The goal of the summer school is to present to students and researchers an integrated view of new trends and challenges in physical and mathematical aspects of biomechanics. Emphasis will be given on continuum theories and models for biological systems, essentially based on continuum mechanics, fluid or solid and their interaction. The school will be organized around 4 principal themes addressing both state-of-the-art theoretical (physics, theoretical mechanics, mathematics) aspects and applications. The main field of applications will be in the biology of the cell, plants and microbes, and in physiology.

Graduates in empirical sciences, maths, or engineering are welcome.
Physicists, Physical Chemists, Chemical Engineers, or Applied Mathematicians should be particularly suited
for the project, which just requires some basic knowledge of thermodynamics, and being not afraid of
programming a computer to perform numerical simulations. The latter is typically learnt by doing in the
first stages of a Ph.D, and in general anything can be learnt this way with the right attitude, which is part of the fun of doing research: always learning new things.

Candidates should preferrably hold a Master's degree, or have an official title enabling them to start a Ph.D. in their country of origin, with a minimum of 300 ECTS credits of higher education. If interested, do not refrain from contacting me just because of this.

The project consists in modelling the formation of the microstructure of a polymeric membrane,
when made by precipitating the polymer from a solution by means of a third chemical.
It is essentially a 3-component phase-separation problem. Such membranes are typically porous and
used as very fine filters, aimed at particles of different sizes. Therefore, one needs to control the
pore sizes (the microstructure) and hence the need for simulations. They can also be used to encapsulate
other chemicals... more in the direction of drug delivery. Experiments in both directions have and are
been done in house, and our goal is to compare with them. Alternative projects more in the direction of
biological membranes might also be possible, since both the supervisor and the host of this webpage have
some experience in that direction too. In any case, technically speaking the project will envolve solving
coupled reaction-diffusion partial differential equations, in principle by finite difference and simple numerical
methods.

Interested candidates please send an expression of interest and a CV to roger.folch@urv.cat
Please also indicate if you have an official master title.

The deadline for the application through the university will probably be end of April!

Modélisation des vecteurs de transport des médicaments

 La délivrance de médicaments (drug delivery) est un domaine de recherche interdisciplinaire qui consiste à acheminer un principe actif de manière localisée. Généralement, les principes actifs sont pièges dans un polymère (vecteur) qui peut exister sous forme de micelles, gels, complexes anion-cation, etc. La question principale est de trouver la structure optimale de ces vecteurs pour des applications concrètes.

 Dans ce contexte, les groupes joints "Systèmes Complexes" et "Polymères et Interfaces" à l’Université Rovira i Virgili Tarragona en Espagne, recrutent un candidat pour effectuer une thèse de 3 ans. Le candidat choisi intégrera la ligne de recherche de la modélisation théorique de systèmes de délivrance des médicaments. Il travaillera sur le développement de la Théorie de Champs Moyen d’une Chaîne Isolée dans le but d'identifier les mécanismes physiques de la cytotoxicité.

 Les vecteurs de délivrance assemblés dans une forme active sont généralement plus toxiques que chacun de ces composants dissociés. Les raisons de cette augmentation significative de la toxicité cellulaire causée par l’assemblage moléculaire restent inconnues. Bien que l’augmentation de la toxicité soit quelquefois attribuée à la capacité des vecteurs macromoléculaires de dissoudre la membrane lipidique dans leurs coeurs, cette hypothèse reste spéculative.

 Le candidat choisi utilisera la Théorie de Champs Moyen pour décrire les structures de complexes entre membranes et polymères afin de d'identifier les mécanismes de rupture des membranes. Le but de la thèse sera de déterminer les moyens de contrôler la cytotoxicité de vecteurs en jouant sur la structure des polymères. Les groupes "polymères et interfaces" possèdent une maitrise des outils de type de théorie de champs moyen, simulation numérique ainsi que des moyens informatiques (cluster) dont le candidat bénéficiera.

 Le candidat idéal sera un étudiant de master en physique ayant une bonne connaissance de physique statistique et des méthodes numériques, et surtout motivé pour travailler dans le domaine de drug delivery et la biophysique.

Modelling of drug delivery vectors

Drug delivery is a domain of interdisciplinary research aimed in local delivery of active principle.


Joint groups “Complex Systems” and “Polymers and Interfaces” of the ETSEQ at the University Rovira i Virgili of Tarragona Spain, are seeking a candidate for a 3 year PhD program. The selected candidate will integrate the research line on theoretical modelling of Drug Delivery systems to work on the development of the Single Chain Mean Field theory to discover the physical mechanisms of the cytotoxicity.

Often the polymeric drug carriers in the assembled state are more toxic for cells than when in a dissociated state. The reasons of this significant increase of toxicity for the cell when assembled as well as the ways to reduce it are still unknown. Although the increased toxicity is sometimes attributed to the ability of the drug carriers to dissolve membrane lipids in the carrier cores, this remains as a speculative idea. During the contact with cell membranes the drug carriers may suck phospholipids and other constituents of cells into the cores, thus irreversibly damaging them. Hydrophobic polymers may precipitate onto and aggregate with the cell membrane forming pores that could be fatal for the cell. 

The selected candidate will use the Self-Consistent Mean Field theory to describe the structures of membrane – polymer complexes in order to discover the mechanisms of the membrane disruption. The research will aim to find the way to control the cytotoxicity by adjusting the structure of the polymers used for concrete practical applications. The group has almost exclusive personal and computational fascilities: at present we have a cluster of 21 nodes with four AMD Opteron processors and 4Gb and 16Gb of RAM.

Within the framework of this PhD there is a possibility of a shared PhD with Professor Emmanuel Trizac, the Laboratoire de Physique Theorique et Modeles Statistiques, Universite de Paris-Sud, France. 

We seek a candidate with Master degree in Statistical physics with good knowledge of Theoretical physics and numerical methods and motivated to work in the field of soft matter physics, statistical physics of polymers and biophysics.

For three decades this biennial meeting has brought prominent senior and younger scientists in all aspects of biology, medicine, physico-chemical and pharmaceutical fields to meet the common interests and goals of better drug therapy using novel strategies of drug delivery and drug carriers. The 2008 meeting will focus on several areas of drug delivery including protein and oligonucleotide/gene delivery, polymers and lipid particles, nano-materials, antibody drug-conjugates and cellular carriers, directed to various targets at multiple levels, as well as multimodal molecular imaging applied to monitoring delivery and therapeutic efficacy. This meeting will also include the approaches of chemical biology and nanotechnology to target and achieve enhanced delivery and therapeutic outcomes.
