Dr. Erwin Schoof did his PhD on colorectal cancer metastasis at the Institute of Cancer Research in London and the Technical University of Denmark. For his Postdoc, he moved to Canada to study cancer stem cells in the lab of John Dick, and to establish proteomics on small cell populations. After 2 years, he relocated to the lab of Bo Porse, where he is currently wrapping up his work on leukemia stem cell proteomics and the normal human blood hierarchy. Throughout this process, he spent quite some effort to establish single cell proteomics workflows, which is now ready to tackle some highly critical biological questions. Currently, Dr. Erwin Schoof heads the DTU Proteomics Facility while pursuing an academic career in cancer stem cell biology. He holds a joint appointment at DTU and the University of Copenhagen, focusing on normal and malignant hematopoiesis.
