Between 2014 and 2024, Ionescu conducted his research at the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB), where his research focused on the genomics and ecology of giant bacteria, specifically the genus Achromatium. Notably, in 2017, Ionescu discovered that the multiple chromosomes harbored by these large bacteria are not identical, highlighting their adaptability to different environments.
In 2021, Ionescu has received the independent research grant from the German Research Foundation (DFG) to further explore these topics.
