Applications are invited for several postdoctoral researcher positions in the Department of Software Science at Taltech (Tallinn University of Technology) working with Pawel Sobocinski on compositionality and applied category theory. Compositionality describes and quantifies how compound systems can be assembled out of their constituent parts in a way that respects the underlying semantics. Compositional design is necessary for trustworthy software and leads to the development of correct and efficient data structures and algorithms. The inter-disciplinary group will work on compositional approaches to various application domains, including models of concurrency, control theory and cyber-physical systems, game theory, relational algebra and database theory, and machine learning. The language and techniques of category theory will serve as a connecting and unifying lingua franca, with an emphasis on the use of string diagrams and diagrammatic reasoning. The group will focus on theoretical as well as practical aspects, including tool development. The project is part of a research measure of the Estonian IT Academy programme, funded by the Estonian state and the European Social Fund. Qualifications -------------- The ideal applicants will have a PhD in Computer Science (or related field), strong background in at least one application area as well as in category theory. Experience in programming and software engineering is also desirable. In addition to research, the successful applicants will be expected to contribute to creating a fertile and exciting intellectual environment, participate and help with the organisation of a weekly seminar with invited external speakers from Europe and overseas, and help in organising and hosting regular international scientific events. There will also be opportunities to recruit and co-supervise masters and doctoral students, interact with local industry and with the general public through outreach activities. Tallinn and Taltech ------------------- Tallinn, a historically important Hansa trading port has its charming old town listed on the UNESCO World Heritage List. In recent years it has become one of the fastest-growing IT hubs and one of the most active startup scenes in Europe. The working languages at Taltech are Estonian and English. Further details and application procedure ----------------------------------------- Compensation will competitive wrt to European standards, and commensurate with experience. The positions will start on a mutually agreeable date from September 2019 and last for two years, with the possibility of an extension. Interested candidates are invited to contact Pawel Sobocinski (pawel@cs.ioc.ee) for any questions. To apply, the candidate should send a CV, a research statement (maximum 3 pages) and the names and contact details of two people who can be contacted for a reference to pawel@cs.ioc.ee by June 21, 2019.
