Ñݽ²Õß¼ò½é£ºProf. Xiaoguang Liu received his Bachelor¡¯s degree from Zhejiang University in 2004 and PhD degree from Purdue University, USA in 2010. He joined the Department of Electrical and Computer Engineering, University of California, Davis in Nov. 2011 as an assistant professor and was promoted to an associate professor in Jul. 2017. At UC Davis, his research group is investigating various aspects of cutting-edge high-frequency circuit and system design and implementation concepts. Besides typical duties inside the University and professional societies, Dr. Liu has consulted for a number of companies and national labs on topics related to high-frequency circuits, antennas, and systems.

½²×ùÌáÒª£ºAtrial fibrillation (AFib) currently affects the well-being of 7.7 million patients in the USA and more than 33.5 million worldwide. AFib occurs if rapid, disorganized electrical signals cause the heart's two upper chambers¡ªcalled the atria to fibrillate. AFib can lead to stroke, heart failure, uncontrolled fainting and even death which results in a poor quality of life. A significant medical need for AFib patients can be met with the development of a take-home and long-term wearable arrhythmia monitoring system for people who are suspected of having paroxysmal (non-continuous, irregular) episodes of AFib as well as numerous other heart arrhythmias.  In fact, the accurate measurement of the percent of time or percent burden that a patient experiences these types of arrhythmogenic events can guide the course of therapy.
