Javier Vijande is a professor at the Molecular, Nuclear, and Atomic Physics department of the University of Valencia, Spain. He holds a PhD in physics from the University of Salamanca where he was an Assistant Professor before moving to Valencia to occupy a researcher position in the Theoretical Physics department until joining the Molecular, Nuclear, and Atomic Physics department in 2009. His research focus has always been linked to computation-intensive calculation techniques. In the beginning of his scientific career he worked in developing numerical methods to approach the few- and many-body problems in hadronic physics. Nowadays, his main research interests are Monte Carlo simulations in the field of medical physics and its clinical applications. Professor Vijande serve as a member of the BRAchytherapy PHYsics Quality Assurance System (BRAPHYQS) working group of GEC-ESTRO and the American Association of Physicist in Medicine (AAPM) Brachytherapy Subcommittee, Brachytherapy Dosimetry working group, Brachytherapy Source Registry working group, and as Chair of the Working Group on Model-Based Dose Calculation Algorithms in Brachytherapy.
