Multi-omics integration to unveil the molecular signatures and environmental determinants of early-life blood pressure trajectories
The Barcelona Institute for Global Health (ISGlobal) is a cutting-edge institute addressing global public health challenges through research, translation into policy and education. ISGlobal has a broad portfolio in communicable and non-communicable diseases including environmental and climate determinants, and applies a multidisciplinary scientific approach ranging from the molecular to the population level. Research is organized in five programs: Climate, Air Pollution, Nature and Urban Health; Environment and Health over the Lifecourse; Global Viral and Bacterial Infections; Malaria and Neglected Parasitic Diseases and Maternal Child and Reproductive Health. ISGlobal is accredited with the Severo Ochoa distinction, a seal of excellence of the Spanish Science Ministry.
WHAT WE ARE LOOKING FOR
ISGlobal is seeking a bioinformatician who is interested in taking over and managing research activities of the project HELIX during 1 month. The project aims to prospectively assess the association between a wide range of environmental exposures and blood pressure trajectories, and evaluate their impact in molecular multi-omics signatures, in children from the European HELIX cohort.
KEY RESPONSIBILITIES
- Data Preparation and Exploratory Data Analysis (EDA): Conduct an extensive EDA to ensure data harmonization, cleaning, and preparation for analysis.
- Exposome-Wide Association Studies (ExWAS) for Single-Exposure Models: Perform ExWAS to evaluate single-exposure associations while correcting for multiple testing.
- Development of Multi-Exposure Models: Develop models to evaluate the simultaneous effects of multiple exposures, addressing co-exposure issues.
- Longitudinal Modelling of Time-Varying Exposures and Outcomes: Develop models to account for time-varying exposures and their relationship with outcomes over time.
- Results Reviewing and Sensitivity Analyses for Results Refinement: Perform sensitivity analyses to ensure robustness and revise results through re-analyses and subgroup testing.
SPECIFIC DUTIES
- Clean data (imputation, outliers, duplicates, error checking, etc.).
- Transform data (z-score normalization by sex).
- Adjust for confounders (identification and residualization).
- Perform correlation analysis.
- Conduct cross-sectional and prospective ExWAS analyses with correction for multiple testing.
- Apply sPLS models.
- Review results and perform sensitivity analyses (e.g., subgroups by sex).
