      I am a PhD Researcher at Tyndall National Institute. So I work with light, but it is a bit different because in my case light is travelling on chips, or circuits, these are called photonic circuits. For this to work I need to provide voltages, currents etc to modify the light signal by connecting these photonic circuits to our traditional electronic circuits (like the ones you see inside your phone if you open it up, I would definitely say try and open up your phone case and look at the different circuits there, just for fun)
      Warning- Don’t do that with a new phone, do it with an old one, and ask your parent’s help please
      So my work involves finding new ways apart from the ones already developed in the industry to connect these electrical circuits to photonic circuits, so that the light signals can carry the electrical data with faster speed ( because photons are faster than electrons). For example, how light travels faster than electricity.

      Hi,
      I am a PhD student at Tyndall National Insitute as well. In my work, I am mostly interested in knees. We are trying to help people recover faster after an injury and diagnose some conditions better ad cheaper. You might now, that our bodies produce different signals: electrical, mechanical and other signals. And the knee isn’t an exception: it makes noise when we move and muscles produce electricity. We can pick up those signals and see how the knee is doing. I’m working to develop a device that can help us do that. Some of such devices can even be made as smart clothes, such as pants :-).
