Texas Tech University is ranked as R1 research university. My research is about applying Machine Learning (ML) techniques in Cybersecurity and using ML to improve wireless communication performance in IoT applications. I have a PhD open position for 5 years starting from 2022 Fall. Students are allowed to graduate within four years if requirements are met (don't worry, we work as a team). Anyone who is interested in my research is welcome to contact me by email at jingjing.yao@ttu.edu. Please attach your CV and transcripts if you do.
