When I entered UP, I was initially undecided on what career I should choose for myself. I knew that I wanted to study chemistry, but at that moment, it was still unclear to me what I wanted to do after finishing my studies.
Fortunately, I took an elective course in marine science under Dr. Malou San Diego-McGlone where my intrigue for the oceans sparked for the first time. I also had the chance to participate in immersion programs with the fisherfolk community in Cabangan, Zambales. These encounters deeply inspired me to use my knowledge in chemistry as a tool to better understand our oceans and harness our resources for the benefit of the Filipino people. I eventually took the leap of faith and decided to pursue research in marine science.
As a graduate student at UP MSI, I gained a deeper understanding of the complexity of the ocean and the incredible diversity of the many critters that call the seas their home. It made me appreciate how everything in the ocean is profoundly interconnected โ from the ebb and flood tides influencing the reproductive cycle of fishes, to how the slightest changes in temperature and pH can devastate coral growth; from the seemingly unassuming phytoplankton playing a crucial role in the carbon cycle and affecting weather patterns, to how ecological relationships between marine organisms, forged over millions of years of evolution, give rise to chemical compounds that may become one day be used to treat humanityโs most debilitating diseases.
Doing research is indeed challenging. Sometimes, experiments fail, such as when peaks magically disappeared in your chromatogram or when the assay that you worked overtime yielded inconclusive results. But I learned that embracing uncertainties and setbacks will always be part of science.
In MSI, I am blessed to have labmates who supported me with their encouragement and good company. I am also grateful to Dr. Lilibeth Salvador-Reyes for her excellent mentorship and for inspiring me to pursue my scientific passion, along with the rest of the MSI faculty for nurturing us to grow holistically as marine scientists.
Beyond offering a descriptive view of nature, pursuing research in marine science has allowed me to marvel at the ocean and its intricate workings. As my understanding of the ocean and everything beneath it grows, so too does my love for it.

Ernest Guiller Pineda is an MSc graduate of the Marine Pharmacognosy Laboratory led by Dr. Lilibeth Salvador-Reyes. He is now a graduate fellow of DOST-SEIโs Career Incentive Program, and has returned to UP MSI to continue studying shipworms and shipworm symbionts as a source of novel therapeutics. Ernest began his fellowship this July 16, shortly after his graduation.
