Janet Knutson Jansson is an American biological scientist who is the Chief Scientist at the Pacific Northwest National Laboratory. She investigates complex microbial communities, including those found in soil and the human gut. Jansson is part of the Phenotypic Response of the Soil Microbiome to Environmental Perturbations Science Focus Area, and is a Fellow of the American Society for Microbiology.{{Google scholar id}}{{EuropePMC}}
Early life and education
Jansson started her scientific career at New Mexico State University, where she majored in chemical engineering but selected electives in biology and soil science.{{Cite web |title=Spotlight on… Janet K. Jansson |url=https://academic.oup.com/femsle/article/363/15/fnw135/2197693 |access-date=2023-03-15 |website=academic.oup.com}} She has said that her soil microbiology professor, William Lindemann, introduced her to microbiology. She moved to Colorado State University for her master's degree, where she started working on soil microbiology.{{Cite web |title=Janet Jansson Biologist, Lab Fellow |url=https://www.pnnl.gov/people/janet-jansson}} She continued to explore oil biology in her doctoral research at Michigan State University, during which she developed gene probe methods for detecting bacteria in environmental samples.{{Cite thesis|degree=PhD |title=Development of gene probe methodology for detection of specific bacteria in environmental samples |first=Janet Knutson |last=Jansson|language=en|year=1998|oclc=1083792303|publisher=Michigan State University}} This was a new concept, because previously microorganisms could only be examined by microscopy. In 1988, she moved to Sweden.
Research and career

Jansson was on the faculty at the Swedish University of Agricultural Sciences where she worked as a researcher, lecturer, professor and Chair of Environmental Biology. She left Sweden in 2007, and moved to Lawrence Berkeley National Laboratory as a senior staff scientist.{{Cite web |date=2018-11-05 |title=Janet Jansson, PhD |url=https://microbiomeinsights.com/team/janet-jansson-phd/ |access-date=2023-03-15 |website=Microbiome Insights |language=en-US}} She held a joint position at University of California, Berkeley and the University of Copenhagen.{{Cite web |title=Janet K.

In 2014, Jansson joined the Pacific Northwest National Laboratory, where she was made Chief Scientist for Biology. Her research considers multi-omics based strategies to investigate microbial organisms.{{Cite web |title=Multi-Omics of the Microbiome presented by Janet K. Jansson, Ph.D., PNNL |url=https://events.wsu.edu/event/multi-omics-of-the-microbiome-presented-by-janet-k-jansson-ph-d-pnnl/ |access-date=2023-03-15 |website=Events |date=14 January 2019 |language=en-US}} She has studied how climate change impacts microbial communities in ecosystems: how warming impacts permafrost soil microbiomes and how drought impacts grassland soils. She is also interested in the human microbiome: how diet and disease impact the gut microbiome. She was the first to use molecular techniques such as genome sequencing to understand the human gut, gaining insight about the types of microbes that were involved in health and disease.
At the Pacific Northwest National Laboratory, Jansson leads the focus area on Phenotypic Response of the Soil Microbiome to Environmental Perturbations.{{Cite web |title=Phenotypic Response of the Soil Microbiome to Environmental Perturbations |url=https://genomicscience.energy.gov/pnnl/ |access-date=2023-03-15 |language=en-US}} The program looks to develop a comprehensive understanding of soil microbial responses to changing moisture.{{Cite web |title=PNNL Soil Microbiome SFA {{!}} Datahub |url=https://data.pnnl.gov/group/nodes/project/12620 |access-date=2023-03-15 |website=data.pnnl.gov |language=en}} She served as President of the International Society for Microbiology.{{when|date=March 2023}}{{citation needed|date=March 2023}} She was appointed to the National Academy of Sciences committee on Soil Sciences in 2020.{{Cite web |title=Janet Jansson Appointed to the U.S. National Committee for Soil Science {{!}} PNNL |url=https://www.pnnl.gov/news-media/janet-jansson-appointed-us-national-committee-soil-science |access-date=2023-03-15 |website=www.pnnl.gov}}
She is currently on the Scientific Advisory Board of Seed.
