Type of event: 

Seminar

Speaker: Dr. Itia Favre-Bulle

Since the invention of Optical tweezers in 1986 by Arthur Ashkin (2018 Nobel prize winner), optical trapping has been an extremely powerful tool for a number of wide ranging applications. From the manipulation of fluorescent nano-diamonds to chromosomes, cells and bacteria, optical trapping can now successfully elucidate the intricacies of complex and challenging biological systems. In this talk I will present our recent studies on swimmers such as bacteria and sperms but also how we investigate challenging biological systems such as the vestibular system in zebrafish for Neuroscience.

 

Biography: 

Dr. Itia Favre-Bulle completed her Engineering and Master degrees in Physics at the University of Strasbourg, France and her PhD in Biophysics at the University of Queensland. Her research involve the study of light scattering, light shaping and the optical manipulation of complex biological systems and micro-machines. She developed and combined various optical systems to shape light in order to perform the manipulation and the measurement of forces on various biological systems (from micro-sized particles and single cells to ear-stones in zebrafish) as well as perform arbitrary illumination of brain tissue with holographic illumination for optogenetics and neuroscience.
