About Me

My name is Alessandro, and I am a Data Science Leader at GSK within the Quantitative Sciences Innovation organisation. I am currently based in Stockholm, Sweden.

I am also an affiliated researcher at the Department of Medical Epidemiology and Biostatistics at Karolinska Institutet, a co-chair of the openstatsware working group, and an associate editor for the journal Biostatistics.


I have a background in statistics, holding a PhD in biostatistics from the University of Leicester. Previous to that, I studied biostatistics and experimental statistics at the University of Milano-Bicocca, and statistics and computing technologies at the University of Padua.

My background is mostly methodological, covering the areas of survival analysis, correlated data analysis and multilevel modelling, statistical simulation and computational statistics, research software engineering, and some causal inference here and there. I have extensive data analysis experience in practice, having lead, contributed to, and collaborated on several applied medical research projects over the years. A complete list of my scientific contributions is available on Google Scholar.
