The Institute for Biomechanics at ETH Zurich is seeking to appoint a highly
motivated post-doctoral fellow to perform research on:

COMPUTATIONAL MECHANICS OF BONE-IMPLANT FAILURE

Together with an aging population the problem of osteoporotic fractures
increases tremendously; despite all pharmaceutical efforts roughly 1.5
million people suffer from an osteoporosis-related fracture each year.
Treatment can be complicated, and often leads to poor functional outcomes.
One of the reasons why implants (screws, nails, etc.) perform worse in
osteoporotic bone is the limited support due to reduced bone mass; however,
the precise mechanisms underlying implant anchorage and implant failure are
still unknown.

To better understand the basics of implant fixation we have started several
research projects. Currently, our research is focused on experimental
assessment of implant stability and on modeling peri-implant bone
architecture and its quality. We wish to expand our efforts with
computational analyses of implant stability. We aim to create finite element
models of implant-bone interaction that take the full trabecular bone
architecture as well as realistic implant geometries into account. Recent
advances in microarchitectural bone imaging coupled with multi-level
microstructural finite element analyses offer powerful tools to create and
solve such detailed large-scale models on parallel computer systems. We
expect that this will lead to a deeper understanding of the relative
importance of bone failure and failure of the bone-implant interface. A
specific target of our modeling efforts is to assess implant stability in
differing degrees of osteoporotic bone.

The advertised position will start as soon as possible and will initially be
granted for two years, with a possibility to extend with another two years.
During this period the candidate will be given the opportunity to form
his/her own research team. Salaries are highly competitive and in accordance
with ETH regulations.

The applicant should have a recent PhD in Biomedical Engineering, Mechanical
Engineering, Physics, or other relevant discipline. A strong background in
finite element analyses is mandatory; experience in non-linear and
microstructural analyses, as well as programming skills on parallel computer
systems are highly advantageous. Good skills in both spoken and written
English are expected; knowledge of German is beneficial. Candidates should
be able to work both independently and as a member of a team.
