Head of the Chair of Concrete Structures and Infrastructures Engineering:

Patricio Quintana Gallo is a civil engineer and obtained his MSc in Civil Engineering from Federico Santa María Technical University in Valparaíso, Chile. He earned his PhD in Civil Engineering from the University of Canterbury, Christchurch, New Zealand, in 2015, focusing on seismic assessment and retrofit of non-ductile reinforced concrete structures, and including shake-table tests of a 3-storey frame building, as-built, and GFRP-retrofitted. During his doctorate, he also experienced the 2010 Chile and 2011 New Zealand earthquakes, where he participated in structural inspections and reconnaissance. He was a Research Associate at the University of Canterbury, a Structural Engineer at BRANZ Limited, and later an Associate Professor at the University of Valparaíso in Chile. In 2022, he received a Postdoctoral Fellowship at the Czech Technical University in Prague, and in 2025, he joined the University of Rostock. His research interests include the design, assessment and retrofitting of reinforced concrete structures for earthquake and extreme dynamic actions, anchorages in concrete subjected to extreme loading, seismic protection of connectors and anchors, and the development and analysis of timber-concrete and timber-steel hybrid structures. In addition to research, Dr. Quintana Gallo has experience designing and retrofitting multi-storey buildings against seismic actions.

Mr. Christian Meier has been working as a research assistant at the Chair of Concrete and Masonry Structures at the University of Rostock since April 2024. His tasks include both teaching and research, as well as administrative activities at the chair. He studied civil engineering at the University of Wismar and completed his studies in 2010 as a Master of Engineering with a specialization in structural engineering. Before joining the Chair of Concrete and Masonry Structures, Mr. Meier worked as a project engineer and project manager in the field of structural engineering and bridge construction.
Mr. Meier gained experience in the engineering offices Inros-Lackner and Böger & Jäckle. His work involved large projects in all stages of structural design from preliminary and detailed design to implementation design, structural analysis and validation of existing bridges. He gained experience in university teaching through teaching assignments at the University of Wismar.

Mr. Meier qualified as a structural inspection engineer in accordance with DIN 1076 and successfully completed a diploma degree in economics in addition to his work as engineer. Prior to his academic career, he completed his vocational training as a carpenter with distinction and worked for several years in furniture construction, interior design, restoration of Sacred buildings and redevelopment of administrative and residential buildings.
Experience as a civil engineer was gained in the following projects, for example:

• Replacement bridge in the course of Fackenburger Allee over Deutsche Bahn tracks, Hanseatic City of Lübeck
• New railroad overpass and trough structure in Rheine, Steinfurt district
• Replacement bridges to repair the A 20 embankment at Tribsees, Vorpommern-Rügen district
• Replacement construction of the 1st Peuter Bridge (HPA), Free and Hanseatic City of Hamburg
• Replacement construction of the Stör bridge A 23 near Itzehoe, Steinburg district (here also dismantling of the old Stör bridge)
• Structural analysis and verification of load-bearing capacity and serviceability in accordance with recalculation guidelines, e.g:

           - Uttrichshausen viaduct, A 7 near Fulda (here also structural design for dismantling)

           - Structure 487-2, A 1/Fünfhausener Landweg, Free and Hanseatic City of Hamburg

           - Mühlenbach viaduct, structure 633, A 7/Maldfedstraße, Free and Hanseatic City of Hamburg

           - Structure 7156, B 437/A 29 in Varel, district of Friesland (here also proof of the announcement behavior)

• Chloride repair and extension of parking garage in Kaltenkirchen, Segeberg district

Alhussain Yousef completed his Bachelor's degree in Civil Engineering with a specialization in Construction Operations and Management at Tishreen University in Syria. In 2018, he began his Master's studies in Structural Engineering at the Technical University of Dortmund. He wrote his Master's thesis under the supervision of Prof. Dr.-Ing. Panagiotis Spyridis at the Professorship of Fastenings Engineering, focusing on the modeling of power-actuated fasteners in steel fiber reinforced concrete.

After completing his Master's degree, he worked as a research associate at the Professorship of Fastenings Engineering, where he deepened his research in the areas of post-installed bonded anchors in normal concrete, power-actuated fasteners in concrete and fiber-reinforced concrete, as well as their interactions with cracks in concrete and their modeling using nonlinear finite element software.
