Dr. Behrens applies physics, surface chemistry, and engineering principles to manipulate material properties and solve technical challenges associated with product development, manufacturing, and product/process performance. He has been consulting on numerous projects centered on the failure and degradation of polymeric materials used for piping and liquid storage systems.
Dr. Behrens also has experience with the formulation and characterization of polymeric, particulate, or emulsified products serving a wide range of industrial purposes, including drug delivery, crop protection, human and animal nutrition, hair and skin care, cosmetics, and detergency. He has worked extensively on stability issues in colloidal dispersions, emulsions, foams, and protein solutions, and developed emulsion-based technologies for microencapsulation and microreactor fabrication. Drawing on substantial experience in both industrial and academic research, he can support clients in matters concerning product performance, intellectual property, and trade secrets.
Prior to joining Exponent, Dr. Behrens spent 13 years as an Associate Professor of Chemical Engineering at the Georgia Institute of Technology, where he made significant research contributions regarding the stabilization of protein solutions, emulsions, and non-aqueous dispersions, as well as the design of stimulus-responsive emulsions and microcapsules. He is further known for the discovery of capillary foams, a new class of foams with potential applications ranging from food and skin care to oil recovery and oil spill remediation. Before his academic appointment, Dr. Behrens worked for 5 years in the Polymer Research Division of BASF, where he headed a laboratory specialized on light scattering techniques and the advancement of formulation projects.
