Dr Eissmann received his PhD in cancer biology from the Goethe University (Frankfurt) in 2012. He came to Australia for Postdoctoral research at the Walter & Eliza Hall institute then joined the Olivia Newton-John Cancer Research Institute in 2015. He is interested in cytokine signalling networks in the tumor microenvironment of gastro-intestinal cancers and has established novel GI cancer mouse models presenting all disease stages, enabling research on the role of cytokine signalling in immune cell infiltrates on disease progression and therapy responses. Now, his work focuses now on understanding the cytokine-driven immunosuppressive immune environment’s role in immune checkpoint blockade efficacies in gastric and colorectal cancers.
