About Trialgrids

Trialgrids is built and maintained by Mehmet Şahin, a clinical research professional with experience in bioequivalence and bioavailability (BE/BA) studies. The tools were created to address the daily friction points encountered in BE/BA work — the manual Word workflows, the Excel hacks, the repetitive copy-paste-replace cycles that quietly steal hours from research staff every week.

Based in Gaziantep, Turkey. Serving researchers worldwide.

What to expect

When you write:

• Questions about the tools — I'll answer based on my own clinical research background and explain how to get the most out of each tool
• Feature suggestions — every suggestion is read carefully. Not all become features, but all inform the roadmap
• Bug reports — please include browser version, what you were doing, and what happened. I'll prioritize and follow up
• Partnership or commercial inquiries — happy to discuss

What this is not

Trialgrids is not a 24/7 support service. It's not a replacement for your institution's validated systems. It's a free toolkit, maintained as a side project alongside clinical research work.

If you're working on a regulatory submission and you spot something concerning in a tool's output, please verify against your protocol or sponsor's data management plan first, then let me know what you found.
