My work brings innovation in building secure and reliable network systems. My research identifies fundamental open questions and explores them from various angles. It contributes to better understanding of the state-of-the-art network systems by challenging their operational efficacy, and identifying unexplored aspects at their heterogeneity. It provides simple and innovative solutions from system designs to their operations through testing.

Taqi is a 5th year PhD student at Computer Science department of UCLA under Prof. Songwu Lu. Before joining UCLA, he was a Research Associate Engineer in the LTE Protocol Division at the MC Gasan R&D Campus, LG Electronics, Seoul, South Korea. Prior, he received his BS in Information Technology from NUST - Pakistan, and MS in Information and Communication Engineering from Ajou University - South Korea.
