**Position/Role**

Reader (Associate Professor) in Applied Mathematics and Head of the Complex Systems and Networks group at Queen Mary University of London, UK

Turing Fellow at the Alan Turing Institute, London UK

**Professional career**

In 1998 Ginestra Bianconi obtained a Laurea in Physics (equivalent to BSc and MSc) at the University of Rome “La Sapienza” and in 2002 she obtained a PhD in Physics at University of Notre Dame, Indiana, USA. She has worked as Postdoctoral Research Associate at the Université de Fribourg, Fribourg, CH (from 2002 to 2003) and at the International Center for Theoretical Physics (ICTP), Trieste, Italy (from 2003 to 2009). In 2009 she was appointed Assistant Professor in the Department of Physics at Northeastern University, Boston, USA. In 2013 she joined the School of Mathematical Sciences at Queen Mary University of London (QMUL), London, UK where since 2015 she is Reader in Applied Mathematics. In 2018 she has been appointed Alan Turing Fellow at the Alan Turing Institute and Head of the Complex Systems and Networks group at QMUL.

**Scientific results**

Ginestra Bianconi’s research focuses on Network Theory,Applied Mathematics and Statistical Mechanics applied to Complex Systems. Networks describe the rich underlying structure of Complex Systems and are formed by the set of elements of the system (nodes) and the interactions among them (links). The most prominent examples of complex networks include the brain and social networks.

Ginestra Bianconi’s research activity in Network Theory is motivated by the urgent need to develop theoretical approaches that address the challenges posed by the complexity of real networks using innovative approaches at the frontier between Applied Mathematics and Statistical Mechanics. Among her most relevant results we mention the Bianconi-Barabási model. This model explains how networks such as the Internet or the World-Wide-Web evolve by establishing a map between the network evolution and the Bose-Einstein condensation, a quantum phenomenon occurring in a gas of Bose particles. Another notable research line of Ginestra Bianconi is the formulation of an information theory of networks based on entropy of network ensembles that can be used to solve inference problems. Recently the research activity of Ginestra Bianconi has focused on multilayer networks that describe systems formed by several interacting networks and on network geometry. Additonally, Ginestra Bianconi has several interdisciplinary collaborations with scientists in neuroscience and informatics and with economists.

**Scientific results**

The field of interest of Luisa Donatella Marini is, generally speaking, the analysis of numerical schemes for the solution of elliptic partial differential equations (of second and fourth order) by means of different kinds of finite element methods: conforming, non-conforming, hybrid, mixed, and equilibrium. More specifically, she applied finite element techniques for the treatment of problems coming from various applications: semiconductor device simulation, electromagnetism, fluid-dynamics, structural mechanics. Particular emphasis was given to the approximation of non-coercive problems, which lead to develop various techniques for stabilizing Galerkin formulations, for applications to domain decomposition methods with non-matching grids, and to advection dominated problems. In the last decade she was particularly interested in developing and analyzing schemes based on Discontinuous Galerkin methods, for the discretization of various applied problems, such as Darcy flows, advection-diffusion problems, and Reissner-Mindlin model for plate problems. The more recent production is devoted to a new technique, the Virtual Element Method, for the discretization of Pde's with applications.

With her team he defined an index that makes it possible to easily calculate the territorial effect of sensitivity to desertification in order to exceed the international protocol limit "Mediterranean Mediterranean Desertification And Land Use European" (MEDALUS), which does not provide an estimate of sensitivity to the desertification of a territorial area (municipal, provincial, regional, hydrographic area) through a single value. This index has significant advantages, because it produces effective rankings, with the consequent possibility of processing comparative data in relation to different time periods.

Within the scope of this research in mathematics applied to the protection of the environment, the effects of the impact of the transport of Saharan dust on particulate matter (PM10) are studied.

The results of these researches have been exhibited in international conferences in all 5 continents, of which about 20 organized by her in Europe and the USA, being part of scientific committees in which she was sometimes the only Italian member. She has held seminars in numerous Italian and foreign universities, being, by way of example only: guest of research groups, invited guest on the occasion of intensive semesters of the National Institute of High Mathematics (INDAM), guest of the "Mathematics Research Center E. De Giorgi "of the" Scuola Normale Superiore "of Pisa, of the" Newton Institute "of Cambridge, of the Department of Mathematics of the" Research Melbourne Institute of Technology "of Melbourne, of the" Tokyo University of Science "of Tokyo, of the" Florida Institute of Technology "of Miami, of the Department of Mathematics, of the" Harvard University "of Boston, of the" Mittag-Leffler "Institute of the Swedish Royal Academy of Sciences in Stockholm.

**Scientific results**

The research activity of Maria Grazia Speranza is oriented to the study of mixed integer mathematical programming models, that is optimization models where a function is minimized or maximized subject to constraints and the variables must take integer values. Such models have been applied to several problems, in particular in the area of finance, where the decision concerns the investment of a capital in securities with the objective of minimizing the risk while guaranteeing a given average rate of return, and to the area of transportation and logistics where location or distribution decisions must be taken with the objective of minimizing the costs while guaranteeing a given service level. Most recent research concerns the value of collaboration and shared mobility.
