Renate Tobies is a historian of mathematics and science at the Friedrich Schiller University in Jena (Germany). She had completed her academic degrees at the University of Leipzig. Throughout her career, she has held visiting professorships in Kaiserslautern, Braunschweig, Saarbrücken, Jena, Linz, and Graz, and an interim professor of the history of science and technology at the University of Stuttgart. In parallel, she served as the managing editor of NTM: Journal for the History of Science, Technology, and Medicine for twenty years. Her main research fields are the history of mathematics and its applications, and women in mathematics, science, and technology. She has published more than ten books and hundreds of articles. She is a full member of the Académie Internationale d'Histoire des Sciences (Paris) and a foreign member of the Agder Academy of Sciences and Letters (Kristiansand, Norway).

Many complex systems are a combination of deterministic and stochastic dynamics. In this talk I will first introduce typical deterministic chaotic behaviour and then focus on a classical system of randomly kicked rotors, and illustrate how correlated random kicks can elongate the prethermalisation stage (that is, a stage before the system energy diverges). This leads to many interesting ongoing and future works.

Photoacoustic imaging is a biomedical imaging technique that combines the power of both optics and acoustics to visualize structures within biological tissues. It involves the generation of acoustic waves through the absorption of pulsed laser light by tissue chromophores. Central to understanding this technology is grasping the mathematics behind it. In this talk we will see what are the principles behind photoacoustic imaging and what could be interesting mathematical research topics.
