Being an active researcher has helped me keep ahead of developments and understand different subjects. I have the opportunities to introduce new modules, which are influenced by my research in the areas of signal processing and its applications. At the MSc level, I present lectures which incorporate some of my results in research into the advanced modules. This enables students to be well-informed and up-to-date of new developments and future trends.
