Research and Scholarship

Dr. Quiel’s research focuses on structural resistance to extreme loads, particularly fire, blast, and progressive collapse. He has experience in the analysis and design of both steel and concrete structures and has worked on projects related to building frames, protective façade systems, and bridges. His research has both computational and experimental aspects and is focused on the development of improved design standards for structural resistance to extreme loads. His work has been published in both domestic and international journals and has been presented at conferences in the U.S., Canada, Europe, and Asia.

Before coming to Lehigh, Dr. Quiel worked professionally at Hinman Consulting Engineers in Washington, D.C. where he performed analysis and design of structures to resist extreme loads. During his four years in practice, he was involved in the design and analysis of various structural systems to resist the effects of blast, fire, and progressive collapse. Since arriving at Lehigh, he has served as a technical advisory consultant to multiple major construction projects.

Before entering professional practice, Dr. Quiel completed his doctorate in structural engineering at Princeton University on a Department of Homeland Security Graduate Fellowship. During his graduate study, he was awarded the Wu Prize for Excellence by the Princeton Engineering Office of Graduate Affairs in recognition of his dissertation research on the response of steel frames to fire. As part of his DHS fellowship, he spent two months at the Building and Fire Research Laboratory (BFRL) at the National Institute of Standards and Technology (NIST) and collaborated on a study of the role of fire in the collapse mechanism of the World Trade Center’s Twin Towers.

Teaching and Service

Dr. Quiel will be teaching CEE 290, CEE Design Project: Civil Engineering Design in spring 2014. While at Princeton, he contributed to courses on tall building design, prestressed concrete, and the undergraduate introduction to engineering.

Dr. Quiel has been a member of the ASCE Fire Protection Committee since October 2011. He is a member of the committee’s control group and has contributed to the committee’s development of an appendix to ASCE 7 for structural-fire loading.

Dr. Quiel is a technical reviewer for several engineering journals, including the Journal of Structural Engineering (ASCE) and Engineering Structures (Elsevier). He is a licensed professional engineer in the Commonwealth of Virginia and is a member of the Chi Epsilon and Tau Beta Pi engineering honor societies.
