Professor Mika Pettersson, Nanoscience Center, Department of Chemistry, University of Jyväskylä: “Nonlinear optical interactions of  femtosecond laser pulses with graphene: patterning, imaging and ultrafast dynamics.
Bio: Mika Pettersson is the vice head of Nanoscience Center, University of Jyväskylä. He is an expert in optical spectroscopy. He received PhD degree in physical chemistry at the University of Helsinki. His thesis work handled preparation and spectroscopy of novel rare gas compounds and the work later led in 2000 to the discovery of so far the only known chemical compound of Argon – HArF. He spent a post-doctoral period at the University of California, Irvine during 2000 – 2001 with Prof. V. A. Apkarian, working on time-resolved coherent anti-Stokes Raman scattering (CARS) of molecules isolated at low temperature matrices. Since 2003 he has been at the University of Jyväskylä focusing on spectroscopy of nano-objects. His current interests include graphene and small ligand-protected gold nanoclusters.


Dr. Hans Peter Herzig Professor at the Ecole Polytechnique Fédérale de Lausanne (EPFL): “Bloch surface waves for 2D optics”
Bio: Hans Peter Herzig received his diploma in physics from the Swiss Federal Institute of Technology in Zürich, Switzerland, in 1978. From 1978 to 1982 he was a scientist with the Optics Development Department of Kern in Aarau, Switzerland, working in lens design and optical testing. In 1983, he became a graduate research assistant with the Applied Optics Group at the Institute of Microtechnology of the University of Neuchâtel, Switzerland, working in the field of holographic optical elements. In 1987, he received his PhD degree in optics. From 1989 to 2001 he was head of the micro-optics research group in Neuchâtel. From 2002 to 2008 he was a full professor and head of the Applied Optics Laboratory at the University of Neuchâtel. Professor Herzig joined the faculty at EPFL in January 2009. He has been President of the European Optical Society (EOS). His current research interests include refractive and diffractive micro-optics, nano-scale optics and optical MEMS.

Dr. Markus Metsälä, University of Helsinki: Optical measurements of exhaled breath – volatile biomarkers in non-invasive medical diagnosis and monitoring.”
Bio: Markus Metsälä is a university lecturer at the Department of Chemistry, University of Helsinki. He received his PhD degree in physical chemistry at the University of Helsinki in 2006. For his PhD thesis he worked on the development of sensitive optical spectroscopic techniques for molecular vibrational overtone spectroscopy. In 2007 he spent a year as a post-doc in the group of Prof. Gerard Meijer at the Fritz-Haber-Institute in Berlin, working on the Stark deceleration of molecular beams to produce cold samples of polar neutral molecules. Since then he has worked at the University of Helsinki. His current research interests revolve around the use of exhaled breath analysis for non-invasive medical diagnostics and monitoring. In these studies he employs both laser spectroscopy and mass spectrometry.



Professor Jens Pahnke, University of Oslo, Norway, (“Dementia and the need to characterise brain lesions in vivo using NIR and fluorescent probes”
Bio: Jens Pahnke is head of the Department for Neuropathology and president of the Scandinavian Society of Neuropathology. He has also a background in electronics and HF plasma heating and worked at JET Joint Undertaking in Abingdon (UK) 25 years ago. Later he studied both medicine (Staatsexamen) and molecular biology (Diploma) at the University of Greifswald, Germany (1994-2000). He holds a PhD degree in Molecular Biology/Neuroscience of the University of Rostock, Germany (2004). Since 2008 he is a specialist in Neuropathology working with daily routine diagnostics of muscle diseases, brain tumours, and brain autopsies.His research lab focusses on neurodegenerative diseases with special emphasis on the function of the blood-brain barrier and also the use and development of new methods for functional assessment of barrier transporters and treatment. His team discovered new a mechanism for the treatment of dementia and works in a translational setting with in vitro cell models, mouse models, and also patients. The lab develops humanised mouse models for molecular research that enables better translation into clinics . With respect to imaging and optic-active probes his interest lies in the detection of different amyloid-beta species and optic transcranial imaging of the brain to be able to describe the development of toxic aggregates of amyloid-beta as plaques in the brain in greater detail. One current project is aiming on the use of light for functional switching of the ABC transporter kinetics in brain vessels of mice.
