My research focuses on the numerical optimization and improvement of the minimally invasive techniques that employ electromagnetic energy for surgical treatments in oncology and other medical applications. The areas of my interest are RF ablation for tumor ablation and Pulsed Radiofrequency (PRF) for non-thermal pain treatment and electroporation, known as electropermeabilization of cell membranes with high voltage electric pulses for unresectable tumors management. In my project I combine the development of numerical models with experimental and clinical studies and study the thermal and electrical phenomena in the biological tissue subjected to one of the previous techniques. Using these tools I cover in my research the specific issues such as:
1) internally cooled wet electrode as a way to increase the coagulation zone size in the treatment of hepatic tumors,
2) optimization of pulsed radiofrequency protocol for pain relief in order to reduce the risk of thermal damage while potentiating its electrical effect, and
3) computer models of thermal damage to better define the thresholds for transient and permanent thermal damage as dependent on temperature and exposure time.
