Research Overview

I have a strong interest in Fluid dynamics, specifically in the field of microfluidics. My previous research in Singapore focused on the theoretical analysis of frequency and time dependent electroosmotic flows in microchannels.
 
Currently, I am investigating the effect of fluid dynamical environment on swimming behaviour of microrganisms. We are able to generate micro-vortices using a microfluidic setup, with which we can accurately control and visualize the flow and swimming of these organisms. More interestingly, I would be keen to investigate what happen to the behavior of these microorganisms when nutrient gradients are present in the flow.

Fun Facts
Believe it or not, my full name is Marcos. Yupe! That’s me. I don’t have a last name.
 
I love food. Spent too much on food and will definitely go the distance for great food. I haven’t figured out if I eat to live or live to eat.
