Iván Tzintzun, Post doctoral researcher

Thomas Pelloquin, senior scientific project manager

Thomas has a research background in Sociology (Sciences Po) and a background in applied economics and econometrics (Panthéon-Sorbonne). At the end of his Master’s degree in Econometrics and Statistics at Paris 1 Panthéon-Sorbonne, he was recruited by the Caisse Nationale d’Assurance Maladie (Accidents de Travail et Maladies Professionnelles). His fields of expertise are related to data processing and analysis, public policy evaluation models, qualitative data collection and processing. Scientific project manager at Hospinnomics since December 2019, he is in charge of different projects on innovative care pricing methods and health technology assessment.

Thomas is working on a thesis in parallel with his activity as project leader, based on publications derived from the projects he is in charge of. The work in progress and already completed at Hospinnomics already allows us to identify the common themes of the papers that will be the subject of this thesis: the dimensions of care pathways – in particular rebundling – and innovative financing methods – in particular risk adjustment – have been at the centre of his activity since his arrival at Hospinnomics in December 2019.  The work carried out for this thesis will focus on the EDS and Booster projects; it will be part of an approach to evaluating public health policies and analysing the ex ante impact of organisational changes or health technologies. The thesis will be carried out in parallel with his activity as project manager.
