We are pleased to announce that Cong Shi and Thi Lan Nhi Vu participated as invited speakers in mini-symposia at the SIAM Conference on Imaging Science (IS24) in Atlanta, Georgia, USA. Thi Lan Nhi Vu presented a talk entitled “High dynamic range image processing for medical ultrasound” and Cong Shi presented a talk entitled “Attenuation model for photoacoustic tomography with pressure and shear waves”. The conference, which is held every two years, brings together scientists from different disciplines such as mathematics, physics, engineering, statistics and data science, to discuss mathematical issues and other facets of imaging science, and to promote interdisciplinary exchange.
