Patricia Ordóñez

University of Maryland Baltimore County
Dr. Patricia Ordóñez-Franco was an Associate Professor in the Computer Science Department at the University of Puerto Rico Río Piedras and thereby fulfilling two lifelong dreams and an unexpected midlife one – living in a Spanish-speaking country, having the opportunity to make a greater difference in the world, and becoming a professor. This fall she joins the Department of Information Systems of the University of Maryland Baltimore County as an Associate Professor. Her research interests are in applying machine learning, data mining, and visualization to multivariate time series analysis, specifically to large repositories of clinical and biological data (now known as Clinical Informatics and Biomedical Data Science), creating a voice programming language (assistive technology), and advocating and working towards high-quality computer and data science education for all. She was the first Latina to graduate with a Ph.D. from the College of Engineering and Information Technology at the University of Maryland Baltimore County and the first female Associate Professor to earn tenure in the Computer Science Department at the University of Puerto Rico Río Piedras (UPRRP). She is a former National Science Foundation Graduate Research Fellow. She is serving as General Chair at the 2022 Tapia Celebration of Diversity in Computing Conference and is a former co-Chair of the Diversity, Equity, and Inclusion Council of the Association of Computing Machinery (ACM). She is the recipient of a Great Minds in STEM 2021 HENAAC Award in Education and the 2021 AccessComputing Building Capacity Award.
