Samuel Ariaratnam is a nationally recognized expert in trenchless technology, which uses a variety of surface-monitored, underground excavation tools to replace and install utility lines for oil, natural gas, water, sewer, electrical, and telecommunications and fiber optics without disrupting neighborhoods, roadways, railways, riverbeds and ecologically sensitive areas. Ariaratnam, a registered professional engineer in Arizona and Ontario, Canada, served on the North American Society for Trenchless Technology Board of Directors from 2001-2006. Currently, he serves as the immediate past chairman of the International Society for Trenchless Technology, and recently was appointed to the Executive Committee of the American Society of Civil Engineers (ASCE) Pipelines Division. He is a co-author of the "Horizontal Directional Drilling Good Practices Guidelines" and the "Pipe Bursting Good Practices." Ariaratnam is a professor and Beavers-Ames Chair in Heavy Construction in the ASU’s School of Sustainable Engineering and the Built Environment. He also serves as Chair of the Construction Engineering Program. He co-authored the Maricopa Association of Government’s public works specifications for installing underground utilities in 2016.

Alessandro Palermo is an expert in the seismically safe design of buildings and bridges, with an additional focus on sustainability. He holds twos patents in mass timber construction, one of which is consider the basis for the advancement of seismically resilient technologies for timber construction and adopted in several buildings around the world.
Palermo has expertise in material degradation and potential mitigation strategies. For example, one of his recent projects aims to improve the lifespan of bridges by using innovative materials and by understanding the impact of corrosion on a bridge’s seismic performance. He also has done work on using waste materials, such as tires and glass, to improve the seismic performance of concrete structures.  
Palermo expertise branches out to digital construction as well. He is currently working on an extensive testing program to quantify the performance of 3D Printed concrete houses during earthquakes, the Achilles’ heel of the technology.
