Andrian Gajigan is a biochemist and oceanographer. His research interests span from the molecular level to ocean scale processes. This includes microbial oceanography, marine virology, genomics, and gene regulation. He has participated in several expeditions in the Atlantic and the Pacific Ocean. Previously, Gajigan contributed to a larger effort to develop an early predictive system for harmful algal blooms (HABs, aka red tide). In his work, he outlined a microRNA-mediated mechanism that allows corals to adapt to heat stress. He also described the diversity and community structure of microbes in different regions in the Philippine seas.
Gajigan earned his BS in Biochemistry and MS in Marine Science at the University of the Philippines. He is currently based in Honolulu, pursuing his PhD in Oceanography at the University of Hawai‘i at Mānoa, focusing on phytoplankton viruses.
