Ataklti Tesfay’s Award-Winning Research on Clay Architecture in Tigray: Environmental Physics of Heritage Preservation
Ataklti Tesfay investigated how temperature, humidity, and solar radiation drive the deterioration of traditional clay houses and monasteries in East Tigray, Ethiopia. His research integrated thermodynamics, materials science, and climate analysis to quantify how environmental stresses cause micro-cracking and surface erosion in earthen structures. Through laboratory simulations using locally sourced clay, he identified humidity cycling as the dominant factor in decay. The project earned national recognition for advancing scientific understanding of cultural preservation and sustainable heritage management in Ethiopia.

Ataklti Tesfay — 1st Place Winner, 2024
The Ethiopian High School Research Challenge is a nationwide platform that celebrates young innovators tackling real-world scientific and engineering problems. Participants advance through regional and national stages, where projects are evaluated by leading experts from universities and research institutions.
In the 2025 competition, Ataklti Tesfay won 1st Place for his project titled “Environmental Physics of Clay Material Deterioration in Traditional Architecture of East Tigray.” His research combined two years of regional climate data with laboratory experiments to reveal how cyclic humidity variations and thermal expansion accelerate the decay of earthen walls used in Ethiopia’s heritage architecture.
Ataklti’s work stood out for its interdisciplinary depth and cultural impact, demonstrating how physics can guide sustainable conservation strategies for post-conflict regions. His findings provide a scientific foundation for protecting Ethiopia’s architectural heritage while strengthening community-based restoration and tourism initiatives.
The Ethiopian High School Research Challenge continues to empower students to apply science and engineering toward national development, sustainability, and innovation.
