He is currently an Associate Professor of Philosophy at the University of the Philippines Diliman. Before getting his tenure in UP Diliman, he had an extensive experience in teaching various ethics and philosophy courses at UP Manila (2005-2008) and UP Los Banos (2002-2003). He took his PhD in Philosophy in Norway at the University of Bergen and his MA and BA Philosophy degrees at UP Diliman. Prior to his studies abroad, he was able to secure several grants for international paper presentations. Two of them came from the Philippine Commission on Higher Education (CHED). His various engagements from 2011-2015 included being: a CHED Technical Reviewer on Philosophy, a trainer for Ayala Foundation’s Center of Excellence in Public Education, a resource person in a couple of UNESCO World Philosophy Day Celebrations, and a training consultant on various critical thinking skills program for public schools transitioning to the K-12 program. His PhD Research in the University of Bergen focused on an exegetical debate on Ludwig Wittgenstein’s later work Philosophical Investigations. That work involved conflicting interpretations on what it means to do philosophy as it uses language to overcome the limits of human thought. He discovered that this approach involves a return to a form of Socratic dialogue where the concern for logic becomes interconnected with ethics. Now that he has resumed his academic duties in UP Diliman, he is engaged in various projects and activities that relate to context sensitivity in ethics and logical reasoning. This includes membership in research ethics committees, writing a module on informed consent, teaching graduate seminars on philosophy of education and the philosophy of Ludwig Wittgenstein, researching on the ethics of mindfulness and vegetarianism, and investigating the nature of philosophical discussions in an online setting.
