Nelson Sierra Sierra

I am a PhD researcher at KTH Royal Institute of Technology in the Department of Energy Technology, working within the Applied Thermodynamics and Refrigeration division.

My research focuses on optimizing energy efficiency, battery and drivetrain thermal management, and passenger thermal comfort in public electric buses. I combine experimental testing, IoT hardware prototyping, and machine learning methods to develop smarter thermal management strategies for electrified transport.

Before starting my doctoral studies at KTH, I worked extensively as an applications engineer in the HVAC-R and automotive industries. I hold master's degrees in Industrial Automation and Artificial Intelligence, along with a bachelor's degree in Mechatronics Engineering.

Research Interests

• Thermal management in electric vehicles and public transit

• Applied thermodynamics, refrigeration cycles, and heat pump systems

• Sensor telemetry, IoT prototyping, and hardware-in-the-loop testing

• Machine learning for system diagnostics and energy optimization

I am also teaching assistant for the course MJ2509 Energy in the built environment
