Prof. Dr. Angelika Wiegele
Department of Mathematics, Alpen-Adria-Universität Klagenfurt

Angelika Wiegele is a mathematician working on semidefinite optimization 
and combinatorial optimization. She is Professor at the 
Mathematics Department at the Alpen-Adria-Universität Klagenfurt.
She received her Ph.D. in Mathematics at the Alpen-Adria-Universität 
Klagenfurt (Austria) in 2006. She was a researcher and lecturer at TU 
Graz, Department of Mathematics and at Alpen-Adria-Universität Klagenfurt. 
She was employed within a Marie Skłodowska-Curie funded project at 
IASI-CNR in Rome and at the University of Cologne, Department of Computer 
Science. Recently, she was visiting professor at the Università degli 
Studi di Roma "Tor Vergata", Department of Civil Engineering and Computer 
Science Engineering.

Her research interests lie in the field of semidefinite optimization, in 
particular, in the application of semidefinite methods for solving 
mixed-integer nonlinear optimization problems. Her research projects have 
been funded by the Austrian Science Fund FWF and by the European Union's 
Horizon 2020 program.
