About me

Professional background

As a multilingual Mediator, Ombuds and Coach with over 10 years of experience, I support individuals, teams and organisations in navigating challenges across cultural contexts, offering services in English, Spanish, French, and German (native).

 

Since September 2026, I serve as Ombuds at the Cherenkov Telescope Array Observatory (CTAO). As the organisation’s inaugural Ombuds, I established the Ombuds Office from the ground up, developing its policy framework, operating model and procedures. I provide confidential, neutral, impartial and independent support to staff across the Bologna, Berlin/Zeuthen and La Palma (Canary Islands) sites, by facilitating informal dispute resolution and providing conflict coaching. I also contribute to organisational learning by providing systemic feedback to leadership and producing an anonymised annual report. I report directly to the Director General while safeguarding the independence and confidentiality of the Ombuds function.


From 2021 to 2026, I served as Internal Mediator at the Organisation for Economic Co-Operation and Development (OECD) in Paris, reporting directly to the Secretary-General. In this role, I provided workplace mediation, dialogue facilitation and individual conflict coaching, while advising on workplace culture and recurring staff concerns. Capacity-building and training were integral to my work at the OECD. A conflict prevention and resolution training programme that I co-designed from concept through implementation is now mandatory for more than 4,700 staff members.


I have previously gained diverse and hands-on mediation experience in peace mediation working in inter-community conflicts and multi-stakeholder dialogue processes for the United Nations Peacekeeping Mission in Côte d’Ivoire. My mediation journey began as a Project Manager in commercial mediation at the Centre for ADR of the International Chamber of Commerce in Paris. 


At UWC International I was Head of Programme Development and Safeguarding and worked closely with the Executive Director and the UWC International Board. As a member of senior management I led a diverse global team with a broad portfolio ranging from fundraising and building up major donor programmes to coordinating mental health and wellbeing programmes for both young people and staff. I also managed internal complaints and conflict resolution processes as well as highly sensitive safeguarding/child protection reports as the organisation’s Safeguarding Officer after coordinating the drafting of a new safeguarding policy and setting up a reporting system.

Early in my career I worked for the German Parliament in international relations and completed my bar training with the Near East Department of the German Foreign Office in Berlin and at the Permanent Mission to the UN in New York in Human and Social Rights.

 

By background, I am a fully qualified German lawyer with a French-German law degree (Ludwig Maximilians University, Munich and Panthéon-Assas University, Paris).

Approach and values

My work is all about human connection and I am guided by professional and ethical standards set by CEDR, IMI, IOA and ICF.


In both mediation and coaching clients are at the centre of the process and can expect to be met with unconditional positive regard (Carl Rogers) and transparency in a judgement-free space.

 

My practice is grounded in humanistic values, with a focus on empathy, compassion, self-actualisation, and continuous learning.
