Eliisa graduated as medical doctor from University of Helsinki in 2006. In 2011 she defended her PhD on Autoimmune regulator in the maintenance of immunological tolerance. She continued her research as a post-doc at Center for Infectious Medicine, Karolinska Institutet, Stockholm Sweden. There she worked in prof. Hans-Gustaf Ljunggren’s group on tissue-resident natural killer cells. After returning to Finland in 2014, she started her specialization into clinical microbiology at HUSLAB, University Hospital Helsinki. Currently she shares her working hours between managing the research group and as a clinical specialist at HUS Diagnostic Center HUSLAB, division of immunology. In her clinical work, she focuses on the laboratory diagnostics of inborn errors of immunity.
Eliisa’s ideology to research is that it should be fun. Fun means bold experiments in a relaxed working environment. We do hard work when needed, but also maintain a reasonable work-life balance. We work as a team, and every team member is important. Every day we learn something new!

Dawit holds MSc. in Bioinformatics from Aalto University and PhD from University of Helsinki during which he worked extensively on the application and development of Bioinformatic methods for the analysis of high-throughput genomic datasets. He has extensive experience from basic analysis of genomic data to higher level analyses in areas such as variant analysis, gene expression analysis from microarrays to RNAseq (both bulk and single cell data), and immune TCR repertoire analysis.
In his current post-doctoral research, Dawit is involved in the analysis of scRNAseq datasets in projects that study immunological disorders & immunodeficiencies. He utilizes bioinformatics, develops in-house pipelines/methods, and harnesses statistical and machine learning algorithms to help answer critical research questions.
Vasco joined the Kekäläinen Lab in 2024, coming directly from Jyväskylä, where he conducted research on skeletal muscle lipid droplets in the context of insulin resistance and exercise. His current focus is exploring the impact of immune cells' lipid metabolism on thymus health, primarily through a spatial biology and bioimage analysis approach. In his leisure time, Vasco publishes mushroom science and indulges in the grappling arts of Judo and BJJ.

With the purpose of better being able to predict viral reactivations and infections, he is looking for answers to why and how immune suppression causes viral infections in the post-transplant setting.
As a pediatrician specializing in hematology, his special interests are acute leukemia, virology and immunology. In his spare time, he spends with my family, and every once in a while, on the golf course.
Pauliina is a PhD Student in the Pediatric Research Center and Translational Immunology Research Program and specializing in pediatrics in the New Children’s hospital. Her research focuses on the diagnostics of primary immunodeficiencies and immune reconstitution after allogenic stem cell transplantation in pediatric patients.
Joona started in the Kekäläinen Lab in 2017 doing "bachelor´s thesis" on anti-cytokine antibodies. Fascinating world of immunology got a grip of him and alongside with medical studies, he started his PhD project in 2019 supervised by PI Kekäläinen and Dr Laakso. In 2021 he graduated as MD from University of Helsinki and currently he is continuing his PhD project.
His main focus is in Germinal Center reaction where he wants to understand how follicular T helper and regulator cells fine tune development of memory B cells and antibodies producing plasma cells. He studies different forms of Germinal Center reaction in autoimmunity (especially neurological diseases multiple sclerosis and myasthenia gravis), immunodeficiency and ovarian cancer with means of flow cytometry, (sc)RNAseq and especially image analysis based on multiplex immunofluorescence stainings.
Suvi is a medical student/PhD student with a research focus on the immunological effects of COVID-19. She started at the lab in 2018 through the MD PhD program researching MAIT cells, but once the COVID pandemic hit, she changed projects.
Kirsten was a student in the translational medicine master's program. She completed her BSc in reproductive biology at the University of Edinburgh and her Msc project studying scRNAseq compatible cell preservation and fixation methods. She is now a PhD student in the Kekäläinen lab.
Xiaobo started her PhD project in Kekäläinen lab from 2021 under the supervision by Eliisa Kekäläinen and Tomas Strandin.
Her main focus is T cell lymphopenia in respiratory viral infections, especially SARS-CoV-2 infection.
During Alexandra's bachelor’s program, she conducted research at the laboratory of molecular biology at IB Komi SC UB RAS (Russia), focusing on typing specific HLA genes associated with early-onset rheumatoid arthritis. The primary objective of this research was to explore potential molecular-genetic markers for preventive diagnostics. Subsequently, she pursued her MSc studies at the University of Tartu (Estonia), where she investigated the utilisation of epigenetic changes to estimate immune cell levels.
Currently, she is focusing on T-Cell Repertoire implemented as a potential source of personalised treatment options, where we explore APECED patients’ cell receptors and their potential applications in treatment options.
