Key Professional Experience

Dr. Nowatzki has over 45 years of cumulative experience as an engineering educator and consulting geotechnical engineer. He has performed and directed the analysis, design and field investigations for a variety of infrastructure facilities ranging from foundation systems for multi-story buildings to innovative designs for soil nail walls and MSE retaining structures. He has been a part of multi-disciplinary teams on major highway projects involving collapse-susceptible soils, earth fissures and other geologic hazards. He has performed forensic engineering as part of investigations for various geotechnical failures and developed remediation measures.

Dr. Nowatzki taught undergraduate and graduate-level courses at both the University of Arizona and the California Polytechnic State University in San Luis Obispo. Most of the courses at both institutions were practice oriented. While at the University of Arizona, Dr. Nowatzki co-authored an authoritative book on soil mechanics for off-road vehicle engineering that is still one of the standard references in that field. During his tenure there he directed 7 PhD dissertations and 29 MS theses in a wide variety of geotechnical engineering topics. Many of those research topics were the subject of some of the more than 35 papers he authored or co-authored that have appeared in either peer-reviewed journals or the proceedings of national or international conferences. Dr. Nowatzki is currently a Professor Emeritus of the University of Arizona. While at NCS Dr. Nowatzki has been active in developing guidelines for the implementation of Load and Resistance Factor Design (LRFD) methodology in geotechnical design that have served as the basis of policy statements for several transportation agencies. He has also co-taught courses on the topic for several agencies and for the Civil Engineering Department at the University of Arizona.
