James Bollinger, Ph.D.

Dr. 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 triple-quadrupole 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.

Kaylan Tripathy
Kaylan Tripathy is currently an MD/PhD student in the Neuroscience graduate program at Wash U. Previously, he worked with Drs. Virginia Lee and John Trojanowski at Penn on the role of TDP-43 in neurodegenerative disease pathogenesis, and with Drs. Brad Schlaggar and Steve Petersen at Wash U on cortical parcellation in children using resting state functional connectivity. Kaylan’s summer 2016 rotation project was to refine a purification scheme and apply newer mass spectrometry approaches to study the full range of amyloid beta proteoforms found in human cerebrospinal fluid. Prior and ongoing work in the lab has looked for these proteoforms by studying intact (undigested) a-beta in Alzheimer’s disease patient brains. His project aimed to take a top-down approach to look for these species by studying intact a-beta in human CSF. The goal is to eventually identify a fingerprint for Alzheimer’s disease, wherein valuable diagnostic and prognostic information can be extracted from the levels of various a-beta proteoforms in a patient’s CSF. In the process, we would also glean valuable information about the pathophysiology of Alzheimer’s disease. Outside of the lab, Kaylan volunteers with a few community service projects focused on medical care and teaching, and he also sings and plays guitar as part of a student band.
