معرفی
Christian Freund is Professor of Protein Biochemistry at the Institute for Chemistry & Biochemistry, Freie Universität Berlin, holding this W2 professorship since 2011. He serves as Coordinator of the FU Berlin-UCSF Collaborative Initiative and Founding Member/Vice-chair of the DFG Collaborative Research Centre SFB/TRR 186 on Molecular Switches in Cellular Signal Transmission, leading interdisciplinary research across Berlin and Heidelberg institutions.
His academic foundation includes Chemistry studies at Heinrich-Heine-Universität Düsseldorf (1983-1986) and Ludwig-Maximilians-Universität München (1986-1989), followed by a PhD in Structural Biology at the Max-Planck-Institute of Biochemistry (1994) and Habilitation in Biochemistry at Freie Universität Berlin (2005).
Freund's research integrates structural biology, biophysics, and immunology to investigate molecular mechanisms of antigen presentation and cellular signaling. His work centers on MHC class II dynamics, protein conformational switches, and nanoscale organization of signaling complexes, employing NMR spectroscopy, quantitative proteomics, and molecular engineering to dissect immune recognition pathways and neuronal signaling mechanisms.
Analysis of his 2010-2019 publications reveals consistent focus on MHC-mediated antigen presentation (60% of works), with significant contributions to understanding peptide exchange dynamics and HLA-DM editing functions. Secondary research streams explore synaptic protein networks (25%) and T cell signaling machinery (15%), demonstrating methodological breadth across structural biology, proteomics, and cell biological approaches.
His scientific recognition includes:
- Biofuture award from the German Ministry of Education and Research (1999)
- Swiss National Funds Post-doctoral Scholarship (1997)
- Innovationswettbewerb Medizintechnik grant (2009)
As research group leader at Leibniz-Institute of Molecular Pharmacology (2000-2011) and current FU Berlin professor, Freund has secured major collaborative funding through DFG SFB/TRR 186 and the UCSF partnership. His mentorship spans postdoctoral fellows at Harvard/Dana-Farber and Leibniz-Institute, with current supervision of graduate students in the Berlin biochemistry program.
Freund directs a research group within FU Berlin's Institute for Chemistry & Biochemistry, operating as core component of SFB/TRR 186. His laboratory maintains active collaborations with UCSF's QBI (Nevan Krogan) and Heidelberg-based structural biology teams, utilizing advanced NMR, cryo-EM, and single-molecule imaging facilities across the Berlin-Heidelberg research alliance.
