Education

MSc Informatics, The University of Edinburgh (2014⁠–⁠2015)

Specialism: Learning from Data

C++, Python, nltk, matplotlib, LaTeX

Master thesis: "Handling out-of-vocabulary words in a domain adaptation setting in statistical machine translation"

Out-of-domain MT is sensitive to the alignment of rare words. 27 % of untranslated words in the output could be found in training data, but were too rare for the word alignment algorithm to extract.

BSc Electrical Engineering, TU Wien (2010⁠–⁠2014)

C++, LaTeX

Matlab

Bachelor thesis: "Interfacing of the PARDISO Sparse Linear Solver for Schrödinger-Poisson simulation"

10-25 % overall speedup of simulations through refactoring the C++ codebase to introduce a representation of sparse matrices and interfacing a sparse solver package.

IT and Organisation, HTBLVA Spengerg. 20, Wien (2005⁠–⁠2010)

C++, Java

Specialism: Commercial IT
Diploma project: "Distributed server monitoring"
Higher Institute of Technology (HTBLVA für EDV)
1st, 2nd places at Austrian Olympiad in Informatics 2009 and 2010.
