Invited Speaker – Prof. Volodymyr Kruglyak

We are delighted to announce that Prof. Volodymyr Kruglyak, a Senior Lecturer at the University of Exeter has accepted our invitation to be an invited speaker at IONS Exeter.

His talk will be titled “Ultrafast response of thin metallic magnetic films to optical excitation: Magnonics, magneto-acoustics or optics?“.

His primary research interests lie in understanding the ultrafast spin dynamics at the nano-scale, and then in exploring ways to exploit spins and spin waves (magnons) in practical applications, e.g. within magnonics and magnetic data storage technologies.

Invited Speaker – Dr. Joshua Einsle

We are delighted to announce that Dr. Joshua Einsle, a Post-Doctoral Research Associate at Imperial College London has accepted our invitation to be an invited speaker at IONS Exeter.

His talk will be titled “Nanomagnetic properties of the cloudy zone: a Fe-Ni alloy alternative to rare-earth permanent magnets“.

Joshua’s research focuses on understanding the relationship between paleomagnetic measurements and the underlying nanoscale magnetic signal carriers.  In order to model and discuss the stability of magnetic signals through time one needs to fully characterise the chemical and crystallographic environment that a sample exists in.  He applies a variety of electron microscopy techniques (Focused Ion Beam Tomography, EDS STEM tomography, Holography, and Scanning Precession Electron Diffraction) combined with other techniques from materials science such as atom probe tomography and x-ray computed tomography. By combining these multiscale approaches he bridges length and dimensional gaps in the understanding of macroscopic magnetic measurements. 

Invited Speaker – Dr. James O’Keeffe

We are delighted to announce that Dr. James O’Keeffe, a post-doctoral researcher in the group of Jenny Read, a Professor of Vision Science at the Institute of Neuroscience at Newcastle University.

His talk will be titled “From mantis to machine: A new bio-inspired algorithm for machine stereopsis“.

James’ current work involves investigating new methods for machine stereopsis. It aims to understand 3D vision (stereopsis) in the praying mantis, the only invertebrate known to have this ability, and compare it with 3D vision in humans and in machines. This will shed new light on the constraints governing 3D vision, how 3D vision evolved, and how we can engineer efficient 3D vision ourselves. He has previously worked on evolving immune systems for swarm robots at the University of York and autonomous unmanned air systems at Qinetiq.

Invited Speaker – Dr. Jessica Boland

We are delighted to announce that Dr. Jessica Boland, Lecturer in Functional Materials at the University of Manchester has accepted our invitation to be an invited speaker at IONS Exeter.

Her talk will be titled “Terahertz lights up the nanoscale: exposing the optoelectronic properties of novel quantum materials for device applications“.

Dr. Boland is a recent recipient of the Institute of Physics Jocelyn Bell Burnell Medal and Prize.

Dr. Boland’s research interests are focused on revealing the ultrafast carrier dynamics of novel nanomaterials via terahertz spectroscopy. She is an expert in ultrafast optical-pump terahertz-probe spectroscopy – a non-contact technique for directly extracting the dielectric function and photoconductivity of a material. She has utilised this technique on semiconductor nanostructures, demonstrating accurate characterisation of their key optoelectronic properties, including carrier mobility, carrier lifetime and both intrinsic and extrinsic carrier concentration. She has also utilised near-field scattering-type midinfrared microscopy to demonstrate increased spatial resolution down to the nanometre-scale, performing nanotomography on topological insulator thin films. She is currently applying this technique to the terahertz range, combining scattering-type near-field optical microscopy with optical-pump terahertz-probe spectroscopy to provide a surface-sensitive probe of electrical conductivity and photoconductive with sub-picosecond temporal and nanometre spatial resolution. Her research focuses on exploiting this technique alongside far-field terahertz spectroscopy to reveal the ultrafast carrier dynamics of topological insulators, 2D materials and III-V nanowires.
