Niall has over 5 years experience as a hydraulic modeller.

As a graduate from Ulster University with a degree in Environmental Science, my career has been dedicated to advancing solutions in wastewater and Integrated Environmental modelling. With a diverse background spanning esteemed consultancies such as Atkins, RPS, McAdam, and WSP, as well as secondments to NI Water, I have played a pivotal role in shaping sustainable water management practices. In these roles, I had the opportunity to work on a myriad of projects, ranging from wastewater treatment plant design to river basin modelling and flood risk assessment. Through collaborative teamwork and innovative approaches, I strived to deliver solutions that balance environmental conservation with societal needs.

In my free time, I am a coach for kids' Brazilian Jiu-Jitsu (BJJ), I find immense joy in guiding young minds to discover their potential, teaching not just martial arts skills but also valuable lessons in discipline, teamwork, and resilience.
