    Leo Wanner is working in the field of computational linguistics, teaching the computer to understand spoken and written natural language material,  to supply people with information that might be useful to them and to interact with people. His research areas include human-computer interaction (in particular, the design and realization of conversation agents that reveal social and cultural competence), automatic written and spoken graph transduction-based language generation, automatic summarization of written material, data-driven parsing, information extraction, and, more recently, profiling of authors of written material and the information structure-prosody interface. He is furthermore interested in lexicology and lexicography, and there, in particular, in the automatic recognition, representation and use of lexical idiosyncrasies (so-called "collocations") by both native speakers and learners of a language. An important characteristics of his research is that it is multilingual.

    My interests lie in moral and political philosophy and practical rationality, as well as intersecting areas in economics and political science. I am especially interested in issues of distributive justice, including ones arising across states and generations. I explore how egalitarian distributive principles  should guide the design of social institutions that shape the prospects of children, parents, the elderly, and future generations. My current work focuses on how we should deal with the needs of the elderly and with variations in lifespan.

    I work on quantum information, especially quantum Shannon theory, which aims at incorporating information-theoretic ideas into physics. The Shannon theoretic approach has succeeded in quantifying entanglement as a resource in information processing task, and likewise for other properties of quantum systems such as channel and storage capacities of quantum systems. One of my favourite topics is the interplay between classical and quantum information, evident in the intricate structure of local operations in composite systems, such as data hiding or "information locking". I also work on additivity and non-additivity of quantum channel capacities, quantum data compression, and zero-error quantum communication. Further interests include statistical mechanics, thermodynamics, resource theories, entropy characterization and entanglement measures. But at heart I am a mathematician and will still get fascinated by classic problems: existence of Hadamard matrices, incompleteness, ...

    The keyword is behaviour of fluids at nano-scale. I study the transfer of ions and water molecules through nano-metric (tens of nanometers) barrier layers of composite nanofiltration membranes. Another example is the transfer of ions and water through nano-porous track-etched membranes having identical cylindrical pores. I also study processes of current-induced concentration polarization of nano-/micro-interfaces where concentration polarization is strongly-coupled to electroosmosis and fine separation of solutes like peptides can occur. Recently, I discovered that a layered structure consisting of a micro-perforated ion-exchange membrane and a nanoporous layer can have very interesting properties useful for AC electroosmotic pumping . Another topic is experimental and theoretical studies of ion transfer across polyelectrolyte multilayers where we have recently discovered very high (>1000) selectivities in the electrically-driven transfer of ions of different charge magnitudes.

    My research focuses in three areas each of which has generated several authored and edited books and journals special issues. These areas are political, social, and aesthetic Continental philosophy. I study each of these following the hermeneutic principle according to which Being is not an objective entity that philosophy must describe but rather the effect of interpretations. Following the work of Hans-Georg Gadamer, Gianni Vattimo, and Richard Rorty, I emphasize the ontological and political nature of hermeneutics in order to demonstrate the danger of dogmatic beliefs for religious and political practices. The problems of education and emergency have been at the center of my research these past years in relation to politics, society, and art. My next books and essays will explore “fake news” and “post-truth” in this so-called age of alternative facts to argue, as Bruno Latour said, that "facts remain robust only when they are supported by a common culture, by institutions that can be trusted, by a more or less decent public life, by more or less reliable media.”

    The Middle-to-Upper Paleolithic transition has been the focus of my research for the last 20 years, leading to fieldwork at several sites: (a) the Lagar Velho rock-shelter (Portugal) and its burial of an early modern human child with diagnostic Neandertal features (evidence for interbreeding at the time of Neandertal/modern contact); (b) the Almonda karst system (Portugal), whose archeology spans half-a-million years and includes such important fossils as the 400,000 year-old Aroeira 3 cranium; (c) the Pestera cu Oase (Romania), site of Europe's oldest modern humans; (d) Cueva Antón and Cueva de los Aviones (Murcia, Spain), with the earliest known use of personal ornaments, 115,000 years ago; (e) several caves in Iberia, France and Italy where U-Th dating of associated speleothems showed rock art to be >65,000 years old. These early artists were Neandertals, whose behavioral modernity and late persistence to the south of the Ebro drainage remain my main areas of interest.
