Abdullah Al-Yaari

A research scientist with a Ph.D. in Applied Science (Mathematics) from Universiti Teknologi PETRONAS, specializing in mathematical modeling, fluid mechanics, and numerical methods. My expertise includes using techniques like the Finite Element Method (FEM) and the Finite Volume Method (FVM) to solve complex partial differential equations in engineering and applied sciences. Currently, at Central South University, I focus on inverse problems, applying advanced machine learning techniques such as Convolutional Autoencoders (CAE), Adversarial Autoencoders (AAE), and Variational Autoencoders (VAE) to enhance oil recovery. I have contributed to numerous research projects and publications and have held leadership roles, fostering academic collaboration and mentoring.
