Tushar joined ScHARR (HEDS section) as a Research Associate (Health Economics and Decision Modelling) in August 2018. Prior to this, he was working as a consultant (Economic Modeller) in a US-based consultancy firm for over three years and was providing modelling support to various global pharmaceutical companies.

By training, he is a post-graduate in Statistics and Computing from Banaras Hindu University (BHU), India and an under-graduate in Mathematics from University of Delhi, India.

He has majorly worked on the following disease areas: oncology (Non-small cell lung cancer, Melanoma, Bladder Cancer, Multiple Myeloma) and Infectious diseases (Rotavirus and Hepatitis-A). He has hands-on-experience of working on various modelling methods, such as transition state Markov modelling, partitioned survival analysis (PartSA), disease transmission dynamic modelling (SIR, SEIR, MSEIR framework) and model calibration (using simulated annealing, and Nelder Mead optimization methods). He also has experience of analysing individual level patient-level data (IPD) using various statistical techniques to estimate parameters for survival models. He has worked on several HTA submissions for various European and Latin American countries. He has knowledge of a variety of tools including Excel (and VBA), Mathematica, R (including R shiny, knitr), SAS, C++, SPSS and CS-Pro.

Professional Activities:

Tushar is currently a member of International Society of Pharmaceutical and Outcome Research (ISPOR) and Health Economics Study group (HESG). Within ScHARR, he is a member of the Modellers Academic Group and Statistical Academic Group. He frequently peer-reviews abstracts for ISPOR conferences.
