    • Data Scientist / Biostatistician
      Jun 2024 - May 2025 · 1 yr

      Development of predictive biomarkers in pharma clinical trials; leveraging statistical methods, AI/ML and causal inference for characterizing molecular, biomedical and technical factors underlying biomarker performance and treatment response; complementary software development for analytical frameworks and LLM-based solutions implemented into scalable software packages and platforms.

  • PhD Candidate at Helmholtz Munich
    May 2019 - May 2024 · 5 yrs 1 mo

    Dissertation conducted with A/Prof. Dr. M. Menden; developing modelling strategies using statistical, machine learning, causal inference and AI methods for computational drug discovery and development in cancer. Specifically, I was working on computational drug and biomarker discovery with new multi-omics data modalities and methods in high-throughput drug screens, interpretable and translatable drug response prediction in pharmacogenomics, prioritising novel drug combinations through discovery of drug resistance mechanisms, prognostic prediction of cancer patients and the discovery of predictive biomarkers and causal estimation of heterogeneous treatment effects in randomised clinical trials and observational data. As an overarching goal, these and future efforts aimed at the discovery and modeling of drug response mechanisms for identifying new cancer vulnerabilities or treatment strategies for precision medicine.
