What is research for if not to find a technical solution to a problem and develop something useful which can be implemented for the benefit of mankind?

This mantra was precisely the driving force behind all the research endeavors and research-related coaching activities of one of the “just starting out” yet highly admired teachers of Philippine Science High School Southern Mindanao Campus, Ms. Jessa Mae A. Villanueva.

In fact, when asked as to what was her and her co-author’s inspiration in coming up with the research entitled Antimicrobial Property of Sodium Alginate/TiO2 Nanocomposite Film, she said that, “One time, we visited the farmers in Calinan and learned that their persistent problem is on how to prolong the shelf life of their crops. This was the very reason why we conducted this research to look for solutions that could help farmers.”

Basically, the study shows that Sodium Alginate/TiO2 composite films can indeed be used in the food industry as an antibacterial film. Given its many possible uses in agriculture and food industry, the study was thereby acknowledged and peer-reviewed by the Philippine Journal of Science and published last September 2018. Here’s the link:

Ms. Villanueva, who has been a recipient of a number of research-related awards such as second place in the DOST, 6th Health Research & Development Expo and second place in poster presentation in the 11th PNHRS Week, shared that the current innovations in food packaging systems, including the use of polymers, hydrogels and nanoparticles to increase the shelf life of food has really been her main research interest.

With her passion and love for research, it is not a wonder that even her research advisees/students in the campus were award-winners too in different research-related contests here and abroad such as the Malaysian International Young Inventors Olympiad 2018, Project BT 2018, Restoration Exology Society of the Philippines Saving the Cordilleras Ecosystem Network (RESPhil-SCENE), Inc. 8th National Conference, and Global youth Science and Technology Bowl 2020, among others.

As a message to everyone, Ms. Jessa Villanueva has this to say: “Go out and look for research problems that are practical. Those that can actually help the society.”

About the Published Faculty:

Ms. Jessa Mae A. Villanueva finished BS Food Technology degree at the University of the Philippines Mindanao and is currently taking up MS Food Science at the same institution. For this school year 2020-2021, she is teaching Integrated Science II to Grade 8 Rosal students, serving as Research 1 Teacher/Adviser (Materials Science) and also as Research I Unit Head, and at the same time,   as Research 3 Teacher/Adviser, while being the Homeroom Adviser of Grade 8 Rosal.

“Research should be pursued to benefit humanity.”

This was the answer of Mr. Michael A. Casas, one of our faculty at PSHS SMC when asked about his philosophy in conducting research. He added that as a research adviser, he mentors his students to conduct researches that will have a positive impact to communities.

As an educator, Mr. Casas was involved in funded research projects on water quality, environmental science, natural products, and analytical chemistry collaborating with experts in the field.

His research project with Dr. Anthony C. Sales, Ms. Ludivina M. Porticos, Ms. Hydie R. Maspiñas, Mr. Porferio R. Jabla and Ms. Ma. Annabelle S. Jabla entitled “Assessment of the Extent of Implementation of Standards and Procedures for Water Safety in the Philippines” was published in BMJ Open, an online, open access journal.

The research looks into the extent of implementation of the water safety plans among drinking water providers in the Philippines.

Mr. Casas shared that he targets to publish more researches and the researches of his students in support of the vision of the Philippine Science High School Southern Mindanao Campus Director Dr. Jonald Fenecios to strengthen the research and publication culture of PSHS SMC.

About the Published Faculty:

Mr. Michael A. Casas is an alumnus (Batch 2006) of PSHS SMC. He obtained his Bachelor’s Degree in Chemistry from Ateneo de Davao University and conducted his research on natural products under Dr. Lourdes Simpol. His undergraduate research won numerous awards including the prestigious BPI-DOST Science Award in 2010 and emerged as the 2nd-runner-up for the Best Project of the Year competition. He finished his Master’s Degree in Chemistry at Ateneo de Davao University in 2016 and conducted his research on chromatography and separation science under Dr. Agnes T. Aranas. He was also able to work on researches funded by the Department of Science and Technology. Mr. Casas is currently teaching Chemistry and Research, serves as the coordinator of the Innovation and Technology Support Office and serves as the Assistant CID Chief of the Natural Science and Research Department of PSHS SMC.

“I'm committed to create and share new information. Hopefully my peers in Pisay also grab every opportunity they can get to share knowledge to the world.”

This was expressed by Chemistry teacher, Research 3 Unit head, and Research 2 and 3 adviser Le Grande O. Dolino pertaining to not just one but three of his research works published in Thomson Reuters/Scopus indexed journals, namely: Journal of Chemical Education, Philippine Journal of Science, and Foundations of Chemistry.

Mr. Dolino published a paper in August 14, 2020 titled “Insights from Teaching Chemistry Writing Online” in Journal of Chemical Education ( His research studied how teachers can better carry out writing-related activities such as laboratory reports in Chemistry and in other science subjects online.
He, in collaboration with Dr. Doris B. Montecastro and Fr. Antonio M. Basilio, likewise put out the research “Low-cost Recovery of Bromelain Solids from Industrial Pineapple Peel, Pulp, and Core Wastes Using Ethanolic Cashew Leaf Polyphenol” on September 2020 in Philippine Journal of Science ( This study introduced an alternative procedure in getting Bromelain solids from pineapple core and pulp which could be beneficial to pineapple farmers.
Prior to joining Pisay, Mr. Dolino also published an article in Foundations of Chemistry in 2017 ( This study elucidated the distinction between chemistry and other allied sciences.

Campus Director Jonald P. Fenecios lauded him for his achievements saying, “Research publication is truly one great leap in human resource development. That is why it is one of my thrusts as your new Director. I would like to call on for more teachers to do the same.”

About the published faculty:

Le Grande Dolino obtained his Bachelor of Science in Chemistry from Ateneo de Davao University and his Master of Science in Applied Mathematics from the University of Southeastern Philippines. His main research interests include chemistry education particularly in the transfer and development of student research skill.
