Research interests

Dr Fernando Alonso-Marroquin's research into particulate systems - or materials made up of particles - has applications as diverse as improving the stability of the soils supporting our roads and railways and optimising the placement of exits in a room so a crowd can evacuate quickly in the event of an emergency.

"I study how the particles that make up particulate systems behave and interact under certain conditions.

"This includes investigating the responses of granular soils to the types of cyclic or vibrational loads they might be subjected to under heavy traffic flow, in the event of an earthquake or landslide, or under the movement of a structure such as a wind turbine. I observe how the particles move against and affect each other under such conditions.

"I also develop simulations of pedestrian and traffic flow using particle-based models, such as investigating how the number and placement of emergency exits in a room affects the speed and efficiency of evacuation.

"My focus is on fundamental research that will increase our understanding of how such systems operate. It involves the development of mathematical equations on paper that are then converted into computer scripts for numerical simulations. It aims to help us understand large-scale behaviours by looking at small-scale studies of particles and their behaviours and interactions under certain circumstances.

"I'm passionate about the use of maths to understand how complex systems evolve, based on the interaction of the parts they consist of. I'm also passionate about using high-end computer technologies to develop numerical modelling of complex systems.

"The biggest challenge I face is finding enough time to do all the research I want to do."
