Umeka is a Visiting Student in the NanoManufacturing Group supervised by Professor Michael de Volder at the Institute for Manufacturing, University of Cambridge.

She is currently enrolled in the Master's program at the School of Materials and Chemical Technology, where she conducts research in the Shimoyama Laboratory. She previously completed her undergraduate studies at Tokyo University of Science, graduating among the top five students in her department.

Her research focuses on electrochemical energy storage, with a particular emphasis on the performance evaluation of zinc-ion batteries incorporating electrolyte additives. During her time at IfM, she is investigating how these additives influence battery performance using advanced fabrication and characterisation techniques.

She is participating in this research exchange as part of a study abroad program supported by Institute of Science Tokyo, with funding provided by the Japan Student Services Organization (JASSO). Her academic interests include sustainable energy storage technologies and materials innovation for a decarbonized future.
