About Me

I'm a Work and Organizational Psychologist having several years of experience as a Data Scientist specialized in traditional Machine Learning as well as Deep Learning with competencies in MLOps. Currently, I'm actively pursuing continuous education and skill development in the field of Generative AI, especially Large Language Models (LLMs).

Within the field of Machine Learning, I am particularly - but not exclusively - interested in following subjects:

  • Generative AI
  • Natural Language Processing (NLP)
  • Computer Vision
  • Interpretable Machine Learning and Explainable Artificial Intelligence (XAI)
  • Reinforcement Learning
