Interest in engineering

Why did you get into engineering?

I got into engineering because I enjoy combining theory with practise to invent things that work.

What are your research goals?

My research goal is to shape the architecture of the Internet to support growing traffic volumes while providing high service quality in a cost-effective way, so that applications ranging from video to healthcare and education can function effectively.

What do people not understand about you do?

People often take things that work for granted, and do not appreciate that it takes a lot of research to make the right design choices in building systems (such as the Internet) that need to scale well into the future.

Advice for prospective Telecommunications engineers

The Internet is still in its early days, and there is tremendously exciting work to be done in developing the technologies that will sustain and enrich this digital revolution.
