About

Mattieu Haddad is a leading urological researcher whose work has fundamentally reshaped our understanding of laser–tissue interactions in minimally invasive surgery. His primary research areas center on the biophysics of Holmium:YAG and Thulium fiber lasers, with a specific focus on the true ablation and incision dynamics in soft tissue. Haddad’s most impactful contribution, "The True Ablation Effect of Holmium YAG Laser on Soft Tissue" (2018, 53 citations), challenged a long-held clinical dogma by demonstrating that the widely cited 0.4 mm penetration depth refers to energy absorption, not the actual incision depth achievable in tissue. This distinction has profound implications for surgical precision and safety, directly influencing laser settings in lithotripsy and enucleation procedures. By clarifying the physics behind laser ablation, Haddad has provided urologists with a more accurate framework for predicting tissue effects, thereby improving procedural outcomes. His work bridges the gap between theoretical physics and clinical practice, earning him recognition as a key voice in laser endourology. For students and researchers, Haddad’s studies serve as a vital reminder that foundational physical principles must be rigorously validated in biological contexts to advance surgical technology.
