The College of Natural Sciences (CNS) held its annual Student Research Congress at the CAS Little Theater on May 11, 2026, opening its doors to students, faculty, and staff for scientific exchange and academic recognition.
The event highlighted innovative studies presented by CNS students in the fields of science, technology, agriculture, and natural resource management, emphasizing the college's role in advancing research for local and global challenges.
BS Biology Students formally opened the program with Doxology and the singing of the Philippine National Anthem, followed by welcome remarks by the CNS Dean, Dr. Sherlyn C. Tipayno. Following this, Mr. Christian Mark S. Guyo, College Research Coordinator, outlined the Rationale and Mechanics of Research Presentations, while the Department Research Coordinators introduced the line of panelists.
Three concurrent breakout sessions showcased diverse research categories, namely, SCIENCE & TECHNOLOGY Agriculture, Aquatic, and Natural Resources (S&T AANR) with panelists Prof. Reymark C. Ereje, Dr. Nordalyn B. Pedroche, and Prof. Eugene Lorence R. Logatoc. SCIENCE & TECHNOLOGY Food, Industry, Energy, and Emerging Technologies (S&T FIEET) with panelists Dr. Norbet Q. Angalan, Prof. Lesley Dale G. Umayat, and Dr. Darwin A. Basquial. Finally, SOCIAL Agriculture, Aquatic, and Natural Resources (SOCIAL AANR) with their panelists Dr. Apler J. Bansiong, Dr. Lynn J. Talkasen, and Engr. Marvin T. Valentin.

Student Authors, Ezrael D. Balisong, Christian Joseph R. Soriano, and Janielle D. Tacio, championed the S&T FIEET category with the study entitled โCharacterization, Optimization, and Biomedical Applications of Silver Nanoparticles Synthesized by ๐๐ด๐ฑ๐ฆ๐ณ๐จ๐ช๐ญ๐ญ๐ถ๐ด ๐ง๐ถ๐ฎ๐ช๐จ๐ข๐ต๐ถ๐ด Isolated from ๐๐ฐ๐ง๐ง๐ฆ๐ข ๐ข๐ณ๐ข๐ฃ๐ช๐ค๐ข Mucilage.โ
Soriano said that it was an honor for their group to win and that one of the best parts was learning about other students' studies.
In highlighting their contribution to the society and scientific community, Soriano added that they have found that the capacity of an organism dubbed as a "laboratory contaminant" to be functional with beneficial applications. Adding to this, their group also tried to address the utilization of waste products from the coffee industry of Benguet by using the mucilage and pulp that are usually discarded during processing.
While he said that there is still some room for improvement in their study, he further noted that, "I think that's the beauty of science, you get to learn new things every day, and every day is a new opportunity to make things better, and understand things better.โ

In the S&T AANR, Biology students Samantha Descalzo, Euan Judg Rebolledo, and Kevin Tima-ang emerged as first placers with their study entitled โComparative Pharmacognosy of ๐๐ข๐ด๐ฎ๐ข๐ฏ๐ฏ๐ช๐ข ๐ฑ๐ช๐ฑ๐ฆ๐ณ๐ช๐ต๐ข from Selected Mountain Sites in the Cordillera Central Range, Northern Philippines.โ
According to Tima-ang, although they struggled with time constraints and dealt with limited resources and facilities in conducting their study, the group found strength in motivating one another throughout the research process.
Providing insights on their research, Tima-ang explained that the increased phytochemical content of ๐. ๐ฑ๐ช๐ฑ๐ฆ๐ณ๐ช๐ต๐ข from their study provides additional knowledge about the effectiveness of the plant, aiding treatment practices in the Cordillera.

BS Environmental Sciences student authors Zhandrae O. Olsim, Mylene Cara B. Sabelo, Jethro V. Sagsagap, Jemmiah B. Tamayo, and Harvel H. Tiago admitted that being awarded first place in the SOCIAL AANR was a humbling experience, with their study โLand Use and Land Cover Transformations (2010-2024) and Local Community Perceptions of Watershed Management in Busol Watershed, Baguio City.โ
According to them, โActually, we didn't expect to win, we just did our best in presenting our research paper. A huge thanks also to our supportive adviser (Maโam Janice Balangen) because of her guidance.โ
Reflecting on their success, the group said they had to face challenges along the way, especially with financial matters, considering that their research site was conducted outside of La Trinidad, coupled with time constraints whilst conducting their research along with their other academic loads.
โThe first struggle of our thesis is financial, our thesis was located in Busol area so transportation money is a must together with money for food, not only for us but also for the stakeholders that we interviewed. Another challenge we encountered was time management, time constraints are the main struggles mainly because we were conducting our thesis with several academic undertakings.โ
Despite this, their research provided the importance of the watershed to the ecology, aiding community residents.
โCritical watersheds are (an) important source of water resource and ecosystem services. Understanding the perspectives of the community on the changes of watershed and its management would help to be (an) integrated, cohesive and community based management strategy for watersheds in our locality.โ

Addressing the scientific community, Tipayno said in her brief address that, โActually as people in science, we are called to discover the truth that already exists, that answers all the phenomena that occurs in our world. โYon ang ating responsibilidad. So when youโre in science it almost becomes an obligation to perform those.โ
She further said that the research colloquium is a testament of contribution to the growing academic and scientific knowledge, adding that scientific works are not useful until they are shared and that the forum is a way by which student-researchers can share their work.
The event concluded with the closing program featuring the awarding of certificates to panelists and the participants of the respective categories by the college dean and department chairpersons.
Overall, the podium finishers garnering a score of 85 and above will be presenting their study at the University-wide Research Congress on June 4 to 5, 2026.
Listed are the awarded research titles and student authors:
