ATT PEOPLE

Scientific Director

Dr. Janet Marquis is currently the Director and Statistician for the Advanced Techniques and Technology Core. She received a M.S. in computer science and a Ph.D. in educational research from the University of Kansas. She has served as a statistics consultant for the Life Span Institute or the past 17 years. Her special areas of expertise include research design, multivariate analyses including structural equation modeling and multilevel modeling, time-series analysis, and database design.

Co-Director

Dr. Daniel Bontempo is currently the Co-Director and Statistician for the Advanced Techniques and Technology Core. He received a BS in computer science from Loyola University in New Orleans, an MAS in Applied Statistics and a Ph.D. in Human Development from the Pennsylvania State University. His special areas of expertise include longitudinal research design, structural equation modeling, multilevel modeling, aggregate data analyses, and factorial measurement models. Ongoing interests also include IRT measurement models, longitudinal mediation, mixture models, and statistical programming.

Users Committee

The Users Committee is chaired by Dr. Susan Kemper. Dr. Kemper is the Roy A. Roberts Distinguished Professor of Psychology and a Senior Scientist in the Gerontology Center, a component of the Schiefelbusch Life Span Institute (LSI).. Her own research focuses on the assessment of age-related changes to language and communication including studies of language production in healthy elderly adults and individuals with Alzheimer’s dementia and Parkinson’s disease. Her recent work has used structural equation modeling to compare the verbal abilities of young and older adults and mixed modeling to examine group and individual differences in longitudinal changes in language production. Her current project involves the use of dynamic structural equation modeling and time-series analysis to study intra- and inter-individual differences in the dual task costs of language production.
