Bio & Medical Sciences

  Teng-Leong Chew: Imaging Life with the Emerging Frontiers in Microscopy at the Advanced Imaging Center, HHMI Janelia Research Campus

How optical physics, computer science, tissue engineering and biosensor development converge to enhance the study of cell biology has remained Chew’s research focus. Through his own research in cancer invasion and his responsibilities in building centers for advanced microscopy, Chew has sought to create platforms where interdisciplinary collaboration can elevate life science research.  It was with this philosophy that he joined the Howard Hughes Medical Institute Janelia Research Campus in 2014 to serve as the inaugural director of the Advanced Imaging Center, where he leads the effort in building the unique collaborative imaging center that serves as the gateway through which the wider scientific world can access Janelia’s cutting-edge microscopy capabilities. Before his move to Janelia, Chew led the Center for Advanced Microscopy and the Nikon Imaging Center at Northwestern University Feinberg School of Medicine in Chicago. There he was also appointed as the Director for University Imaging Resources, overseeing the overarching strategy in building integrated imaging infrastructure across all seven imaging centers within Northwestern University.

  Adam P. Hitchcock: Advanced Materials Analysis by Synchrotron-based Soft X-ray Microscopy

Adam Hitchcock, Fellow of the Royal Society of Canada (FRSC), was born and educated in Canada (B.Sc., Chemistry, McMaster, 1974; Ph.D., Chemical  Physics, UBC, 1978). His research focus is inner shell excitation spectroscopies and spectromicroscopies. A professor at McMaster since 1979, his group has built and operates gas phase inner shell spectrometers and reflection electron energy loss (EELS) systems for surface studies. In 1980 he started synchrotron experiments, initially  hard X-ray spectroscopy of materials at Cornell (USA), then soft X-ray spectroscopy of gases at LURE (France) and SRC (USA). In 1994 he began developing soft X-ray transmission microscopes (STXM) and photoemission microscopes (PEEM) at ALS (USA). In 2001 his group, in collaboration with researchers at NCSU and ALS, developed a novel, interferometry controlled STXM, which redefined state-of-the-art. He helped establish the Canadian Light Source (CLS, Saskatoon) and the CLS spectromicroscopy facility, currently equipped with 2 STXMs and a PEEM on a soft X-ray elliptically polarizing undulator beamline.  For the past 6 years he has helped develop applications of soft X-ray ptychography. His current research is focused on technique development and applications of  STXM and ptychography to automotive fuel cell materials, in situ electrochemistry, and magnetic bacteria. His teaching in Chemistry at McMaster has involved all aspects of physical chemistry, including spectroscopy, quantum mechanics, thermodynamics, statistical mechanics, as well as introductory chemistry.

  Jiri Matas: Computer Vision at (the age of) 55 - from a toothless theoretical baby to a start-up generating adult

Jiri Matas is a full professor at the Center for Machine Perception, Czech Technical University in Prague. He holds a PhD degree from the University of Surrey, UK (1995). He has published more than 200 papers in refereed journals and conferences. His publications have approximately 37000 citations registered in Google Scholar and 14500 in the Web of Science. His h- index is 69 (Google scholar) and 48 (Clarivate Analytics Web of Science) respectively. He received the best paper prize e.g. at the British Machine Vision Conferences in 2002 and 2005, at the Asian Conference on Computer Vision in 2007 and at Int. Conf. on Document analysis and Recognition in 2015. J. Matas has served in various roles at major international computer vision conferences (e.g. ICCV, CVPR, ICPR, NIPS, ECCV), co-chairing ECCV 2004, 2016 and CVPR 2007.

He has co-founded two companies, Eyedea Recognition (computer vision) and Locksley (combinatorial optimization).

Atmosphere & environment

  Martin Obst: Combining  Soft X-ray Microscopy with Electrochemistry to Study Redox-Sensitive Organic Materials

Martin Obst, Heisenberg-Professor for Experimental Biogeochemistry, started his study at the University of Bayreuth, Germany, He did his diploma in the interdisciplinary field of Geoecology in 1996 before he focused on geomicrobiology during his PhD at the Eawag/ETH Zurich. Soon he became interested in using synchrotron-based soft X-ray spectromicroscopy as a tool to study environmental processes at the sub micron scale. As a postdoc in Adam Hitchcock’s group at the Canadian Light Source (CLS) in Saskatoon, Canada, he was involved in the commissioning of the Scanning Transmission X-Ray Microscopy beamline and developed his own research program in environmental sciences before he returned to Germany. As a Emmy-Noether junior research group leader at the University of Tuebingen his research focused on the influence of environmental biofilms on the fate of heavy metals. In 2017 he became a Heisenberg-Professor for Experimental Biogeochemistry at the University of Bayreuth. His current research focusses on redox-transformations of carbon, iron or sulfur-species in the environment. Such processes are essential for various environmental topics including climate change, plant nutrition and environmental contaminations. Currently he is involved in the development of a combination of in-situ electrochemical manipulation/characterization of samples such as microbial organic polymers with (soft) X-ray absorption spectromicroscopy in the STXM.
