Dr. Erdem specializes in structural analysis and mechanics of structures. He has experience in behavior of reinforced concrete structures and has investigated the repair/strengthening techniques for masonry infilled structures. He has conducted laboratory testing to determine the capacity of reinforced concrete frames strengthened with either concrete infill or carbon fiber reinforced polymer (CFRP) applied masonry infill. Dr. Erdem visited an earthquake-hit region (Bingol/ Turkey) in May 2003 and collected data from damaged or collapsed buildings (structural characteristics of the structure, nature and extent of the damage) to assist in a damage assessment project. He assisted in evaluation of the documents and reports on numerous collapsed structures due to 1999 Marmara Earthquake. He is also experienced in finite element modeling and stress analysis of complex structural systems.
Prior to joining Exponent, Dr. Erdem was a research assistant at Cornell University, where he conducted nondestructive testing (impact echo) on graphite rods and developed a new finite element of the human thoracolumbar spine. He has also lectured a graduate level course on concrete structures for two semesters.
