Welcome to my website!
I am a postdoctoral researcher in Biostatistics at Harvard T.H. Chan School of Public Health, under the supervision of Dr. Jeff Miller.
I obtained my Ph.D. in Statistical Science at Duke University, in North Carolina. Prior to living in the United States in 2019, I studied Economics at Bocconi University, in Milan, Italy.
I am strongly motivated by application, which serves as a base for developing new statistical methodologies. At Duke, I worked under the supervision of Professor David Dunson within Project LIFEPLAN, an international research group whose aim is to quantify biodiversity across the globe. My current line of work includes Bayesian nonparametric models and factor models, with a strong emphasis on cancer applications and mutational signatures.
