Hazor is an expert in rock mechanics and rock engineering. He is mainly interested in the [[Deformation (engineering)|deformation]] of discontinuous rock masses in natural rock slopes or in man-made [[Tunnel|tunnels]], [[Dam|dams]], and open pit mines. In his work he utilizes analytical solutions for three-dimensional analysis such as block theory and [[Numerical analysis|numerical approaches]] such as [[Discontinuous deformation analysis|DDA]].<ref>{{Cite web |title=Block theorysystem andmodeling its applicationby todiscontinuous rockdeformation engineeringanalysis {{!}} WorldCat.org |url=https://search.worldcat.org/title/1048418527849539 |access-date=2024-0203-1206 |website=search.worldcat.org |language=en}}</ref><ref>{{Cite book |last=Shi |first=Gen-hua |url=https://books.google.com/books?id=U_ceAQAAIAAJ |title=Block System Modeling by Discontinuous Deformation Analysis |date=1993 |publisher=Computational Mechanics Publications |isbn=978-0-945824-38-1 |language=en}}</ref> At his laboratory he explores the relationship between [[microstructure]] and [[Mechanical engineering|mechanical]] behavior of [[Crystal|crystalline]] rocks,<ref>{{Cite journal |last1=Hatzor |first1=Y.
