I am a passionate research scientist, applied mathematician, and mechanical engineer dedicated to exploring dynamic systems. Specifically, I focus on investigating intricate fluid-structure interactions and the phenomena of ember storms during bushfires. My passion lies in utilizing nature-inspired insights to drive technological advancements for the betterment of our world. A key aspect of my research involves strengthening computational technologies to tackle the inherent complexity of various problems. Through high-fidelity computer simulations, I aim to enhance our comprehension of natural phenomena and find solutions to real-world challenges.

My research is primarily centred around computational fluid dynamics. I have been strengthening the fundamental understanding of the flow-induced vibration phenomenon of bluff solid bodies from various perspectives. I have developed several efficient and stable numerical techniques to study complex fluid-structure interactions. I am investigating the dynamics of ember storms during bushfires and exploring sustainable methods to mitigate ember hazards in the wildland-urban interface. My expertise spans a wide range of areas, including:

  • Utilizing computational fluid dynamics to investigate dynamical systems, including fluid-structure interactions, flow-induced vibrations, wake unsteadiness, bluff-body aerodynamics, birds and insect flight dynamics, ember storms, acoustics, and environmental flows.
  • Development of advanced numerical techniques to study complex dynamical systems, with experience in utilizing immersed boundary methods, lattice Boltzmann methods, spectral element methods, and finite volume methods.
  • Research interests in systems and control, optimization, robotics, and bio-mathematics.


I am an enthusiastic tertiary lecturer who is passionate about integrating my research into teaching materials. With teaching experience in mechanical and aerospace engineering, as well as mathematics and statistics subjects, I strive to provide engaging and relevant education that bridges theory and practical applications. My goal is to inspire and empower students by connecting classroom concepts with real-world applications, fostering a deeper understanding and appreciation for the subjects I teach.

Scholarships of $35,000 (AUD) are available for PhD applicants who achieved H1 (High Distinction) in their undergraduate programme and/or have completed a Masters by Research. If you are interested, please contact me at m.rajamuni@unsw.edu.au.
