Learn More About Me
My interest in the natural sciences was shaped early on — growing up in a family where scientific thinking and health-conscious living were deeply embedded values. My grandmother’s emphasis on regional and seasonal foods sharpened my awareness of the profound role nutrition plays in health from a young age.
With biology, chemistry, and mathematics as my strongest subjects, my path quickly became clear: I wanted to understand how the human body functions at the cellular level — and how nutrition influences health, resilience, and long-term well-being.
That intellectual curiosity continues to drive me today. I am committed to continuous learning and expanding my expertise. Alongside my current Master’s studies in Entrepreneurship, I have earned certifications in the United States as a Functional Nutrition Coach and Fitness Instructor. I also continuously deepen my knowledge in emerging fields such as sensor technology, artificial intelligence, and digital health solutions.
My research interests focus on precision medicine and personalized nutrition concepts — translating scientific insights into individualized prevention and therapeutic strategies.
I strongly believe in overcoming siloed thinking and advancing interdisciplinary approaches — particularly in a fast-moving, technology-driven environment that demands innovative and sustainable solutions.
Scientifically rigorous yet practically applicable — this defines my work at the intersection of nutritional research, prevention, and product development. My goal is to make the complex interconnections between nutrition, health, and lifestyle tangible and actionable, contributing to measurable improvements in quality of life.
My philosophy: A healthy lifestyle is the foundation for personal growth — physically, mentally, and professionally. Continuous development enables not only resilience in the face of challenges but also the ability to create lasting impact.
Outside of my professional work, I recharge by spending time in nature, staying physically active, and sharing meaningful moments with family and friends — relationships that inspire and ground me. This balance between professional ambition and personal well-being is essential to sustaining creativity, focus, and long-term energy.
Let’s explore how science, nutrition, and innovation can work together to shape a healthier and more sustainable future.

Scientific & Regulatory Considerations
DİSPLAY:NONE
Why is scientific evidence important for a product?
How can scientific evidence be generated for a product?
What is the difference between a clinical study and a pilot or feasibility study?
Clinical studies, by contrast, are designed to systematically generate robust data on defined clinical endpoints under controlled conditions.
At what stage of product development is scientific advisory support advisable?
Scientific advisory support is most valuable in early stages of product development. An evidence-based strategic orientation enables informed decisions regarding ingredients, dosages, and mechanistic rationale, while helping to prevent later reformulations, delays, or regulatory complications.
Early integration of scientific expertise can create a defensible foundation for development while optimizing long-term time and resource allocation — without pre-empting regulatory evaluations or claims. e Aussagen oder Versprechen vorwegzunehmen.
Do you support the planning and execution of scientific studies?
Depending on study design and objectives, implementation may take the form of feasibility or pilot studies, or — for defined clinical endpoints — be conducted in collaboration with clinical centers or contract research organizations (CROs).
What added value does scientific evidence provide for marketing and sales?
This strengthens product positioning and facilitates professional argumentation, particularly in B2B contexts.
Is your advisory service only relevant for large companies?
The scope and depth of scientific support are tailored to the product, development phase, and organizational structure.
Do you support the development of new formulations from the outset?
The focus is on establishing a robust scientific rationale to support product development, communication strategy, and subsequent regulatory processes.
The drafting or formulation of health claims is not part of the service offering.
Do you also work on existing products and reformulations?
Laboratory analyses are not conducted directly. Where required, qualified partner laboratories can be integrated and scientifically supervised.
Who owns the rights to generated data and results?
In most cases, these rights remain with the client. Transparent agreements ensure security and clarity for all parties involved.
How is the protection of sensitive data and GDPR compliance ensured?
Project-related information is treated confidentially, used exclusively for its intended purpose, and protected through appropriate non-disclosure agreements (NDAs).
