Ulrich auf dem Keller, a leader in wound healing research and mass spectrometry-based proteomics technology, died September 1, 2023 at the age of 49.

Ulrich auf dem Keller

Born on April 5, 1974 and raised in Mülheim an der Ruhr, Germany, auf dem Keller received his undergraduate diploma in biochemistry in 2000. He then joined ETH, Zurich in the biology department under the mentorship of Pfizer Academic Award winner where he identified Nrf2 as a key player in the cellular stress response and studied Nrf-mediated gene expression in keratinocytes in the prevention of skin tumors. He obtained his Ph.D. in 2005. 

auf dem Keller moved to the Centre for Blood Research, Vancouver, Canada, in 2006 to join where he quantified changes in the proteome and analyzed the nature of protein amino termini analysis (N-terminome) using iTRAQ-TAILS technology and showed that loss of a single protease could perturb the proteolytic signaling network and enhance inflammation. 

In 2009, auf dem Keller started an independent lab in ETH, Zurich as a senior scientist and group leader.  He exploited the capability of iTRAQ-TAILS to exploring the substrate degradome of matrix metalloproteinase and translated his research to address complex proteolytic activities in healing impairments. In 2017, he moved to the section of protein science and biotherapeutics at Technical University of Denmark Bioengineering in Lyngby as a professor. He continued there until his death, exploring the quantitative proteomics approach in complex biological matrices.

auf dem Keller had more than 150 publications with 6,587 citations to date. He received a Herbert Tabor Young Investigator Award in 2011 from the ¾ÅÓÎÌåÓý for his studies of proteolytic events in the skin. 

Colleagues remember auf dem Keller as . He was instrumental in the overall growth of his department and his students. He spoke Latin and ancient Greek, had an interest in classical music and was an outstanding viola player. 

He is survived by his wife and two children.
