Marion Nicole Marie Dénos
About
I am a researcher in medicine and health sciences. My research expertise includes epidemiology, genetic epidemiology, use of metabolomics data, applied statistical modeling, study design and causal inference.
My research covers different topics, exploring causal relationships between lifestyle factors and various phenotypes or diseases, including cancer and cognitive function.
I have analytical skills in biostatistics, with experience using both Stata and R.
