Posters In The Pacific
Pacifichem's student poster competition attracted 2,000 hopeful chemistry students to Hawaii
by Stephen K. Ritter
December 20, 2010
Nervous energy filled the cavernous Kamehameha exhibit hall in the Honolulu Convention Center on Dec. 16, as the 237 finalists for the Pacifichem 2010 student poster competition set up their posters and awaited the judges.
"We can feel some tension among the finalists, because they all really want to win," said Mitsuo Sawamoto, the poster competition's coordinator and a polymer chemistry professor at Japan's Kyoto University. The competition is a premier event at Pacifichem, a chemical congress held in Hawaii every five years for countries that border the Pacific Ocean.
Sawamoto dashed off to give the 50 judges their final briefing before they engaged the students. As the students waited, some of them visibly practiced their oral presentations—mouthing words, gesturing with their hands, running their fingers over reaction schemes, and pointing to graphs and spectra. Others stood silently staring at their posters trying to focus. Still others, feeling ready to go, stood with their feet together, hands clasped. When the session was over and the judges had huddled to make their final decisions, 43 of the finalists were declared winners.
"This competition is an important aspect of the Pacifichem program," said Steven Holdcroft, a chemistry professor at Simon Fraser University, in Burnaby, British Columbia, and the conference's technical program chair. Of the approximately 5,900 posters presented at Pacifichem this year, 2,070 students entered the competition, he noted.
The conference's topical area coordinators worked with symposium organizers to screen the applications and judge the extended abstracts to select the finalists, Holdcroft explained. The number of finalists from each topical area was proportional to the number of applicants from each area. Once the finalists were notified in late July, they had five months to finalize their poster presentations and get ready for the final judging.
"The students take the competition very seriously, and they put a lot of time into their work," Holdcroft said. "For the winners, it is a significant achievement—a tremendous accolade to add to their résumé."
During the initial round of judging, each student was evaluated for the quality of their abstract and for the novelty and importance of the research, Sawamoto said. In Hawaii during the final round, each of the finalists made a five-minute oral presentation to at least two judges, he added. The judges spent an additional five minutes interviewing each student.
"The judges in the final round placed more emphasis on the students' poise, enthusiasm, and understanding of their research, rather than on the quality of the poster and the significance of the science," Sawamoto said.
The winners and their advisers were feted at a luncheon on Dec. 19, where the students received their awards—a certificate and a compact disc version of the Merck Index.
Anneli Kleyn, a student at Stellenbosch University, in South Africa, and one of the competition winners, said she enjoyed interacting with students from so many different countries. "This is a great conference, and a good opportunity for me to meet and listen to lectures from chemists when normally I would just be at home reading their research papers," Kleyn said. "The quality of the presentations is much better than the small conferences we usually are able to attend." Kleyn was optimistic that the networking at Pacifichem might lead to a postdoctoral position for her when she finishes her Ph.D. in a couple of years.
"I'd like to thank all of people who gave me advice and suggestions on my poster," added winner Azusa Iida of Nagoya University, in Japan. "The poster reflects not only my work, but that of my colleagues. I feel happy that it worked well to lead to a winner." Iida said the luncheon was a nice reward for her and other winners' efforts.
"It's exciting for us to have such enthusiastic students come here," Sawamoto said. "We have this competition so the students will be more committed to attend Pacifichem, not just to come so they can to go to the beach and go shopping—although we know they will do that. I hope this event ultimately further stimulates their research."
