Moreover, those detachment models are implemented into the OpenFOAM^® and are used for Euler/Lagrange calculations of an inhaler device and allow an optimization with regard to pressure drop and efficiency of drug powder delivery. Finally, he is looking for collaboration with other SimInhale members who can provide measured particle contact properties (e.g. adhesion force, surface energy, friction coefficient) for different surface treatment methods of carrier particles.

Keywords of expertise: 1. Particle engineering, 2. DPI Device development, 3. In vitro assessment of respirability, 4. Spray drying technique for dry particle manufacturing

Golden Paragraph: Paolo Colombo primary research activity in inhalation is the design and development of novel inhalation products with a special focus on DPI. The primary goal is the search of a safe and convenient administration of large doses of drug in particular antiinfectives, to treat lung microbial and viral dependent diseases. In this regard the recent pubblications on cystic fibrosis Pseudomonas infection treatment by aminoglycosides drive to an approval for orphan designation of a powder of amikacin or tobramycin. The product is administered with a new device for powder inhalation capable to accept a dose of powder larger that 100 mg. We found a novel system and technique capable to regulate the powder emission in order not to suffucate the patient during inhalation since the large dose is emitted in small portions. This allows the complete deposition of the drug in the lung area defined by the aerodynamic size distribution of the aerosol particles.

In 2004 he obtained a ‘Ramon y Cajal’ Spanish government contract to study indoor ventilation in buildings. Two years later he joined the newly created Barcelona Supercomputing Center-Centro Nacional de Supercomputación (BSC-CNS) to start the CFD research line in the Department of Computer Applications in Science and Engineering. Since then he has been working in basic research (variational multiscale), applied research (ventilation, biomechanics), and on the parallelization, optimization and tuning of Alya simulation codes for very large scale simulations.

PhD Candidate, Computational Sciences Laboratory (UCY-CompSci), Department of Mechanical and Manufacturing Engineering, University of Cyprus

Keywords of expertise: 1. Computational Fluid Dynamics, 2. Incompressible flows, 3. Biomedical fluid flows (lungs), 4. Numerical simulations

Golden Paragraph: Pantelis Koullapis is a PhD candidate at the Computational Sciences Laboratory (UCY-CompSci) of the University of Cyprus. The primary research activity of Pantelis in SimInhale is the use of high fidelity computer simulations for the prediction of drug deposition in the airways, in particular the prediction of regional deposition for various combinations of inhaler devices, patient groups (based on age or health status) and formulations. In this regard, he is interested in the development of In Silico In Vivo Correlations (ISIVCV) for deposition. In collaboration with other SimInhale members, Pantelis is also pursuing the development of hybrid models coupling the upper airways to the alveolar region, e.g. using LES methods for the upper airways with reduced models for the deeper airways.
