Shuqing Xu obtained his PhD from ETH Zürich under the supervision of Prof. Florian Schiestl and Prof. Alex Widmer in 2011. His PhD thesis focused on the evolution of floral signals in a specialized pollination system. Between 2012 and 2017, he moved to Max Planck Institute for Chemical Ecology in Jena as a project group leader in the Department of Molecular Ecology (led by Prof. Ian Baldwin), where he worked on the evolutionary genetics of plant defences. In 2018, he was appointed as an associate professor (W2) at the University of Münster. Since April 2022 he is the department chair of evolutionary plant sciences at the University of Mainz. He is a father of three children.

Nijat joined the group in June 2022. He received his PhD in community and behavioural ecology at the University of Koblenz-Landau, Germany in 2022. He is interested in understanding the mechanisms and consequences of animal behaviour. He is currently working on the role of niche choice on host plant adaptation in Colorado potato beetles. His project is part of the NC3 initiative.
Dr. Pablo Duchen
E-mail: pduchnbo@uni-mainz.de
Pablo joined the group in July 2021 as a junior group leader. He received his PhD in theoretical population genetics at the University of Munich (Prof. Wolfgang Stephan), Germany in 2014. His research concerns the evolution of adaptation at both the population genomic and phenotypic levels, as well as the link between these levels. His approach is computational and theoretical, with direct applications to real biological datasets. He is currently leading a sub research group in the department.
Patrycja joined the group in June 202
4. She obtained her PhD at the John Innes Centre in Norwich, UK, focusing on plant metabolism and mineral nutrition. In 2019 she moved to the Max Planck Institute for Chemical Ecology in Jena to research mate selection and reproduction mechanisms of wild tobacco. At JGU, she is developing a synthetic biology toolbox to study the evolution of specialized secondary metabolites.
