I have a background in epidemiology and public health.
As a statistician, I possess a thorough understanding of data management and statistical modeling methodologies. My expertise encompasses a spectrum of techniques, including multistage biosystems, latent class models, survival models, generalized estimating equations, and marginal structural models. Furthermore, as an epidemiologist, I am committed to utilizing observational databases to effectively measure relavant variables, assess associations, and make inferences on both sampled and unsampled study populations.
I have experience in study design, including the development of appropriate research questions, sample size calculation and selection of the most appropriate study design to answer the research questions. I also have experience in collaborating with clinicians to provide the best results in clinical trials and observational studies. At present, I am actively engaged in collaboration with Matteo and other esteemed colleagues on multiple research projects.
