Invited Speakers

We have welcomed the following speakers to the Laser Analytics Group:

14. February 2018

 Christian Eggeling

George Malliaras

30. January 2018

George Malliaras from the Department of Engineering will present his work on interfacing with the brain using organic electronics.

One of the most important scientific and technological frontiers of our time is the interfacing of electronics with the human brain. This endeavour promises to help understand how the brain works and deliver new tools for diagnosis and treatment of pathologies including epilepsy and Parkinson's disease. Current solutions, however, are limited by the materials that are brought in contact with the tissue and transduce signals across the biotic/abiotic interface. Recent advances in organic electronics have made available materials with a unique combination of attractive properties, including mechanical flexibility, mixed ionic/electronic conduction, enhanced biocompatibility, and capability for drug delivery. I will present examples of novel devices for recording and stimulation of neurons and show that organic electronic materials offer tremendous opportunities to study the brain and treat its pathologies.

Thomas Huser

Professor Thomas Huser from the Biomolecular Photonics Group at the University of Bielefeld will present his latest efforts in unveiling and following structural changes of cellular nanopores in living cells by GPU-enhanced super-resolution structured illumination microscopy.

During the last decade a number of optical imaging techniques have been developed that utilize different physical or photochemical means to overcome the optical diffraction limit. Any single technique is, however, often not well suited to address all needs of a specific biomedical research problem. Single molecule localization microscopy, for instance, provides very high spatial resolution and quantification, but requires a considerable amount of time to conduct which is often not ideal for addressing imaging needs in live cell studies. Super-resolved structured illumination microscopy, on the other hand, is well suited for live cell imaging, but its spatial resolution improvement is, in most cases, limited to a factor of two. In my research group, much of the research interests are driven by specific biomedical needs, e.g. resolving the structure and dynamics of nanopores in the cellular plasma membrane, or investigating the mechanisms and specific sequence in the transmission of virus from infected cells to uninfected cells. To best address these issues from all perspectives, we typically utilize a suite of multimodal methods, e.g. the combination of optical tweezers with optical nanoscopy, or the combination of temporal and spatial methods of improving the spatial resolution and select the best possible method for each research question.

Melody Clark

Professor Melody Clark has a genetics degree and PhD from London University. After a string of short-term post doc contracts working on areas ranging from plant chromosomes to the high-profile Japanese pufferfish genome project, she finally landed a job as Project Leader at the British Antarctic Survey (BAS) in August 2003.

She currently leads the Adaptations group and will talk about how animals have adapted to life in freezing oceans and how they respond to climate change. In particular, the paradox of the incredible biodiversity in the Southern Ocean and the cellular level problems of protein folding at such low temperatures.

  •  Dr. Balpreet Singh Ahluwalia

30. August 2017

Balpreet Singh

Dr. Ahluwalia is working on optimizing and fabricating high-refractive index contrast waveguides for lab-on-a-chip applications including optical trapping, propulsion, sensing, and superresolution microscopy.

He talked about Nanoscopy over millimeter scale using photonic chip” and provided us with an overview of photonics chip-based dSTORM, chip-based light fluctuating optical nanoscopy, and chip-based SIM (structured illumination microscopy). By retrofitting photonic chips to any standard optical microscope it is possible to convert it into an optical nanoscope (dSTORM, SIM, etc). Chip-based optical nanoscopy enables sub-100 nm optical resolution over extra-ordinary large field-of-view (millimetre scale). This will enable application of high-throughput chip-based optical nanoscopy in diagnostics and pathology.

  •  Dr. Marcel Mueller

12. July 2017

Marcel Mueller

Marcel Müller studied physics and worked a post doc at Bielefeld University where he developed the widely known fairSIM plug-in for ImageJ. He then continued his work in Oxford to include 3D-SIM capabilities in software package and started a new post doc in the Dedecker lab in Leuven to work on Multifocus 3D-SIM.

  •  Prof. Anatoly Grudinin

7. July 2017

Anatoly Grudinin

Anatoly Grudinin started his work in the area of fiber optics in 1980 as one of the first researchers who studied nonlinear properties of silica fibers and nonlinear dynamics of picosecond and femtosecond pulse evolution in single-mode optical fibers. In 2003 Anatoly left his professor's chair at the Optoelectronics Research Centre at University of Southampton and founded Fianium, a fiber laser company focused on development and volume manufacturing of ultrafast fiber lasers for bio-medical and industrial applications. 

In this talk “Ultrafast fiber lasers: the hunt for a killer application” he reviewed latest developments and applications of picosecond and femtosecond fiber lasers. Motivated by rapid improvement of performance and attractive features such as compactness and low ownership cost, ultrafast fiber lasers now challenge conventional DPSS ultrafast sources across numerous industrial sectors. They enable development of unique sources such as supercontinuum lasers capable of enabling scientific discovery and replace incumbent illumination technologies within industrial instruments and systems.

16. June 2017

Morten Bache

Morten Bache is associate professor in the Nonlinear Optics and Biophotonics Section at DTU Fotonik and Ultrafast Nonlinear Optics team leader. He is an expert in theoretical and numerical modeling of nonlinear optical phenomena with a vast experience in realistic numerical modeling of experiments. During his Ph.D. and a 3 year postdoc in Italy he worked on nonlinear and quantum optics and on ultra-fast spatial and temporal phenomena in quadratic nonlinear materials. His current research concerns ultra-fast femtosecond nonlinear optics in fibers and nonlinear crystals.

12. June 2017

Patrick Salter

Dr. Salter is a W.W. Spooner Research Fellow at New College in Oxford and conducts research into photonic engineering,    particularly adaptive optics systems, laser microfabrication and diamond technology. 

​He gave a talk entitled "​Adaptive optics for femtosecond laser writing inside transparent materials" in which he described methods of writing waveguides into CVD diamond materials and applications. 

22. May 2017

Emmanuel Derivery

Dr. Derivery is a group leader at the Laboratory of Molecular Biology in Cambridge. He pioneers ground breaking new imaging and biophysical tools to study symmetry breaking during development.

Dr. Derivery talked about polarized endosome dynamics by spindle asymmetry during asymmetric cell division. During asymmetric division, fate determinants at the cell cortex segregate unequally into the two daughter cells. It has recently been shown that Sara signalling endosomes in the cytoplasm also segregate asymmetrically during asymmetric division. Dr. Derivery and his group unravelled the molecular mechanism of this asymmetric dispatch of signalling endosomes.

11. May 2017

Ali Hassanali

Dr Hassanali is a senior investigator in the Condensed Matter and Statistical Physics section (CMSP) at the International Center for Theoretical Physics (ICTP) in Trieste, Italy.

Dr Hassanali talked about theoretical and computational investigations of quantum and microscopic interactions in molecular systems using ab initio molecular dynamics simulations. Dr Hasanali's team performed ground breaking molecular dynamics and DFT simulations to explain our intriguing discovery that the amyloid systems develop an intrinsic fluorescence in the UV-Vis range that is independent of aromatic residues.  His simulation demonstrated that frequent proton charge exchanges can take place between adjacent C- and N- Termini in amyloids.
