Research Fellow - Data Science and Artificial Intelligence

Postdoctoral Research Fellow Position

Mayo Clinic is top-ranked in more specialties than any other care provider according to U.S. News & World Report. As we work together to put the needs of the patient first, we are also dedicated to our employees, investing in competitive compensation and comprehensive benefit plans to take care of you and your family, now and in the future. And with continuing education and advancement opportunities at every turn, you can build a long, successful career with Mayo Clinic.

A postdoctoral research fellow position is available at the Cancer Data Science Lab (PI: Dr. Irbaz Riaz) at Mayo Clinic in Arizona. The research fellow will work in a multi-disciplinary team of clinicians, data scientists and informaticians.

Dr. Riaz is an Assistant professor in medicine and biomedical informatics. His lab is focused on developing artificial intelligence (AI) methods for electronic medical records data. The current projects heavily emphasize natural language processing (NLP), large language models (LLMs), multi-modal data integration, and computation oncology.

This position (candidate) may engage in following projects:

• Training and implementation of large language models that demonstrate good performance with healthcare data.
• Utilize artificial intelligence techniques, including natural language processing such as large language models, computer vision and other deep learning methods, to build task-specific models for diverse applications in healthcare.
• Develop artificial intelligence frameworks for data extraction from free-text unstructured text reports and imaging/histopathological imaging data.
• Develop and/or improve predictive models using uni-modal and multimodal electronic health records system data (free text, imaging, genomics)
• Develop/enhance software for living clinical practice guidelines.
• Work with a multi-disciplinary team of physicians, computer scientists, and biomedical statisticians to improve artificial intelligence-based approaches for solving complex data science problems in cancer.
• Harbor excellent verbal- and written- communication and presentation skills.

A Research Fellow at Mayo Clinic is a temporary position intended to provide training and education in research. Individuals will train in the research program of a Mayo Clinic principal investigator. Qualified individuals will demonstrate the potential for research as evidenced by their training and peer-reviewed publications and should become competitive for national research grants. Proof of English proficiency is required for J-1 Short-Term Scholars, Research Scholars, Professors, Specialists, and Student Interns sponsored by Mayo Clinic.
