Steven Thijsen

Dr. Steven Thijsen is a Full Professor at Erasmus MC, Faculty of Medicine, in the Department of Medical Microbiology & Infectious Diseases. His work bridges clinical microbiology, infectious disease research, and public health, with a strong emphasis on diagnostic methodologies and epidemiological surveillance.

His research interests span Lyme borreliosis, tick-borne infections, SARS-CoV-2 diagnostics, antibiotic resistance, and immune responses in severe infections. He has contributed extensively to understanding seroprevalence patterns and improving laboratory testing accuracy for complex infections.

The most recent publications highlight a consistent focus on diagnostic validation, serological profiling, and large-scale collaborative studies. Themes include two-tier testing for Lyme disease, benchmarking of molecular assays for SARS-CoV-2, and longitudinal analysis of pathogen exposure in at-risk populations.

While no formal awards are listed in the provided text, his leadership in national working groups—such as the SARS-CoV-2 Diagnostics Working Group in the Netherlands—and multi-institutional collaborations suggest recognition within the field. He is actively involved in research grants and quality improvement initiatives in clinical diagnostics.

His network spans public health institutions, clinical laboratories, and research centers in the Netherlands and beyond. Though no specific lab name is mentioned, his work appears to be embedded within Erasmus MC’s infectious disease research infrastructure, likely involving a team focused on clinical microbiology and translational diagnostics.
