John W. Creswell, PhD, has been a professor of educational psychology at the University of Nebraska-Lincoln since 1978. In addition to teaching at the university, he has authored numerous articles on mixed methods research, qualitative methodology, and general research design and 12 books, many of which focus on types of research designs, comparisons of different qualitative methodologies, and the nature and use of mixed methods research. His books are translated into many languages and used around the world. For the last five years, Dr. Creswell served as a co-director at the Office of Qualitative and Mixed Methods Research at the University of Nebraska, which provided support for scholars incorporating qualitative and mixed methods research into projects for extramural funding. He served as the founding co-editor of the Sage Journal of Mixed Methods Research, and as an adjunct professor of family medicine at the University of Michigan where he assisted investigators in the health sciences and education with research methodology for National Institutes of Health (NIH) and National Science Foundation projects. He also served extensively as a consultant in the health services research area for the U.S. Department of Veterans Affairs. Dr. Creswell was a Senior Fulbright Scholar to South Africa and in 2008 lectured to faculty at five universities on education and the health sciences. In 2012 he served as a Senior Fulbright Scholar to Thailand. Recently he served as a co-leader of a national working group developing guidelines for mixed methods research for NIH. He lives with his wife, Karen, in Lincoln, Nebraska. Vicki L. Plano Clark (Ph.D., University of Nebraska-Lincoln) is an assistant professor in the Quantitative and Mixed Methods Research Methodologies concentration of Educational Studies at the University of Cincinnati. Her teaching focuses on foundations of research methodologies and mixed methods research, including a two-semester mixed methods sequence and special topics courses. As a methodologist specializing in mixed methods research, her scholarship aims to delineate useful designs for conducting mixed methods research, examine procedural issues associated with these designs, and consider larger questions about the contexts for the adoption and use of mixed methods. She has also co-authored several books with John W. Creswell including Designing and Conducting Mixed Methods Research (SAGE, 2007, 2011), The Mixed Methods Reader (SAGE, 2008), and Understanding Research: A Consumer's Guide (Pearson Education, 2010, 2015). She was the founding Managing Editor for the Journal of Mixed Methods Research and currently serves as an Associate Editor. In 2011, she co-led the development of Best Practices for Mixed Methods in the Health Sciences for NIH's Office of Behavioral and Social Sciences Research. She is a founding co-editor of SAGE's Mixed Methods Research Series. As an applied research methodologist, Vicki also engages in research and evaluation projects on a wide array of topics such as the management of cancer pain, the identity development of STEM graduate students, the professional development of teachers of Chinese, and the effectiveness of school reform initiatives. Before joining the University of Cincinnati, she was the director of the Office of Qualitative and Mixed Methods Research, a service and research unit that provides methodological support for proposal development and funded projects at the University of Nebraska-Lincoln. Originally trained in physics, she spent 12 years developing innovative curricular materials for introductory physics as the Physics Laboratory Manager at the University of Nebraska-Lincoln.
