Joshua holds a master’s degree in Physics from the University of Sheffield. He later transitioned into Materials Science, undertaking a PhD at the same institution. His doctoral research, completed within the IDEAs group under the supervision of Prof. Katerina Christofidou, focused on materials informatics to accelerate the development of hard metals. During his PhD, Joshua also collaborated with the AIRE team in the Computer Science Department, contributing to an interdisciplinary project at the intersection of materials science and data-driven methodologies.

Currently, Joshua continues his work with the IDEAs group as a Postdoctoral Research Associate. His research now focuses on powder feedstock recycling and reconditioning for laser powder bed fusion additive manufacturing processes. This work aims to enhance the sustainability of additive manufacturing by reducing its environmental footprint.

Sebastian holds a PhD degree in Materials Science and Engineering from AGH University of Krakow. His PhD thesis under supervision of Professor Adam Kruk was done in collaboration with Pratt & Whitney, US on the microstructure evolution of a novel superalloy at high temperatures. After his graduation, he stay at AGH as an Adjunct. In 2022 he joined Professor Mitra Taheri’s group as a postdoctoral researcher, where he worked on high-throughput experiments, laser directed energy deposition and refractory high entropy. Later, he worked as a Research Scientist combining his research in Taheri’s group with additive manufacturing lab manager role at the Materials Characterization and Processing facility at JHU. 

In October of 2025, Sebastian joined the IDEAs group, where he will be working on additive manufacturing of tungsten and nickel-based superalloys. 

Outside of work, he enjoys sailing, travelling and sports. Sebastian used to train volleyball and American football, where he played as a running-back.
