**Posting Period - January 28 to February 11, 2025**

**POSITION: Postdoctoral Fellow**

Applications of Machine Learning Methods to Synthetic Data Generation

**TERM**: Full-time (1.0 FTE) - 1 year contract, with possibility of renewal

**SALARY**: From $75,000 - $85,000 annually. Will be commensurate with skills and experience.

**REPORTS TO**: Dr. Khaled El-Emam, Senior Scientist

Children’s Hospital of Eastern Ontario Research Institute (“CHEO RI”) is the research arm of the Children’s Hospital of Eastern Ontario - Ottawa Children’s Treatment Centre (“CHEO”) and an affiliated institute of the University of Ottawa. We acknowledge that Ottawa is built on un-ceded Algonquin Anishinabek territory. The peoples of the Algonquin Anishinabek Nation have lived on this territory for millennia and we honour them and this land. CHEO is a beloved institution and workplace that is widely recognized for being an anchor in our community. CHEO RI works to create new knowledge and evidence to support CHEO in its provision of world-class care to our children. Our mission at CHEO RI is to connect exceptional talent and technology in pursuit of life-changing research for every child, youth, and family in our community and beyond.

**CHEO RI has an immediate requirement for a Postdoctoral Fellow.**

The CHEO Research Institute is fully integrated within the Faculty of Medicine at the University of Ottawa, which comprises several research-intensive Departments supporting a vibrant research and educational environment with strong foci in multiple health-related fields. Several health-related students and medical trainees complete portions of their education and training at CHEO.

The **Electronic Health Information Laboratory**(EHIL) was formed in 2004 at the CHEO Research Institute and is headed up by Dr. Khaled El Emam. EHIL conducts multi-disciplinary research to enable data sharing for secondary purposes and data-driven simulation. It is located at the Children’s Hospital of Eastern Ontario Research Institute. Our research results get applied in practice relatively quickly, so we get rapid feedback from practice to continue improving our work.

**RESPONSIBILITIES**

Under the general supervision of Dr. Khaled El-Emam, the Postdoctoral Fellow will:

- Use machine learning and deep learning techniques to generate synthetic data from real world data (RWD) and clinical trial datasets.
- Developing and improving synthetic data generation methods and metrics.
- Performing simulations to evaluate new methods and metrics.
- Developing and improving methods for protecting generative models and synthetic data.

**QUALIFICATIONS, SKILL AND ABILITIES**
- A recent PhD in statistics, computer science, applied mathematics, engineering, epidemiology or a similar discipline.
- Good knowledge of R and/or Python, and ideally PyTorch and/or Tensorflow;
- Previous work in statistical disclosure control, and in developing and evaluating machine learning models;
- Previous work training different types of deep learning models / architectures would be a plus.
- Ability to set priorities with competing and shifting demands;
- Willingness to learn and adapt to new policies, procedures and requirements;
- Ability to be flexible with working hours to meet deadlines.

**WORKING CONDITIONS**
- Possibility to work remotely or in a hybrid work model (remote and on-site).

**OTHER REQUIREMENTS**
- Eligible to work in Canada;
