Design develop and implement machine learning and deep learning models to analyze data from wearable sensors (e.g. activity trackers continuous glucose monitors) and echocardiography images.
Develop and validate algorithms for feature extraction pattern recognition and predictive modeling using wearable and imaging data.
Integrate and analyze diverse clinical datasets including electronic health records (EHRs) genomic data and patient-reported outcomes alongside wearable and imaging data.
Collaborate with clinical teams to define research questions and identify opportunities for leveraging data science to improve clinical trial design patient monitoring and disease understanding in rare diseases.
Develop and maintain robust data pipelines for processing cleaning and analyzing large-scale datasets.
Contribute to the development of visualization tools and dashboards to effectively communicate findings to both technical and non-technical audiences.
Stay abreast of the latest advancements in machine learning AI and data science particularly in the context of healthcare and digital biomarkers.
Document methodologies results and findings clearly and concisely.
Ensure compliance with relevant regulatory guidelines and data privacy standards.
Process Improvement:Actively contribute to the development of standard processes aimed at enhancing the quality efficiency and effectiveness of the Clinical Bioinformatics group.
You will need to have:
Ph.D. degree in Data Science Biostatistics Computer Science Biomedical Engineering or a related quantitative field.
2-4 years post-doctoral of hands-on experience applying machine learning and statistical modeling techniques to real-world datasets preferably within a clinical research or healthcare setting.
Demonstrated experience working with data from wearable devices (e.g. accelerometers heart rate monitors sleep trackers) and a strong understanding of signal processing techniques.
Experience in analyzing medical imaging data particularly echocardiography including image processing feature extraction and the application of computer vision techniques.
Proficiency in programming languages such as Python and R along with relevant libraries for data manipulation statistical analysis and machine learning (e.g. pandas NumPy scikit-learn TensorFlow PyTorch).
