Received 10 distinctions for teaching and research excellence, including multiple Certificates for Best Pedagogical Practice from FEUP (2022, 2023, 2025), the Outstanding Research Practice Certificate (2024), the APMTAC Young Researcher Award in Applied and Computational Mechanics (2022), two Wolfram Mathematica Young Researcher Awards (2017, 2022), and the Best PhD Thesis Honourable Mention (2012). Developed six public datasets and over 150 numerical codes integrating advanced numerical methods and machine learning for industrial and academic applications. Created Python-based optimization tools for national energy networks (VALORAGUA, REN), finite-volume solvers for viscoelastic flows and polymer extrusion (Soprefa, Continental Mabor), vehicle dynamics simulations and high-fidelity VR simulators (BREUCA), and machine-learning-based industrial monitoring platforms (Neoadvance, Accenture). Participated in eight intensive scientific training activities in fluid mechanics and numerical methods and produced two scientific video resources. Led and contributed to seven major industrial projects, including VALORAGUA (2020–2025), developing Python-based hourly energy optimization tools used daily by REN. Coordinated BREUCA (2020–2023), a high-precision VR racing simulator with numerical modelling and optimization. Implemented numerical simulations for polymer extrusion dies in the Portuguese Industry and contributed to projects with Neoadvance, Accenture, and Continental Mabor, applying numerical methods and machine learning. Served as principal investigator in four research projects and team member in five others. Supervised (or is supervising) three PhD students in Mathematics on numerical methods for viscoelastic and fractional models and Neural ODEs, and guided nine Master’s students in Mathematics and Computation, covering machine learning, numerical methods, and industrial AI applications.

  1. The role of adaptive activation functions in fractional physics-informed neural networks. In this work, we use adaptive activation functions for regression fractional physics-informed neural networks (fPINNs) to approximate nonsmooth solutions. The adaptive activation function has better learning capabilities than the traditional one because it improves the convergence rate and solution accuracy. Our simulation results show that the adaptive parameter contributes less to the improvemen. 2024. Coelho, C.; Costa, M. Fernanda P.; Ferrás, Luís Jorge Lima. https://hdl.handle.net/1822/97174.

  11. A numerical method for the transient couette flow of a distributed-order viscoelastic fluid. This work presents a numerical method for the solution of two coupled distributed-order fractional differential equations, that appear in the pure tangential flow of fluids modelled by the Distributed-Order Viscoelastic Model. We prove the solvability of the method, and, perform numerical simulations of relaxation tests.. Supported by FCT - Fundacao para a Ciencia e a Tecnologia, through projects:. 2021.

  14. Optimisation approach for parameter estimation of the generalised PTT viscoelastic model. The exponential form of the original Phan-Thien and Tanner (PTT) model is often used to study complex viscoelastic fluids. Recently, a generalised version of the PTT model, that uses the Mittag-Leffler function to compute a new function of the trace of the stress tensor, was proposed. This new model adds one or two additional fitting parameters that allow for greater fitting capability. In this pa. 2021. Costa, M.
