A bit about me

I have been interested in science since I was a teenager, and I received several awards in the Aer Lingus Young Scientists Exhibition (a popular national science competition for schoolchildren in Ireland) for my research into chloroplast migration in the Caulerpa floridana marine algae. Specifically, I received the Irish Professors of Botany Award in 1994 & 1995; the Institute of Biology Ireland Award in 1995 & 1996; and 1st prize in the Biological and Ecological Sciences Senior Individual category in 1995 & 1996.

I also was interested in mathematics (and competed in the Irish Mathematical Olympiad), and an avid computer programmer – in 1996, I came 4th in the Under-18 category of the IBM DCU All Ireland Schools Programming Competition, and I was awarded the Prof. Rykov Trophy for computer programming in 1994.

So, naturally, I studied science in college. I specialised in Chemistry, and I received the Bristol Myers Squibb Award for the best final year project (in the Measurement/Calculation section). But, at this stage I had become impressed by the great “polymaths” and realised that I wanted to be a multi-disciplinary scientist. So, when I was offered the chance to do a Ph.D. which combined chemistry, biophysics, polymer physics and computer modelling, I took it. My thesis was “Conformations of branched polymers”, for which I was awarded the BOC Gases Award for best Ph.D. research.

After my Ph.D., I began working with my father, Michael, on a number of topics. We have been researching and developing:

  • New technologies and techniques for fish-farming, aquaponics and waste-water treatment
  • Low cost heat-exchangers
  • New energy efficient building materials and techniques

We have investigated the life cycles and spawning conditions for hundreds of species of fish, invertebrates and algae.

Along the way, I built several houses and buildings with Michael, and learnt a lot about different construction techniques.

We began actively researching climate change in early 2009. We initially launched this blog in 2014, and re-launched it in 2021.

Finally, I love music, and I am interested in history, archaeology and anthropology.
