Cornelis
A. Grimbergen (Kees) was born in Leiden, the Netherlands, in 1947. After
receiving his Ir. degree in Electrical Engineering at the Delft
University of Technology he was active in research in solid-state physics,
semiconductor technology, resulting in a Ph.D. degree in 1977 from the
State University of Groningen. From 1977 he has been with the Laboratory
of Medical Physics of the Faculty of Medicine of the University of
Amsterdam working as an assistant-professor. From 1991 he is a part-time
professor at the Measurement & Control Department of the Faculty of
Mechanics of the Delft University of Technology. From 1995 he is also
professor in Medical Technology at the Academic Medical Center of the
University of Amsterdam (AMC).
Since
1996 he is heading the MTO, the medical-technological development
department of the AMC, a development workshop with about twenty
mechanical, ten electronical and two glass engineers. He is involved in committees
determining the strategy of acquisition of instrumentation for the AMC and
organizes annually a symposium on trends in medical technology.
His
interests and research projects are in the fields of medical
instrumentation, biomedical signal and image processing, and
minimally-invasive techniques.

Dr.
E.
VanBavel (Associate Professor of Medical Physics)
e-mail:
e.vanbavel@amc.uva.nl
Ed van Bavel obtained his Masters Degree at the Leiden University in 1985
and received his Ph.D. Degree in 1989 in Amsterdam. Since then he has been
working on micro vascular biomechanics and the control of microvascular
tone and structure. Emphasis in this work is on the behavior of isolated
arterioles in acute settings and in culture. Functional studies on these
vessels are combined with calcium imaging and vascular biology. Remodeling
is studied in vitro in cultured arterioles under pressure and flow.
This work is extended with mathematical modeling
and simulation techniques.

Dr. ir. G.J. Streekstra
e-mail:
g.j.streekstra@amc.uva.nl
Geert
Streekstra was born in Kampen in 1961.
He received his master degree in Technical Physics at the Twente
University in Enschede in 1988. In
the same year he started his Ph.D. research at the departments of Medical
Physics and Haematology of the Utrecht University.
In Utrecht he designed and implemented a rheoscope for the
measurement of deformation and orientation of red blood cells in flow and
developed a theoretical description of the light scattering by red blood
cells in an Ektacytometer. In
1994 he received is Ph.D. degree and started as Post-doc at the University
of Southern California California to investigate the utilization of the
light scattering theory for measurement of red cell deformability in
patients with Sickle Cell Disease.
In
1995 he started as a researcher at the dept. of Experimental Cardiology of
the Utrecht University where he worked on the development of an automated
grafting method for bypass surgery. From
1996-2000 he was Post Doc in the depts. of Intelligent Sensory Information
Systems and Molecular Cytology at the University of Amsterdam.
In Amsterdam the research activities were devoted to image analysis
in 3D confocal microscope images in particular detection of threadlike
structures and analysis of time sequences.
Since
2000 Geert Streekstra has been assistant professor at the department of
Medical Physics. His current
research interests are the analysis of 3D medical images from several
imaging modalities and development of haemorheological instrumentation.

Dr.
Henk Venema
e-mail:
h.w.venema@amc.uva.nl
Henk W. Venema received the MS and PhD degree in Experimental Physics
from the University of Amsterdam, Netherlands, in 1969 and 1982,
respectively. He joined the Laboratory for Medical Physics, and in 1973
also the Radiology Department, both of the University of Amsterdam. His
PhD research was on the analysis of the spatial distribution of fiber
types in muscle cross sections using Markov Random Field models.
At present he works both at the Medical Physics Department and the
Radiology department of the AMC. His current research interests are
image processing and pattern recognition, and the physical and
mathematical aspects of image formation with x-rays (both conventional
and CT) and radiological protection.

Dr. ir. Maria Siebes
e-mail:
m.siebes@amc.uva.nl
Maria Siebes received her engineering degree (Diplom-Ing.) in Technical
Health Sciences from the University of Applied Sciences in Giessen,
Germany, in 1981 and worked at the Max-Planck-Institute for
Physiological and Clinical Research in Bad Nauheim, Germany, where she
investigated the pressure-flow characteristics of arterial stenoses.
With a Fulbright Scholarship she enrolled in 1983 at the University of
Southern California, Los Angeles. During her studies, she was awarded
two ZONTA Amelia Earhart Fellowships and worked on quantitative coronary
angiogram analysis as a member of the Biomedical Image Processing Group
at the Jet Propulsion Laboratory/CalTech in Pasadena. She received her
M.S. (1984) and Ph.D. (1989) degree in Biomedical Engineering. Her PhD
thesis is entitled “Modeling and Simulation of a Compliant Coronary
Stenosis during the Cardiac Cycle”.
In 1989, she became Assistant Professor in the Dept. of Biomedical
Engineering of the University of Iowa in Iowa City, IA, where she was
active in teaching (Outstanding Teacher Award in 1992) and
interdisciplinary research, supported by grants from the Whitaker
Foundation, National Institutes of Health, and National Science
Foundation. In 1996, she spent her sabbatical as Visiting Scientist at
the Cardiovascular Research Institute of the University of Amsterdam and
transferred in 1997 to the Dept. of Cardiology at the Academic Medical
Center. Since 2002 she holds a tenured faculty position in the Dept. of
Medical Physics at University of Amsterdam.
Dr. Siebes is Associate Editor of Medical and Biological Engineering &
Computing and a member of several national and international
professional societies in engineering and cardiology. She currently
serves on the Council of the European Alliance for Medical and
Biological Engineering and Science (EAMBES) and chairs the ‘Women in MBE’
Committee of the International Federation of Medical and Biological
Engineering (IFMBE).
Her research
interests center on the coronary circulation in health and disease, with
an emphasis on the assessment of the coronary microcirculation and
functional stenosis severity from physiological measurements in man. Her
work combines biofluid mechanics, medical imaging, physiology, and
modeling of the coronary circulation.
