Welcome!

Welcome to my website! I am Sebastiaan Breedveld, assistant professor at the unit Medical Physics, department of Radiation Oncology Erasmus MC Cancer Institute (Erasmus University Medical Center) Rotterdam, The Netherlands.

It is my ambition to greatly improve radiation therapy treatment, providing the highest quality treatment possible, for each individual patient.

Radiotherapy is one of the main treatments for cancer, and a multi-disciplinary field of research, mostly involving medicine, physics and mathematics. My focus lies in improvements from the field of mathematics, where the subfields operations research, decision-analysis, optimization, numerical mathematics and mathematical physics play the most prominent role.

I have been working on inventing new treatment planning algorithms, resulting to the Erasmus-iCycle algorithm. Through the efforts of many people, this was introduced clinically in 2010. The number of patients treated is still expanding, with a total close to 500 in 2013, more than 10% of the radiotherapy treatments at the ErasmusMC - Cancer Institute!

On this website you will find my academic CV, background information on radiation therapy, the mathematics involved, illustrated by many figures, movies, and you can even perform Pareto-navigation online!

Feel free to use the information and content provided for presentations, just make sure you name the Erasmus MC - Cancer Institute.


Under Construction

This site will soon contain more information on mathematics applied to the field of radiation therapy physics. It is currently under construction, so not all sections are fully available.
