Olesia Bratus - September 2026

Olesia Bratus

Olesia Bratus is a Project Manager, Business Consultant, and Coach from Ukraine.

For more than ten years, Olesia has worked at the intersection of business, people, and change. Her professional journey has included international development projects, business support, investment initiatives, and organizational development, giving her the opportunity to collaborate with Ukrainian companies and international partners.

Over the years, Olesia has come to realize one important thing: successful projects are built on more than solid plans and methodologies. They are driven by people who can collaborate, adapt to change, and make confident decisions in uncertain environments. That is why she combines project management, business consulting, and coaching in her work today.

Recently, Olesia has become particularly passionate about artificial intelligence. She is exploring how AI can become a practical tool for project managers and business leaders, helping them analyze information more efficiently, make better decisions, and free up time for the work that no algorithm can replace: developing people, building strong teams, and leading change.

Olesia joined the PMI Switzerland Chapter not only to learn, but also to build meaningful professional connections, exchange ideas, and connect with people who believe that the future of project management lies at the intersection of technology, leadership, and human potential.

Olesia looks forward to getting to know the PMI Switzerland community and having inspiring conversations.

Carlos Machahua - September 2026

Carlos Machahua

Carlos Machahua is a PMP-certified translational biomedical scientist and R&D project professional based in Bern. His expertise lies in Respiratory Medicine, particularly lung fibrosis, regeneration, biomarker research, and the evaluation of potential therapeutic approaches.

During his academic career in Barcelona and Bern, Carlos worked across fundamental, preclinical, translational, and clinical research, combining scientific investigation with the structured coordination of multidisciplinary projects. Most recently, as a Postdoctoral Scientist at Inselspital–University of Bern, he coordinated six research projects involving interstitial lung disease and COVID-19.

His responsibilities extended across the project lifecycle, from defining objectives, scope, milestones, timelines, resource requirements, and risks to coordinating laboratory teams, clinicians, biobanks, external research providers, industry sponsors, and international collaborators. Carlos also supported budget planning, monitored deliverables, maintained project documentation, and communicated results to scientific and funding stakeholders.

After completing his postdoctoral position, Carlos saw this transition period as an opportunity to prepare for his next professional challenge. Committed to continuous learning, he used the time to build on his previous project experience, broaden his understanding of project management, strengthen his business perspective, and formalise these capabilities by obtaining his Project Management Professional (PMP)® certification.

After receiving the welcome email from the PMI Switzerland Chapter, Carlos saw the “Introduce Yourself to Our Community” initiative as a valuable opportunity to introduce himself. Joining PMI Switzerland was a natural next step for him to continue learning, connect with the local project management community, and become more involved in Chapter activities.

In his free time, Carlos enjoys hiking, especially during spring and autumn, when Switzerland is at its best for exploring the outdoors. He also likes working out and staying active. In summer, he is drawn to water sports and, of course, swimming in the Aare. Carlos enjoys sharing dinners and board-game nights with friends, while also making time to improve his German through regular classes and practice.

Carlos would be particularly pleased to connect with professionals working at the intersection of science, healthcare, and project management. He also looks forward to exchanging experiences with other members and contributing to Chapter activities where his background in research, international collaboration, and life-sciences project coordination may be valuable.
