Marcos joined the Division of Thermal and Fluids Engineering on 1 June 2011 as an Assistant Professor. He graduated with BEng (First Class Hons) and MEng degrees in Mechanical Engineering from the Nanyang Technological University in 2003 and 2005, respectively. He then went for his doctoral studies at the Massachusetts Institute of Technology and obtained his PhD degree in Mechanical Engineering in 2011. His PhD study focused on the effects of fluid dynamics on swimming bacteria.

  • Interest:
    Small scale fluid dynamics, microfluidics, swimming in non-Newtonian fluids, and bio-locomotion
  • Projects:
    Metabolite profiling of malaria parasites by means of magnetic resonance imaging/spectroscopy
    We developed a malaria diagnosis technique which combined microfluidics separation of malaria infected red blood cells (iRBCs) with magnetic resonance relaxometry (MRR) system. The iRBCs are separated from the uninfected healthy red blood cells (hRBCs) through a phenomenon known as margination.

    Characteristics of Swimming microorganisms in Flow
    We developed a model to investigate the effects of shear flow on the shape of 2D propulsion flagellum, as well as hydrodynamic parameter of a single-flagellated microorganism such as sperm. The analytical results showed that under certain conditions, the shear flow could help the swimmer to swim faster.
