Professor Sandy Cochran
Summary
Sandy Cochran, Professor of Biophysical Science and Engineering, holds a BSc in electronics and computing, an MBA, and a PhD from the University of Strathclyde. He worked in the Centre for Ultrasonic Engineering, Department of Electronics and Electrical Engineering (1986 – 1989, 1996 – 2000), and in the Superconducting Devices Research Group, Department of Physics (1990 – 1995), at the University of Strathclyde before moving to the University of the West of Scotland (2000 – 2007) to set up a group working on Microscale Sensors with colleagues. He moved to IMSaT, University of Dundee, in 2007, where he is now Deputy Director and Team Leader in Ultrasound.

Prof. Cochran’s main research interests are focused on devices for ultrasound in medicine and life scientists. The ultrasound lab in IMSaT is the only one in the UK dedicated to medical ultrasound device design, fabrication and testing, and one of only a handful like it in the world. Topics of particular interest at present are new piezoelectric materials and better utilisation of existing materials, miniature devices for new applications and ultrahigh resolution imaging, focused ultrasound surgery and ultrasound-targeted drug delivery, and sonotweezer devices for manipulation of cells and particles.
Publication Summary
More than 200 publications in total: authorship of 3 book chapters; more than 50 refereed journal papers; more than 70 papers in conference proceedings; and around 100 conference presentations.
Research Funding Summary
As an independent research fellow/academic, Prof. Cochran has attracted more than £9M of research funding, £3.5M as Principal Investigator, principally in the area of piezoelectric devices for applications of ultrasound in medicine and life sciences.
