SHORT BIOI received a Master degree in Engineering (2000) and a Ph.D. in Computer Science (2004) from the University of Rome Tor Vergata. During my Ph.D. I visited MPII with a Marie-Curie fellowship. After postdoc positions at MPII, University of Rome Sapienza and TU Berlin, in 2007 I joined the University of Rome Tor Vergata as an Assistant Professor. In 2011 I moved to IDSIA, USI-SUPSI, first as a Research Professor and then (from 2019) as a Professor. I made long visits (at least one month) at the University of Bergen (2006), EPFL (2008 and 2009), and at the Simons Institute for the Theory of Computing, Berkeley (2015 and 2016).I'm married with 2 children. Traveling is my second favorite activity. These are the (54) countries that I visited so far: Australia; Austria; Bahamas; Barbados; Belgium; Bosnia-Herzegovina; Canada; Chile; China; Croatia; Cuba; Czech Republic; Denmark, Egypt; Estonia; Finland; France; Germany; Great Britain; Greece; Hungary; Iceland; India; Ireland; Israel; Italy; Japan; Jordan; Latvia; Liechtenstein; Lithuania; Luxemburg; Malta; Monaco; Mongolia; Morocco; Netherlands; Norway; Peru; Poland; Portugal; Russia; San Marino; Seychelles; Slovenia; Spain; Sweden; Switzerland; Tanzania; Thailand; Tunisia; Turkey; USA; Vatican. |
RESEARCH INTERESTSMy research is focused on the design and (mostly theoretical) analysis of algorithms and data structures. My main area of research is approximation algorithms. I am also interested in efficient algorithms and data structures, dynamic algorithms, online algorithms, parameterized algorithms, and distributed algorithms. I currently have 140 publications (45 journals) with 125 coauthors. Among my 90 peer-reviewed conference papers, 38 are CORE A* (STOC, FOCS, SODA, PODC) and 41 are CORE A (ICALP, ESA, IPCO, SOCG, ITCS, APPROX, STACS, CP, WG, ISAAC). According to Google Scholar my papers received over 5500 citations and my H-index is 42. |
