Alan's scientific interests include:

• design of animals for high speed locomotion and factors limiting athletic performance;
• innovative measurement techniques for studying animals during field locomotion;
• muscle-tendon interaction in locomotion;
• diagnosis, assessment and treatment of locomotor dysfunction.

The beating wings of mosquitoes produce, simultaneously, aerodynamic forces, and the acoustic signal (the buzz) that guides their reproductive behaviours. Marcos investigates mosquito aerodynamics, mosquito acoustics, and the interdependency of the two, using an array of methods ranging from computational fluid dynamics to laser Doppler vibrometry.
