Short Bio: Dr. Chandra Prakash Yadav is a Principal Biostatistician at Pfizer India, Chennai. At Pfizer, he provides input in design and analysis at different stages of clinical studies, ensures regulatory compliance, and provides statistical expertise for study designs and regulatory submissions. He is part of the RWD/E global team and is working on generating evidence from RWD using advanced causal methods.
Before joining Pfizer, he was a postdoctoral research fellow at the Saw Swee Hock School of Public Health, National University of Singapore (SSHSPH). There, he worked on large-scale observational registries and clinical trials for severe asthma patients, applying statistical methods to handle diverse types of missing data in real-world and clinical datasets. Additionally, he has provided statistical inputs in the developed individualized risk prediction models for severe asthma exacerbations. In addition, he applied an advanced Bayesian network model to uncover the complex prediction pathways among core prognostic risk predictors in predicting severe asthma exacerbations. Further, he employed machine learning and Bayesian techniques to forecast dementia progression within a longitudinal Singapore elderly cohort.
He completed his Ph.D. in Competing Risks Analysis at Banaras Hindu University (BHU), Varanasi, India. His research interests include Competing Risks, Longitudinal Data, Incomplete Data, Censored Data, Bayesian Inference, Causal Inference, and Chronic Disease Modeling.
He is exploring and working on different applied fields in Statistics and Public Health, such as Current Status Data with covariates, Causal Inference using randomized control trials and observational data, and progression of dementia using longitudinal data.
