key words: Morphometrics, turtles, South-East Asia, shape variation and evolution, comparative phylogenetic methods, quantitative genetics.

What do I do:

I am primarly interested at understanding shape variation and evolution of animals in a natural, developmental and ecological context. Quantifying biological shapes for later analyzing them makes therefore part of the core of my researrch. I am also interested in turtle systematics and evolution, and I am working on fossil and living vertebrate communities in South-East Asia. I teach biostat, vertebrate zoology, and evolution.
