Profile

Dr Morales' expertise is in intelligent algorithms, including control systems and machine learning, with his algorithms being deployed to a diverse industrial base, especially on rotorcraft. Dr Morales is at the cutting edge of designing, validating, and rolling out intelligent algorithms to support innovation and new competitive technologies. He has led several research projects and technological developments for future technologies and has worked in close collaboration with key industrial and government stakeholders. His algorithms have proven to provide the benefits of improved performance, reliability and autonomy. 

Dr Morales currently leads the Aerospace and Computational Research Group at the University of Leicester. To date, he has 40+ publications, including a book chapter, and has raised close to £1M in research and consultancy revenue directly.

Dr Morales is a founding member of a group of specialists in rotorcraft systems within the UK known as the UK Vertical Lift Network and he is currently the University Liaison Officer for the Vertical Flight Society's Chapter in the UK. He completed his PhD and MSc studies at the University of Manchester in 2008 and 2005, respectively.

Research

Robust flight control and Autonomy for future air vehicles: This research has a primary focus on vehicle configurations with distributed and/or rotor-based propulsion (e.g. tiltrotors, multicopters, drones, etc.). New rotorcraft configurations demand advanced control algorithms to meet stringent requirements around handling qualities, flight control and certification.

Intelligent algorithms for control, modelling and forecasting: this area of research is recent and combines key elements of machine learning and feedback systems to ensure high reliability.

Active Control: this research area is concerned with the development and implementation of advanced and comprehensive control systems to achieve reduction of vibration rotor power and noise in helicopters.
