Peter de Keizer, PhD
Managing director
Peter de Keizer is the founder and managing director of Cleara Biotech B.V. He has 10+ years experience in valorization, intellectual property and preclinical research and development. He is and associate professor “Senescence in Cancer and Aging” at the University Medical Center Utrecht, the Netherlands. Peter was trained as a molecular biologist at Utrecht University and Harvard Medical School / Mass General Hospital, Boston, MA, USA (2004). He performed is PhD in 2009 in the field of FOXO signaling, knowledge he employed during his postdoctoral work at the Buck Institute for Research on Aging in Novato, CA, USA (2012) to develop the first compounds to eliminate senescent cells: FOXO4-based peptides. In 2017, he showed the translational power eliminating at least some types of senescent cells in mice, which resulted in a restoration of tissue homeostasis in models for aging and chemotoxicity (Cell, 2017; cited >700 times). In 2018, he joined the UMC Utrecht, the Netherlands, to investigate subtypes of senescence, where he became associate professor in 2020. Peter has been awarded several awards for his work on targeting senescence, including “talent extraordinary”(2013), ambassadorship of the Dutch Cancer Society (2017). He is a recurring guest in mainstream media on topics of aging and/or senescence and is regularly approached by policy markers for advice. He is an active member of the European Association for Cancer Research and the International Cell Senescence Association. Through Cleara Biotech B.V. he is dedicated to merge academic knowledge on senescence subtypes to develop new compounds and bring these to the clinic against late state cancer and chronic diseases.
