I am most interested in the sensory mechanisms required for animal navigation and particularly revealing the sensory mechanism of animal's magnetic sense. My current research addresses the following questions: 1) how can migratory and sedentary birds use the earth's magnetic field for navigation? 2) where are the animal magnetosensory cells located in the body and what is their perceptive mechanism? 3) Can we expand a line-up of model species for studying magnetoreception? The range of methods and techniques I use: orientation tests in round arenas (birds, fish), radio transmitters, geolocation telemetry, stable isotopes, micro-surgeries to deactivate magnetic and olfactory senses, magnetic field manipulations using magnetic coil system and magnetic pulsing.
