Brian’s current research focus is the development of a database of microstructural features and mechanical properties of the beta titanium alloy Ti-5553 (Ti-5Al 5Mo-5V-3Cr). To do this, Brian will use the ETMT (electrothermal mechanical tester) and Gleeble to perform a variety of heat treatments and then mechanically test the samples. Stereology will be performed on the samples to create a database of microstructural and mechanical property information. The database will then be used to train a Bayesian neural network which will allow him to understand how the microstructural features and composition affect the mechanical properties of the alloy. Brian will also be using the FIB and TEM to understand the nucleation of alpha in this alloy.

Brian attended the University of Cincinnati his freshman year majoring in Electrical Engineering. He then transferred to the Ohio State University where he graduated with a BS in Materials Science and Engineering in the spring of 2005.

In his spare time, Brian enjoys going to Ohio State Buckeyes and Cincinnati Reds games with his girlfriend Lindsay. He also keeps busy during the summer and fall playing in softball and sand volleyball leagues with his friends. Brian also enjoys golfing and rafting the Gauley in West Virginia.
