Rate My Professor Nils Birkholz

Dr Nils Birkholz is a Research Fellow in the Department of Microbiology and Immunology, Faculty of Biomedical Sciences, at the University of Otago. His research centers on bacterial defence systems and their interactions with mobile genetic elements, with a particular emphasis on bacteriophages, CRISPR-Cas systems, anti-CRISPR proteins, and restriction-modification mechanisms. Working in the Fineran Lab, Birkholz explores how bacteria deploy immune strategies against viral invaders and how phages develop counter-defences to overcome these protections. This includes investigations into the regulation of anti-CRISPR operons, phage-encoded inhibitors of bacterial immune signaling, and the structural basis of anti-CRISPR control mechanisms. His contributions advance the understanding of prokaryotic immunity and have implications for combating antibiotic-resistant pathogens through phage-based therapies.

Birkholz has published extensively in leading journals, with key works including 'A host of armor: Prokaryotic immune strategies against mobile genetic elements' (2023), 'Inhibitors of bacterial immune systems: discovery, mechanisms and applications' (2024), 'Conquering CRISPR: how phages overcome bacterial adaptive immunity' (2021), 'Phage anti-CRISPR control by an RNA- and DNA-binding helix-turn-helix protein' (2024), and 'Anti-CRISPRs deconstruct bacterial defense' (2024). In 2024, he received the Asia-Pacific Protein Association Young Scientist Award for his research on the interplay between bacterial defences and phages, particularly how phages control anti-CRISPR production. Birkholz has presented his findings internationally, such as at the Biomolecular Horizons Congress in Melbourne (2024) and the Maurice Wilkins Centre Research Symposium in Auckland (2025). His publications have accumulated over 500 citations, reflecting his impact in the field of molecular microbiology.
