The ACP Section at Syddansk Universitet is looking for motivated PhD students to work in the areas of Programming Languages and Formal Methods. You can access the two calls here and here.
The calls are quite open, and the exact topic of research will partly depend on the background of the hired candidates. Personally, I'm looking for people interested in Category Theory and doing programming language foundations in CT. If you're interested, pm me or send me an email at stelios@imada.sdu.dk. Worth noting that there are other CT-minded people in the section; see the full call for more information.
