Reetta studied biology, microbiology, and biochemistry in the Moscow State University, Russia and in the University of Helsinki (UH), Finland and received her MSc. and Ph.Lic. (Licentiate) in microbiology in 1996 and 1999, respectively from the UH.  She then worked as a researcher in VTT Technical Research Centre, Espoo, Finland and did her PhD thesis research on human intestinal lactobacilli and bifidobacteria as a joint-project between VTT and the Wageningen University (WU), The Netherlands, where she worked in 1999-2001. She obtained her Ph.D. in 2002 from WU, NL. As a post-doc she worked in VTT and in the University of Turku, Finland and was involved in several projects on the development of a novel DNA/RNA detection technique as well as in research on intestinal microbiota and probiotics.

In 2008, Reetta was nominated as a docent (adjunct professor) in microbiology. Since 2011, she has been leading her own research group on human intestinal microbiota and host-microbe interactions in UH.

When Reetta is not occupied with science, she likes to make handicrafts with her daughter, enjoy nature in the Turku archipelago and to exercise belly movements in oriental dancing classes.

Veera obtained MSc (2004) and PhD (2012) in general microbiology from the Department of Biosciences, University of Helsinki. She has worked as a postdoc in the research group of Docent Reetta Satokari (Faculty of Veterinary Medicine and Faculty of Medicine, University of Helsinki) and in the research group of Professor Riitta Korpela (Faculty of Medicine, University of Helsinki)

The focus of Veera's research is in studying microbe-host interactions i.e. adhesion of bacteria and binding of the bacterial proteins to components of the human and animal host tissues and bacterial interaction with the host epithelium as well as the effects of bacteria to epithelial barrier function and their anti-inflammatory potential.

Veera's main interests outside of science are sport and gymnastics.

Jonna defended her PhD thesis in 2014 from the group of Willem de Vos (Faculty of Veterinary Medicine). Her main research area was intestinal microbiota in healthy subjects and how it is effected by disease. She continued as a post-doc researcher with Reetta Satokari concentrating the effect of FMT in recurrent Clostridium difficile infection. Jonna later also joined the group of Prof Robin Spiller in Nottingham University for second post-doc period and was awarded an honorary assistant professorship in University of Nottingham.

Currently Jonnas research concentrates on the microbiota changes in different diseases states including irritable bowel syndrome (IBS) and inflammatory bowel diseases (IBD).

When not analysing data, Jonna spends her time with her two children and enjoys live music and culture.

In 2015 Kaisa gained her M.Sc. degree in Food Chemistry at the Faculty of Agriculture and Forestry at the University of Helsinki. In her M.Sc. thesis Kaisa studied the effect of different carbon sources on the vitamin B12 production in Propionibacterium strains, which was part of a four-year Academy-project called "Natural fortification of foods: microbial in situ synthesis of vitamin B12 and folate in cereal matrix". Kaisa also carried out a six-month traineeship in 2014 in the UK at the University of Manchester at Institute of Inflammation and Repair studying the effect of probiotic lysates on the expression of ABC transporters in epidermal keratinocytes and intestinal epithelial cells.

Kaisa has worked in Reetta Satokari’s group since 2011, first as a research assistant and now as a doctoral student of microbiology. She belongs to the Microbiology and Biotechnology Doctoral Programme (MBDP). The focus of her PhD project is on isolating and identifying anti-inflammatory commensals from healthy human gut and characterizing the most interesting, anti-inflammatory action exerting isolates in more detail e.g. their adhesion and epithelial cell strengthening capacity.

Besides work, Kaisa is passionate about latin dances, such as salsa, sensual bachata and reggaeton, as well as traveling.

Hanne is a PhD Student in the Doctoral Program in Biomedicine at the Faculty of Medicine. In her PhD project, she studies long term changes that treatment with a fecal microbiota transplantation has on the gut microbiota and resistome of recurrent Clostridium difficile infection-patients.

Hanne holds degrees of Master of Science in Microbiology and Bachelor of Science in Food Microbiology from the Faculty of Agriculture and Forestry, University of Helsinki. She has been working in the Satokari group since the beginning of year 2015, when she started her Master’s thesis work, titled “Binding of fecal bacteria to Caco-2 cell line as a pre-selection step in isolating commensals with potential to inhibit Clostridium difficile adhesion”.

Before going in for an academic career, Hanne was working first as a Laboratory Assistant and later as a Senior Laboratory Technician in Laboratory of Microbiology and Hygiene at the Faculty of Medicine, University of Helsinki.

In addition to bacteria, Hanne loves dogs, trees and fungi and she relaxes by walking in the forests and seasides surrounding her home.

Aki is a microbiology major in the Department of Food and Environmental Sciences, University of Helsinki. Currently, Aki is working with his Master´s thesis in which his aim is to isolate donor-derived bifidobacteria from fecal samples of recurrent Clostridium difficile patients.

For the better part of the last decade, Aki has been doing routine analytics in the fields of clinical and environmental microbiology. Aki´s main interests in microbiology are host-bacteria relationship, quorum sensing, and biofilm formation. He has also a special interest in laboratory quality management systems.

When not working in the lab, Aki devours popular culture in all of its aspects.

Anna is working as a research assistant and participating in group’s several projects. She is Bachelor of Science in Microbiology and a Master’s student in Department of Food and Environmental Sciences, University of Helsinki. Anna has been working with DNA-based methods (PCR, qPCR and extraction of DNA by using a large-scale method), isolating bifidobacteria and helping with daily tasks in the lab.

Earlier, Anna has been working as a research assistant in a couple of other laboratories and she has also been a trainee in Evira (Finnish Food Safety Authority). 

In addition to these topics, Anna is interested in fungi and their use in biotechnology. Currently, she is also writing her Master’s thesis on that topic. In her free time Anna likes to enjoy good live music and spend time in the nature.

Maiju is a master’s student in microbiology at Department of Food and Environmental Sciences, University of Helsinki. Her master’s thesis focuses on isolation and characterization of sporulating Clostridia-type commensals from human feces.

Before her academic studies, Maiju has worked as a biomedical laboratory scientist in clinical laboratories serving hospitals and health care centers. At her free time, Maiju likes to play badminton, enjoys good food, and goes out to the nature.
