At age 17, Ivan Zelich co-developed a groundbreaking mathematical theorem that works faster than a computer and has applications in better understanding geometric structures. The Liang-Zelich Theorem paved the possibility for anyone to deal with the complexity of isopivotal cubics having only high-school level knowledge of mathematics. A paper on the theorem was published in the peer-reviewed, International Journal of Geometry, making Zelich and his collaborator Xuming Liang, the youngest contributors ever to the journal. Aside from his passion for numbers, Ivan is a swimming state champion, speaks six languages, and has represented Queensland in chess. He is currently undertaking his fast-tracked, undergraduate degree at University of Queensland.
