“Salmon lice is a huge problem, and they couldn’t use some of the anti-lice compounds,” she said. Given that some of the salmon were raised for human consumption, alternative measures were sought. “Sometimes they would bring out a bag of rotting onions from the tank because they were hoping it would keep the lice away. It was the only thing they had at the time.”
A vaccine could change that. Numerous farms sought to develop and use antiviral vaccines for their struggling marine life, which Leong’s work made possible.
Moving forward and across the ocean
After her time at Oregon State, she returned to Hawaii to help take care of her family, including her now 101-year-old mother and 103-year-old father. Departing from Oregon State meant she had to drop her virology research.
She landed a new position as director of the Marine Institute at the University of Hawaii at Manoa. The problem was she is a microbiologist – not a marine biologist.
When she arrived, the lab needed a microbiology background in aquaculture, especially in fish rearing and coral disease research. With 17 other faculty members, Leong led the Hawaii Institute of Marine Biology, including more than 50 graduate students.
Despite being an ocean away, she aimed to maintain her strong Oregon roots. “I used my own funds to bring some of the faculty over. I tried very hard to keep those friendships very strong because I didn’t want to leave them.”
Leong's leadership roles grew including serving as the chairman of the Board of Directors for the Center for Tropical and Subtropical Aquaculture, the president of the National Association of Marine Laboratories, and on the executive secretariat for the National Advisory Committee on Development and Assessment of Climate. When she retired, she thought about stopping science but when her friends kept calling her up to edit new books, she couldn’t resist.
When recalling her wild water adventures, she offers advice for aspiring scientists. “When I was young, I wish I knew to choose subjects and people not because they make you feel good, but because they are doing wonderful things for science and society,” Leong said. “Look to the future and decide what it is that you want, short and long-term, and then make the decision.”
Currently, she enjoys painting, playing piano, growing tomatoes, embarking on boat trips to Indonesia, and engaging in things she didn’t have time for before. Not to mention creating more memories with her husband in a marriage of 57 years and counting.
Even though many years have come and gone, she doesn’t forget the people who supported her through the struggles and the triumphs.
“I grew up as a scientist, teacher, and communicator at Oregon State,” Leong said. “My colleagues have been supportive and the College of Science administration as well as the College of Agricultural Sciences were so helpful as I was struggling as a young professor.”
