Prior to consulting, Koya held senior roles in industry, advising global pharmaceutical and healthcare companies and private equity firms on organizational transformation, R&D operating models and commercial strategy. He has led cross-border engagements and post-merger integration efforts, as well as commercial and medical transformations, often working across Japan, the U.S. and other international markets. Earlier in his career, he worked in global strategic consulting, investment banking and corporate development, supporting M&A transactions in healthcare and technology, and he began his career in the medical device sector.

“Life sciences companies are navigating increasing complexity across science, technology and global operations, while also facing pressure to improve productivity and speed to market,” said Koya. “L.E.K.’s strong heritage in life sciences strategy, combined with its growing capabilities in transformation and execution, creates a powerful platform to help clients address these challenges. I look forward to working with the team to deliver meaningful impact for clients across Japan and globally.”
