Timothy McGrath, a sixth-year student from Community College Killorglin, Co. Kerry was named the overall winner of SciFest 2019 for his research and development of a biofilter to combat oceanic and freshwater dead zones. As a result of winning SciFest 2019 Timothy was due to represent Ireland at Regeneron ISEF 2020 in Anaheim, California in May. Due to COVID-19 the event in Anaheim had to be cancelled. The normal fair was replaced with a virtual Regeneron ISEF 2020. This took place 18 - 22 May and included not only details of all the 2020 finalists' projects but also speakers of the highest caliber, focusing on topics ranging from COVID-19, to entrepreneurship and to being a woman in STEM.

Through research Timothy realised that eutrophication, an enrichment of water by nutrient salts, which causes structural changes to the ecosystem, turns huge areas of the ocean into dead zones and affects many countries as a result. Dead zones are low-oxygen areas in the world's oceans and large lakes, caused by excessive nutrient pollution from human activities. Timothy created a technically viable solution and built a structure that stored a halophyte ecosystem that would reduce nutrient pollution, decreasing algal blooms and deoxygenation of ocean water and freshwater. Timothy was one of 77 students who qualified to exhibit 41 STEM projects at the SciFest 2019 National Final.
