Dr. Dulal K. Bhaumik
Professor of Psychiatry, Biostatistics and Bioengineering Director, Biostatistical Research Center
Dulal is a Professor of Psychiatry, Biostatistics and Bioengineering at the University of Illinois at Chicago. He received his BS in Statistics from Calcutta University, his MS in Statistics from the Indian Statistical Institute, and his PhD in the same field from the University of Maryland. Dulal's interests include Statistical Problems in Psychiatry, Environmental Statistics, Biostatistics, Design of Experiments, and Statistical Inferences. Currently he is investigating sample size determination and power computation for brain imaging data.
He has conducted research, taught and published extensively in these areas. Dulal and Professor Robert D Gibbons received the American Statistical Association's W.J. Youden Award in 2002 and 2006 for Inter-laboratory Testing in recognition of the contribution to the analysis of inter-laboratory calibration experiments. In 2009, one of his articles received the Outstanding Statistical Application Award from the American Statistical Association.
In 2008, Dulal was elected a Fellow of the American Statistical Association for his outstanding contributions to the development of Optimal Designs; Construction of Prediction and Tolerance Limits for Environmental Data; Hypotheses Testing for Mental Health Research; Development of Statistical Methodology and Dissemination of Software for Analyzing Functional Magnetic Resonance Imaging (fMRI) Data.
His research has been funded by the National Institute of Mental Health. He is also a co-author of the Wiley book Statistical Methods for Ground Water Monitoring, 2nd Edition.

Environmental Statistics, Statistical Problems in Psychiatry, Biostatistics, Design of Experiments, and Statistical Inferences
Projects:
• Multimodal Fusion of Brain Imaging Data
The complex interactions between different brain structures can be studied by brain imaging methods, as the anatomical and functional properties of these structures can be measured simultaneously. Both diffusion tensor imaging (DTI) and functional magnetic resonance imaging (fMRI) gained popularity as non-invasive imaging tools for the study of the brain and the effects of neurological diseases. The primary goal of this project is to develop statistical approaches for combining structural and functional information in the context of connectivity studies. Further we plan to use machine learning algorithms to explore the ability of the network-based measures to provide diagnostic information for neurological diseases.
• Pattern Recognition and Functional Neuroimaging
Currently there are no known biological measures that can accurately predict future development of psychiatric disorders in individual at-risk. Our goal is to investigate whether machine learning and fMRI/DTI could help to differentiate healthy people from psychiatric disorder people.
• Links to Learning (PI Marc Atkins)
The primary goal of this study is to see whether the experimental intervention will lead to improvement in children's academic performance, behavior at home, and behavior at school relative to the treatment-as-usual in a longitudinal study.
• Predicting and Detecting Drug Name Confusion Errors (PI Bruce Lambert)
The objective of this study is to develop three different types of prediction limits based on (i) mixed-effects logistic regression models, (ii) Poisson Distribution, and (iii) empirical Bayes estimates with a high assurance.
