Machine Learning | LLMs & Agentic AI | Biomedical Data Science & Healthcare

Hi there, welcome to my website.

My story

I am a data scientist with 7+ years of bioinformatics engineering experience, now focusing on applied AI and machine learning. My work has always lived where data is noisy, high-dimensional, and consequential: clinical genomics, translational research, diagnostics, and healthcare analytics. A concise summary of this work is available on the Bioinformatics page.

My move toward AI and machine learning comes from both long-standing curiosity and a clear professional direction: intelligent systems are becoming central to scientific discovery, healthcare, and real-world decision support. I am especially interested in building models that are robust, interpretable, and useful beyond benchmarks.

Since fall 2025, I have been pursuing an MSc in Computer Science at Leiden University, specializing in Data Science. Building on my experience in biomedical research and data science, I am now particularly interested in LLMs, agentic AI, and trustworthy information retrieval, especially their applications in healthcare.
