Profile Summary

I am currently working as a Research Assistant. I specialize in applying data science, artificial intelligence, and numerical optimization techniques to real-world problems. With a strong foundation in Mechanical Engineering, Supply Chain Management and Data Science, I am well-prepared to tackle complex problems, drive innovation, and contribute meaningfully to scientific and technological progress. Throughout my career, I have been dedicated to helping companies and individuals grow by leveraging my expertise. I have had the privilege of working as a research associate at the Technical University of Munich, where I gained valuable experience in various aspects of engineering and data science. I am also certified by the Massachusetts Institute of Technology (MIT). I have supervised more than 8 BSc and MSc student theses, and reviewed for Elsevier and Springer Nature more than 100 times. I am also part of the Technical Program Comitteee of IEEE conferences.
