Check out my latest work with @AMMmatheson on the circuits controlling goal-directed navigation in flies!

How do animals navigate to goals in their environments? In the Nagel lab’s latest pre-print @ajlanz2 and I explore how the brain locates the most important goal, food. We identify a neural circuit for wind-guided olfactory navigation in Drosophila. biorxiv.org/content/10.1101/…
A neural circuit for wind-guided olfactory navigation

A neural circuit for wind-guided olfactory navigation

To navigate towards odor in a turbulent environment, animals integrate odor value cues with wind direction cues. The central neural circuits subserving this behavior are unknown. Here we used...

A vector-based strategy for olfactory navigation in Drosophila

Nature - Using a virtual reality system, experiments in Drosophila show that flies use memory mechanisms to navigate along the boundary of an odour plume and track the source of a smell.

Thrilled to share that I’ll be starting my lab in the Kresge Hearing Research Institute @UMichOto in May! We study how the brain turns gravity signals into stable movement → zhulab.fish (yup, proudly a #zebrafish lab🐟) If you're interested, get in touch! #newPI

We are looking for a postdoc to lead a new project in olfactory diagnostics: can we detect human diseases using the mammalian olfactory system as supersensitive, broadband chemical detector? A lot of imaging, data analysis and gas chromatography…. rinberglab.com/positions

At first glance, this review might look extremely niche, but I think it speaks towards a much broader question: how do animals (and the brain) navigate towards ambiguous goals in space? And, how are these strategies shaped by the animals' environment?

Seizures are just hyperexcitability, right? Think again! Inhibition is everywhere in the brain, but how does it change during a seizure? We re-imagined a new approach to assay neuronal excitability using all-optical interrogation in vivo. Check it out! 👇 biorxiv.org/content/10.1101/…
