Hallo! My name is Vanni Noferini, I am originally from Florence, Italy, and I am a Lecturer in the Department of Mathematical Sciences at the University of Essex. My research interests are in matrix theory, numerical linear algebra, numerical analysis, complex network analysis, and related topics.

More specifically my interests include matrix polynomials, linearizations, matrix functions, matrix equations, polynomial eigenvalue problems, polynomial root-finding, nonlinear root-finding, structured linear algebra problems, stability of algorithms (or lack thereof), and complex network analysis. Before moving to Essex I got an M.Sc. in Physics at the University of Florence (Italy) under the supervision of Filippo Colomo. I then obtained my Ph.D. in Mathematics at the University of Pisa (Italy), working with Dario Bini and Luca Gemignani. In 2012 I moved from Italy to the United Kingdom, and I have been a postdoctoral Research Associate in the Numerical Analysis Group at the University of Manchester (UK), where I worked with with Nick Higham. From 2012 to 2014 I also have organised the Manchester NASC seminars.

I joined the Universtiy of Essex in September 2015. Here I am part of two out of the five local research groups, namely, the Applied Mathematics group (led by Hadi Susanto) and the Pure Mathematics group (led by Gerald Williams).

My Erdös number is currently equal to 4.


My research page will tell you more about my work, including publications, preprints, and coauthors.


On my teaching page you can find more about my courses and my students.


Since September 2016 I am serving as Director of First Year Undergraduate Studies and Undergraduate Recruitment Director for the Department of Mathematical Sciences at Essex.

I am the one on the right and am meeting my two coauthors Yuji Nakatsukasa (left) and Pafnuty (centre); the picture on the right shows me (left) in 2017 having Turkish coffee with coauthor Bahar Arslan (right) in Izmir, Turkey:
