Research interests

Our primary research goal is to investigate what cellular determinants influence selective vulnerability or resistance in neurodegenerative diseases such as Parkinson’s disease. My lab aims to determine what factors make specific neuronal populations either more vulnerable or more resistant to neurodegeneration in order to identify potential targets for therapeutic intervention of these hitherto incurable diseases.

Secondly, my lab is interested in how psychostimulants such as amphetamines modulate synaptic transmission and hijack neural circuits that lead to drug addiction and dependence.

Lastly, my lab is interested in developing novel molecular tools for neuroscience research using genetic techniques that can be used to better visualize perturbations during ongoing neurodegeneration or after substance abuse.

Techniques, methods & infrastructure

Genetic mouse models (Cre recombinase expressing mouse lines; conditional knockouts), viral vectors (adeno-associated viruses; AAVs), CRISPR/Cas9 technology (knockouts and knock-ins), neuronal tract tracing, cell lines and primary neuronal cell culture (transfections, transductions), postmortem human brain tissue, molecular biology (cloning, site-directed mutagenesis, PCRs), biochemistry, (immunoprecipitations, pulldown assays, Western blots), histology (immunohistochemistry, mRNA in situ hybridizations in rodent and human brain sections), microscopy, pharmacology (radiotracer flux assays, behavioral pharmacology).
