Research Interests

My fascination with sensory neuroscience began with my childhood observations of mosquitoes swarming at dusk on long Summer days. The female mosquito’s high-pitched whine (all too familiar to victims of their bites) turns out to be necessary for male mosquitoes to locate them. The remarkable auditory sensitivity of mosquitoes is underpinned by ~16,000 neurons, jam-packed into a tiny structure: the Johnston’s organ. My imagination was captured by these mechanosensory neurons and sparked a question which has guided my research journey ever since:  How do insect auditory neurons transduce nanoscale displacements into neural potentials?
To pursue this question I migrated to the renowned Kloppenburg lab in Cologne to learn the art of patch-clamping: a powerful electrophysiological tool for understanding the inner workings of neurons. I gained further experience in the world-famous Göpfert lab in Göttingen which utilised the fruit fly to understand the molecular basis of mechanotransduction.
Studies of auditory neurons in insects were hampered by a lack of electrical recordings of the fundamental mechanical-to-electrical step. To address this gap in knowledge I turned to the locust, which has large accessible auditory neurons, which I brought the powerful patch-clamp technique to bear. I currently work in the fascinating lab of Tom Matheson studying the cellular basis of mechanotransduction in the locust ear.
