William Brant is an Associate Professor at Uppsala University, Sweden and the Manager for Cathode Material Research and Development at Altris AB. He completed his PhD at The University of Sydney, Australia in 2014 on diffraction studies of lithium intercalation into defect perovskites, earning specialisation in inorganic material synthesis and characterisation. He then joined Prof. Kristina Edströms research group at Uppsala University in 2015. Within the following six years William was promoted to lecturer, then Associate Professor becoming a research leader on synthesis of cathode materials for lithium and sodium ion batteries with a key focus on Prussian blue analogues. This work has been intimately tied to the development of Altris which was co-founded in 2016. His work within both academic research and commercialisation activities was recognised in 2021 through the MIT Technology Review Innovators under 35 prize. In 2023 William took a leave of absence from the university to dedicate his efforts and expertise to material development within Altris.
