The Museomics Research Group located in the Kaisaniemi Botanical Garden of the Finnish Museum of Natural History (LUOMUS) also part of the Organismal and Evolutionary Biology (OEB) Research Programme, Faculty of Biological and Environmental Sciences. We employ cutting-edge genomic techniques on historical DNA (hDNA) from non-model plant species as well as their microbial communities to investigate complex evolutionary processes underpinning plant biodiversity. We also investigate our research results from an interdisciplinary perspective focusing on unique links from the past based on handwritten and printed archival records using deep learning algorithms that are particularly relevant for scientific outreach and higher education.
