Hello, I work as a research associate at the David R. Cheriton School of Computer Science, University of Waterloo. My current research is about computer networks and blockchain. Previously, I earned a Master of Mathematics degree and a Bachelor of Computer Science degree from the same institution. My master’s thesis focuses on mitigating signalling storms in 5G cellular networks.

Throughout my studies, I have explored advanced fields such as artificial intelligence, blockchain, 5G cellular networks, and space networks. I have realized that many modern technological advancements arise from solving important problems with simple and effective ideas. Thus, this is the first principle I follow while conducting my research. Unfortunately, the problems I solve are not significant enough to be game changers. Perhaps this is why we often say that finding a good problem to solve is 50% of success. Another research principle I adhere to is practicality. I believe an idea in computer science is only useful when it shows potential to address real-world problems. In my related research fields, this mainly involves scalability and use case scenarios.

Over the years, I have found that I enjoy performing data analytics, forecasting, and reasoning to discover phenomena and trends in the real world. However, I am even more passionate about designing scalable communication systems and protocols. The trade-off between security, efficiency, and reliability is fascinating.
