Welcome!
This website provides details about my educational and professional background, my research interests, my teaching responsibilities and my administrative duties, both internal and external. Please either scroll down or use the menu to navigate my website.
Research
My research interests lie in the general area of communication theory and include the modelling, analysis, performance evaluation and design of communication systems. My focus has been on coding schemes for multiple-antenna systems and cooperative networks. Recently, my focus shifted to random linear coding over finite fields, as the means to reduce delay and improve throughput.
Teaching
As part of my duties in 2019-2020, I am involved in the teaching of the following modules:
- SCC.400: Research Methods (MSci/MSc Computer Science)
- SCC.460: Data Science Fundamentals (MSc Data Science)
Service
As part of my departmental duties in 2019-2020, I fulfill the following roles:
- Year 2 Undergraduate Tutor
