A New Era In Alzheimer's Research with Sarah DeVos

Do you have a question you'd like answered on a future episode of Translating Proteomics? Send it to translatingproteomics@nautilus.bio!

On this episode of Translating Proteomics, host Andreas Huhmer discusses advances in Alzheimer’s research with special guest and Curie Bio Drug Maker in Residence, Sarah DeVos Ph.D. Their conversation focuses on:

• The impact of molecular diagnostics on Alzheimer’s research
• Recent Alzheimer’s drug approvals
• The future of Alzheimer’s research

*Small edit on Sarah's background - She did her graduate work at Washington University in St. Louis and a Postdoc at Massachusetts General Hospital*
