2. Visiting this website

When you visit this website, your browser sends technical requests to the server on which the website is hosted. Information needed to deliver the requested pages and files is processed as part of those requests. Depending on the hosting configuration, server logs may include your IP address, the date and time of the request, the requested URL, technical response information, and information transmitted by your browser.

This processing serves to provide the website, maintain its technical functionality, and protect it against misuse. The legal basis is Article 6(1)(f) GDPR: my legitimate interest in operating a functional and secure website.

The website is hosted by STRATO GmbH. STRATO GmbH processes technical data in connection with the provision of the hosting service.

3. Contact by email

If you email me, I process the information you provide, including your email address, message, and any other details you choose to include, in order to respond to your enquiry.

The legal basis is Article 6(1)(f) GDPR: my legitimate interest in receiving and responding to enquiries about my research and this website. If your enquiry concerns steps before entering into a contract, Article 6(1)(b) GDPR may apply instead.

I retain correspondence for as long as necessary to deal with the enquiry and any resulting matter, unless a legal obligation requires longer retention.

4. Cookies, analytics, and external content

In its current configuration, this website does not use analytics or tracking tools, offer a contact form, or embed content from third-party websites. It does not intentionally set cookies. Stylesheets and images are served as part of this website; its typography uses fonts available on the visitor's device rather than fonts loaded from an external service.

5. Links to external websites

This website contains links to external websites, such as ORCID, Google Scholar, and GitHub. These are ordinary links, not embedded services. If you follow one of them, your browser connects to the destination website, whose operator is responsible for its own processing of personal data.

6. Your rights

Subject to the applicable legal requirements, you have the right to request access to your personal data (Article 15 GDPR), rectification (Article 16), erasure (Article 17), restriction of processing (Article 18), and data portability where applicable (Article 20). You may object to processing based on legitimate interests under Article 21 GDPR.

To exercise these rights, please contact me using the email address above. You also have the right to lodge a complaint with a data protection supervisory authority under Article 77 GDPR.

7. Changes to this policy

I may update this policy if the website or its data-processing practices change. The current version is available on this page.
