Dr. Pauza specializes in materials and metallurgical engineering. He has specific experience in additive manufacturing (AM), computational materials science, and microstructure design/optimization. Dr. Pauza also has expertise in material evaluation and defect detection. Additionally, Dr. Pauza is experienced with a variety of materials characterization techniques including optical microscopy (OM), scanning electron microscopy (SEM), computed tomography (CT), x-ray diffraction (XRD), and electron backscatter diffraction (EBSD).

Dr. Pauza completed his Ph.D. at Carnegie Mellon University in 2021. His doctoral thesis work focused on the development of novel microstructure modeling techniques with the ultimate goal of controlling crystallographic texture during fabrication of laser powder bed fusion (LPBF) AM aerospace parts to improve fatigue and creep performance. While pursuing his Ph.D., Dr. Pauza also worked on projects investigating lifing performance of AM titanium (i.e., Ti64) parts, residual stress development during AM builds, optimization of post-print heat treatments for AM nickel-based superalloys (i.e., IN718), and in-situ x-ray imaging of the AM process. Dr. Pauza has also worked with various shape memory alloys including Nitinol, NiTiHf, and CuAlMn for both biomedical and aerospace applications.
