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.

Samir Lopez Chahin has a BS in mechanical engineering and a master’s degree in engineering management from Washington University, along with a BS in physics from Kansas Wesleyan University. He joined the lab in the beginning of 2021 to assist in bench work from ongoing projects, develop automated processes to improve throughput and quality of experiments, optimize data analysis and results and assist the team in decision making. His main goal will be to shorten the cycle time it takes from starting an experiment to having results while maintaining quality at its maximum.

Brendan Lucey is an associate professor of neurology.  He is the Sleep Medicine Section head and see patients at the Washington University Multidisciplinary Sleep Medicine Center.  Lucey is currently funded by a K76 Beeson career development award from the National Institute on Aging to study sleep and human amyloid-beta kinetics.  The primary focus of his work is to investigate if sleep disturbances may serve as a marker for Alzheimer’s disease and if treatment of sleep disturbances may prevent or delay the onset of Alzheimer’s disease.

Justin Melendez received his PhD in genetics and genomics from Washington University in St. Louis where he worked on developing tools for molecular biology and sequencing technologies. His work in the Bateman lab focuses on studying the connection between human aging and neurodegenerative disease, understanding how and why we age and developing therapeutic interventions to extend human life and health span.
