Eleftherios Kastis

Dr Eleftherios Kastis is a Lecturer in Pure Mathematics at the School Of Mathematical Sciences, Lancaster University. His research and PhD supervision focus on foundational mathematical disciplines.

Research Interests:

• Graph Rigidity: Specializing in rigidity properties of partially triangulated orientable and non-orientable surfaces, with an analytic approach to periodic and symmetric structures.
• Non-selfadjoint Operator Algebras: Investigating reflexivity and chirality in operator algebras generated by unitary semigroups.
• Matroid Theory and Combinatorial Rigidity: Active participation in collaborative research initiatives.

Publications: Dr Kastis has contributed to geometric rigidity theory, including recent work on expansive motions in singly-periodic pseudotriangulations.

PhD Supervision: Current advisee includes Jack Esson (focus areas: Analysis, Geometric Rigidity).

Academic Collaborations: Involved in the North British Functional Analysis Seminars (NBFAS) and Young Functional Analysts' Workshop (YFAW) since 2020, and contributes to research groups in Combinatorics and Geometric Rigidity.
