He joined the Bateman laboratory as postdoctoral associate in 2015. As research instructor, Barthélemy focuses his research on tau protein phosphorylation in Alzheimer's disease and tau modifications in other tauopathies. His research led to the discovery of new tau biomarkers for AD, including ptau217 in plasma/spinal fluid, and has provided new understanding on molecular mechanisms involved in tauopathies.

James Bollinger’s studies have focused on the development and application of novel analytical techniques for the profiling of enzymes of clinical relevance. Specifically, he has utilized the LC-ESI-MS/MS analytical platform to design reagents and assays that enable the sensitive and specific analysis of individual proteins as well as metabolite profiles derived from their enzymatic activity. In collaboration with multiple other labs, he has applied these assays to characterize relative abundance and kinetic profiles of several proteins with the greater intent of investigating in vivo roles in cellular homeostasis and disease progression. Current efforts in the Bateman lab are focused on LC/MS method development for; 1) the assessment of alpha synuclein protein turnover kinetics in human CSF 2) the assessment of Superoxide Dismutase 1 protein turnover kinetics in human CSF 3) the assessment of CNS amyloidosis through blood-based biomarkers 4) the assessment of Apolipoprotein E's role in the pathophysiology of neurodegenerative disease.
