I am a statistician developing methods for the analysis of large, high-dimensional and complex data, and applying such methods in several scientific fields – including contemporary “Omics” sciences, Meteorology and Economics.

I received a Laurea (cum laude) in Statistic and Economic Sciences from the University of Rome La Sapienza (Rome, Italy) and a Ph.D. in Statistics from the University of Minnesota (Minneapolis MN, USA).

At the Sant’Anna School of Advanced Studies (Pisa, Italy) I work in the Institute of Economics. At the Pennsylvania State University (University Park PA, USA) I work in the Department of Statistics; I am also active in the Institute for Genome Sciences (one of the Huck Institutes of the Life Sciences), the Center for Medical Genomics, the Center for Comparative Genomics and Bioinformatics, and I have a courtesy affiliation with the Department of Public Health Sciences.

Other academic institutions where I entertain collaborations and spent time over the years include the MOX laboratory of the Politecnico di Milano (Milan, Italy), the Istituto di Analisi dei Sistemi e Informatica of the CNR (Rome, Italy), the Institute for Pure and Applied Mathematics of UCLA (Los Angeles CA, USA), the Courant Institute of Mathematical Sciences and the Department of Biology of NYU (New York, NY, USA), the International Institute for Applied Systems Analysis (Laxenburg, Austria), and the Santa Fe Institute (Santa Fe NM, USA).

Contributo su Rivista

My interests as a statistician include methods to analyze high-dimensional, complex and potentially under-sampled regression and classification problems (in particular dimension reduction and feature selection methods); computational techniques for the empirical assessment of significance (e.g., re-sampling, perturbation and permutation schemes); latent structure and Markov modeling approaches; and functional data analysis methods.

Most of my applied research occurs at the interface between Statistics and contemporary “Omics” sciences. This work comprises interdisciplinary collaborations with biologists and computer scientists in which large genomic, epigenomic, transcriptomic, metagenomic (microbiomes) and metabolomic data sets are analyzed to investigate various aspects of genome dynamics, evolution and function – and to characterize human diseases.

In other interdisciplinary collaborations, I work on Meteorology applications where clustering and re-sampling techniques are used to improve forecast and delineate structure and lifecycle of tropical storms, and on statistical methods for inference and emulation of agent-based models in Economics.

Over the years, my research has been supported by several awards from U.S. funding agencies such as the NIH (National Institutes of Health) and the NSF (National Science Foundation). I am also a Fellow of the American Statistical Association “for outstanding collaborative work in high throughput biology, contributions to methodology in statistics and bioinformatics, commitment to interdisciplinary research, and leadership in developing training programs at the interface of statistics, computation and the life sciences.”
