ABOUT TOM CHEN
As the Senior Director and Head of Drug Substance and Early Development CMC Lead at Dianthus Therapeutics, I oversee the CMC team for biologic products in pre-clinical and clinical stages. I direct and develop the clone selection, cell culture, process development, product characterization, analytical method development/validation, and regulatory document preparation. I also build and maintain strong relationships with internal and external partners to ensure successful analytical strategies for the pipeline molecules.I have over 20 years of experience in protein biochemistry research and drug development, with a PhD in Biochemistry from Max Planck Institute and LMU Munich. I have extensive expertise in LC-MSMS, peptide mapping, quantitative proteomics, HCP analysis, and intact mass analysis for biologics, antibodies, ADCs, small molecules, oligonucleotides, and COVID-19 test kits. I have supported the BLA submission of several anti-hemophilia biologics and contributed to the discovery and development of various drugs for cancer and immuno-oncology. I am passionate about driving innovation and excellence in the biopharma industry and advancing the health and well-being of patients.
