Leo Lahti is Docent in applied mathematics and Academy Research Fellow at the Department of Mathematics and Statistics where he leads the Computational biosciences group. He obtained PhD in statistical machine learning and bioinformatics in 2010 in Aalto University, followed by a six year postdoctoral period in The Netherlands and Belgium. Lahti is also a founding member of Helsinki Computational History group and Open Knowledge Finland working groups which received Ministry of Education awards on Open Science in 2016 and 2017, respectively. His current research focuses on modern data science methods and applications in human microbiome research. More info:

Manu Tamminen is developing and applying single cell genome sequencing techniques to gain improved insights into complex bacterial communities and their role at the emergence of antibiotic resistant bacterial strains. He defended his doctoral thesis at the University of Helsinki and has since carried out his research at MIT and ETH Zürich. He is currently employed as a senior lecturer of genetics at the University of Turku.
