Interdisciplinary expertise for better decisions
I help companies, universities and executives understand economic, legal, political and organisational connections — and translate them into clear options for action. With a name, not a chatbot.
Six consulting fields
Economics & markets
Economics and health economics, the German and European economy, economic policy and globalisation — as a grounded assessment for your decision.
Law & compliance
German and European business law, media, social and health law — critical questions explained in business terms (not individual legal advice).
Management & expansion
Business administration, marketing, project and process management, plus market entry and expansion — especially into German-speaking and European markets, practical for your team and organisation.
Europe, policy & regions
The EU and European integration, politics and society, regional identity and minority languages — Prof. Dr. Brandtjen’s research field, translated into orientation for your project.
International, digital & intercultural leadership
Leadership in international and intercultural contexts — across borders, in mixed teams at the same location, or in distributed teams collaborating digitally. Clarity in communication, collaboration and leadership across cultures and distances.
Languages & digital readiness in teams
Language training (German/Spanish) for teams and an assessment of how ready your team is to engage with digitalisation — with concrete recommendations for communication and collaboration.
From teaching to practice
Prof. Dr. Roland Brandtjen — a European-studies scholar with legal training and teaching and consulting experience across Germany, Spain and Europe. At bachelor and master level he has taught economics, business and tax law, management and European policy, among others. He brings these topics into your company as consulting, a workshop or a written briefing.
Connections, not isolated facts
Complex decisions rarely arise within a single discipline. Market shifts touch law and regulation. Internationalisation affects economics, politics, organisation and communication. Change within companies requires not only expertise but also an understanding of processes, leadership and a clear strategy. As a professor and interdisciplinary consultant, I combine these perspectives in a personal consultation. I don’t just analyse individual pieces of information — I make visible the connections that matter for your decision.
Clarity
Complex matters become structured and understandable.
Interdisciplinarity
Economics, law, politics, management and organisation are considered together.
Sound basis
Decisions rest on clear arguments and reliable information.
Practical focus
Academic expertise is translated into briefings, workshops and concrete options for action.
Empowerment
Employees and executives develop their own analytical and decision-making skills.
A personal partner
You work directly with a professorial expert, not an anonymous standard consultancy.
International reach
Content can be handled in German, English and Spanish contexts.
„You hire me when a question is too complex for a one-dimensional answer, but too concrete for purely academic theory.“
I am not a substitute for a specialised law firm, an auditing company or a classic strategy consultancy. My place is where subject-matter connections, scientific grounding, personal empowerment and practical orientation come together.
Three ways to work together
Consulting session
A personal appointment (in person or online) on a concrete question from one of the fields. For professionals and executives who need well-grounded information.
Workshop / in-house training
A tailored workshop for your team on one of the topics — compact, practical, in German, English or Spanish.
Briefing / short report
A written assessment of your question — structured, with sources and a clear conclusion. It carries a name: “Prepared by Prof. Dr. Brandtjen”.
Consulting sessions are billed by time; workshops and written briefings are tailored to your company and scope — so we quote after a short intro call. Small-business scheme (§19 German VAT Act, no VAT); payment via PayPal.
