Plant pathology

Monika Maurhofer is the leader of a research group with interest in elucidating the multitrophic interactions going on in the hotspot rhizosphere with a focus on physical and molecular interactions between plants, plant pathogenic fungi, plant beneficial pseudomonads and insect pests. Her research is aims at improving the use of microorganisms for the control of plant diseases and insect pests.

Her group is part of the plant pathology group which is headed by Prof. Bruce McDonald and located in the Institute of Integrative Biology. Monika Maurhofer is also involved in teaching and gives lectures in systematics and ecology of fungi and algae for first year ETHZ biology and pharmacy students and offers a block course in plant pathology for third year ETHZ and UniZH biology students.
