- Identify, access, and integrate diverse data sources, including clinical study data, observational data, and real-world healthcare datasets, ensuring high-quality data extraction and pre-processing.
- Develop and implement signal processing methods for data curation and feature/pattern extraction from longitudinal data, with particular focus on high frequency data (e.g., electrophysiological and wearable signals), for clinical and research applications.
- Develop and implement machine learning models for clinical applications, including disease phenotyping, and predictive modelling.
- Apply advanced computational techniques such as time-series analysis, feature engineering, and probabilistic modeling to enhance biomedical data interpretation.
- Develop and maintain scalable, high-performance data pipelines systems that align with business needs and industry best practices.
- Validate and benchmark machine learning models against established state-of-the-art methods, ensuring clinical relevance and interpretability.
Reasons to use Rodeo
I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?
Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.
Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
