Research Interests:

  • Alzheimer’s disease and Parkinson’s disease and related proteinopathies: amyloidopathies, tauopathies, synucleinopathies.
  • Cocaine abuse and addiction.
  • Animal models utilizing genetic and pharmacological manipulations.
  • Omics and bioinformatics approaches for the identification and validation of novel mechanisms that underlie memory and cognitive deficits induced by aging, neurodegenerative disease, and drug abuse.
  • Nicotinic acetylcholine receptors, nuclear receptors (PPAR), ERK MAPK, CREB, CBP, calcineurin, protein-protein interactions.

Selected Publications:
Beginning with seminal work establishing amyloid-β (Aβ)-nicotinic acetylcholine receptor (nAChR) interaction that laid the foundation for a series of publications elucidating the role of α7 nAChRs in early Alzheimer’s disease (AD) as well as mechanistic discoveries implicating calcineurin and peroxisome proliferator-activated receptor–γ (PPARγ) in early AD hippocampal dysfunction. Subsequent work has investigated temporal cortex circuit disruptions and translational interventions to normalize intrinsic properties, synaptic plasticity, and memory.  Parallel activities have generated novel tools and technologies and broadly cited reviews that have helped guide the field of neurological disease including AD.
