Welcome to the website of the Ackels lab. Our overarching goal is to answer questions on how the dynamics of the external world are encoded in the brain and how they inform behaviour.

We are a newly formed lab and are currently hiring at all levels!
See our open positions and get in touch if you are interested in joining us!


Making sense of the world


Sensory input across modalities is highly dynamic and continuously confronts the brain with the task of making sense of the external world. This is particularly true for sensory systems that are subjected to a high amount of information. How does the brain do this? How does it use this information to make decisions?

Information about space from time


Olfaction is a key sense that many species depend on for survival, for example to locate food sources and mating partners or to avoid encountering predators. Olfactory cues are especially useful, as they provide information over a large range of distances, in the absence of visual cues.

Natural odours form temporally complex plumes that are characterised by rapid fluctuations in odour concentration. The complex temporal dynamics of odour plumes carry spatial information about the odour landscape. They may form a vital sensory component for animals navigating an environment, particularly for nocturnal animals such as mice or rats. The sense of smell is thus being increasingly acknowledged to be a high-bandwidth modality that has access to the complex temporal structure of natural odour plumes, creating a paradigm-shift in olfactory sensory neuroscience.

Understanding how the spatial information carried by odour plumes is used by mammals to navigate their environment on the cellular, circuit and behavioural level constitutes the primary research focus of the lab.

The PI


Prof. Dr. Tobias Ackels

University of Bonn, IEECR

Tobias was born in Germany and has just started to set up his laboratory as a group leader at the Institute for Experimental Epileptology and Cognition Research (IEECR) as part of the University of Bonn Medical Center. He was awarded an ERC Starting Grant for his project “TempCOdE: Temporally complex odor information encoding”.

Tobias did his postdoc at the Francis Crick Institute in London. He received his Diploma in Biology from RWTH Aachen University, where he also completed his PhD studies in 2015 in the Department of Chemosensation. His doctoral research mainly focused on signalling mechanisms in the olfactory system. Supported by a postdoctoral fellowship from the DFG, he moved to the laboratory of Prof. Andreas Schaefer at the Francis Crick Institute, invigorating his interest in the investigation of how natural sensory stimuli are perceived and processed in the mammalian brain.

His laboratory investigates these mechanisms on the cellular and network level using physiological and behavioral techniques.
