Faculty of Mathematics
Postdocs at the Faculty of Mathematics at the University of Vienna join a large, international department of more than 300 faculty members—many of them early‑career researchers—forming a lively, active community. The Faculty offers modern facilities, an on‑site library, and a cafeteria. Research spans algebra and number theory; geometry and topology; analysis and PDE; stochastics and probability (including mathematical finance); mathematical physics; didactics of mathematics; and numerical and applied mathematics. Many groups run their own seminars and reading groups, with cross‑institutional links to TU Wien and ISTA. Regular workshops at the Erwin Schrödinger Institute (ESI) and the Wolfgang Pauli Institute (WPI) bring thematic programs and visitors throughout the year. English is the working language in most groups. The Faculty routinely hosts FWF‑ and EU‑funded postdocs (including MSCA/Marie Curie, ESPRIT, and Schrödinger return‑phase fellows) and provides support for proposal preparation and submission.

MATIJA BUCIC
Research Focus
My research is primarily situated in the fields of extremal and probabilistic combinatorics, with a strong focus on applying the powerful ideas from these areas to a diverse range of mathematical problems. The central theme of my research is to understand the structure and limitations of combinatorial objects and to determine the threshold at which certain properties must emerge. While I am happy to work on problems arising from a very wide range of topics, a lot of my recent work involves the use of graph expansion. I am particularly interested in continuing the development of the theory of sublinear expanders and in exploring its applications.
Research environment
I have just joined the University of Vienna and am in the process of building up my own group. There will be two PhD students in the group next year, and I have submitted several large grant applications, which if successful would allow to grow the group even more. We are part of the larger Discrete Mathematics group, consisting of several Professors with large groups. There are also excellent opportunities to collaborate with several groups at ISTA working on similar topics. We are starting up a new Vienna Combinatorics Seminar to bring leading researchers to Vienna.
The Faculty will contribute with travel money for 1.000 euros per year and that the faculty offers office space as well as computers. Additional travel funding may be available through my funds depending on the group size and outcome of grant applications.

VERA FISCHER
Research Focus
My work is in mathematical logic, specifically set theory. Central themes of my research are problems in the set theory of the reals, problems at the intersection of combinatorial set theory, descriptive set theory, and forcing, as well as questions arising in higher Baire spaces. My current projects include the study of combinatorial cardinal characteristics and, more broadly, their spectra in both countable and uncountable settings; problems related to the projective complexity of various combinatorial sets of reals; as well as natural counterparts of these problems in the higher Baire spaces. These studies often require the development of new forcing techniques or building upon existing advanced forcing methods.
Research environment
The mathematical logic group of the University of Vienna is the successor of the Kurt Gödel Research Center and traditionally hosts a large number of postdoctoral fellows and graduate students, creating a very dynamic and well established work environment. The group maintains three regular seminars - weekly research seminars in set theory and model theory respectively, as well as a logic colloquium, featuring talks directed to a broader logic audience. The University offers excellent work conditions: ample office space, computer equipment and excellent library facilities.
Expectations towards postdoctoral fellows in this programme
Postdoctoral fellows are expected to maintain an active research program, collaborate with current members of the group, and participate actively in the group’s research activities.

OLIVER HAHN
Research Focus
The Data Science in Astrophysics & Cosmology Group tackles fundamental questions about the Universe's structure, dark matter, dark energy, inflation, as well as galaxy formation through computational, theoretical and data-driven approaches. Our group's research spans three broad areas: developing and running large-scale cosmological simulations to model structure formation from the early Universe to today; advancing the mathematical and computational frameworks underlying perturbation theory and simulation techniques; and applying machine learning to cosmological and astrophysical modelling, inference, and data analysis.
Our group welcomes researchers across the computational cosmology and astrophysics spectrum - from those developing novel numerical methods and theoretical frameworks to those applying simulations and AI to understand observational data from space missions or ground-based telescopes.
Research environment
Our group currently consists of 4 postdocs, 4 PhD students, as well as 7 associated MSc students. We have access to the Austrian VSC5 and MUSICA supercomputing facilities with state-of-the art GPU capabilities for simulations and machine learning applications. All members of the group regularly participate in our weekly group meetings to discuss ongoing research in the group, as well as our weekly journal club. Postdocs are typically supervising their own proposed MSc projects and contribute to the supervision of PhD students. In addition, the group self-organises various social activities to foster integration and group spirit. We also regularly host international guests jointly invited by the group members.
Expectations towards postdoctoral fellows in this programme
A postdoctoral researcher joining the group should have a clear vision for their own research agenda and be ready to create synergies and internal collaborations that benefit both their work and the group's broader research goals. In addition to carrying out their own research, we expect all group members to participate and contribute actively in the regular group activities (such as the group meeting and the journal club), as well as propose and supervise BSc and MSc research projects.
Possible research themes or topics for postdoctoral projects
We welcome all research topics that leverage or extend the group's strengths in simulations, theory, or data science. Topics might range from fundamental questions about e.g. dark matter and structure/galaxy formation to methodological advances in numerical techniques or AI applications. We especially encourage innovative projects that create new connections between observations, simulations, and theory.

MICHAEL KUNZINGER
Research Focus
I am a mathematician working at the interface of non-smooth differential geometry, metric geometry, and mathematical general relativity. I develop rigorous frameworks for Lorentzian spacetimes of low regularity – including synthetic Lorentzian geometry and Lorentzian length spaces – in order to understand curvature, causality, and singularities beyond the classical smooth setting, in line with Einstein’s theory of gravity. My work also has close ties to the theory of Optimal Transport.. As a principal investigator of the FWF “Emerging Fields” project A new Geometry for Einstein’s Theory of Relativity & Beyond, I contribute to developing metric and synthetic notions of curvature that extend smooth methods to highly irregular spacetimes, as well as to synthetic Lorentzian spaces. Applications include non-smooth General Relativity and in Quantum Gravity.
Research environment
I am one of five Principal Investigators of the Emerging Fields project “A new Geometry for Einstein’s Theory of Relativity & Beyond” at the University of Vienna, which offers a large, very active research environment centered on non-smooth geometry, metric geometry, Lorentzian geometry and mathematical general relativity. The group currently consists of 9 postdocs and 9 PhD students, embedded in the Faculty of Mathematics, see https://ef-geometry.univie.ac.at/. For incoming postdocs, this means daily interaction with experts across optimal transport, metric measure spaces, Lorentzian length spaces, general relativity, and quantum gravity; opportunities to co-organise and speak at workshops and conferences; and intensive networking with visiting researchers from Europe and overseas. The size and diversity of the group also create natural chances for collaborative projects, informal reading seminars, and mentoring of PhD students, providing an excellent platform to build an independent research profile within a very focused but interdisciplinary team. Office space, IT-infrastructure and travel budget (3000 Euro per year) will be provided from our grant money.
Expectations towards postdoctoral fellows in this programme
As a PostDoc joining our research group you should contribute actively to (at least one of) the core themes of our research—non-smooth differential and metric geometry, Optimal Transport, Lorentzian geometry, and mathematical general relativity—by developing an independent but well-aligned research programme and by collaborating with the wider EF-Geometry team (PIs, postdocs, and PhD students), participate regularly in seminars, reading groups, and workshops, and help shape the scientific life of the group (e.g. by co-organizing events or short courses). A solid background in at least one of differential/metric geometry, analysis on metric measure spaces, Optimal Transport or mathematical General Relativity is expected, together with the ability to interact across these areas and to mentor junior researchers where appropriate.
Possible research themes or topics for postdoctoral projects

ARISTOTELIS PANAGIOTOPOULOS
Research Focus
My research centers on descriptive set theory and the dynamics of Polish groups, with a focus on understanding the complexity of classification problems via the Borel reduction hierarchy. I develop new dynamical obstructions to classification, extending and generalizing Hjorth’s turbulence theory, and study homological and cohomological invariants through the emerging framework of Definable Algebraic Topology. Much of my work builds on structural and game-theoretic methods, Fraïssé theory, and interactions with topology, ergodic theory, and operator algebras. Recent projects explore how these techniques illuminate questions in mathematical physics—such as the Problem of Observables in general relativity—opening new but complementary directions grounded in my core DST expertise.
Research environment
The postdoc will join the Kurt Gödel Research Center, a world-leading hub in mathematical logic with active groups in descriptive set theory, set theory, topology, model theory, and dynamics. They will receive office space and computing facilities provided by the Faculty, and full access to all KGRC infrastructure, including seminar rooms, the logic library, and weekly research seminars (Logic Colloquium, Set Theory Seminar, Model Theory Seminar, and various working groups). The environment is highly international, collaborative, and research-intensive, with frequent visitors and workshops. The postdoc will be fully integrated into my research group and its ongoing projects, with opportunities for collaboration across Vienna’s broader mathematical ecosystem, including the IQOQI, VCQ, and the geometry and GR groups at UniVie and TU Wien. The Faculty provides €1000/year in travel support; additional travel funds may be available through my ongoing or upcoming research grants.
Expectations towards postdoctoral fellows in this programme
We welcome postdoctoral researchers with motivation, independence, and a collaborative spirit. Members of the group are expected to take an active role in shaping their own research direction while also engaging with ongoing projects pursued by other group members. Active participation in seminars, working groups, and informal research meetings is highly encouraged, as is sharing expertise with students and colleagues. We value researchers who are open to interdisciplinary ideas and who contribute to the supportive and inclusive atmosphere of the KGRC. A willingness to explore connections across logic, topology, and mathematical physics is welcomed but not required; intellectual curiosity, professionalism, and a commitment to constructive interaction are essential.
Possible research themes or topics for postdoctoral projects
- Developing new dynamical obstructions to classification, in the spirit of Hjorth's theory of turbulence;
- Studying the dynamical properties of large topological groups (unitary groups, diffeomorphism groups, etc);
- Using the Borel reduction hierarchy to identify the intrinsic complexity of classification problems in mathematics: unitary representations, ergodic systems, topological spaces, etc.;
- Definable Algebraic Topology: developing Borel definable refinements of classical (co)homology theories;
- Fraïssé theory and homogeneous structures: classical, metric, and projective Fraïssé limits; applications to topological dynamics and continua.
- Descriptive set-theoretic methods in spacetime geometry: complexity of classes of asymptotically flat or Λ-vacuum spacetimes; descriptive gauge theory;
- Quantum symmetries and quantum Fraïssé theory: quantum automorphism groups of infinite structures; links to quantum reference frames.

MICHAEL SCHLOSSER
Research Focus
Michael Schlosser's research focuses on q-series, enumerative and algebraic combinatorics, number theory and special functions, in particular, multiple basic hypergeometric series associated to root systems, and Macdonald polynomials. A more specialized topic concerns the study of elliptic hypergeometric series, and in particular its connections to combinatorics.
Research environment
The research will be carried out within the combinatorics group of the University of Vienna. This is rather large research group (with many doctoral students and postdocs), whose members meet regularly in weekly seminars. The members who are active in algebraic combinatorics frequently present their research results in specialized international conferences such as FPSAC and SLC. The department itself is very broad and has a high reputation. Among the many activities that are offered in research and teaching, the department's colloquium, attracting various internationally renowned speakers, is a highlight. The University of Vienna has a very good library. Regarding computing facilities, remote access can be given to a supercomputing resources and data storage.
The Faculty of Mathematics will provide infrastructure, travel and computer resources.
Expectations towards postdoctoral fellows in this programme
The postdoctoral researcher should be interested to work on topics related to combinatorics and/or special functions. Ideally, the researcher should be independent or nearly independent, and have a positive working attitude. As the length of the fellowship is four years, it makes sense for the postdoctoral fellow to work on several problems at the same time. Besides working on ambitious problems which are likely to take more than a year to settle, it makes sense to work on smaller problems in parallel that allow the fellow to have a number of showable results as time progresses. It is further desired that the postdoctoral be communicative and willing to present her results in discussions, seminars and at conferences. On the technical side, it would be desired that the postdoctoral fellow has excellent programming skills.
Possible research themes or topics for postdoctoral projects
Possible themes would be elliptic hypergeometric combinatorics, or basic and elliptic extensions of special functions (such as Appell series).

Algebraic geometry: higher-dimensional geometry, commutative algebra, enumerative geometry, algebraic combinatorics.
Research environment
I lead a research group in pure mathematics, currently consisting of 2 postdoctoral researchers (one female) and 3 PhD students. There is close collaboration with the research group of Anton Mellit (Uni Wien) and Tamas Hausel (ISTA) in Algebraic Geometry and Representation Theory, as well as the research group of Ilse Fischer (Uni Wien) in Algebraic Combinatorics. We run one or two weekly seminars.
The faculty offers an office space and computer, and will contribute travel money of 1.000 euros per year. The research group will aim to contribute further travel money of up to 1.000 euros per year.
Expectations towards postdoctoral fellows in this programme
The postdoctoral researchers in my group usually pursue their own research projects in higher-dimensional Algebraic Geometry and Enumerative Geometry.

Research Focus
My work focuses on classification and structural questions in contact topology, particularly for contact 3-manifolds and the Legendrian and transverse knots they contain. I have established the equivalence of the Legendrian invariants in Heegaard Floer homology, contributed to the classification of Legendrian and transverse knots using Heegaard Floer theory and contact homology, and developed a Topological Quantum Field Theory that categorifies the Reshetikhin–Turaev invariant for the Alexander polynomial. More recently, together with Licata, I provided a new proof of the Giroux correspondence. Alongside classical tools such as convex surfaces, open books, and Heegaard Floer homology, I am interested in extending ideas from three-dimensional contact topology to higher dimensions.
Research environment
I lead a small research group in contact and low-dimensional topology at the University of Vienna. When the applicant arrives, the group will include two PhD students and one to two postdocs, allowing for close collaboration and regular discussion of ideas and ongoing work. The University of Vienna, Austria’s largest research institution, provides excellent infrastructure, extensive libraries, and access to a wide network of institutes. Nearby faculty groups in Algebraic Geometry, Combinatorics, and Complex Analysis offer complementary expertise, while ISTA, TU Wien, and ESI provide further opportunities for collaboration. I also hold FWF projects that supply additional support for travel, invited researchers, and a small seminar. Together, we aim to build and strengthen geometry and topology at the University of Vienna.
Expectations towards postdoctoral fellows in this programme
Postdocs in my group are expected to work independently while actively engaging with the team. They should hold a PhD and have a strong research profile in low-dimensional topology, in particular contact and symplectic topology and/or Heegaard Floer homology. Postdocs will contribute to ongoing projects, develop their own ideas, and discuss research regularly with me and other group members. They are encouraged to attend and present at seminars, workshops, and conferences, and to interact with related groups at the University of Vienna and partner institutes. Postdocs may also help run the group’s small research seminar and mentor PhD students, fostering collaboration and building a strong local community in geometry and topology.
Possible research themes or topics for postdoctoral projects
Postdocs in the group can pursue projects in low-dimensional topology, with a focus on contact and symplectic topology, Legendrian and transverse knot theory, and Heegaard Floer homology. Possible themes include understanding tightness and fillability in contact 3- and higher-dimensional manifolds, developing new invariants of contact structures, studying convex hypersurfaces and glueing constructions, and exploring interactions between Floer-theoretic invariants and topological or combinatorial structures.
