I am a Ph.D. candidate in Computer Science working with Peter J. Haas and the DREAM Lab at at the University of Massachusetts Amherst. I am also collaborating with the Human Data (HuDa) Interaction Lab at NYU Abu Dhabi.
My research focuses on augmenting data management systems to better support data science, all stages of analytics, with special emphasis on predictive and prescriptive analytics, and faster and easier decision making. The main goal of my research is to democratize data science and decision making in a variety of practical applications, across different disciplines and industries. In my research conducted so far, I built complete and efficient data management systems able to support a broad class of decision-making problems that can be expressed as integer linear programs (ILP), on both certain and uncertain data. My current and future research aims at enlarging the scope of these systems to even broader classes of problems. Given the complexity and the broad scope of my research endeavors, my work has been largely interdisciplinary, it led to several top-tier publications, spanning also other research areas such as natural language processing, information retrieval, text summarization, AI, and robotics, and has been recognized by several ACM awards.
Prior to joining UMass, I received my Bachelor's and Master's degrees in Computer Science from the Computer Science and Engineering Department at the University of Bologna, Italy.
During summer 2017, I interned at Microsoft Research, in the Data Management, Exploration and Mining (DMX) group. During summer 2016, I interned at IBM Watson. During spring 2016, I visited NYU Abu Dhabi, UAE. During summer 2015, I visited the AMPLab at the University of California, Berkeley. During my Master's studies, I visited the Data-Intensive Systems group at Aarhus University, Denmark. During my Bachelor's studies, I interned in the Database Lab at the University of California, Riverside.
