    Peter Wagner's research is based in comparative historical and political sociology, social and political theory, and sociology of the social sciences. It focuses on the identification and comparative analysis of different forms of social and political modernity and of the historical trajectories of modern societies. In this perspective, the term "modernity" does not signal a single and unique model of social organization, but rather variable interpretations of basic human problématiques in the light of specific historical experiences. It was initially applied to a comparative political sociology of European societies, and subsequently to transformations in the self-understanding of Europe.  Over the past few years, it was elaborated further towards a "world-sociology", focusing on the tensions between struggles for autonomy and persisting forms of domination and exploring current possibilities of progress in the light of historical experiences in different world-regions.

    Leo Wanner is working in the field of computational linguistics, teaching the computer how to understand information, how to supply people with information that might be useful to them and how 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 politics. I am especially interested in issues of distributive justice, including ones arising across states and generations. My current work examines how egalitarian distributive principles should accommodate concerns with risk and with personal and collective choice and responsibility. It also explores how such principles should guide the design of social institutions that shape the prospects of children, parents, the elderly, and future generations.

    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.

    Zabala's research focus in three areas each of which have generated several authored and edited books and Journals: ontology, political philosophy, and aesthetics. All these three areas are studied following the hermeneutic principle according to which truth is not an objective goal that philosophy must submit to, but rather the effect of the conflict of interpretations. Following the work of Martin Heidegger, Hans-Georg Gadamer, and Gianni Vattimo Zabala has emphasized the ontological nature of hermeneutics in order to demonstrate the danger of truth impositions for religious and political emancipation. The problem of emergency has been at the center of his research this past years in relation to politics, society, and art. His next books, essays, and articles will be on the problem of freedom in this age of so called alternative facts to demostrate, once again, how there are no facts, but only interpretations as Nietzsche once said.
