Pritish Chakravarty | External PhD Student

I’m doing a PhD at EPFL in bio-engineering, and am working in collaboration with the wonderful team at PopEcol to investigate dispersal in a cooperative breeder (meerkats!) using inertial sensors. A tri-axial accelerometer is a type of inertial sensor that records acceleration in three dimensions – up, left and forward. Accelerometers put on animals reveal movement signatures of common behaviour. Characterising these behaviour signatures mathematically to later recognise them in a continuous stream of recorded acceleration would permit remote or virtual ‘observation’ of the animal. I am interested in developing behaviour recognition algorithms and using them to detect behaviour-state changes in dispersing meerkats. The combination of the knowledge gained through this animal-borne ‘virtual eye’ with theoretical models, long-term individual-based data on within-group demography and group movements, and population genetic analysis, could help unravel the mechanism and patterns of dispersal.

It would seem that I enjoy living at the foothills of mountains – from those of the Himalayas (Chandigarh), I have now moved to those of the Alps (Lausanne). And I started a PhD, so there are three data-points that fit this theory. Anyway, I’m an avid table tennis enthusiast and like how one has to attain enlightenment to play it properly. I dabble with the guitar and poetry. I thoroughly enjoy travelling with field biologists – seemingly random patterns in the sand turn into a herd of wildebeest that had been passing by a few hours earlier!
