Joel completed his Bachelor of Science degree (majoring in Medical and Molecular Microbiology) with honors in the lab of Cynthia Whitchurch, where he studied the role of extracellular DNases of Pseudomonas aeruginosa. He then undertook his PhD in the lab or Trevor Lithgow, where he co-discovered a novel secretion machine (the Translocation and Assembly Module – TAM) that diverse Gram-negative bacteria use to transport adhesive proteins to the bacterial cell surface. For his first postdoctoral appointment, he then moved to Singapore in the lab of Sven Pettersson (NTU) to study how commensal gut microbiota modulate animal behavior and brain function. He then moved to the EMBL in Heidelberg (Germany) as an EMBO Long Term and EIPOD fellow where he adapted and established several proteome-wide approaches to enable the discovery of novel mechanisms underlying host-microbe interactions.

Since February 2022, he joined the Medical Microbiology Department at the RWTH University Hospital in Aachen as a W1 Junior Professor in Mucosal Infection Biology. His research focusses on using proteomics as a tool to drive the discovery of effector proteins secreted by human gut microbiota, with the aim of elucidating their role in human health and disease.

Postdoctoral Fellow

Marléne Birk, PhD
Postdoc
mbirkukaachende

Marlène completed her Bachelor of Science degree in agricultural sciences at Giessen University and then moved to Wageningen to pursue a master’s degree in plant biotechnology, with a specialized focus on plant‐microbe interactions. For her PhD Marlène joined the laboratory of Emmanuelle Charpentier at the Max‐Planck‐Unit for the Science of Pathogens where she developed a new LC‐MS‐based multiplexed protein quantification method to simultaneously determine time‐resolved protein degradation and synthesis in Listeria monocytogenes during infection. In May 2022 she joined the Selkrig Lab at the University Hospital Aachen.
