I have a bachelor’s in Engineering Physics and a master's degree in Biomedical Engineering. It is my passion to investigate how physics can be used to improve the medical world. Currently I am conducting research to implement photoacoustic imaging for gathering real-time information of the state of liver tissue during the therapeutic tumor destruction process called radiofrequency ablation of the liver. This information could give surgeons real-time information about the success of procedure, giving them more ability to steer the procedure for optimal patient outcome. Also I am conducting research for ultrasound and photoacoustic imaging to guide catheters during some neurosurgical maneuvers.
