Two graduate students and a postdoctoral researcher with the University of 51ÂÒÂ×»»ÆÞʻi at Mānoa¡¯s were selected to be .

A highly competitive selection through the Department of Energy’s National Microbiome Data Collaborative program, the Ambassador Program utilizes a cohort-based learning approach to train and support early career researchers who are familiar with the challenges of discovering and accessing microbiome data; committed to working with the NMDC to make microbiome data findable, accessible, interoperable, reusable (FAIR); and committed to inclusion, diversity, equity and accountability.

Andrian Gajigan

Gajigan, who is pursuing a doctoral degree in with advisor and professor Grieg Steward, is investigating the interactions and dynamics between phytoplankton and giant viruses in the ocean. Gajigan is developing and observing lab-based model systems as well as field investigations, specifically, the role of giant viruses in algal bloom demise and phytoplankton succession.

“I am deeply fascinated with microbes because of their often underappreciated importance,” said Gajigan. “The world would cease to exist if we were to remove microbes on the planet. They are the chemists and sentinels of Earth¡¯s climate.”

Kacie Kajihara

Kajihara graduated from UH Mānoa with a master’s degree in botany with advisor Nicole Hynson, who is a professor in the (PBRC). She will soon start the to pursue a doctoral degree with Michael Rapp¨¦, professor at the , where she will study the genomics and ecology of SAR86, a globally prevalent group of marine bacteria.

“Through the Ambassador Program, I¡¯ve been able to receive training on FAIR data and other data standards that put equitable science at the forefront, and I look forward to sharing this information with the UH community,” said Kajihara.

Nicola Kriefall

Kriefall is a postdoctoral researcher in PBRC co-advised by Matthew Medeiros and Hynson. Her research focuses on the roles that microorganisms play in shaping food webs, specifically looking at small pools of water where mosquitoes begin their life cycle. This area of research holds additional potential for information to combat the mosquito¡¯s disastrous ecosystem and human health impacts—especially in 51ÂÒÂ×»»ÆÞʻi, where they are invasive.

“It¡¯s endlessly fascinating to me that single-celled microorganisms we can’t even see with the bare eye are able to take us down or prop us up,” Kriefall said. “For instance, they can be pathogenic and make us ill or reside in our gut and help us digest things we otherwise wouldn’t be able to.”
