A team of sustainability researchers from UST’s Research Center for Social Sciences and Education recently published a paper on how sustainable tourism can be promoted in the island of Siquijor, as envisioned from the expressed needs of its inhabitants. Following a training needs analysis and applying the Sustainable Tourism and Human Capital Development philosophies, the paper co-authored by Prof. Alain Jomarie G. Santos, PhD, Prof. Arlen A. Ancheta, PhD, Prof. Moises Norman Z. Garcia, PhD, and Prof. Maria Rosario Virginia Cobar-Garcia, PhD provided data-driven bases for future training programs.

The new study, entitled “Conservation of Sustainable Ecotourism on the Island of Siquijor through Sustainable Alternative Livelihoods, Training and Development,” was published in The International Journal of Social Sustainability in Economic, Social, and Cultural Context. The participants, who were inhabitants of the island, favored sustainable ecotourism but expressed the need for intensive capacity-building in both interpersonal and computer skills. In terms of actual livelihood activities, the participants identified housekeeping, healing massage training, and tour guiding/tour car driving as immediate areas of concern. To help manage the desired influx of tourists, the residents likewise expressed the need for basic first aid training.

Santos is the incumbent Chair of the Department of Economics of the Faculty of Arts and Letters, while Ancheta teaches at the Graduate School. Meanwhile, the Garcias are academic researchers of the Department of Biological Sciences of the College of Science.

Within Taal Lake is the much-loved yet endangered Sardinella tawilis. The much-loved fish delicacy is a staple of Luzon, yet has been marked Endangered in recent years. The recent eruptions of Taal Volcano have posed further threats to the species, and a new study uncovers its updated feeding ecology, which may help creating an ecosystem-based conservation and management strategy so that the species can survive.

The paper “Shifts in the feeding ecology of the endemic and Endangered Sardinella tawilis in Lake Taal, Philippines” showed that the tawilis, which have been found to feed on zooplanktons,preferred “cyclopoid copepods and [showed a] noticeable increased preference for Moina micrura, Ceriodaphnia cornuta, and Bosmina fatalis.” This showed a shift from its earlier preference for calanoids. The findings were elicited from an application of stable isotope analysis and gut content analysis.

The new study was published on June 5, 2025 in Endangered Species Research, Volume 57, and was authored by a team of scientists from UST, De La Salle University, University of Rizal System, and the Department of Science and Technology. The authors are: Dale Anthony L. To (UST, DLSU), Asst. Prof. Elfritzson M. Peralta, MSc (UST), Justine R. De Leon (UST), Alexis E. Belen (UST), Lloyd Matthew L. Pineda (UST), Inst. Walled T. Ali (UST), Miguel Angelo F. Dollete (UST), Inst. Ray Allan N. Zafra (UST), Norman Mendoza (DOST), Prof. Richard Thomas B. Pavia, PhD (UST), Assoc. Prof. Dino T. Tordesillas, PhD (UST), Jonathan Carlo A. Briones (UST, URS), and College of Science Dean Rey Donne S. Papa, PhD.

An appreciation by children for the rich biodiversity of the island of Siargao became the main goal of a project of Thomasian researchers, who received funding from the Department of Science and Technology (DOST) – National Research Council of the Philippines (NRCP).

A team led by Biological Sciences Professor Cecilia I. Banag-Moran, Dr. rer. nat. developed digital and print learning materials for children, whose schools now adopt the tools. In an announcement by the NRCP, the funding agency announced that the Department of Education – Schools Division of Siargao approved the use of the materials to “strengthen literacy and promote environmental education for young learners.”

The materials include a printed workbook, the Siargao Flora & Fauna Puzzle mobile game, and twenty-one (21) animated videos focusing on what comprise Siargao’s famed biodiversity. The materials have a focus on mangrove research areas.

Banag-Moran’s team is composed of the following academic staff: Inst. Jorge Anton D. Ordas, MSc, Inst. Genea Nichole Cortez (content writer for the workbook), MSc, Asst. Prof. Mae Lowe L. Diesmos, MSc, Academician Mudjekeewis Santos, PhD (Graduate School), and Academician Arvin Diesmos, PhD.

The project was based on a 2019-2020 study entitled “Assessment, Inventory, and Biological Field Survey of Flora and Fauna of the Mangrove Forests in Del Carmen, Siargao Island.” The team worked closely with Del Carmen Mayor Hon. Alfredo Coro, Jr. and his team for the endeavor.

A 2025 study in the journal Nature looked at promotion criteria for academic researchers in 190 academic institutions and 58 government agencies worldwide and uncovered that these criteria generally bring about normative career progression instead of one that embraces diversity.

The study, entitled “Regional and institutional trends in assessment for academic promotion,” was co-authored by Prof. Thomas Edison E. dela Cruz, Dr. rer. nat., a full professor of the Department of Biological Sciences and Member of the country’s Teacher Education Council.

Surveying a total of 314 policies pertaining to full professorship, the study acknowledged the “assessment as research performance [as a] vital tool in upholding the highest standards of quality, with selection and competition believed to drive progress.” The study covered a total of 121 countries, with 32 from the Global North and 89 from the Global South. While there were marked differences between Global North and Global South, as well institutional and national policies, the study found that this diversity was less present across disciplines—despite the inherent uniqueness of each.

The provided strategic implications for researchers, research managers, and national governments.

Two Thomasian scientists are joining forces to find a possible alternative therapy to multidrug resistance. With funding from the Virology and Vaccine Institute of the Philippines and support from the Department of Science and Technology – Philippine Council for Health Research and Development (DOST – PCHRD), Drs. Donna May D.C. Papa (Department of Biological Sciences – College of Science) and Maria Rhona Gatpandan-Bergantin (Faculty of Medicine and Surgery) are working on a three-year project targeting infections of multi-drug resistant Acinetobacter baumanni. 

Dr. Papa, who leads the three-year project which began in July 2024, said that the project aims to “isolate bacteriophages infecting various clinical strains of A. baumanni collected from different hospitals and to produce a working prototype of phage formulation—composed of characterized bacteriophages that show high viability for therapeutic use.” In particular, the study aims at potential intravenous administration of the treatment using bacteriophages, which are a group of viruses aimed at targeting bacteria.

So far, the team has collaborated with ARSP sentinel sites and tertiary hospitals to collect water samples and doing enrichment set-ups and testing the filtrates. The team also procured necessary equipment, which will be transferred soon to the UST-Dr. Tony Tan Caktiong Innovation Center in Santa Rosa, Laguna.

Rev. fr. Nicanor Pier Giorgio Austriaco, O.P., PhD, SThD, academic researcher of the Department of Biological Sciences and the Faculty of Sacred Theology, was named the 2024 National Research Council of the Philippines (NRCP) Gabay Awardee for his 2SIR-VD Model for vaccine distribution in the Philippines during the first year of vaccine rollout.

The study, co-authored by fr. Austriaco with Mary Chelsea E. Diego and Red Lazaro of the Department of Biological Sciences, Angus White of Providence College – USA, and Allan Paola L. Almajose of the Department of Chemical Engineering, adapted a susceptible-infected-recovered model to help vaccinators administer the needed COVID-19 deterrent and arrest the spread of the disease. The model targeted the National Capital Region as the main focus area of widespread vaccine distribution to mitigate viral transmission, which was high in the capital, while the rest of the archipelago can first focus on medical frontliners, senior citizens, and adults with comorbidities.

The study, entitled “,” was published in the Philippine Journal of Science and helped the Philippine government in distributing limited vaccine supply to the sectors who needed it most.

The NRCP Gabay Award is given annually to active NRCP members whose research works have resulted or translated to adopted technologies and policies; or have informed local and national policy-making.
