Profile Summary

I am an AI and Research Data Scientist with a PhD in Biomedical Engineering (McMaster University) and postdoctoral training at Mayo Clinic Arizona, currently based at St. Michael's Hospital (Unity Health Toronto). My work spans machine learning, clinical prediction modeling, and translational research across multiple disease domains — including oncology, neuroscience and neurotrauma, and musculoskeletal and bone health research. My experience includes developing and validating predictive models for traumatic brain injury outcomes, early disease detection using facial phenotyping and computer vision, prognostic modeling for neurosurgical conditions, and applied ML in oncology and osteoporosis research during my postdoctoral and doctoral work. I have led and contributed to grants from Mitacs, Brain Canada, and CQDM, and collaborate regularly with clinicians, biostatisticians, and trialists across Canadian and international institutions. Core competencies: Machine learning for clinical prediction (classification, regression, survival analysis) Computer vision and image-based phenotyping Biostatistics and epidemiological methods Scientific writing, grant development, and research design AI integration in clinical and hospital settings I take on freelance projects in statistical analysis, ML model development, research design consultation, systematic reviews, and scientific writing across oncology, neurology, orthopedics, and broader biomedical research.
