Postdoctoral in MiTag Single-Cell Proteomics and Mass Spectrometry
Transcription factors (TFs) are the master regulators of cell identity and fate, yet they have remained largely invisible to single-cell proteomics, expressed at levels too low for conventional mass spectrometry to detect. We are seeking a highly motivated Postdoc to join the Cell Diversity Lab at DTU Bioengineering to help change this, as part of the ProteoFATE project, funded by the Novo Nordisk Foundation Interdisciplinary Synergy Programme (2026–2030). ProteoFATE is a landmark interdisciplinary project that combines three world-class disciplines to make TF dynamics measurable for the very first time: AI-guided minibinder design (Jenkins Lab, DTU), cutting-edge single-cell proteomics by mass spectrometry (Schoof Lab, DTU), and primary human hematopoiesis (Porse Lab, University of Copenhagen / Rigshospitalet). Together, we will engineer novel MiTag reagents, minibinder-based signal amplification tools, enabling the first simultaneous, global, and quantitative readout of TF protein dynamics alongside the complete proteome in individual human blood stem cells. You will be the lead proteomics specialist for the project, serving as the critical bridge between the MiTag reagents engineered in the Jenkins Lab and their deployment on primary human cells with the Porse Lab. Your focus will be to push the boundaries of what single-cell proteomics by mass spectrometry (scp-MS) can detect, developing workflows that simultaneously capture global proteomes and multiplexed MiTag signals from individual cells. This position provides exceptional interdisciplinary training, spanning mass spectrometry, AI-guided protein design, and stem cell hematology, within a highly collaborative consortium tackling a question that has resisted measurement for decades. Responsibilities and qualificationsYour overall focus will be to design, optimize, and deploy scp-MS workflows that reliably detect MiTag-derived peptides alongside global proteomes in primary human hematopoietic cells, establishing the quantitative and technical foundation on which the entire ProteoFATE project depends. This is fundamentally an LC-MS-driven role with direct biological impact: you will be among the first in the world to quantify transcription factors at single-cell resolution using mass spectrometry. Your core activities will include: Develop and optimize DIA-based scp-MS acquisition methods on the Orbitrap Astral that simultaneously capture global proteomes and multiplexed MiTag peptides in a single run, including hybrid DIA (iDIA) strategies for targeted MiTag readout alongside untargeted proteome acquisition Optimize fixation and permeabilization protocols for intracellular MiTag staining in human CD34+ HSPCs, compatible with downstream high-sensitivity scp-MS Rigorously benchmark MiTag performance in terms of sensitivity, specificity, throughput, and quantitative reproducibility, validated against orthogonal assays such as intracellular FACS and CITEseq Investigate the multiplexing capacity of MiTags and characterize the relationship between signal amplification and TF detection sensitivity across the hematopoietic hierarchy Work in an iterative feedback loop with the Jenkins Lab (MiTag design) to guide reagent refinement based on MS performance, and with the Porse Lab to transfer optimized workflows to primary human bone marrow samples Dissemination of results through publications in leading journals and presentations at international conferences (e.g. ASMS, HUPO, EuPA, iSCMS, etc.) Mentoring of junior lab members (BSc., MSc. and PhD students) and active contribution to the collaborative culture across DTU and KU You are expected to have: PhD in biochemistry, (bio)analytical chemistry, cell biology, or a closely related field Extensive hands-on experience with LC-MS/MS-based proteomics, including at least 2–3 years of daily operation of high-end instruments (Orbitrap series strongly preferred) Strong track record in DIA-based proteomics workflows, ideally including wide-window/WISH-DIA or hybrid targeted/untargeted acquisition strategies (iDIA, SureQuant, or equivalent) Demonstrated experience in single-cell proteomics (scp-MS), including low-input sample preparation, single-cell isolation, and liquid handling automation Proficiency in computational proteomics data analysis (DIA-NN, MSFragger, Spectronaut, or equivalent) and downstream analysis in R or Python Documented ability to drive independent research from conception through to publication Excellent written and oral communication skills in English Experience with any of the following is highly desirable: Targeted proteomics approaches (SRM/PRM, SureQuant IS, or reagent-based enrichment of low-abundance proteins) FACS-based cell sorting, intracellular staining, or CyTOF/spectral flow cytometry Mammalian cell culture, including primary hematopoietic cells Integration, analysis and interpretation of larger single-cell datasets (preferably scp-MS) As a formal qualification, you must hold a PhD degree (or equivalent).
