Current staff


Prof. Dr. Michiel Postema

Prof. Postema holds an MSc (Utrecht) in geophysics and a Doctorate (Twente) in the physics of fluids. He was awarded an Emmy Noether research group at Ruhr-Universität Bochum and an EPSRC research fellowship at The University of Hull. He is appointed visiting Professor at the University of Orléans (2010), The University of Dundee (2012), Technion (2012), and full Professor of Experimental Acoustics at the University of Bergen (2010).
Prof. Postema has written 106 scientific publications on acoustics and cavitation, including 50 first-author papers and 6 co-authored textbooks. He is an Associate Editor of Applied Acoustics (Elsevier), Associate Editor of Ultrasonics (Elsevier), member of the editorial board of Bubble Science, Engineering and Technology (Maney), and board member of the International Congress on Ultrasonics (ICU).

Dr. Spiros Kotopoulis

Dr. Kotopoulis holds a BEng (Hons) and Ph.D from the University of Hull, in the United Kingdom. He was a awared a 3 year Research Fellowship from Helse Vest in 2013 to understand and tranlate sonoporation from the lab enviroment to the clinic.
Dr. Kotopoulis has 27 scientific publications on ultrasonics and transducers including 3 co-authored books.
Dr. Kotopoulis is a reviewer for several journals including Ultrasonics, Applied Acoustics, Molecular imaging and Biology and Review of Scientific Instruments.


PhD students
Michaela Chovancova

Michaela Chovancova was born in Nové Zámky, Slovakia in 1985. At the age of 22 she moved to Bratislava to study Chemistry and Biomedical Physics for her Bachelors degree, of which she successfully acquired in 2010. In 2010 she subsequently pursued a Masters degree in the same subject of which she successfully received in 2012. As of March 2013, Miss Chovancova is a PhD candidate at the Micro-acoustics Group at the Department of Engineering and Technology, University of Bergen under the supervision of Prof. Dr. Postema and Dr. Kotopoulis. Her chosen topic is simulation of custom microbubbles designed for sonoporation. Her target is to expand these models for drug loaded microbubbles in the presence of solid and flexible interfaces such as cell membranes.


Masters Students

Christofer Johansen

Kristoffer Johansen was born in Haugesund, Norway in 1991. He lived there until he was 19 years old then moved to Bergen to start a Bachelors degree in Physics (BSc) at the University of Bergen, of which he successfully acquired in 2013. Since then he has started towards his Masters Degree (MSc) specializing in physical acoustics at the University of Bergen. He is currently working on fabrication and characterization of anti-bubbles for targeted drug delivery. His work is both experimental and theoretical. In addition Mr. Johansen is also working on a project in collaboration with Bergen Kommunale Kraftselskap (BKK) where he was awarded 39 000 NOK to investigating if ultrasound can be used to filter water in hydroelectric power plants.

Torstein Yddal

Torstein was born in Breim, in Norway in 1990. He finished his Bachelors degree in physics (BSc) at the University of Bergen in 2013. Currently he is working on his masters project about the design, development and fabrication of a multi-element dynamic focused ultrasonic probe for therapeutic and diagnostic uses. He is also hired by Haukeland University Hospital as a lab technician, where he has helped develop fully acoustically characterised tools for research on cancerous cells.
