 24 sections, or by any three fellows who are current AAAS members (so long as two of the three sponsors are not affiliated with the nominee's institution), or by the AAAS chief executive officer.

Each Steering Group then reviews the nominations of individuals within its respective section. A final list is forwarded to the AAAS Council, the policymaking body of the association, which votes on the aggregate list.
