Dr. David van Duin is the founding Director of the Immunocompromised Host ID service. His main research interests are multi-drug resistant Gram-negative bacteria, and infections in immunocompromised patients. He is the PI for the MDRO Network of the Antibacterial Resistance Leadership Group. Within the MDRO Network, the consortium on resistance against carbapenems in Klebsiella and other Enterobacterales (CRACKLE) has been completed. In addition, studies on ESBL-producing Enterobacterales, carbapenem-resistant Pseudomonas aeruginosa, and carbapenem-resistant Acinetobacter baumannii are ongoing. He is also funded to explore the community origins of highly resistant bacteria.
