In her PhD research, Lieselotte investigated the spreading potential of resistant parasites, because resistance is a major problem for current therapy and disease control. This way, Lieselotte contributed to the &#8220;One Health&#8221; approach in which multiple disciplines seek integration to achieve optimal health for humans, animals and the environment.
