M42 appoints Dimitris Moulavasilis as new Group CEO
Abu Dhabi-based leading AI-powered healthcare company – M42 has appointed Dimitris Moulavasilis as the new Group Chief Executive Officer, effective immediately.
Dimitris succeeds Hasan Jasem Al Nowais, who steps down as Managing Director and Group CEO. Hasan will continue to serve on the company board after a successful tenure leading M42 and previously Mubadala Health.
In his new role, Dimitris—who joined M42 in 2024 as Chief Operating Officer—brings a wealth of leadership experience. He was also appointed CEO of Global Patient Care platform in January 2025, and he also joined Cleveland Clinic Abu Dhabi as a Board Member in March 2025. He will spearhead M42 in its purpose-driven mission and core values, continuing to lead healthcare innovation from the UAE to the world. His vision will steer M42 through its next phase of strategic growth and global expansion.
Announcing the transition, the company stated, “With deep institutional knowledge and a proven track record of operational leadership, innovation, digital transformation and growth, Mr. Moulavasilis' appointment ensures a seamless transition and continued momentum for M42.”
Extending wishes to the outgoing CEO Hasan, the company said: “Having led Mubadala Health after forming it as chief executive officer, including the acquisition of a 60 per cent stake in United Eastern Medical Services (UEMedical), Mr. Al Nowais was a founding figure behind the creation of M42 with the merger of Mubadala Health and G42 Healthcare in 2022. He has since played a defining role in shaping M42 into the AI-powered global health leader it is today, operating in 26 countries.”
“Under his leadership, M42 has grown 5x in seven years, expanding internationally with the acquisition of Diaverum in 2023 and through organic growth strategies in key markets; entering local and global partnerships; and, delivering exceptional patient outcomes, with numerous UAE and regional firsts in care,” it added.
Peng Xiao, Chairman of M42 and Group CEO of G42 also commented: “Building on the strong foundation established by Hasan, we are now entering the next chapter of M42’s journey. I want to sincerely thank Hasan for his visionary leadership and unwavering dedication in shaping M42 into the powerhouse it is today.
Looking ahead, we are excited to work with Dimitris, a seasoned leader with global experience, strategic depth, and a passion for innovation. His appointment marks an exciting new phase for M42 as we continue to advance the frontiers of healthcare through technology and world-class clinical excellence.”
Dimitris added: “It is a privilege to be entrusted with writing the next chapter for M42. I am proud to build on the strong foundation laid by Hasan and the leadership team. Together with our people, partners and patients, we will continue to push the boundaries of healthcare innovation, expand our global footprint and disrupt traditional healthcare models to accelerate the shift from sickness to prevention and positively impact lives locally and globally.”
Hasan said: “Over the past decade, we’ve built on the strong foundations at Mubadala Health to create a global health leader in M42, which has improved lives across borders and continues to make innovative strides to benefit all people, leaving no-one behind. I am confident that Dimitris will continue to drive this vision forward with the same passion, purpose and relentless pursuit of excellence.
I have unwavering confidence in M42’s strength and readiness for the next chapter. With a strong, integrated group structure and a deep leadership bench, M42 is exceptionally well positioned for the future. I look forward to supporting Dimitris’ efforts and M42 as a member of its Board.”
Before joining M42, Dimitris served Sweden’s Diaverum as the President and CEO, which was acquired by M42 in 2023. Now, Rafael Romanini has been appointed as the Group CEO of Diaverum.
In his previous roles, Dimitris worked with Affidea in the capacity of Group CEO for over 12 years, and GE Healthcare in key roles for around a decade.
