Technical Assistant Staff, Processing & Characterization

Chemical engineer from Puerto Rico working on characterization of process and materials for additive manufacturing at ORNL.  Working on a masters in mechanical engineering at the University of Tennessee.  President of a national microscopy society for students in order to advance characterization nationwide and assist future microscopists to reach their career goals. 

I have worked 12+ years at ORNL in characterization of materials for an array of purposes.  Some of the techniques utilized for this are: microscopy (LM and EM), mechanical testing, resonant ultra-spectroscopy, thermo-mechanical analysis, dynamic mechanical analysis, indentation, x-ray computed tomography, etc.
