What started your interest in Blood Transfusion?
It began with my experience in donating blood as a medical technology intern. My blood bank rotation at the Jose R. Reyes Memorial Medical Center and the Makati Medical Center (a government and private facility, respectively) in the Philippines further intensified my interest as it deeply shaped my understanding in this field, as it sits at the intersection of science, service, and humanity. I was drawn to the idea that a system—when done well—quietly saves lives every day. Seeing how one safe unit of blood could mean the difference between life and death made me want to contribute to strengthening that system.
How did this interest develop and what are your main topics of interest now?
After my internship and working at the Makati Medical Center, my interest further developed when I worked at the Dr. Erfan and Bagedo General Hospital in Jeddah, Saudi Arabia. I was a rotating medical technologist at the Blood Bank where I was able to encounter complex immunohematology cases and performing donor screening. After working there for a couple of years, I returned back to the Philippines where I worked at the Research Institute for Tropical Medicine under the Transfusion Transmissible Infections – National Reference Laboratory. Here we served as the apex laboratory for the blood services network conducting confirmatory testing on transfusion transmissible infections, provision of quality assurance activities, training of medical technologists on serological testing, research and the evaluation of in-vitro diagnostic assays. Over time, I engaged in research to improve national health policies in collaboration with the Department of Health. Despite the challenges and bureaucracies, engaging local stakeholders and international partners inspired me to further advance blood safety in our country. As my career progressed, my involvement expanded from laboratory work to national-level coordination, quality assurance, and policy support. This exposure allowed me to appreciate the complexity of maintaining a safe and sustainable blood supply, especially in resource-limited settings. Today, my main areas of interest include transfusion-transmissible infection screening, quality management systems, nucleic acid testing implementation, capacity-building, and promoting collaboration across blood services, regulators, and policy-makers.

What have been the most rewarding times in your career?
Research has been challenging to implement in the country, particularly due to given resource and system constraints. However, the publication of our first article on external quality assessment schemes for transfusion-transmissible infections in the Philippine Journal of Pathology marked an important turning point. It gave me the confidence to further pursue research as a tool for advancing blood safety. Encouraged by mentors, I went on to submit an abstract to the 2016 ISBT Congress in Dubai. Its acceptance was both humbling and energizing, as it opened new opportunities for learning and collaboration. The acceptance of our research on the Anti-HBc Seroprevalence in Vox Sanguinis, was a defining moment not only for me, but for our team at the Transfusion Transmissible Infections – National Reference Laboratory. The most rewarding moments however, have been those when collaborative efforts resulted in meaningful change—improvements in testing strategies, stronger quality frameworks, or increased confidence among blood service facilities. Knowing that these initiatives translate into safer transfusions and better patient outcomes is deeply gratifying.

What role have you been involved in within ISBT, how has this impacted your life?
I have been part of ISBT since attending my first congress in Dubai in 2016. Since then, I have engaged with the Society as an exempt, individual, and now affiliate member. The affiliate membership was one of our projects at the Philippine Blood Coordinating Council during the time of our past president, Mr. Antonio F. Domasian. Through ISBT’s congresses, educational programs, and scientific resources, I have been continuously exposed to the collective expertise of global leaders in blood safety and transfusion medicine. This exposure has significantly shaped my professional perspective, encouraging me to pursue continual learning and to critically evaluate how international standards and innovations can be adapted to local realities. ISBT has not only expanded my technical knowledge but has also strengthened my sense of belonging to a global community committed to improving transfusion practice. The lessons I have gained continue to inform my work in the Philippines, guiding efforts toward safer, more equitable, and sustainable blood services.

Who have been the most influential people in your career?
In terms of blood safety, the pathologists working in our blood service facilities have played a prominent role in how I view responsibility and accountability in transfusion medicine. We are a fairly small community in the country and their commitment to evidence-based decision-making, patient safety, and ethical practice has shaped my own approach to quality and governance. Equally influential have been laboratory professionals and blood service staff on the front lines, whose diligence and consistency ensure that standards are upheld every day. Together, they have reinforced my belief that a safe blood system is built not only on technology and policies, but on people who uphold these principles with integrity. Special mention to my colleagues at the Research Institute for Tropical Medicine and the Philippine Blood Coordinating Council!
What are your personal goals in relation to ISBT?
ISBT has long been a source of inspiration in advancing transfusion medicine worldwide. My personal goal is to contribute meaningfully to the Society by actively engaging in its programs, congresses, and scientific platforms, particularly through sharing experiences and practices related to blood safety in the Philippines. I hope to help enrich global dialogue by offering perspectives from a resource-constrained setting, while also learning from others and translating these insights into sustainable improvements in our national blood system.

What energizes you most at work?
What energizes me most is working alongside colleagues who are deeply committed to their work. Their passion, sense of purpose, and willingness to go beyond what is required continually motivate me to do more. Seeing that shared dedication—especially when it translates into meaningful impact for patients and the health system—gives me both energy and direction. At the bottom of this are family and friend, who ground me, support me unconditionally, and remind me why the work we do matters beyond the laboratory. Their encouragement gives me the strength and clarity to keep going, even during the most demanding moments.
What do I do in my spare time?
I now prioritize moments that allow me to reset—spending time with family and friends, hiking, free diving, and traveling when possible. These experiences help me maintain balance and bring fresh perspective back into my professional life.

Do you have a hidden talent?
People often assume I’m quite serious, but not many know that I used to play guitar in a band (I still play on some occasions, with my family now being my audience). Music has always been a fun way for me to unwind and express a different side of myself.
Finally, what do you wish to add, or what would you like to say to our Transfusion Today readers?
Transfusion medicine is ultimately built on trust—between donors and recipients, science and service, and local action and global standards. As our field continues to evolve, I hope we remain firmly grounded in collaboration, equity, and compassion, ensuring that safe and sufficient blood is accessible to all who need it. To my colleagues in the Philippines, I encourage you to actively participate, share your experiences, and engage more deeply—both within our national programs and in the global ISBT community. Our local realities and innovations matter, and by contributing our voices, we help strengthen not only our own blood system but the global transfusion community as well.
