My primary interest is to fully utilize the latest technology in radiation therapy available at UC Irvine to deliver the most efficient and effective treatment to a patient. For this purpose, I have worked in the implementation and dosimetric measurements of VMAT (volumetric-modulated arc therapy) for SRS/SBRT treatments, have performed fetal dose measurements outside a VMAT treatment field using an anthropomorphic phantom to determine potential risks to a patient, and have investigated the effects on cognition after a high dose (10Gy) irradiation of the whole brain and single hippocampus of athymic nude rats using a high-precision VMAT technique.
In addition to this work, I have given numerous presentations and webinars on the use of a VMAT technique highlighting my experience working with it and its efficacy.
Finally, I teach physics to radiation oncology residents (MDs), which is always a rewarding and stimulating experience since this group brings a clinical perspective which often differs from the analytical approach that characterizes the physics field. This is the synergy that I embrace and pursue.
