About Me
I am a Postdoctoral Researcher working on {Machine | Deep | Federated | Privacy-Preserving} Learning at Information Processing and Communications Lab at Imperial College London working on reliable and privacy-preserving federated learning on the edge devices, with Prof. Deniz Gunduz. I have completed my PhD in Computer Science at Queen Mary University of London as a member of Centre for Intelligent Sensing under the supervision of Prof. Andrea Cavallaro (formerly, Dr. Hamed Haddadi) and Dr. Richard G. Clegg, supported by Life Sciences Institute. My Ph.D. research was focused on privacy-preserving machine learning mechanisms for behavioural data analysis, particularly for motion sensor data generated by the mobile and wearable devices. I have been a Ph.D. intern at Brave Software where I worked on privacy-preserving content personalization, working with Dr. Dimitrios Athanasakis and Dr. Benjamin Livshits. I have also been a visiting PhD student at Imperial College London, as a member of DataboxProject, working with Dr. Hamed Haddadi. Please download my CV for more information.
