Our lab is focused on high content drug screening, assay development and the combination of electrophysiological, imaging and genetic assays to deeply interrogate human induced pluripotent stem cell (hiPSC)-derived neurons. Our team has developed novel techniques for screening and analyzing 3D organoids developed from hiPSCs to model cortical development in autism.
My graduate work in the lab of Dr. Scott Thompson at the University of Maryland, School of Medicine focused on single cell approaches to study the relationship between synaptic morphology and synaptic plasticity at the tripartite synapse in the hippocampus. To do this, I used a combination of live-cell imaging and advanced techniques in electrophysiology, including single-synapse microphotolysis combined with gene gun transfection in organotypic hippocampal slice cultures. We found that the expression of the ephrinA4 receptor on astrocytes affected their morphology and subsequent synaptic activity.
As a postdoctoral fellow at The National Institutes of Health in Dr. Dax Hoffman’s lab, I focused on real-time imaging techniques such as in vivo two-photon microscopy, FRAP, in vivo single-cell electroporation and calcium imaging. This work included the creation and use of track-tracing trans-synaptic rabies virus and Sindbis virus designed to express GFP-tagged Kv4.2 channels. By using two-photon imaging at single dendrites we were able to demonstrate that Kv4.2 channels are differentially trafficked at different regions along the apical dendrite of neurons during basal activity and upon stimulation in a PKA-dependent manner.
Because of my interest in human induced pluripotent stem cells (iPSCs) and their application in disease modeling, I joined Dr. Scott Noggle at The New York Stem Cell Foundation and developed a number of protocols surrounding the use of a three-dimensional iPSC culture system called a serum-free embryoid body (SFEB). Using SFEBs, we were able to perform electrophysiology combined with calcium imaging as well as develop a protocol to create interneurons that shared transcriptional histories and functional properties with those that were born in the caudal ganglionic eminence.
My approach at The Hussman Institute for Autism involves leveraging the sum of these experiences to develop a robust human cellular model of autism suitable for preclinical drug discovery and therapeutic development.
