Dr Sherri Johnstone, PhD BSc CEng MIET MIEEE


Dr Sherri Johnstone is a Senior Lecturer in the Electronics Group in the School of Engineering. She has extensive research experience in measurement technologies for material property measurement.

Her current research interests include ultrasonic defect detection in solids and hot molten liquids and resonant ultrasonic spectroscopy for stress measurement.

She also researches in the area of electromagnetic measurement techniques. This includes the detection of residual stresses and phase transformation in steel, the development of a nano-Hall microscope and work involving a Scanning Kelvin nanoprobe.

Dr Johnstone has a strong interest in biological measurement techniques including the use of the Hall effect to measure ionic species in cells and measurement methodologies to understand the role of stretch receptors in the cardiovascular system. She is currently working on understanding and sytthetically recreating mechanisms in biological mechano-receptors.

She teaches Level 2 Analogue Electronics,Level 3 Electronic Circuits,Level 3 RF Engineering , Level 3 B.Eng CAD and Level 4 Applications and Design of ICs to Undergraduate students. She is currently the Level 4 tutor.
