Bibliography

I am with Qualcomm Inc. New Jersey Research Center since 2020, conducting wireless research on physical and MAC layer for 5G/6G and beyond (including 3GPP RAN1 standardization). I obtained my B.Sc, M.Sc (with Honors), PhD (Summa Cum Laude) in Electrical and Communication Engineering at University of Stuttgart in 2012, 2014 and 2019, respectively. My research focus is novel multi-carrier waveform, massive MIMO, iterative detection and decoding, and non-orthogonal multiple access techniques.

I am passionate about doing research for communication systems and gathered research and development experience in the physical layer of wireless and optical communications systems, particularly, error control codes, waveform design, multi-user detection and digital signal processing.
