Summary
I am a Research Fellow at the Wearable Technologies Lab in Circuits and Systems Research Group. My primary research interests lie in biomedical signal processing, algorithms, and mixed-signal circuit design of wearable systems, low power digital circuits for medical applications and embedded systems design. I am interested in creating novel devices to aid the monitoring, diagnosis, and management of epilepsy, sleep and chronic respiratory disorders. I received my PhD at Imperial College in 2015, MSc in Analogue and Digital Integrated Circuit Design at Imperial College in 2009, and BEng in Electronic Engineering at National University of Sciences and Technology (Pakistan) in 2008.
