Work

Ten years, from robotics labs to cell therapy.

Computer vision, spatial transcriptomics, and now single-cell multi-omics in clinical programs — building the methods and pipelines behind the decisions.

  1. Senior Scientist, Computational Biology

    Johnson & Johnson Innovative Medicine · Berlin, Germany

    Aug 2025 — Present

    Technical lead for single-cell multi-omics in oncology and immunology, from discovery through product development.

    • Lead single-cell multi-omics programs (transcriptomics, proteomics, spatial) that feed target selection, mechanism-of-action work, and translational strategy for oncology and immunology assets.
    • Set the analytical direction across several parallel projects: defining standards, reviewing methodology, and agreeing deliverables with clinical and discovery stakeholders.
    • Mentor junior scientists and manage external consultants, mostly through code review, design discussions, and onboarding.
    • Work with wet-lab, clinical, and CMC teams to turn analyses into experimental designs and go/no-go decisions.

  2. Data Scientist, Computational Biology

    Johnson & Johnson Innovative Medicine · Berlin, Germany

    Oct 2023 — Jul 2025

    Built the team's production analysis infrastructure and led single-cell projects across clinical and manufacturing programs.

    • Built automated Nextflow/Python pipelines for scRNA-seq, CITE-seq, and multi-modal analyses, replacing manual workflows that previously took days per dataset.
    • Led the single-cell analyses behind biomarker discovery for a clinical-stage cell therapy and process characterisation for CMC, including work that went into regulatory documentation.
    • Set up the team's reproducibility conventions — containerisation, version-controlled pipelines, shared QC standards — now the default for new projects.
    • Reviewed colleagues' analyses as the team's main technical reviewer.

  3. Doctoral Researcher — Computational Biology

    Max Delbrück Center for Molecular Medicine · Berlin, Germany

    Oct 2019 — Sep 2023

    PhD on open-source methods for spatial transcriptomics, now used by labs in academia and industry.

    • Designed and led Optocoder, a machine-learning pipeline for decoding barcoded transcripts from imaging-based spatial transcriptomics. Published in NAR Genomics & Bioinformatics and used by external labs.
    • Rewrote novoSpaRc (optimal-transport reconstruction of tissue architecture from scRNA-seq) for scale, making it usable on whole-tissue datasets. Co-authored the Nature Protocols paper.
    • Co-inventor on a US patent for 3D spatial gene-expression reconstruction.
    • Handled the full cycle for both tools: problem framing, method development, benchmarking, release, documentation, and user support.

  4. Visiting Scientist

    The Hebrew University of Jerusalem · Rehovot, Israel

    Feb 2023 — Apr 2023

    Short collaboration applying protein language models to agricultural biotech.

    • Ran an independent short-term project applying protein language models (ProtBERT) to find candidate anti-insecticidal proteins from raw sequence data, combining transfer learning with biological priors to prioritise candidates for validation.

  5. Machine Learning Research Engineer

    Coriolis Pharma GmbH · Munich, Germany

    Apr 2019 — Sep 2019

    Deep-learning system for pharmaceutical quality control.

    • Developed deep-learning models for automated particle detection and classification from flow-microscopy images used in biopharmaceutical QC.
    • Packaged the whole thing — ingestion, training, evaluation, reporting — as a Python/PyTorch/TensorFlow tool that internal scientists could run themselves.

  6. Research Assistant — Computational Neuroscience

    Max Planck Institute for Brain Research · Frankfurt am Main, Germany

    May 2018 — Sep 2019

    Multi-omics integration for activity-dependent neuroscience.

    • Applied supervised ML to activity-dependent changes in the neuronal proteome.
    • Built a multimodal integration and domain-adaptation pipeline linking proteomic and transcriptomic datasets — the cross-modality work I still rely on today.

  7. Undergraduate Research Assistant — Medical Robotics

    Ozyegin University Robotics Lab · Istanbul, Turkey

    2014 — 2016

    Real-time perception for an image-guided biopsy robot.

    • Developed real-time needle-tip localisation and tracking from ultrasound imaging for autonomous robotic control during biopsy.
    • Wrote the C++/CUDA interface connecting real-time image analysis to robot control.
