NIEHS celebrates achievements at annual Science Day
By Heather Franco
NIEHS celebrated the research programs conducted in its intramural and extramural divisions during the 11th annual NIEHS Science Day Nov. 7-8, as scientists gathered to present their research discoveries in poster and oral presentations. The event culminated with the presentation of awards for outstanding poster and oral presentations, and the prestigious Mentor of the Year and Fellow of the Year awards (see related story).
According to organizer Joel Abramowitz, Ph.D., special assistant to the scientific director, the event was a great success. “Everyone was overwhelmed by the science conducted by the trainees at NIEHS,” he told the audience. “Congratulations to everyone!”
Oral presentations highlight diverse areas of research
Science Day opened with a talk by National Toxicology Program (NTP) molecular toxicologist Scott Auerbach, Ph.D., of the Biomolecular Screening Branch. He discussed how bioinformatics can be used to assess the changes that various chemicals have on an organ system and how identifying these changes can help in the identification of the mechanisms involved in the development of disorders, such as cancer.
Jack Taylor, M.D., Ph.D., head of the Molecular and Genetic Epidemiology Group within the Division of Intramural Research (DIR), presented his work on the role of methylation in the development of breast cancer using the NIEHS Sister Study cohort. His group found that changes in methylation status were associated with age, suggesting that epigenetic changes that occur during the aging process may influence an individual’s susceptibility to cancer.
Kimberly McAllister, Ph.D., from the Susceptibility and Population Health Branch of the Division of Extramural Research and Training (DERT), highlighted work from NIEHS grantees exploring gene-environment interactions and their impact on human health. The program focuses on developing methods to explore these interactions, as well as conducting workshops and lecture series to highlight the field.
Continuing the tradition that began at last year’s Science Day, former NIEHS trainee Mohamed Trebak, Ph.D., now at the SUNY College of Nanoscale Science and Engineering, concluded the oral presentations by describing his recent work examining the role that calcium signaling plays in endothelial cell function in the blood vessels. His group has found novel roles for the STIM1, Orai1, and TRPC channels in regulating endothelial cell permeability.
Awardees recognized for their outstanding research and mentoring
The NIEHS Trainees Assembly (NTA) presented two awards, highlighting the excellent research and training received by the trainees at NIEHS. Kymberly Gowdy, Ph.D., of the NTA, presented the Mentor of the Year Award to Dale Sandler, Ph.D., Epidemiology Branch chief and head of the Chronic Disease Epidemiology Group within DIR, for her “excellence and commitment to research, the epidemiology branch, and training.” The 2nd Annual Fellow of the Year Award was presented to Steven Roberts, Ph.D., from the Chromosome Stability Group, who was acknowledged by senior associate scientist Dmitry Gordenin, Ph.D., as being in the “top tier of postdocs that I have mentored.”
This year, the number of Outstanding Poster Presentation Awards was increased to nine, with winners representing multiple labs within DIR and the NIEHS Office of Clinical Research (see text box). The Outstanding Oral Presentation Award was presented to Sabrina Robertson, Ph.D., from the Developmental Neurobiology Group in DIR. Her presentation, “Developmental Origins of Central Norepinephrine Neuron Diversity,” described the identification and manipulation of different subtypes of norepinephrine neurons, which may have implications for the response of these neurons in diseases and to environmental stimuli.
(Heather Franco, Ph.D., is an Intramural Research Training Award (IRTA) postdoctoral fellow in the NIEHS Reproductive Developmental Biology Group of the Laboratory of Reproductive and Developmental Toxicology.)
