About

Hallo! My name is Vanni Noferini, I am originally from Florence, Italy, and I am an Associate Professor in the Department of Mathematics and Sytems Analysis at Aalto University. 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 and their applications, stability of algorithms (or lack thereof), the theory of conditioning and the practice of estimating it, and complex network analysis. Before moving to Aalto 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. Between 2015 and 2019 I held my first permanent academic job, being a Lecturer in Mathematics at the Department of Mathematical Sciences within the University of Essex (UK).

I moved to Finland in April 2019, to be employed by Aalto as an Associate Professor. Here I am part of the Applied Mathematics group, and I also share several research interests with colleagues in the Algebra and Discrete Mathematics group.

My Erdös number is currently equal to 4.

The picture below on the left was taken by my coauthor Alex Townsend in 2014 in Tokyo, Japan. 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:

And here is a photograph of (part of) my research group taken in 2021. From left to right are María del Carmen Quintana Ponce , Giovanni Barbarino and Paul Van Dooren enjoying world-famous Finnish pizzas (and fried crickets).
