The meeting, Tumor Immunology meets Oncology (TIMO)“ has established itself as an outstanding platform for exchange between scientists, clinicians and junior staff and as one of the leading European conferences in the field of tumor immunology. From 24-26 September 2020, it will take place for the 16th time at the Martin Luther University Halle-Wittenberg in the lecture hall of the University Hospital Kröllwitz, Halle (Saale). With an increasing number of participants and a positive echo throughout, we are able to win not only highly recognized national but also international speakers – just to name a few keynote speakers of the past years: Shuji Ogino (Dana-Farber Cancer Institute Boston, 2019), Thomas Gajewski (University of Chicago, 2018), Alberto Mantovani (Instituto Clinico Humanitas Milan, 2017), Olivera J. Finn (University of Pittsburgh, 2016), Nicholas McGranahan (The Francis Crick Institute London, 2015).
