CABAÑA, ALEJANDRA

(anaalejandra.cabana@uab.cat)

 I earned my degree in mathematics from Simón Bolívar University in Venezuela and completed my Ph.D. at Central University of Venezuela, with a research stint at the University of Paris XI through a collaboration between Paris-Sud (now Saclay) and UCV. Following this, I spent three years as a postdoctoral researcher at Universitat de Barcelona, supported by a scholarship from the Spanish Agency for International Cooperation (AECI). Subsequently, I returned to Caracas and joined the Venezuelan Institute for Scientific Research (IVIC), where a significant portion of my career unfolded. In 2003, I migrated to Valladolid, initiating as a visiting professor and later securing a position as an associate professor. Since 2009, I have been associated with the Autonomous University of Barcelona, where I currently serve as the coordinator for the Applied Statistics Degree. My early research focused on developing goodness-of-fit tests based on transformed empirical processes, as introduced in the Annals of Statistics 22 (1994) and Annals of Statistics 24 (1996). In subsequent phases, my work delved into continuous-time ARMA processes and integer time series. While maintaining a consistent interest in model-driven approaches, my current research is driven by the exploration of potential interactions between my theoretical expertise in empirical processes and the applications of Neural Networks, particularly in studying variable importance. I am an Associate Professor at the UAB since 2010; and since then I have been the principal investigator of three funded research projects.
CASTELLANA, NATÀLIA

(natalia.castellana@uab.cat)

My primary field of research is Algebraic Topology, and mainly focused on understanding homotopy properties of p-completed classifying spaces of groups and fusion systems in general by means of p-local group information, where p is a prime. Recently I am also working on understanding cohomological properties by its translation to the stable homotopy theory of geometric cochains, specially the point of view of tensor-triangular geometry.

I have participated in several research programmes (e.g. Mittag-Leffler Insitute, Bernouilli Centre, Max-Planck Institut fur Mathematik, Fields Institute,  Banff International Research Centre, Haussdorff Institute, ICTS Bangalore) and workshops (e.g. Matematisches Forschunginstitut Oberwolfach).

FAGELLA, NÚRIA

(nfagella@ub.edu)
Full professor at UB since 2020. She obtained her Ph.D. in 1995 at Boston University under the supervision of Robert L. Devaney and is now the leader of the research group in Holomorphic Dynamics at UB, working in complex dynamical systems and fractals. She has been awarded an Icrea Academia research distinction for the period 2021-2026 and was a Chern Professor at MSRI (Berkeley) during the spring semester of 2022. Advisor of  five Ph.D. students and several postdoctoral fellows, she was a plenary speaker at more than 70 international conferences, was invited to give courses and seminars at leading institutions and and organized several international events. Jointly with Bodil Branner (DTU, Denmark) she is the author of the book “Quasiconformal surgery in holomorphic dynamics”, Cambridge University Press (2014), and of over  50 research papers in leading journals including Inventiones Mathematicae, Advances in Mathematics, Transactions of the AMS, Proceedings of the LMS or Communications in Mathematical Physics.
Her research interests are mainly in Dynamical Systems, a wide field which connects different areas of mathematics but it also links mathematics to real life problems in many areas of science and technology . Her expertise resides in studying dynamical systems from a complex (as opsosed to real) point of view, an area known as complex dynamics, at the intersection between dynamics, complex analysis and topology. Locating an analyzing different types of invariant objects like stable equilibria of these systems (attracting fixed or periodic obits) and the boundaries of their basins of attraction (often fractals known as Julia sets) is a central problem in dynamics, and is at the core of her research. These fractals present many challenges to researchers in complex analysis, topology, geometry and even number theory. In recent years her focus has been on the global dynamics of Newton’s method, the general theory of meromorphic maps and applications to mathematical biology.
