Three U.Va. Professors Named As Fellows By AAAS

November 1, 2005 -- Three University of Virginia professors have been named fellows by the American Association for the Advancement of Science (AAAS). Election as a fellow is an honor bestowed upon AAAS members by their peers.

The three faculty members are Carla B. Green, an associate professor of biology; Joyce Libby Hamlin, a professor of biochemistry and molecular genetics; and John L. Hudson, a professor of chemical engineering.

Green was selected for her innovative contributions to understanding the molecular mechanisms underlying circadian rythmicity, particularly in the retina. Green has long contributed to new understandings of the biological clock and how mammals are affected by light cycles. The work in her lab has implications for treating sleeping disorders, jet lag and ways for adjusting the schedules of shift workers.

Hamlin was named for her contributions to understanding the location and characteristics of DNA replication origins, which are the sites on the chromosomes where replication begins. There are more than 50,000 of these sites in the human genome. Her laboratory not only identified the first such site, but most recently has developed a method for isolating all of them. Hamlin is trying to understand the processes that sometimes lead to errors in replication, which can result in growth advantages for cells that could over-replicate as tumors. Understanding these processes could eventually lead to therapies for inhibiting the growth of cancers.

Hudson was named for his contributions to the understanding and engineering of complex chemical and electrochemical reacting systems. His work focuses on processes involving large numbers of interacting chemical reaction sites. The work has been shown to be important in understanding the onset of corrosion in metals such as stainless steel and it has potential applications in describing the rhythms of circadian oscillations and epilepsy.

“This is exciting news,” said Dr. R. Ariel Gomez, vice president for research and graduate studies, of the naming of these U.Va. fellows. “This is a very nice recognition of the wonderful work that our faculty are doing. They are also outstanding individuals.”

This year 376 members of AAAS have been named fellows in honor of their scientifically or socially distinguished efforts to advance science or its applications. Their names were announced in the Oct. 28, 2005 issue of the journal Science, which is published by AAAS. The new fellows will be presented with a certificate and a rosette pin next February at the annual meeting of the association in St. Louis.

The tradition of AAAS fellows began in 1874 and is regarded as a prestigious distinction among scientists. AAAS is the world’s largest general scientific society and includes 262 affiliated societies and academies of science serving 10 million individuals.
