We study the neurophysiology of olfaction to understand how brain functions emerge from local and long-range neuronal interactions.
Olfaction—the sense of smell—is a powerful model for probing sensory computation and decision-making. In rodents, it plays a central role in perception and behavior, offering a uniquely tractable window into how the brain transforms sensory input into meaningful actions.
Our research focuses on two main directions:
1. Circuit mechanisms of olfactory processing
We investigate how odor signals are represented and transformed at multiple stages of processing, especially in the olfactory bulb, the brain’s first processing stage for smell. Using physiological and computational approaches, we ask: how are odor features encoded, filtered, or conditioned, and what circuit mechanisms generate these neural codes?
2. Local and long-range interactions in context-dependent processing
We explore how behavioral context—such as reward, engagement, and task demands—dynamically modulates olfactory processing. By combining sophisticated behavioral paradigms with electrophysiology, optical imaging, and optogenetics, we dissect how feedback and neuromodulatory inputs flexibly tune circuit function.
Our work integrates quantitative behavior, large-scale physiology (including Neuropixels recordings, two-photon imaging, and patch-clamp), and precise circuit manipulations to reveal how sensory computations adapt to guide decisions.
We are aslo involved in various collaborations with scientists across disciplines. Examples include a project on the human evolution (how a modern human-specific amino acid change in the enzyme ADSL affects brain and behaviour), and development of devices like microLED array for optogenetics.
