    Electron transfer (ET) and excitation energy transfer (EET) are  important processes in biochemistry and material science. The main area of my research is the development of theoretical and computational tools to explore ET and EET in molecular systems and their application to  biomolecules and organic materials to understand  underlying mechanisms that control the charge and exciton migration in the systems. Semiempirical methods, the development of computer codes and simulation of ET and EET in DNA and related systems are of special interest.

    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 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.

    Key words

    My interests lie in moral and political philosophy and practical rationality, as well as intersecting areas in economics and political science. My research focusses in particular on questions about 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 most recent work examines how we should deal with the needs of the elderly and with variations in lifespan as well as the role that demographic factors should play in our response to climate change.

    My research explores the fundamental building blocks of human language, and how languages differ in their realization. I pursue this research focusing on three empirical domains: traditional grammatical categories, categories belonging to interactional language, and the linguistic profiles in neuro-diverse populations. I do this by using the framework I developed In my 2014 monograph: the Universal Spine Hypothesis according to which the grammar of all languages (including interactional language) are constrained by a set of hierarchically organized universal functions (the spine). The question raised by the language profile of neuro-diverse populations is that it involves a different type of language variation, one in which the spine itself may be affected. Thus, my research links to neighboring fields, including philosophy (referential semantics, pragmatics), sociology (conversation analysis), and psychology (theory of mind).

    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, ...
