Dr. Berger received his BS in Civil (Structural) Engineering, a MS in Mechanical Engineering, and his PhD in Mechanical Engineering from the University of Maryland, College Park. Dr. Berger’s primary research interests are in the general area of the mechanical behavior and fracture of materials.
Specifically, he has been engaged in research concerning dynamic crack growth and crack arrest in brittle and ductile materials, analytical and computational tools for analysis of anisotropic solids, elastic wave-based models for the nondestructive evaluation of cylindrically anisotropic solids, discrete element models for fracture of rock, and numerical/experimental studies of deformation and fracture in functionally graded materials. Most recently, Dr. Berger has been involved with mechanics related issues in lithium ion batteries. Dr. Berger spent five years on the staff of the Fracture and Deformation Division of the National Institute of Standards and Technology (NIST), and has been at the Colorado School of Mines since 1994.
Dr. Berger has also held positions at the University of Notre Dame and the University of Alaska Anchorage and has held visiting positions in the Computing and Applied Mathematics section of Oak Ridge National Laboratory, the Department of Mathematics at the University of Manchester (U.K), the School of Engineering at the University of Seville (Spain), and in the Faculty of Engineering at the University of Brescia (Italy).
