Irene Tubikanec

I am currently holding a postdoctoral position as university assistant

at the Institute of Stochastics of the Johannes Kepler University Linz in Austria,

where I defended my PhD thesis, written under the supervision

of Professor Evelyn Buckwar and co-supervision of Dr. Massimiliano Tamborrino,

in February 2021.

Postdoc at the

Institute of Stochastics

Johannes Kepler University Linz (Austria)

 

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

  • Splitting methods

  • Structure-preservation

  • Approximate Bayesian computation

  • Causal inference

  • EEG data
