I am an Assistant Professor in the School of Information at the Florida State University (Florida's iSchool) and a Core Affiliate of the Institute for Successful Longevity. I also hold a courtesy appointment with the Department of Computer Science. I am an Associate Editor of BMC Medical Informatics and Decision Making.
My research lies in biomedical and health informatics, clinical research informatics, knowledge discovery, knowledge representation, and ontology-enhanced data analytics. At FSU, I lead the eHealth Lab. The overarching goal of our research is to improve the population health and advance biomedical research through the collection, analysis, and application of electronic health data from heterogeneous sources. On the foundational track, we develop semantic and structural methods to enhance controlled terminologies/ontologies and improve their utility in natural language processing, clinical decision support, data analytics, and electronic health records. On the application track, we devise novel data-driven methods and tools to assess the generalizability of clinical studies using the electronic data in clinical trial registries, public patient databases, and clinical data warehouses. Our research aims to improve the representation of underserved population subgroups in clinical studies such as older adults with multiple chronic conditions. Another line of our research is to bridge the terminology gap between health information consumers and health professionals through the analysis of the textual content in the online social media. Our research has been funded by National Institutes of Health, Amazon, NVIDIA, FSU Council on Research and Creativity, and Institute for Successful Longevity.
Before joining FSU in Fall 2015, I was a Postdoctoral Research Scientist in the Department of Biomedical informatics at Columbia University between 2014 and 2015, working with Dr. Chunhua Weng. In my postdoctoral research, I developed informatics methods to assess the collective population representativeness of clinical studies, with the goal of improving the transparency of study generalizability to the real-world population. I received my Ph.D. in Computer Science at New Jersey Institute of Technology in 2014, where I worked with Dr. James Geller and Dr. Yehoshua Perl in the Structural Analysis of Biomedical Ontologies Center (SABOC). My doctoral thesis is centered on quality assurance methodologies for controlled biomedical vocabularies - Unified Medical Language System (UMLS), SNOMED CT, and domain ontologies in BioPortal. My postdoctoral and doctoral research was supported by three R01 grants funded by the National Library of Medicine and Columbia's CTSA grant funded by the National Center for Advancing Translational Sciences.
I have published over 50 peer-reviewed articles (41 in PubMed) in leading biomedical informatics venues, including Journal of Biomedical Informatics, Journal of Medical Internet Research, BMC Medical Informatics and Decision Making, Artificial Intelligence in Medicine, Methods of Information in Medicine, American Medical Informatics Association (AMIA) Annual Symposium, and MEDINFO. My first-author papers received many prestigious recognitions in the field of biomedical informatics, including (1) two Distinguished Paper Awards of AMIA Annual Symposiums (AMIA 2015 paper and AMIA 2017 paper), (2) paper selection in "AMIA 2014 Informatics Year In Review" (AMIA 2013 paper), (3) Finalists of the Student Paper Award of AMIA 2015 Summit on Clinical Research Informatics and MEDINFO 2015, and (4) paper selection in "Clinical Research Informatics 2016 Year in Review" (JBI 2016 and AMIA 2015 paper)
In 2014, I was inducted into Alpha Epsilon Lambda National Graduate and Professional Honor Society. I received my MS from Columbia University and BS from Beijing University of Posts and Telecommunications, both in Computer Science.
In my spare time, I am interested in photography and traveling. This is my Photography Studio.
