About Me
- Name: Charles Assaad
- Address: Paris, France
I am curretly a Junior Professor & Inserm Chair at the Pierre Louis Institute of Epidemiology and Public Health (IPLESP) - Inserm and Sorbonne Université. I am leading the CIPHOD team which is specialized in causal inference in public health using large observational health databases.
My work focuses mainly on developing new theories and methodologies to assist epidemiologists in uncovering and estimating causal effects from observational temporal data, as well as identifying root causes of anoamlies, especially in the presence of high-level background knowledge (abstractions). It's an exciting research area with lots of open questions! More generally here's a non exaustive list of topics that I am interested about:
- Causal Discovery
- Causal Reasoning
- Root Cause Analysis
- History of Causation
- Machine Learning
- Time Series Analysis
- Information Theory
Applications:
- Epidemiology
- IT monitoring
- Ecology

Projects
(2023-2028) PEPR Project: CAUSALIty Teams up with Artificial Intelligence (CAUSALI-T-AI). This project aims to address various challenges in causal modeling using advanced machine learning techniques. It focuses on four main directions: Stable causal modeling; Learning causal representations; Domain adaptation; and Causal learning in uncertain environments. Link
(2021-2023) R&D Booster Project: Causal System for Problem Resolution (CSPR). This project aims to develop an intelligent engine for monitoring systems that uses a known causal graph as well as the do-calculus to transform whenever it is possible a causal question into a statistical expression that can be directly estimated from observational data.
