Science
As
a researcher I'm interested in
the way the human brain and the human body create functional movements.
Presently I'm working at The Institute
of Human Movement Sciences of
the University of Groningen.
Applied
projects deal with
speedskating, the control of leg prostheses and cortical
representations of the dynamics of the human body.
In
Groningen in the Netherlands we
use the CAREN
system, a virtual reality environment for the study of movement control.
An athlete in the virtual reality
environment
Frames from an animation,
illustrating how humans start walking, using extra propulsion from hip
muscles
Simulation of Speedskater Straight and
Curve
Amputee
tested in Caren Lab
I
wrote the simulations of human movements on an Apple Macintosh
computers in an application called
HbmTbx (Human body model toolbox).
The
simulations are in 3D and can
handle up to 19 rigid bodies and 160 muscles. The dynamics are
calculated using automatically generated Lagrange equations of motion.
There
is a close connection between
the measurements in 3D of human body motion and the simulations. The
dynamical calculations can be inverse or forward, depending on the
purpose.
Awards
1. In september 1984 I received the C.J. Kok award from the associated
faculties of sciences in the Netherlands for originality of my thesis
entitled "Vision and Jaw Mechanism during Growth of the Cichlid Fish
Haplochromis elegans".
2. In 1986 received an award from the Dutch Association of Histologists
for the best poster entitled "Reconstruction: a joining of
forces" together with Mrs. IJkema-Paassen.
3. In 1991 I received an award in a dutch scientific tv program
for the
software I wrote for optimal placement of bone plates in a broken human
jaws.
4. In 1998 I received an award for a poster entitled “A new
leg to stand on” on the Sixth European Congress on Research in
Rehabilitation in Berlin together with A. de Vos and W.J. van der
Eerden (AMC).
