I am a graduate research assistant in the Mechanical Engineering Dept. at The University of Texas at Austin , doing research on nondestructive evaluation of Homopolar Pulse Welding (HPW) of HSLA linepipe for deepwater J-LAY applications.. I am pursuing my MSE in Mechanical Engineering.


I received a B.S. in Mechanical Engineering concentrating in mechanical systems and design from The University of Texas at Austin in August of 1993.

Research Interests

My current research interests include nondestructive evaluation (NDE) of Homopolar Pulse Welding (HPW) of HSLA linepipe. This new welding process is being developed for J-LAY pipeline applications for deepwater pipelines. Research includes characterizing defect types present in HPW welds and selecting an appropriate NDE method for detecting such flaws. HPW flaw occur along the welding interface and may result from variability in end preparations. End preparation also effects the contact resistance which contributes to the resistive heating at the interface. My thesis will evaluate the contribution of the contact resistance heating to the total heating in a HPW weld.
