About Us

Evidence, designed for decisions.

Evidence by Design exists so that health decisions — funding, policy, treatment, pricing — rest on evidence that was built honestly and can be checked by anyone.

Our mission

Make rigorous evidence the easy option.

Too many health decisions are made on weak numbers — not because researchers don't care, but because rigorous methods are hard to access. We lower that barrier three ways:

  • Open tools — free calculators, templates, and code anyone can use and inspect
  • Teaching — a community and learning hub that trains the next generation of epidemiologists and health economists
  • Consulting — hands-on support when the stakes demand expert eyes

What we stand for

  • Transparency Every assumption named
  • Reproducibility Results rebuilt from raw data
  • Access Core tools free, forever
  • Capacity Skills stay with your team
Founder

Dr. Tariku Jibat Beyene

Educator, researcher, and consultant specialising in veterinary epidemiology, disease-burden analysis, and health economics — widely recognised for highly-cited global health research and his academic contributions at Addis Ababa University.

His work bridges rigorous method and real-world decision-making: estimating disease burden where data is scarce, modelling cost-effectiveness for policy, and training the next generation of epidemiologists and health economists.

How we're funded

Consulting pays the bills. Donations keep it open.

Consulting engagements and memberships fund the practice — and donations let us keep the calculators, templates, and training materials free for students and researchers in low-resource settings.

  • Every free tool stays free — no paywall creep
  • Donations directly subsidise training and open resources
  • Code and methods published openly on GitHub
