Results-oriented AI Healthcare Specialist with 15+ years of experience.
What I'm looking for
I am a results-oriented AI Healthcare Specialist and Radiological Health Expert with over 15 years of experience in diagnostic radiology, radiation protection, and AI model training. My journey has been marked by a commitment to bridging hands-on clinical expertise with artificial intelligence to enhance healthcare and radiological safety solutions. I was promoted to Senior Reviewer at Outlier.ai within just six months, ranking in the top 5% for my precision in evaluating and refining large language models (LLMs).
Throughout my career, I have successfully reduced model error rates by 35% and improved diagnostic reporting speed and accuracy significantly. My role as a Senior AI Trainer at Outlier.ai has allowed me to collaborate with over 15 AI engineers, developing evaluation rubrics and QA protocols that are now adopted company-wide. I am passionate about mentorship and knowledge transfer, having trained numerous junior radiologists in radiation safety and imaging informatics, ensuring the next generation is well-equipped to handle the challenges in our field.
