Postdoc Fellow, Department of Computer Science, University of California, Los Angeles (UCLA)
I am a postdoctoral researcher in department of Computer Science at UCLA. My research is on wireless networks spanning from high data rate mmWave communication to low power sensing devices. In my research I get benefit from fundamentals concepts in wireless networks along with most recent techniques in different areas including advanced signal processing, efficient RF and antenna design and machine learning. My passion is to develop innovative wireless networks with optimized power consumption and enhanced network throughput.
