Research:

Brian Lejeune is a post-doctoral researcher and part-time lecturer in the Chemical Engineering department at Northeastern University in Boston, MA. Twin passions for engineering and the environment inspired Brian Lejeune to become a material scientist, and to undertake research into the development of new and inexpensive magnetic materials. He completed his Ph.D. in 2019 on “Composition-Lattice Interactions in Intermetallic Ferromagnetic Systems” quantifying the role of detailed chemistry on tuning the crystal structures and magnetic phase transitions in intermetallic ferromagnetic systems. During his Ph.D. Brian also spent 6 months at the Ames Laboratory as part of a prestigious Department of Energy (DOE) Science Graduate Student Research (SCGSR) fellowship performing single crystal growth and characterization of compositionally graded novel magnetic materials.

Brian’s research interests include tailoring functional magnetic materials and technologically relevant natural minerals by altering structure, composition, or through defect engineering. Brian’s expertise in materials synthesis, processing, and characterization has led to a diverse portfolio of research inquiries including: work on development of next-generation rare-earth-free permanent magnet materials, evaluating and enhancing the biocidal properties of Cu₂O for use in antimicrobial coatings, studying magnetic microwires for anti-counterfeit measures and authentication, use of magnetic microwires for directing neuron growth, and tailoring rare-earth free magnetic materials for room-temperature thermal management applications. Brian has authored 17 peer-reviewed publications and presented over 30 conference and invited talks. Brian is also the mineral curator for Lafayette College in Easton, PA and an avid mineral collector.
