PostDoc on Targeted Proteomics for Protein Biomarker Standardization

About this position

Are you eager to translate cutting-edge targeted proteomics into standardized protein biomarker measurements for clinical diagnostics? Join an interdisciplinary academic-clinical-industry collaboration developing robust LC-MS/MS reference methods for lung cancer tumor markers.

The challenge

Protein tumor markers can support minimally invasive lung cancer diagnostics, but results from current immunoassays vary between platforms and laboratories. You will help close this standardization gap by developing and validating targeted mass-spectrometry workflows and reference measurement procedures for clinically relevant protein biomarkers, including CEA, NSE and CYFRA21-1.

Your role

You will conduct hands-on research in quantitative targeted proteomics, with emphasis on immunoaffinity enrichment, bottom-up LC-MS/MS and SISCAPA-based workflows. You will select and evaluate signature peptides, establish calibration strategies using stable-isotope-labelled standards, characterize reference proteins and peptides, and assess sensitivity, selectivity, recovery, matrix effects, precision, accuracy and robustness. You will compare candidate reference methods with commercial immunoassays and contribute to analysis of serum and pleural-fluid samples.

You will integrate activities across connected projects that aim to create a transferable platform for reference measurement procedures and materials for complex protein biomarkers. You will plan experiments, maintain high-quality and reproducible documentation, analyze and interpret quantitative data, prepare scientific publications and presentations, and contribute to method transfer, standard operating procedures and project reporting.

Research environment and collaboration

The position is embedded in the Laboratory of Chemical Biology, Department of Biomedical Engineering at Eindhoven University of Technology (TU/e), and in the regional Expertise Center Clinical Chemistry Eindhoven. You will work closely with researchers and clinical chemists at TU/e, Catharina Hospital and Máxima Medical Center, and with diagnostic and technology partners including Roche Diagnostics and SISCAPA Assay Technologies. You will also collaborate with PhD students and supervise Master and Bachelor students.

Expected impact

Your work will advance metrologically traceable and comparable protein biomarker measurements, support harmonization of tumor-marker testing across clinical laboratories, and establish methods that can be extended to biomarkers beyond lung cancer.
