Dr. Monahan is the Director of Biostatistics and Data Management Core of the IU Simon Comprehensive Cancer Center. Dr. Monahan’s independent research is in quantitative psychometrics, including latent dimensionality assessment, item response theory, item bias detection, and generalizability theory for reliability assessment. His collaborative research focuses on behavioral medicine and mental health with applications involving analyses of patient-reported symptoms and quality of life across a wide range of disciplines such as primary care, cancer prevention, aging, dementia, psychiatry, diabetes, and juvenile justice.

Dr. Perkins is the Director of the Biostatistics, Epidemiology, and Research Design Program of the Indiana Clinical and Translational Science Institute. Dr. Perkins’ collaborative interests include all aspects of health services research and quality of life research. Her research interests are in the area of categorical data analysis.

Dr. Kroenke is an internationally respected expert in physical and psychological symptoms. He has led or collaborated on more than 15 clinical trials testing collaborative stepped care approaches to managing pain, depression, anxiety, fatigue, and other symptoms. Dr. Kroenke has developed multiple patient-reported outcome measures which have been translated into more than 100 languages and used globally, including the PHQ-9 depression scale, GAD-7 anxiety scale, PHQ-15 somatization scale, PEG pain scale, and P4 suicidality screener. Dr. Kroenke has received numerous awards for both his research and education activities. In 2018, he was the recipient of the Society of General Internal Medicine’s Robert J. Glaser award, the organization’s highest award. He has mentored more than 35 fellows and junior faculty and has over 450 peer-reviewed research publications.

Ms. Caldwell advises researchers on regulatory matters including IRB and FDA submissions and manages the CTSI clinical research monitoring service, single IRB project management service, and Scientific Review Committee.

Dr. Gao is the Director of Biostatistics and Data Management Core of the Indiana Alzheimer’s Disease Research Center. Dr. Gao’s research interest is in developing statistical methods for the analysis of longitudinal, mixed type data. Her major collaborative areas are in Alzheimer’s Disease and aging research.

Dr. Daggy’s methodological research areas include multivariate modeling of semi-continuous data, latent class models with conditional dependence as applied to the area of record linkage, and joint modeling of medical costs and survival with data from complex surveys. Dr. Daggy’s collaborative research areas include non-pharmacological intervention studies, cancer, and areas in health service research.

Dr. Ren’s research focuses on Bayesian sparse learning, variable selection for high-dimensional data and Bayesian integrative model for multi-omics data. Her major collaborative areas are traumatic brain injury, infectious diseases, genomics and bioinformatics studies.

Dr. Liu’s collaboration areas include oncology, anesthesiology, kidney stones, HIV, and musculoskeletal diseases. His methodological research focuses state space models, functional data analysis, and time series data analysis. He is mostly interested in understanding complex dynamics over time and utilizing them for classification and forecasting.

Dr. Bakoyannis’ methodological research is focused on the nonparametric and semiparametric analysis of complex survival, competing risks, and multistate process data, with a special emphasis on issues commonly arising in biomedical and clinical research, such as missing data, misclassification, and interval censoring. His research interests also include methodology development for precision medicine, and in particular, methods for the estimation of optimal individualized treatment rules. His major collaborative research areas are in HIV/AIDS and cancer.

Dr. Zhao’s research focus is on causal mediation analysis, decomposition methods, multi-view data integration, density object analysis, high-dimensional data analysis, neuroimaging data analysis, and proteomics and metabolomics studies. Dr. Zhao has been involved in research projects on neuroscience and pulmonology. Dr. Zhao is a faculty member of the Indiana Alzheimer's Disease Research Center (IADRC) and a faculty member of the Indiana University School of Medicine Alzheimer’s Disease Drug Discovery Center (ADDDC). Dr. Zhao has collaborations in topics of AD, neurodevelopmental impact of substance exposure/abuse, and neurodevelopmental disorders, such as attention-deficit hyperactivity disorder (ADHD) and autism. Dr. Zhao is leading the Pulmonary Biostatistics Core of a large P01 grant and has been involved in research on asthma, cystic fibrosis (CF), and primary ciliary dyskinesia (PCD).
