I'm thrilled to share that I've started as an Assistant Professor in Biological Sciences and the Oceans Research Center at Lehigh University!
I'm building a group in evolutionary genomics to study the origin of animals, and to use those concepts to better understand human disease.

How ancient are the building blocks of animal sensory systems?
Key components of animal sensory systems evolved before animals. We find that choanoflagellates possess diverse & spatially segregated TRP channels, pointing to ancient origins of sensory specialization.

Our latest: combining single-cell RNA-seq from 16 species and HCR validation, we show that monoaminergic neurons share a conserved transcriptional identity across Bilateria. In contrast, we find no evidence for this program in non-bilaterian metazoans. www.biorxiv.org/content/10.1...

The evolutionary conservation of cell types over deep time has long been theorised but remains difficult to demonstrate. Monoaminergic neurons, which produce molecules such as serotonin and dopamine, ...
