    Hello! I'm Basel (Yes! the Swiss city was named after me :D), currently delving deep into the world of machine learning and operations research as I pursue my PhD at TU Delft, but I started 4 years ago during my MSc studies. Beside my PhD, I work as a junior research engineer at AIT GmbH. Based in Vienna, I find myself constantly fascinated by the ever-evolving landscape of technology and its applications in energy systems and algorithmic trading. When I'm not immersed in research, I enjoy composing and orchestrating music. My journey into the fields of AI and OR was fueled by curiosity, and I'm passionate about leveraging this expertise to drive innovation and efficiency in the projects I undertake.
