Young HKBU mathematics scholar wins international recognition


The distinguished contribution made by Dr Liu Hongyu (right) to inverse problems is recognised at the international level.

Dr Liu Hongyu, Associate Professor of the Department of Mathematics of HKBU, received the Calderon Prize at the 9th Applied Inverse Problems (AIP) Conference held in Hangzhou, China. Widely recognised as the highest award in the field of inverse problems, the prize is presented to researchers under the age of 40 who have made distinguished contributions in this field. Dr Liu and a scholar from the US were selected for the prize this year.

Dr Liu was honoured to receive the prestigious award in recognition of his mathematical research related to inverse problems. He said, “The HKBU Department of Mathematics has provided an excellent environment for innovative and original research development. Our group at HKBU has conducted systematic studies on several inverse problems including inverse scattering, wave imaging and metamaterial cloaking. We work on both the theoretical and computational aspects of those inverse problems and consider their applications in medical imaging and artificial intelligence technology.”

Inverse problems arise from the need to interpret indirect measurements. They lie at the core of many areas of science and technology such as medical imaging, non-destructive testing, underground prospecting, astronomical imaging, imaging processing and data mining. The AIP Conference is the premier scientific meeting for this field and is organised by the Inverse Problems International Association (IPIA) every two years. The IPIA presents the Calderon Prize every two years at the AIP Conference.
