Three academicians (mathematical and physical sciences) of the National Academy of Science and Technology (NAST) Philippines, a retired judge of the International Criminal Court (ICC), a health economics expert, and a political scientist are the latest professors emeriti from UP Diliman (UPD). This was announced by the Office of the Faculty Regent (OFR) in their official Facebook page, Opisina ng Faculty Regent.
Appointed by the UP Board of Regents on Sept. 26, at its 1393rd meeting, three out of the 12 newly-appointed professors emeriti are from the College of Science (CS). They are NAST academicians Jose Maria P. Balmaceda, PhD of the Institute of Mathematics (IM); Caesar A. Saloma, PhD of the National Institute of Physics (NIP); and Cesar L. Villanoy, PhD of the Marine Science Institute (MSI).
Also appointed professors emeriti are retired ICC judge Raul C. Pangalangan, JSD of the UP College of Law (UP Law), health economics expert Orville Jose C. Solon, PhD of the School of Economics (SE), and political scientist Teresa S. Encarnacion-Tadem, PhD of the College of Social Sciences and Philosophy (CSSP).
Five of the professors emeriti held key positions in the University. Balmaceda was the assistant vice president for academic affairs during the Nemenzo presidency (1999-2005). Saloma was the ninth UPD chancellor (2011-2014). Balmaceda, Pangalangan, Saloma, and Solon were deans of their respective academic units, with Balmaceda (2011-2014; 2014-2017), Saloma (2006-2009; 2009-2011), and Solon (2015-2018; 2018-2021) serving for two terms. Pangalangan was UP Law dean from 1999 to 2005. Meanwhile, Encarnacion-Tadem was the executive director of UP Center for Integrative and Development Studies (CIDS) from 2017 to 2023.
Villanoy is regarded as one of the pioneers of physical oceanography in the Philippines.
A professor at the IM, Balmaceda was elected to the NAST Philippines as academician in 2008. According to the NAST website, his “important contributions to group theory, representation theory, and algebraic combinations through his research publications;” his help “in the scientific education and training of the youth through mentorship of mathematics undergraduate and graduate students;” and his continuous engagement in “public service and extension programs, particularly teacher training and popularization of mathematics and science, and technical assistance to science and technology agencies and bodies” are his most significant contributions to science and the society.
A distinguished member of the mathematics community recognized here and abroad, Balmaceda has received various accolades. Among his awards are: the Achievement Award (Mathematical Sciences) of the National Research Council of the Philippines / NRCP (2000), Science Prize (Mathematics) of the Third World Academy of Sciences-NAST (1996), and Outstanding Young Scientist of the NAST (1995).

In a post at the MSI Facebook page, the institute credits Villanoy for his work that guided many “science-based interventions for disasters” including the early response to the 2023 Mindoro oil spill and the latest MT Terra Nova oil spill. The MSI also lauds Villanoy for mentoring young scientists, molding them into “versatile oceanographers” since establishing the institute’s Physical Oceanography Laboratory in 1992.
