Per Ask

---

The Division of Physiological Measurements Professor Per Ask has headed the division since 1999 but became full professor in 1989. His research profile is model driven flow estimation using ultrasound and bioacoustic techniques, mainly with cardiovascular applications. In 1983 he founded the Cardiovascular Dynamics Research Group together with professors Bengt Wranne (cardiology) and Dan Loyd (fluid dymanics). This group has reached international recognition and its research has proliferated. Today the group consists of a faculty of about 15 biomedical engineering and medical researchers at different departments and divisions with extensive international activities with e.g. a long lasting research cooperation with Stanford University including mutual exchange of researchers. The research on model driven flow estimation using ultrasound and bioacoustic techniques is combined with the biomedical optics research. The division is deeply involved in the Vinnova funded NIMED center of excellence for research cooperation with industry. We are part of the SSF funded (1998-2004) Cortech network of excellence for cardiovascular engineering research.

RESEARCH CONTRIBUTIONS
Author or co-author of about 250 publications, most of them in international journals or proceedings in the field of biomedical engineering.

I am heading a division for Physiological Measurements. The research has its focus in the cardiovascular area with competence on non-invasive diagnostic methods, modelling, ultrasound, bioacoustics and bio-optics. Together with professors Bengt Wranne(Cardiology/physiology) and Dan Loud (Fluid mechanics) founding member of the Cardiovascular Dynamics Research Group, an internationally recognized group.

I supervised for 8 PhD:s, (H Teriö -89, L Eidenvall -93, J Brandberg -00, T Ebbers -01 (was initially main supervisor, transferred to Matts Karlsson), R Andersson -02, P Hult -02 and I Fridolin -03 (was initially main supervisor, transferred to Matts Karlsson), Per Thunberg -04 (was initial main supervisor, transferred to Matts Karlsson and co-supervised for 4 PhD:s (A Spångberg -90, B Janerot Sjöberg -93, J Engvall -93, M Karlsson -95 ). I supervised 1 Licentiate (A Walker, -03) and cosubervised 1 (C Xiong -94).
