Research interests

We are interested in the Development and function of sensory systems.
A major focus is the Drosophila larva, primarily the sense of vision and gustation.

Functionality of sensory neurons is defined by the sensory receptor gene expressed.
In case of photoreceptor neurons in the eye these are Rhodopsins, in gustatory neurons these are gustatory receptors, both are coding for G-protein coupled receptors (GPCRs).
– How do sensory neurons choose which sensory receptor to express?
– That is the regulatory logic controlling GPCR expression?

In the larva the sense organs are comparably simple: the eye consists of 12 photoreceptors (4 blue-sensitive, 8 green-sensitive), the gustatory organ (primarily terminal organ) consists of about 32 gustatory neurons.
– Which sensory stimuli are perceived by which sensory neuron?
– What are the target neurons making up the first step in visual and gustatory circuits?
