- Profile
-
I received my MEng (hons) in Electronic Engineering from The University of Sheffield in 2009, and my PhD in Electronic Engineering from The University of Sheffield in 2014. My PhD involved the characterisation and application of various infrared photodetector technologies for use within non-contact temperature measurement instrumentation. After completing my PhD, I worked as a Knowledge Transfer Partnership (KTP) associate with AMETEK Land in Dronfield in partnership with The University of Sheffield for three years.
In April 2016, I returned to The University of Sheffield to work as a Postdoctoral Research Associate (PDRA) within the Sensor Systems Research Group in the Department of Electronic and Electrical Engineering. My research involved the development and application of novel forms of single-pixel based measurement instruments for a variety of academic and industrial measurements applications. From March 2021, I split this role whilst also working as a Teaching Associate within the department.
In February 2023, I was appointed to the position of Lecturer in Semiconductor Materials and Devices. I am developing non-contact measurement instrumentation for a range of new applications, including novel instrumentation for use with energy applications, with a focus upon nuclear and hydrogen energy. I am also developing instrumentation for use within the foundation industries, as well as enhancing the various research areas taking place elsewhere within the University.
In parallel, I am developing new forms of measurement instrumentation. This includes luminescence, fluorescence and phosphorescence measurement techniques, as well as highly sensitive optical instrumentation. I am also developing capabilities within printed electronic devices using Aerosol Jet Printing technology.
