Kong Khai Jien is the initiator of CUO. He is a multidisciplinary biologist currently studying MSc Nanotechnology and Regenerative Medicine at UCL. Although he has background in biology, he took the initiative to pick up computational skills through self-learning. In his final year research project, he spotted the potential of CUO while engineering a pipeline for gene optimization in C.reinhardtii’s chloroplast. Over one year, he expanded CUO from a humble codon usage analysis tool into a versatile open source bioinformatics software. He has a far vision for CUO but nevertheless possesses entrepreneur spirit to rise it up.
