Xinyuan Sophia Cui


I graduated from Washington University in St. Louis in May 2012. During my time in Dr. Efimov’s lab, I built and tested pacemaker for mice. Successfully halved the size of original Medtronic design and composed detailed technical user manual for the construction, utilization and alteration of the device. In addition, I assisted in creating a MATLAB graphical user interface (GUI) to translate raw optical mapping data into meaningful graphic representations. Dr. Efimov was also my mentor on my senior design project on the topic of implantable flexible and stretchable devices for cardiac therapy. My design group came up with a 3D model for a defibrillator composed of finger-like extensions that span from the apex to the base of the heart. The extensions contain sensing and stimulating electrodes to detect arrhythmias and locally defibrillate active foci, respectively. Currently, I am pursuing a PhD degree in biomedical engineering at the University of Virginia. My research focus is on cardiac imaging.
