Dr. Bellamarie Ludwig received her B.S. in Chemistry and M.S., Ph.D. degrees in Materials Science and Engineering from the Pennsylvania State University. She joined the Applied Research Laboratory at PSU in 2009. Her M.S. research focused on the surface reactions of metallic aluminum and aluminum oxide powders with silanes utilizing in situ methods. During her Ph.D. work, she studied the bulk properties and flow behavior of metallic aluminum powders before and after surface modification. Her research interests include the surface functionalization of powdered materials, powder rheology, fluidization/flowability of surface treated powders, and materials characterization. She has also studied novel hydrogen-storage materials such as ammonia borane. Currently, she is working on photothermal curing of paints for navy applications and new data science projects with an emphasis on machine learning applications.
This faculty member is associated with the Penn State Intercollege Graduate Degree Program (IGDP) in Materials Science and Engineering (MatSE) where a multitude of perspectives and cross-disciplinary collaboration within research is highly valued. Graduate students in the IGDP in MatSE may work with faculty members from across Penn State.
