Marisa Joubert is a Senior Principal Scientist and Leader of the Attribute Impact Group in the department of Process Development at Amgen Inc (Thousand Oaks, CA).  She has been at Amgen since 2008 as a pharmaceutical scientist in drug product development.  Her group evaluates the impact of biotherapeutic attributes on the safety and efficacy of drug products.  She is also the team lead of a multi-department cross-functional working group that assesses the risk of immunogenicity of key product quality attributes.  She has received several awards for this work including the 2019 Innovation Award and the 2018 Excellence in Operations Award from Amgen, and the 2015 Ebert Prize from the American Pharmacists Association.  Prior to joining Amgen, she was a Senior Researcher at the Council for Scientific and Industrial Research in Pretoria, South Africa, where she evaluated novel therapeutic agents for treating HIV-1.
