Description :
The Laboratory of Fluid Mechanics and Rheology at the University of
Patras has three Marie-Curie Fellowship openings at the Doctoral level, (“Early-Stage Researcher” ESR), under the supervision of Profs Yannis Dimakopoulos and John Tsamopoulos, in the following area :


The proposed research is focused on predicting and controlling
deformation and flow of a group of complex materials abundant in nature
and industry, called Yield-Stress (YS) or viscoplastic (VP)
materials. These start to flow when a sufficient stress is applied to
them but behave as solids otherwise.
Predicting the behaviour of YS materials is particularly challenging for
at least three reasons :
(a) It is challenging to determine material properties accurately.
(b) Inappropriate constitutive models have often been used, i.e.,
generalized Newtonian fluid models, whereas recent experiments have
shown that they also exhibit elastic and thixotropic properties.
(c) It is challenging to compute complex flows because of their
transient nature.
In response to the challenge of predicting flows of YS materials, it is
imperative to establish a coherent and efficient approach to predict such flows by (a) developing more accurate and general YS constitutive models, (b) developing advanced numerical methods for computing complex YS flows In this way, it will become possible to bridge the gap between science and modelling developed in academia (fluid mechanics, rheology, and computational methods) and process engineering (food, chemical, pharmaceutical, oil exploration, construction, etc.).
The overall goal of our research effort is to develop such models and
test them in homogeneous and specific complex and practical flows.
The position is funded in part by a Marie-Curie ITN project for a period
of four years. Candidates must have BS or MS degrees. in Chemical or Mechanical Engineering, Physics, Materials Science, Appl. Mathematics, or a related field.
Review of candidate applications will begin December 18, 2020, and will
continue until the positions are filled. Prospective candidates should
prepare a single PDF document including (1) a cover letter detailing
motivation, research experience, and research interests, (2) curriculum
vitae, (3) names and email addresses of three references. These can be
sent by email to Prof. John Tsamopoulos at
In the selection process, candidates will be assessed upon the following
skills :
o Ability to analyze and model complex physical problems
o Programming skills (good knowledge of at least a language among
Fortran 2015, C++, Python, Matlab)
o Background in soft matter, multiphase flows, and transport phenomena
o Enthusiasm about working in a multidisciplinary, collaborative
o Excellent interpersonal and communication skills (written and spoken
o Ability to work and collaborate in a diverse environment.
The candidates
o Can be of any nationality, and there is no age limit.
o At the time of recruitment, they must be in the first four years of
their research careers and not yet have been awarded a doctoral degree.
The four years start to count from the date when a researcher obtained
the degree which would formally entitle him/her to embark on a doctorate.
o Researchers are required to undertake transnational mobility (i.e.,
move from one country to another) when taking up their appointment. One
general rule applies to the appointment of researchers : At the time of
recruitment by the host beneficiary, researchers must not have resided
or carried out their main activity (work, studies, etc.) in the country of their host beneficiary for more than 12 months in the three years immediately prior to the reference date. Note that the mobility rule applies to the beneficiary where the researcher is recruited and not to beneficiaries to which the researcher is sent or seconded.
o For all recruitment, the eligibility and mobility of the researcher
will be determined at the time of their (first) recruitment in the project.
