Mr. Juan Camilo Londoño Alfaro is a Test Engineer at the Brake Excellence Center in the R&D department of Volkswagen AG, Germany. He received his Bachelor's degree in Mechanical Engineering in 2018 and his Master's degree in Aerospace Engineering in 2021, both from the Technical University of Braunschweig, Germany. Mr. Londoño Alfaro began his PhD in 2021, focusing on developing and integrating laser optical metrology for the visualization and characterization of brake wear particles. His research has been presented at various conferences, including the "29. Experimentelle Strömungsmechanik" in Ilmenau, Germany, the 12th Euro-Mediterranean Symposium on Laser-Induced Breakdown Spectroscopy in Porto, Portugal, and EuroBrake 2024 in Mainz, Germany. His work has provided valuable tools and data to better understand the ejection, mixing, and transport processes of brake wear, as well as to validate CFD models. Currently, his research focuses on using the developed methods to analyze the uncertainty sources during brake emission testing according to the GTR24 standards.
