As the Vice President of Laboratory Services at CTLGroup, Dr. Clark excels in materials science, new product design, and the research and analysis of building materials. He is additionally proficient in the application and use of transmission electron microscopy (TEM), scanning electron microscopy (SEM), optical microscopy, X-ray diffraction (XRD), and X-ray fluorescence (XRF). Dr. Clark is also one of CTLGroup’s lead principal investigators for countless construction litigation cases for various materials-associated and building component failures relating to construction defects. Dr. Clark has evaluated numerous construction defects involving failures of coatings including paint delamination (on metal or concrete), cementitious material finish coats, and elastomeric coatings on exterior building surfaces. Dr. Clark has years of experience with laboratory management and numerous materials science testing methods. Dr. Clark has worked with various governmental agencies including projects associated with the DOT, DOD, DOE, and NRC.
Prior to joining CTLGroup, Dr. Clark worked at a major testing and consulting firm where, among other roles, he served as Director of Construction Materials Services. There, he was involved in research and problem solving analyses for materials including ceramics, metals, minerals, and building products.
