Dr Yogachandran Rahulamathavan

Senior Lecturer, Institute for Digital Technologies


Dr Yogachandran has a PhD in Signal and Information Processing and has worked at Loughborough University as a postdoctoral research associate.

Yogachandran received his PhD degree in Signal and Information Processing from Loughborough University in 2011 and then worked as a postdoctoral research associate for six months on encrypted signal processing technique for privacy-preserving multimedia Big data processing. Subsequently he joined City University London as a research fellow in information security within the School of Mathematics, Computer Science and Engineering in 2012.

Yogachandran's research interests are on developing novel algorithms for Internet-of-Things, especially on advancing privacy-preserving data processing methods for cyber-physical systems such as cloud and smart networks, application of which spans mhealth, smart home, smart grid and connected cars. This involves processing big multimedia data in cloud system without violating users’ privacy. For this he redesigned the state-of-the-art machine learning techniques such as support vector machine, Gaussian mixture models, and Linear Discriminant analysis using cryptographic primitives to work on encrypted domain.
