About Dhanial

Senior Human Factors Engineer with 5+ years of experience helping MedTech companies design intuitive, safe, and compliant medical devices. I bring deep expertise in usability engineering per IEC 62366-1, risk management aligned with ISO 14971, and regulatory compliance with EU MDR.

I support the full HFE lifecycle—from Use Specification and Task Analysis to Use-Related Risk Analysis (URRA), formative studies, and summative usability validation—ensuring identification and mitigation of critical tasks and use errors. I integrate Human Factors into design controls, labeling (IFU/QRG), and verification/validation activities to meet FDA and EU expectations.

Additionally, I drive post-market usability activities, including Known Problem Analysis (KPA), complaint trending, and proactive risk identification using sources such as MAUDE and vigilance databases.
