Pradipta Ray, Ph D is a computer scientist
by training obtaining his Ph.D. from the School of Computer
Science, Carnegie Mellon working on stochastic processes of
regulatory DNA evolution. From 2010-2016, Pradipta was part of
NIH’s Epigenome Roadmap Project modelling epigenetics and its
transcriptional consequences in human stem cell lines at UT
Dallas. From 2016-2022, he led the creation of the computational
genomics unit at the Center for Advanced Pain Studies at UT
Dallas, working on transcriptome-wide association studies to
identify novel non-opioid drug targets for chronic pain.
Pradipta joined Bristol Myers Squibb as Associate Director of
Data Science in 2022, primarily supporting AI/ML workstreams for
cell therapy drug development. Pradipta’s work has resulted in
over 35 peer-reviewed publications at Cell, Nature, Brain and
other top scientific journals, and his work has been featured on
Nature News, WIRED, New Scientist and Scientific American.
Abstract: Artificial intelligence is increasingly central to drug discovery and clinical development, yet many applications are constrained by limited preclinical evidence and small, heterogeneous clinical trial cohorts. In these settings, naïve application of data-hungry machine learning methods risks overfitting, instability, and misleading inference. A hypothesis-driven statistical foundation driven by targeted hypothesis testing and non-parametric and resampling-based methods can provide robust inference when distributional assumptions are untenable and sample sizes are small. Additionally, bayesian frameworks further offer a natural mechanism to formally encode prior biological knowledge, borrow strength across related studies, and quantify uncertainty through posterior distributions rather than unstable point estimates. Clustering approaches can help uncover latent patient subgroups or biomarker subsets providing confidence in analyses from independent readouts, while probabilistic imputation methods can address missingness so that sample sizes are not reduced more than necessary for multivariate analysis. Regularized and Bayesian classification and regression models, including stratified formulations, enable stable prediction and effect estimation under data scarcity. Importantly, these approaches emphasize interpretability, uncertainty quantification, rigor and reproducibility, aligning with regulatory and scientific expectations.
Luna Zaru is a Director of Biostatistics at
Takeda, where she supports the Gastroenterology and Inflammation
Therapeutic Area, in particular ulcerative colitis and Crohn's
disease. She brings more than 15 years of experience in
biostatistics and data science, primarily within the
pharmaceutical industry, complemented by earlier experience at a
nonprofit cancer center in Jordan.
Dr. Zaru holds a PhD in Mathematics from McGill University and an MSc in Statistics from Rutgers University. Throughout her career, she has contributed to the development and evaluation of innovative therapies by applying rigorous statistical methodologies to clinical research and drug development. Her current research interests center on leveraging data analytics to improve operational efficiency, enhance decision-making, and ensure data quality across clinical development processes.
Shoubhik Mondal is a Director in
AstraZeneca’s Oncology Biometrics. He has over 10 years of
experience as a statistician, primarily focused on designing
oncology trials across different development stages. He earned
his PhD in 2014 from the New Jersey Institute of Technology. His
research interests include survival analysis, adaptive design,
and estimands.
Abstract: Early identification of efficacy or timely discontinuation for futility due to lack of efficacy or safety can markedly improve the efficiency and ethical conduct of clinical trials. Careful planning of interim analyses is therefore a critical component of trial design. In this talk, we will discuss role of statistician’s role in planning interim analyses, review main types of interim analyses, outline widely used decision-making methodologies (including efficacy and futility boundaries and safety monitoring strategies), and illustrate their application with real trial examples.
Dr. Zhenming Shun received his Ph.D. in
Statistics from the University of Chicago and an M.S. in
Mathematics from Peking University. He has built a distinguished
career spanning more than 30 years in the pharmaceutical
industry and academia, specializing in biostatistics, data
management, and clinical drug development.
Dr. Shun is currently Head of Biometrics at Marengo Pharmaceuticals. He has also held senior leadership positions, including Global Head of Biostatistics in Oncology at Sanofi and Vice President, Global Head of Biostatistics and Data Management at Daiichi Sankyo. In these roles, he supported strategic business decisions and led global teams responsible for clinical trial design, statistical analysis, and regulatory submissions. His contributions have enabled multiple successful drug approvals in oncology and cardiology, advancing therapies that have improved patient outcomes worldwide.
Beyond his industry leadership, Dr. Shun has authored influential papers in peer-reviewed journals and presented widely at international conferences.
