I am a postdoctoral researcher at the Department of Linguistics at the University of Tuebingen. My reseach focuses on Markov Chain Monte Carlo methods for phylogenetic applications.

Research

My research focuses on Markov Models and their application to computational historical linguistics. The increasing availability of data facilitated the use of algorithmic methods to answer questions in historical linguistics. Markov Models are of great use in this research area from modelling alignments to the framework of Markov Chain Monte Carlo for the inference of phylogenetic models. I am focussed on using Markov Chain Monte Carlo and Hamiltonian Monte Carlo methods for the purpose of inferring phylogenies and typological inferences.

Software

MCPhylo

(Hierarchical) Phylogenetic Models in Julia

This package does phylogenetic computations in Julia. The goal is to facilitate phylogenetic computations in computational historical linguistics. To facilitate the inference of phylogenetic trees, Probabilistic Path Hamiltonian Dynamics.

MCPhyloTree

The tree Module for the MCPhylo package.

This package provides the tree module for the MCPhylo package. It provides basic functionalities for (phylogenetic) tree manipulation.
