NIEHS Science Days celebrate excellent trainees and mentors

Bernhart, Williams, and Gabor

It may be no coincidence that Fellow of the Year Bernhardt, left, works for Mentor of the Year, Williams, center, who received her award from NTA representative Gabor, right. “The mentors here are taking bright people, who are very knowledgeable, and leading them in a way that enables them to do their best in conducting science,” Abramowitz said of the NIEHS training environment.

Each year, NIEHS researchers gather during the first week of November to share their work, explore collaborations, and celebrate excellence with awards. The NIEHS Science Days event Nov. 5-6 included recognition for the trainee and mentor of the year, as well as the best trainee poster and talk.

“Science Days is, in part, a training exercise — it gives trainees a forum to develop their technique in giving poster and oral presentations,” said Joel Abramowitz, Ph.D., special assistant to the NIEHS scientific director. “No other institute has the breadth of the types of science that we do here, so the trainees have to explain themselves to a broad audience.”

Fellow and mentor of the year

The NIEHS Trainees Assembly (NTA) names a mentor of the year based on nominations from trainees and researchers alike. In 2012, the NIEHS Office of Fellows Career Development (OFCD) began selecting a fellow of the year, awarding travel funds to attend a conference.

Tammy Collins, Ph.D., OFCD director, said the fellow award was created to recognize a trainee with the outstanding qualities necessary for a well-rounded independent research career. A panel of scientists evaluated the nominees and selected Miranda Bernhardt, Ph.D., an Intramural Research Training Award fellow (IRTA) in the Reproductive Medicine Group, headed by Carmen Williams, M.D., Ph.D.

“Miranda has a passion for reproductive biology,” said Williams. “And she’s an intellectual powerhouse.” She cited Bernhardt’s successful demonstration of a novel calcium channel involved in egg fertilization (see related story). Williams also noted Bernhardt’s commitment to service, especially science education, among her qualifications for the prize.

In a fitting surprise, Kristin Gabor, Ph.D., announced that the NTA choice for mentor of the year was Williams. Bernhardt and Williams returned to the podium. “I’ve been able to accomplish so much more than I would have without her leadership and guidance,” Bernhardt said.

Other nominators cited Williams’ commitment to training the next generation of reproductive scientists and clinicians. One noted the possible key to Williams’ success. “She listens to all ideas, no matter how outside the box they are,” the letter read.

Excellent science presentations in talks and posters

Continuing the robust showing of recent years, Science Days featured 92 posters, representing research across all divisions of the institute. Scientists stood by on Nov. 5 to discuss their research with participants.

Organizers planned to recognize the top nine posters and award travel funds to the top five. But when the judges’ scores were tallied, there was a six-way tie for fourth place, and the Division of Intramural Research stepped up and provided all nine winners with cash awards (see text box).

Trainees presented nine of the scientific talks featured in the festival. Mitoki Takaku, Ph.D., won the best oral presentation award. Takaku, a visiting fellow in the Eukaryotic Transcriptional Regulation Group, headed by Paul Wade, Ph.D., discussed the mechanism of chromatin reprogramming by GATA3, a pioneer transcription factor that has been implicated in the progression of breast cancer.

“The science is of a really high quality. We have a magnificent group of people here doing important work, and it’s really important to acknowledge it,” Abramowitz said afterward.
