Manu Ignatius



I am an engineer by profession and a photographer by passion. I love to build stuff and when I am not building, I love to click.


Currently, I am the CEO of Subnero, a Singapore based company that specializes in providing underwater communications and networking technology & solutions. At Subnero, we develop underwater communications, navigation and monitoring & sensing systems along with commercializing the technology developed at Acoustic Research Laboratory (ARL), National University of Singapore, of which I was part of.

When I am not thinking about underwater communication networks, I do take up freelance photography and videography assignments, in and around Singapore. Head over to my photography page for more details.

I am also a passionate 'electronic' gamer and naturally have interests in computer graphics, graphics processors, graphics designing etc. Some of my other interests are scuba diving, traveling, scale modeling etc.

Photography is my passion. While my work at Subnero pushes me to see things the way they are, photography enables me to express myself the way I would like the world to be. I do freelance photography & videography assignments. You can find my portfolio here.
