We develop and apply new imaging tools (including spatial transcriptomics and genomics) to understand how gene regulation information propagates across scales from the molecular events within the nucleus to the organization of cells into tissues and organs, up to the scale of animal behavior. We aim to push the MERFISH technology to image a the level whole organ image as well as integrate the technology with other cutting edge neuroscience tools (retroviral tracing, calcium imaging, etc.).
Current projects in the lab include identification of the molecular basis of Neuroregeneration, determining the transcriptomics/connectivity role of the Thalamus within the Opioid addiction/withdrawal circuitry, developing a quantitative spatial readout for Huntingtons CAG expansions. On our technological development front, we are working on expanding our imaging area by an order of magnitude (MERFISH+), MERFISH imaging of thick tissue (200um+) with epifluorescence microscopes, MERFISH-based CRISPR pooled screening, and generating a retroviral tools for enabling MERFISH compatible single cell spatial connectomics.
We also am working on a web browser based MERFISH visualizer that runs locally and provides the with quantifications on their data (courtesy of Kresna Jenie) which can be found at https://www.merfisheyes.com/
