Informed by his education and experience in engineering, statistics, and human rights work, Xavier collaborates with communities to create positive impact for LGBTQI people and people living with HIV through scientific and strategic use of data.

At present, he is an Assistant Professor of Statistics at the University of the Philippines (UP) Diliman, from which he obtained his Master of Science in Statistics and Bachelor of Science in Electronics and Communications Engineering. He is also the current Director for Research of UP School of Statistics, and the School's Director for Extension Services and External Linkages from 2022 to 2023. Additionally, he serves as the Project Leader of the UP Rainbow Research Hub, a pioneering collaboration among academic, professional, and advocacy institutions that seeks to make a difference for the LGBTQI community in the Philippines through better LGBTQI scholarship and research.

Prior to joining the faculty of UP, he served as the National Consultant on HIV and LGBTI of the United Nations Development Programme (UNDP) in the Philippines and worked with the country's multi-agency UN Joint Team on AIDS and UNDP in Asia and the Pacific. He has also been formally engaged by various government and non-government institutions, such as the Commission on Human Rights of the Philippines and civil society organisations working on LGBTQI and human rights issues.

He has been involved in various research and development projects funded by the Department of Science and Technology of the Philippines, UP Population Institute, UNDP, Joint United Nations Programme on HIV and AIDS, and United States Agency for International Development. As of 2022, he has raised and managed Php 24.8 million (USD 470,000) for research and development projects on HIV and LGBTI. He has also led and completed research projects with grants totaling Php 4.1 million (USD 73,000).

His research works have been published in several statistics journals such as The Philippine Statistician, and Communications in Statistics - Simulation and Computation. His research direction is on computational statistics, social research methods, and applied social statistics, with focus on digital data and data on gender, sexuality, and human rights.

He has been a licensed engineer in the Philippines since 2018.
