My research interests are in chemical process safety and loss prevention.


Increased emphasis on the prevention of fires and explosions has led to a need for high-quality flammability data covering a wide range of compositions of fuel/oxygen/nitrogen. The purpose of this work is to obtain this data in a twenty-liter combustion sphere using a high-speed data acquisition system. The data will be used to verify and improve methods for predicting the flammability zone.

Other projects in flammability include: flashpoints of azeotropic mixtures, flammability behavior of aqueous solutions, auto-ignition temperature characterization and prediction, flame speed determination and models, and prediction of flammability parameters.


Past methods for characterizing reactivity have depended on temperature and pressure rates as a function of time. This research will apply the concept of thermodynamic availability to reduce the evaluation to a single function in time. Thermodynamic availability represents the maximum mechanical energy extractable from a substance - a parameter more indicative of damage effects than heats of reaction. This project will develop a method to determine thermodynamic availability using standard calorimeter data, and apply the method to the reactive analysis of a number of chemical systems.
