    Leticia Tarruell leads the Ultracold Quantum Gases experimental group at ICFO, which uses ultracold (nanokelvin) atomic gases as model systems to explore fundamental phenomena in quantum many-body physics. By exploiting atom-light interactions, the group engineers highly controllable artificial quantum materials and probes their properties. The goal is to employ these systems as quantum simulators (i.e. special purpose quantum computers) for studying open problems in various fields of physics, in particular in the condensed-matter context, and for realizing novel quantum phases of matter. This research is carried out in three different platforms: quantum mixtures in the continuum, ground state atoms in optical lattices, and arrays of atoms in Rydberg states.

    My research is focused on comparing and understanding the similarities and differences between human, animal and machine minds. At the heart of my research program is an experimental framework I term the signature testing approach (Taylor et al. 2022). This uses the information processing errors, biases and other patterns agent exhibits to make inference about the content of different minds. This approach generates powerful intelligence tests that strongly constrain the possible cognition an agent is using and allows for the comparison of both biological and artificial intelligences. I also have a keen interest in understanding the role information processing errors and biases play in human decision-making. My lab currently works with a wide range of study species, including the kea parrot, rats, and adult humans.

    My main research areas are Fourier Analysis and Approximation Theory. Particularly, I study the relationship between "smoothness" of a function and the possibility to approximate or to represent this function by a sum of "simple" functions. The case when "simple" functions have wave structure is of special interest.

    My studies are raising the question about the geographical, linguistic, religious, cultural and mental borders of the multi-layered legacy in the centres and peripheries of the Medieval Worlds. I have analyzed the Europe-wide intellectual attraction and radiance of the Parisian abbey of Saint-Victor in the mirror of its exegetical and theological production, focusing on the various European areas. Then, I have broadened my panorama to reconstruct European religious and intellectual identities by conducting extensive research on texts of Christian-Muslim encounters and perceptions in Europe, specializing on early Christian polemics against Islam, the linguistic and religious borders between Christians, Jews and Muslims, processes of religious and cultural passages, entanglement and dis/integration among the members of the three monotheisms in the Carolingian and Iberian Worlds. A new research field I try to establish is methodologically sound Transcultural Studies and Palaeography.

    I work in mathematical analysis. My research deals with harmonic analysis, geometric measure theory, and elliptic PDE's. Particularly, I am interested in the relationship between analytic notions such as analytic capacity or harmonic measure, and geometric concepts like rectifiability. In a sense, analytic capacity measures how much a set in the plane is visible or invisible for analytic functions. On the other hand, rectifiability tells you if a set is contained in a countable collection of curves with finite length. Around 2002 I proved that analytic capacity is semiadditive. This was an open problem since the early 1960s. Later on I studied related problems in higher dimensions. In particular, in a collaboration with F. Nazarov and A. Volberg I have proved the so called David-Semmes conjecture in the codimension 1 case. This result has important applications to the study of harmonic measure and the Dirichlet problem for the Laplace equation, which are other main interests.

    My goal in philosophy has long been the same: to explore the nature of the mind within a naturalistic framework. What is most distinctive of my research is my ongoing effort to respect scientific findings about mental phenomena while insisting on the critical importance of the method of analysis and the theoretical tools provided by analytic philosophy. My current research focuses on the analysis of central topics in the philosophy of mind and the philosophy of cognitive science, with a special emphasis on the philosophy of perception and rationally responsive unconscious mental states such as implicit attitudes.
