Dr. Usman Ghani Ph.D., MSc, BSc


Usman achieved a Bachelor of Science degree in Electrical (Computer) Engineering from the COMSATS Institute of information and technology in 2013. He graduated from the National University of Science and Technology (NUST) in 2016 with a master’s degree in computer engineering focused on brain signal processing.

He received a scholarship from Brain Research New Zealand (BRNZ) for his Ph.D. on cognitive workload evaluation using brain signals. In his Ph.D. thesis, he examined the effect of cognitive workload variation on EEG during a task. In his research, he seeks to develop a tool that can be used to assess cognitive workloads in patients who are receiving rehabilitation and chiropractic care.

His core expertise lies in data analysis, statistics, and EEG data collection/processing.
