Research Areas
Antimicrobial peptide signaling in urinary tract infections
We are interested in how antimicrobial peptides contribute to urinary tract immunity by activating receptors on immune cells and sensory neurons.Host-microbe interaction in the skin
We use mouse and bacterial genetics to understand how S. aureus interacts with antimicrobial peptides in the mammalian skin.Neuro-immune crosstalk in psoriasis
We try to understand how defensins facilitate neuro-immune crosstalk and cause psoriatic itch.Publications
