Randall J. Olsen

Randall J. Olsen studies infectious disease-causing bacteria and viruses, with a focus on group A and group C/G streptococcal infections (including Streptococcus dysgalactiae and Streptococcus pyogenes), Haemophilus influenzae, and SARS-CoV-2. His work combines bacterial and viral genome sequencing with clinical patient data to track how pathogens evolve, spread, and cause disease outbreaks, often in collaboration with public health surveillance efforts in locations such as Houston, Iceland, and Spain. Some recent work also touches on genomic biomarkers in lung cancer.

Publication output has fluctuated over the last decade, with a dip around 2023 followed by a rebound to higher output in 2024-2025, though the 5-year average (about 4 papers/year) is lower than levels seen earlier in the decade.
