Mark Jay Cristino, a third-year BS Mathematics with Research Statistics student, will represent the Department of Science and Technology - Science Education Institute (DOST-SEI) Region XI in the National Patriot Scholars Congress (NPSC) 2025 at the Dusit Thani Mactan Cebu, Lapu-Lapu City, starting today, September 3, until September 6, 2025.

The NPSC gathers DOST-SEI scholars across the country to foster patriotism, leadership, and prepare them as emerging civic leaders of the nation. This year’s NPSC ushers in the theme, “Cultivating the Next Generation of Filipino Science Volunteers.”

Cristino is the lone participant from Davao Oriental State University (DOrSU) and is joined by twenty-one (21) other scholars from eight ( 8 ) different universities in the region. Cristino also represented the university at the International Summer School at Silpakorn University in Thailand earlier this year.

​
In recognition of his unwavering support and invaluable contributions to environmental protection, Davao Oriental State University (DOrSU) President Dr. Roy G. Ponce has been honored with the Outstanding Stakeholder Award by the Department of Environment and Natural Resources (DENR) XI.
​
The recognition was conferred during the Outstanding Stakeholder Awards Ceremony held today, June 27, at the DENR Regional Office XI Conference Room in Davao City. Representing Dr. Ponce at the event was Ms. Amy G. Ponce, who received the award on his behalf.
​
The award is bestowed upon distinguished partners who have demonstrated exceptional commitment in advancing the DENR’s vision of 𝘢 𝘯𝘢𝘵𝘪𝘰𝘯 𝘦𝘯𝘫𝘰𝘺𝘪𝘯𝘨 𝘢𝘯𝘥 𝘴𝘶𝘴𝘵𝘢𝘪𝘯𝘪𝘯𝘨 𝘪𝘵𝘴 𝘯𝘢𝘵𝘶𝘳𝘢𝘭 𝘳𝘦𝘴𝘰𝘶𝘳𝘤𝘦𝘴 𝘢𝘯𝘥 𝘢 𝘤𝘭𝘦𝘢𝘯 𝘢𝘯𝘥 𝘩𝘦𝘢𝘭𝘵𝘩𝘺 𝘦𝘯𝘷𝘪𝘳𝘰𝘯𝘮𝘦𝘯𝘵.
​
Under Dr. Ponce’s leadership, DOrSU has remained to be an active partner of the DENR in advancing environmental initiatives. The University’s strong engagement in research, community extension, and environmental education has significantly contributed to the success of national and local conservation programs. Through various interdisciplinary projects, DOrSU has helped raise awareness, promote sustainable practices, and empower communities to become active stewards of their environment.
​
Beyond his institutional role, Dr. Ponce is also known for his grassroots environmental advocacies. Among the most notable initiatives he conceptualized is the Plastic Education and Exchange Program, which he launched in Barangay Taganilao, City of Mati. The program engages local children in collecting plastic litter along shorelines, which they exchange for school supplies and essential goods. To deepen impact, it includes micro-lectures on plastic pollution and environmental responsibility, conducted with the help of community volunteers.
​
This simple yet powerful approach has inspired behavioral change at the local level and has been replicated in other areas of Davao Oriental, with support from both local governments and civil society groups. The initiative continues to mobilize volunteers and serves as a model for sustainable, inclusive environmental action.
​
Joining Dr. Ponce among this year’s awardees are the City Government of Mati, EnP Joseph G. Porgatorio, and several other partners who have made notable contributions to the DENR’s programs and objectives.
​
The recognition reaffirms Dr. Ponce’s enduring commitment to environmental stewardship and DOrSU’s ongoing efforts in advancing its regenerative futures vision.

𝙉𝘼𝙆𝙃𝙊𝙉 𝙋𝘼𝙏𝙃𝙊𝙈, 𝙏𝙃𝘼𝙄𝙇𝘼𝙉𝘿 — Students and faculty member from the Bachelor of Science in Mathematics (BSM) Program of Davao Oriental State University (DOrSU) took part in the Summer School in Statistics hosted by the Faculty of Science, Silpakorn University (SCSU) from May 30 to June 2, 2025. With the theme “Gamifying Stats,” the international academic event gathered participants from Thailand, the Philippines, and Indonesia, promoting fun, engaging, and practical approaches to learning modern statistical methods.

The DOrSU delegation included Mr. Mark Jay A. Cristino, a second-year BSM student taking Research Statistics, Mr. April Ness C. Dacup, a third-year BSM student, and Dr. Rodrigo A. Salimaco, Jr., BSM Program Head.

This collaborative activity is one of the early outcomes of the Memorandum of Understanding (MoU) between DOrSU’s Faculty of Computing, Engineering, and Technology (FaCET) and SCSU, formally established in February 2025. The MoU aims to strengthen academic exchange, research collaboration, and capacity-building between the two institutions.

Participants in the summer school engaged in academic sessions covering Regression Analysis, Classification Tree, Experimental Design, and laboratory-based statistical exercises, all designed to demystify statistical concepts through gamification and interactive programming.

In addition to academic enrichment, the event featured cultural workshops that offered participants a taste of Thai heritage. These included:

🫙 Making herbal inhalers
🖌️ Sculpting clay figures
🎨 Painting eco-bags using natural flower stamps
🛍️ Shopping at a local Thai market

The Summer School in Statistics provided a unique platform for participants to enhance their statistical knowledge, develop cross-cultural connections, and foster international academic camaraderie—aligning with DOrSU’s vision of cultivating globally competitive graduates and educators. #

We proudly congratulate our Program Head, 𝐃𝐫. 𝐑𝐨𝐝𝐫𝐢𝐠𝐨 𝐀. 𝐒𝐚𝐥𝐢𝐦𝐚𝐜𝐨, 𝐉𝐫., for officially becoming an 𝘼𝙨𝙨𝙤𝙘𝙞𝙖𝙩𝙚 𝙈𝙚𝙢𝙗𝙚𝙧 of Division II - Mathematical Sciences, of the National Research Council of the Philippines (NRCP)! He took his oath on May 2, 2025, during the Scientific Session and Business Meeting of NRCP Division of Mathematical Sciences held via Zoom.

This important engagement reflects Dr. Salimaco's commitment to advancing research in mathematical sciences and opens new doors for collaboration, knowledge sharing, and contributing to national development through science and innovation.
