Hello and welcome to my page. I have completed PhD in the Cognitive Reconfigurable Embedded Systems (CORES) Lab at UCLA in June 2018. I am currently working at Samsung Semiconductor, Inc on developing advanced algorithms for 5G modem. During my graduate study, I worked on the following topics:

• Machine learning for 5G/wireless communications,
• Channel selection and power allocation for underlay CR using Markovian Multi-Armed Bandit approach,
• Interference management, power allocation, and user selection in underlay cognitive radio network with Massive MIMO,
• Transmitter localization in the presence of interference,
• Blind modulation classification of unknown signals.

Education

• Ph.D. Electrical and Computer Engineering, University of California, Los Angeles, 2018
• M.S. Electrical Engineering, University of California, Los Angeles, 2013
• B.Tech. Electronics and Telecommunication, University of Pune, India, 2010
