News:
- The Monday meetings of the Algorithms Group are taking place this term on Tuesdays and online. If you would like to participate, write me an email, so I can send you an invitation.
- My student hours take place every Wed 10.00-12.00, either in person or via zoom, currently only by appointment (due to the coronavirus emergency). Please send me an email if you would like to talk to me.
- If you are interested in prefix normal words, there have been recent advances, see our latest paper accepted at Theoretical Computer Science (preprint see here). Here is a short (updated!) writeup on open problems on prefix normal words.
Research Interests
I work on string algorithms and other discrete and algorithmic problems, mostly arising in bioinformatics applications. In algorithmic bioinformatics, I have mostly worked on mass spectrometry data interpretation (genomics, proteomics, metabolomics) and on string distance measures for expression clustering (transcriptomics), but am interested in all algorithmic and combinatorial problems on discrete structures (strings, sequences, trees, graphs) arising in the context of biological applications.
Brief Vita
I am associate professor at the University of Verona, and have been working here since November 2011. I got my first degree (Diplom Mathematik) from Freie Universität in Berlin, Germany, and my PhD (in Computer Science) from Bielefeld University, Germany. My PhD thesis treated algorithmic problems in Mass Spectrometry, and was supervised by Sebastian Böcker (now in Jena, Germany). I have worked as a research assistant at ETH Zurich, Switzerland; as a research assistant and later postdoc at Bielefeld University, Germany; and as a postdoc at Salerno University, Italy, where I had a Marie Curie IEF fellowship. In addition, I have spent time as a visiting researcher at the following scientific institutions: Rényi Institute, Budapest (Hungary); the University of the Witwatersrand, Johannesburg (South Africa); and at SANBI, Cape Town (South Africa).
I am member of the Bioinformatics and Natural Computing Group at the Department of Computer Science of Verona University. We organized the international conference IWOCA 2015 (26th International Workshop on Combinatorial Algorithms), of which I was PC co-chair (with Bill Smyth) and OC chair; as well as the 11th StringMasters, an international workshop on string algorithms (with Giuditta Franco). I am also member of the Center for Biomedical Computing (CBMC) in Verona, and of the Centre for Combinatorics on Words and Applications (CCWA) at Murdoch University, Perth, Australia.
There is a (usually somewhat outdated) CV on my institutional page.
