Lab Members


Timothy Whitehead, Ph.D.

Dr. Whitehead obtained in Ph.D. in Chemical Engineering in 2000 from Washington University in St. Louis. For his dissertation, he characterized the use of an hepatocyte bioreactor as a bioartificial liver and for drug metabolism studies. While pursuing his doctoral degree he was also employed at Monsanto Corporation, SLU and WU in St. Louis to commercially develop the bioartificial liver, for which he is the co-inventor on the patent. He joined the Shoghi lab in 2010 to develop isolated tissue systems for biological evaluations of disease mechanisms and imaging applications. He is currently working on adapting the bioartificial liver for imaging PET imaging and biomarker discovery. Tim is also serves as the Lab manager. In his leisure time, he enjoys wood-work, cooking, and playing piano, recorder, baritone ukulele and harmonica.

Sudipta Roy, Ph.D.
Postdoctoral Associate

Dr. Roy obtained his doctorate in Computer Science & Engineering, from Department of Computer Science & Engineering, University of Calcutta. Dr. Roy’s research is focused on developing quantitative imaging techniques to characterize tumor heterogeneity, and use PET and MR image features to assess/predict response to therapy. To validate image features, image features are correlated with pathology.

Kaushik Dutta, Ph.D. candidate
Imaging Science doctorate student

Kaushik is an Imaging Science doctorate student at Washington University in St. Louis. Kaushik received his undergraduate degree specializing in Electronics and Communications Engineering from Heritage Institute of Technology, Kolkata. His current research focuses on developing novel deep learning architecture to solve quantitative imaging problems in PET/MR. He is particularly interested in automatic segmentation, registration and machine learning based quantitative analysis of diseases in preclinical and clinical setting. In his spare time Kaushik enjoys playing soccer, reading historical fiction, listening classic rock and cooking.
