• Featured in PennToday: New research describes an innovative method for identifying molecules that can help track the progression of Parkinson’s disease. Conducted by scientists in the labs of E. James Petersson of the School of Arts & Sciences and Robert Mach and Virginia Lee of the Perelman School of Medicine, this proof-of-concept study could change the paradigm for how researchers screen and test new molecules for studying a wide range of neurodegenerative diseases.
