M. Timothy Rabanus-Wallace’s primary research interests are in evolutionary processes, genomics, and bioinformatics. He completed his PhD at the University of Adelaide in 2017, during which he analysed ancient plant DNA and stable isotope data to reconstruct ecological shifts at the end of the last glacial period. He subsequent joined the Genomics of Genetic Resources research group led by Nils Stein at IPK Gatersleben, as a postdoctoral researcher and staff scientist. In this capacity he works on the exploitation of genetic material from genebanks, and develops assembly and analysis approaches for crop genomes, most prominently rye.The research focus of Nils Stein is on genome dynamics and evolution, structural and comparative genome analysis of the small grain cereals barley, wheat and rye—with a leading role in the sequencing of all three crop genomes. Recent activities emphasize on the analysis of the pan-genome of barley and wheat and on the systematic catalogingof global barley diversity in ex situ diversity collections as a proxy for barley systems genomics and genomics based plant breeding. After graduating in Biology (1993, Kaiserslautern University, Germany), PhD in Genetics (1997, Hohenheim University, Germany) and postdoc research (Zurich University, Switzerland), Nils Stein joined IPK Gatersleben in 2001 to become a group leader in 2007. Since 2018, after declining other offers, he is a joint professor (W3) of Plant Genetic Resources between Georg-August-University Göttingen and IPK Gatersleben.
