SANTA ROSA, CA, April 01, 2025 /24-7PressRelease/ -- E. Leroy Tolles has been selected for inclusion in Marquis Who's Who. As in all Marquis Who's Who biographical volumes, individuals profiled are selected on the basis of current reference value. Factors such as position, noteworthy accomplishments, visibility, and prominence in a field are all taken into account during the selection process.

Dr. Tolles is a distinguished figure in the field of structural engineering, with a career spanning over 45 years. As the principal consultant at ELT & Associates since 1985, he has dedicated his expertise to design, research and the investigation of buildings, particularly focusing on seismic design and retrofitting of adobe and other earthen structures. His work has significantly contributed to understanding how earthen buildings behave during earthquakes and the methods, both simple and advanced, that can be utilized to enhance their safety. His commitment to his profession is evident in his day-to-day activities, where he balances research, design work and field inspections.

Dr. Tolles' academic journey began with a B.S. in 1977, a master's degree in 1982, and a Doctor of Philosophy in structural engineering from Stanford University in 1989. His doctoral thesis, "Seismic Studies on Small-Scale Models of Adobe Houses," was published at the John A. Blume Earthquake Engineering Center and remains a cornerstone of his contributions to the field. He is also a registered California professional civil engineer, which underscores his technical proficiency and dedication to maintaining high professional standards.

There are many areas of the world where an individual earthquake has resulted in the deaths of thousands or tens of thousands of the occupants of adobe buildings. This was the primary motivation behind Dr. Tolles' interest in improving the seismic safety of adobe buildings. In developing countries, adobe houses are primarily lower-income; therefore, the options for seismic design must be low-cost. His work on historic buildings began in 1990 with this work with the Getty Conservation Institute. For historic buildings, the goal is to have minimal impact on the historic fabric. The seismic design of adobe buildings, whether for low-income housing or historic buildings, must be effective, low-cost and have a minor impact on the building itself.

His work with the Getty Conservation Institute marked a significant milestone in his career. This project was called the Getty Seismic Adobe Project (GSAP) starting in 1990 with the final publication in 2002. The GSAP program was unique with its combination of design, research and field work overseen by a diverse advisory committee. As part of his work as the principal investigator, he co-authored several influential publications on seismic retrofitting and stabilization of historic adobe structures. These works include "Survey of Damage to Historic Adobe Buildings After the January 1994 Northridge Earthquake" and "Planning and Engineering Guidelines for the Seismic Retrofitting of Historic Adobe Structures," both published by the Getty Conservation Institute. He has also organized and presented several workshops, including the Workshop on the Seismic Retrofit of Adobe Buildings at the J. Paul Getty Museum in California. His research on testing the seismic performance of adobe buildings was conducted at Stanford University, University of California, Berkeley, and the IZIIS Institute in Skopje, Macedonia. He has presented his findings at the Ninth World Conference on Earthquake Engineering, the 1990 and 1993 Conferences on Preservation of Earthen Buildings, along with many other presentations including one in Tangshan, China – the location of the worst earthquake disaster in human history. Throughout his career, Dr. Tolles has been associated with prestigious organizations such as the Structural Engineers Association of California and the Earthquake Engineering Research Institute.

In addition to his professional achievements, Dr. Tolles has been actively involved in civic activities, serving on the school board in Piedmont, California, for eight years. His commitment to community service reflects his belief in encouraging extracurricular engagement among individuals. This dedication extends to his personal life, where he draws inspiration from his parents—his father being listed in Who's Who in 1986 and his mother continuing her successful career as a children's book author at 103 years old.

Dr. Tolles attributes his success to his ability to dedicate himself fully to each task. His college experience on the wrestling team played a crucial role in helping him complete his doctoral studies, as it required immense commitment, focus and dedication similar to the demands of a successful wrestling career. He also feels driven by a desire to make positive social contributions to humanity, which is a significant aspect of both his personal and professional lives.

Outside of his career, Dr. Tolles enjoys spending time with his family, hiking, gardening, farming and playing music. Looking ahead, he remains passionate about contributing to society through his work and aims to develop a practical design manual for adobe buildings that will serve as a valuable resource for design engineers. This goal aligns with his lifelong pursuit of making meaningful social contributions through education and engineering innovations.
