Lars Engstrand

Lars Engstrand is a Professor in infection control at Karolinska Institutet, heading the Translational Microbiome Research and Pandemic Preparedness group within the Department of Microbiology, Tumor and Cell Biology. His research spans multiple disciplines with a focus on translational microbiome research and pandemic preparedness.

Engstrand's research interests center on understanding the human microbiome's role in health and disease, particularly in women's reproductive health and gastroenterology. His group has established multiple large-scale clinical studies including SweMaMi (Swedish Maternal Microbiome project), BASIC (associations between microbiota and preterm birth), VaMiGyn (Vaginal Microbiota in Gynaecological health), and several others investigating the vaginal microbiome's relationship to pregnancy outcomes, HPV infection, and cervical cancer. His team also conducts significant research on gut microbiome in inflammatory bowel disease and colorectal conditions through projects like PopCol and KOLBIBAKT.

Analysis of Engstrand's most recent publications reveals a strong focus on the relationship between microbiome composition and women's health outcomes. His research consistently examines how vaginal, gut, and oral microbiomes influence pregnancy complications, preterm birth, HPV infection, and mental health during pregnancy. The work often employs large cohort studies with comprehensive sampling strategies across multiple body sites and time points, providing robust data for understanding microbiome dynamics in health and disease.

Engstrand leads the Microbiome Exploration and Development for Intervention (MEDI) initiative and the National Pandemic Center (NPC) at Karolinska Institutet. The NPC conducted large-scale sequencing during the COVID-19 pandemic and has amassed over 1.5 million samples. His research group includes multiple specialized teams focusing on culturomics, bioinformatics, labcore operations, women's health research, and pandemic preparedness.
