RESEARCH
I am interested in algorithms and computational complexity, particularly in convex relaxations, discrete and combinatorial optimisation, graph homomorphisms, and submodularity. Most of my work lies at the intersection of the above, namely it is on constraint satisfaction problems (CSP) in its many forms (approximation, counting, decision, optimisation, promise).
From the available courses in Oxford's Department of Computer Science, the relevant courses are Computational Complexity, Advanced Computational Complexity, Probability and Computing, and Combinatorial Optimisation. (I will lecture the last one in MT 2022.)
Get in touch if you are interested in doing an undergraduate project, a master dissertation, or a PhD in algorithms, discrete mathematics, or computational complexity. I'm happy to supervise highly motivated students with a strong background in theoretical computer science and/or (any branch of) mathematics.
I currently serve, among many other roles, as the Director of Teaching.
All my publications are available online.
My short CV is available here.

Trivia
My official first name is Stanislav but I go by Standa /'stʌn.da/, which is a commonly used Czech variant/diminutive of Stanislav.
My last name Živný /'ʒiv.ni:/ has two diacritics called the caron
and acute
accent respectively; this can be achieved in LaTeX by \v{Z}ivn\'{y}.
For various reasons I try to minimise travel but you can always visit me (virtually) in Oxford.
