Introduction

Promoting Healthy Aging through Semantic Enrichment of Solitude Research (PHASES) unites two historically separate literatures — solitude and gerotranscendence — to better understand how time spent alone in later life contributes to either flourishing or decline. While solitude is often linked to loneliness and negative health outcomes, gerotranscendence emphasizes the potential for growth, meaning, and psychological well-being in older age.
PHASES will bridge these perspectives by developing interoperable ontologies — the Solitude Ontology and Gerotranscendence Ontology — grounded in the Behavior Change Intervention Ontology and Open Biological and Biomedical Ontologies standards. These ontologies will underpin a public web portal integrating data from the National Library of Medicine and Open Science Foundation, featuring a recommender system and question-answer interface to support cross-disciplinary discovery.
Led by experts from the University at Buffalo, University of Florida, and University of Michigan, PHASES will train stakeholders to use this infrastructure, foster integrative research on solitude and aging, and promote data-driven insights into how being alone can support healthy aging.

John Beverley, PhD, University at Buffalo, johnbeve@buffalo.edu

Assistant Professor at the University at Buffalo and Co-Director of the National Center for Ontological Research. He works at the intersection of ontology, formal logic, machine learning, and knowledge graph engineering, with applications in infectious diseases, ethics in health, and applied epistemology.

He holds a Ph.D. in Philosophy from Northwestern University and worked as a senior ontologist at the Johns Hopkins Applied Physics Laboratory. He has contributed to projects such as the Infectious Disease Ontology and works on the Basic Formal Ontology (BFO, ISO/IEC 21838-2).

Bill Duncan

MPI

William Duncan, PhD, University of Florida

Duncan brings more than 15 years of experience developing and using biomedical ontologies for health informatics, as well as computer programming.

These ontologies are used to harmonize diverse biomedical and biological data sources (such as dentistry, environmental metagenomics, and cancer data), detect inconsistencies, and gain new insights through the application of automated reasoning.
