The second paper I want to highlight was led my Izzy Grabski, where she developed a new method of "RNA Fingerprinting" to map transcriptional responses to perturbation dictionaries

Mapping transcriptional responses to cellular perturbation dictionaries with RNA fingerprinting
Single-cell perturbation dictionaries provide systematic measurements of how cells respond to genetic and chemical perturbations, and create the opportunity to assign causal interpretations to observa...

I wanted to highlight two recent papers from myself and colleagues! In the first, we develop a method, FlexPlex, that leverages the 10x Genomics Flex kits to capture RNA, intracellular protein and guide RNAs in single cells with high resolution multiplexing

Iterative, multimodal, and scalable single-cell profiling for discovery and characterization of signaling regulators
Cell signaling plays a critical role in regulating cellular state, yet uncovering regulators of signaling pathways and understanding their molecular consequences remains challenging. Here, we present ...

Excited (again) to see this paper finally in (pre)print! We did single-cell sequencing on our TSC model organoids and observed strong signatures of reactive astrogliosis (neat)- then we looked at resected patient brain tissue and saw the same thing! (More neat!)

Happy that my first paper from my Postdoc is out where we perform Phospho-seq, a single-cell ATAC-sequencing with intracellular protein quantification in human brain organoids:
