Irene Tubikanec

I am currently holding a postdoctoral position at the Department of Statistics
of the University of Klagenfurt in Austria. Before I was a postdoc at the 
Johannes Kepler University Linz, where I defended my PhD thesis,
written under the supervision of Professor Evelyn Buckwar and co-supervision
of Dr. Massimiliano Tamborrino, in February 2021.

Research interests

Research interests

My interests lie at the interface of (multi-dimensional and non-linear) stochastic differential equations, efficient and structure-preserving numerical simulation methods and statistical inference procedures.

I like to connect different ideas and disciplines, and to deal with real-life applications.

​

Keywords:

  • Stochastic models (mainly SDEs/diffusion processes and Hawkes processes)

  • Mathematical neuroscience

  • Numerical methods for SDEs (Splitting methods, Structure-preservation)

  • Approximate Bayesian computation

  • Network inference

  • EEG data
