PhD Student

Tobias did his bachelor of biology and master of environmental sciences both at the Albert-Ludwigs Universität Freiburg. The study of the interaction of tree species diversity on light use in mixed forest stands for his bachelor thesis brought him to investigate the effect of tree species diversity on the infestation behaviour of the sixtoothed spruce bark beetle for his master thesis.
He is now working on semiochemical ecology of the European spruce bark beetle. Focus of the VerbIps project lies on verbenone, often referred to as a “universal bark beetle repellent”. He is interested in the small scale mechanisms that can lead to outbreaks that are visible on a landscape scale, mediated by both, beetle pheromones, but also host and non-host plant interactions. He is currently working for the Forest Research Institute Baden-Württemberg in the department of forest health.
