Prof Dr Ingrid Daubechies, internationally award-winning mathematician, is this year's keynote speaker at the Weierstrass Lecture at Paderborn University. On Friday, 11 July, the scientist will give an insight into current topics of her research. Anyone interested can attend the event; prior registration is not necessary. The lecture will be held in English.
Daubechies' research focuses primarily on mathematical aspects of time-frequency analysis. She became known through the discovery of so-called wavelets, which are used in image compression. A wavelet is a mathematical tool that can be used to remove unnecessary information from large image files. Daubechies has thus revolutionised the use of JPGs and other digital image formats. Her theory has also led to the development of image filtering methods used in medical imaging devices and wireless communications. Daubechies' more recent work focuses on the development of analytical and geometric tools for comparing surfaces, which plays an important role in video animation and medical applications, for example.
Daubechies has been a professor at Duke University in Durham, USA, since 2011. Prior to this, she worked at Princeton University, also in the USA, in various scientific roles. She is a member of the US National Academy of Sciences and has received numerous honours: Last year, she received the prestigious "Bakerian Medal and Lecture" from the Royal Society, UK. In 2023, she was awarded the Wolf Prize in Mathematics. In 2019, she was awarded an honorary doctorate from Harvard University, Cambridge, USA, and the L'Oréal-UNESCO for Women in Science Award. She received the Benjamin Franklin Medal in Electrical Engineering from The Franklin Institute, Philadelphia, USA, in 2011.
The lecture continues a Paderborn lecture series that has also attracted a great deal of international attention. The lecturers are selected by an independent jury, which currently includes Professors Martin Kolb (Paderborn), Gérard Laumon (Paris) and David Vogan (Cambridge, USA). The format, which has been held annually since 2011, consists of a keynote speech and an introductory historical lecture. The series of events is named after Karl Weierstrass (1815-1897), who graduated from the Theodorianum grammar school in Paderborn in 1834 as "primus omnium", i.e. the best graduate of the school. Weierstrass was one of the most important mathematicians of the 19th century and is considered the founder of modern analysis, among other things.
