Dr. Bart F. Zalewski is a NASA contractor, a senior mechanical engineer at ZIN Technologies, Inc, an inventor, and an entrepreneur who also serves on the Quality and Robust Design Committee of SAE. He has received a B.S. and M.S. degrees with a focus in structural engineering in May 2005 from Case Western Reserve University (CWRU). His M.S. thesis dealt with dynamic load effects on bridge-mounted structures. He received his Ph.D. from Case Western Reserve University in August 2008 with a focus in computational mechanics. His Ph.D. dissertation dealt with discretization errors in Boundary Element Method (BEM). He is also an alumnus of the Center for Reliable Engineering Computing (REC). From 2010 to 2013 he served as an Adjunct Assistant Professor at the Department of Civil and Environmental Engineering at CWRU. In 2013 he co-founded ZalNear Space, LLC to develop new technologies for near space flights.

Dr. Zalewski’s interests include computational mechanics, finite element methods, boundary element methods, mesh free methods, finite difference methods, composite structures, near space technology, acoustic mediation techniques, separation analysis, interval analysis, and fuzzy analysis.

Dr. Zalewski has developed the first method to provide guaranteed bounds on the real discretization errors, not on the estimates, using a set weak form, or possibilistic weak form. He is also one of the pioneers of the interval boundary element method (IBEM) and fuzzy boundary element method (FBEM). Dr. Zalewski developed interval kernel splitting technique (IKST), which encloses the true solution to Fredholm equations of the first and second kind. He has received numerous awards and received recognition from NASA for his support and contribution to the advanced composites technology (ACT) team and Ares V engineering team. He is an author of several peer reviewed journals and conference publications.

Currently, Dr. Zalewski is working on NASA's SLS project which will allow for exploration into deep space. His work includes composite structure analysis and optimization of the payload fairing, its separation, and acoustic attenuation. He invented Stitched Bonded Joints (SBJ's) for cured composite panels, Reconfigurable Structural Joints, Deployable Structural Joints, Tuned Chamber Core (TCC) acoustic treatment, and Chamber Attenuator for Low Frequencies (CALF).

Dr. Zalewski is researching techniques for solving improper interval linear system of equations and providing exact bounds for the inner enclosure in a weak sense. He is also researching the usage of improper intervals for providing inner bounds on the local discretization error for boundary element methods. Other research topics include material uncertainty for plane strain problems and thermal conduction in boundary element method, local discretization error enclosure for finite element method, and local discretization error for a residual interval boundary element method (RIBEM).

Dr. Zalewski is researching and developing new technologies for near space vehicles.
