Clients seek out Peacock for his unique comfort level with highly technical, data-driven matters, including damages assessment. His successes span technical areas as varied as offshore rig construction (in an international arbitration); convoluted title histories for thousands of oil and gas leases (in an energy lawsuit in state court); the underpinnings of random number generation (in a series of patent cases); the sciences of toxicology, epidemiology, and environmental exposure (in state and federal toxic tort matters); and the use of environmental air modeling (in a variety of cases, including a plaintiffs’ class action for environmental property damage). Whether a favorable result depends upon the proper calculation of damages, or the application of advanced scientific theories, Trey is a quick study and an effective advocate.
