Dr. Yen completed her Master of Science Degree in Medical Informatics at the Oregon Health & Science University (OHSU), and earned her PhD in Nursing from Columbia University, specialized in Nursing Informatics. Before attending Columbia, she worked as a Research Associate in the Drug Effectiveness Review Project (DERP) team at the Center for Evidence-Based Policy at OHSU – one of the most successful systematic review programs in the U.S.

Dr. Yen is a registered nurse with informatics training and research experience especially in the areas of health information technology (HIT) usability evaluation, human computer interaction, time motion study, and systematic reviews. She received the mentor award from the Epsilon Chapter of the Sigma Theta Tau International (STTI) in 2014, which is an Honor Society of Nursing and aims to advance world health and celebrates nursing excellence through scholarship, leadership, and service. In addition, in February 2016, she was selected as an Alliance for Nursing Informatics (ANI) Emerging Leader. She aims to establish an academic-practice partnership in clinical informatics to enhance the translation of clinical informatics research to the clinical setting, and to promote the application of innovative and trending informatics approaches to inform and improve clinical practice, as well as bridge the gap between informatics research and practice.

Dr. Yen’s research goals are to continue working on applied clinical informatics, foster the connection between research and practice, promote informatics training to the next generation of health professions education, and provide a user-friendly HIT environment for clinicians.

Dr. Yen, together with Dr. Lynn (Marilyn) Schallom, is leading the Applied Clinical Informatics Research Program. For more information about the Applied Clinical Informatics Research Program, click here.
