Mucoidy, a general mechanism for maintaining lytic phage in populations of bacteria

Published in FEMS Microbiology Ecology, 2020

This study demonstrates that overproduction of exopolysaccharides, “mucoidy”, allows bacterial populations to be resistant to lytic bacteriophage infection. We found that spontaneous reversion from the mucoid state to the susceptible non-mucoid state allows these phage-resistant bacterial populations to maintain lytic viruses without greatly affecting the bacterial population density.

Spinal V1 inhibitory interneuron clades differ in birthdate, projections to motoneurons, and heterogeneity

Published in eLife, 2024

This study characterizes the various subtypes (“clades”) of spinal V1 interneurons, describing their relative neurogenesis times, their distributions throughout the lumbar spinal cord, and their connections to motoneurons. It also investigates the molecular identities of further subdivisions within the Foxp2-V1 clade, and demonstrates that some of these Foxp2-V1s have connectivity that resembles reciprocal Ia inhibitory interneurons (IaINs).

Synchrony within Aβ mechanoreceptor subtypes governs signal propagation to primary somatosensory cortex

Published in bioRxiv (preprint), 2026

This study uses optogenetics with a fast channelrhodopsin variant (CatCh) to reveal how temporal patterns and synchrony of activity within Aβ low threshold mechanoreceptor subtypes control signal propagation to primary somatosensory cortex. We found that sustained cortical responses require synchronous activation of multiple Aβ SAI-LTMRs, while Aβ RAI-LTMRs drive robust cortical responses even with asynchronous activation.

V1 Interneurons Expressing Foxp2 are a Highly Heterogeneous Clade

Published:

Presented research findings on the heterogeneity of spinal V1 interneurons expressing the transcription factor Foxp2. This work contributed to our understanding of how V1 interneuron clades differ in their molecular identities and functional roles in the spinal cord.

Renshaw Cell Modulation of Reciprocal Inhibition and Motor Output

Published:

Presented ongoing research investigating how Renshaw cells modulate reciprocal inhibition pathways and influence motor output. This work combines in vivo electrophysiology with computational modeling to elucidate the functional roles of Renshaw cells in spinal motor circuits.
