About Me

Hi! I am Jomar, a Full Professor of Mathematics at the University of the Philippines Los Baños (UPLB). I am honored to be recognized as a UP Scientist 3, and to hold the position of Dean at the UPLB Graduate School. Additionally, I am a Junior Associate at the Quantitative Life Sciences Group of the Abdus Salam International Centre for Theoretical Physics (ICTP) in Trieste Italy.

I am affiliated with various organizations, including the UP Resilience Institute (as fellow), UP COVID-19 Pandemic Response Team, and the UP Open University. As a science communication advocate, I support data-driven policy/decision-making, and work with the Department of Science and Technology to create science education videos and modules (e.g., for the nuLab Science bus).

Over the years, I have served as a consultant for numerous organizations, such as the Asian Development Bank, United Nations Population Fund, Zuellig Family Foundation, World Vision/START Network, Philippine Rice Research Institute, Department of Finance, Task Force T3, Supreme Court of the Philippines, and Province of Bataan. I have also held positions in the Governing Board of the National Research Council of the Philippines, and mentored in the Future Leaders Programme of the National University of Singapore.

I am proud to be a proponent and co-chair for program implementation of the first and only doctorate degree in Applied Mathematics in the Philippines, the PhD in Applied Mathematics program, as well as the PhD by Research in Data Analytics and Informatics program at UPLB. Moreover, I am a founding member of the Philippine Society for Mathematical Biology, which organizes the annual International Workshop on Mathematical Biology (IWOMB).

As an advocate for spreading data analytics across the Philippines, I am the architect behind the highly-rated and sought-after Data Analytics for the Future (DAF) X: a comprehensive 5-day short course offered by the UPLB Graduate School.

My research interests lie in mathematical modeling, data analytics, and quantitative risk assessment of complex biological and social systems. I am thrilled to have been recognized for my contributions, such as being awarded Outstanding Young Scientist by the National Academy of Science and Technology and receiving the One UP Professorial Chair for Outstanding Teaching and Research. The UPLB Mathematics Division also recognized me as an Outstanding Mathematics Instructor.
