Karlovsky lab closed

You find archived content here: photos of our team over 20 years; a list of lab members; our publications (some are still coming); and Petr's farewell paper with a dedication in the Acknowledgment. Our research on mycotoxins is continued by Dr. Mohammad Alhussein in the lab. of Prof. Michael Rostás. Mohammad also continues our Fungal Toxins course, to which Petr still contributes. (Note that the images below are clickable: curious?)

Gaenseliesel Karlovsky lab - from 2001 to 2021 Karlovsky lab 2020: Soil sampling for microbiome analysis Karlovsky lab: analytical chemistry News from Karlovsky lab

About our research

We studied biological functions of secondary metabolites, mycotoxins and their detoxificatiton, and selected topics related to soil microbiomes and fungal chemical ecology. Most of our work was published under open access. The laboratory closed with Petr's retirement in Oct. 2021.
