CEBA is intended to be an international meeting joining researchers in computational disciplines aiming at discussing and exploring different approaches to improve electrostatic calculations in the Molecular Biology field. Topics covered will be theoretical and numerical aspects of the solution of Poisson-Boltzmann equation as well as novel geometric approaches to the molecular surface creation and applications to the Nano-Biotechnology field. This meeting is co-organized with the Shape Modeling Group of the Institute of Applied Mathematics and Information Technology of the CNR and co-located with the Eurographics Symposium on Geometry Processing 2013, (3-5 July 2013 ), a premier venue for exchanging research results on a wide range of topics related to the creation of mathematical foundations and practical algorithms for the processing of complex geometric data sets and models. The scientific program will be based on different sessions, with plenary lectures, oral communications, and poster sessions. A special “hands on DelPhi” session is envisioned, allowing young researchers interested in how to exploit the functionalities of the DelPhi Poisson-Boltzmann solver to walk through worked examples and ask questions on specific issues.
