Biography

Sidahmed is assistant professor in biomedical imaging and sensing and a member of Electric and Electronic Engineering Department since Sept. 2022. Before this role, he was an independent Nottingham Research Fellow between 2019 and 2022. He obtained his PhD in Electrical and Electronic Engineering in 2016 from the University of Nottingham. In 2015, he was awarded a prestigious two-year EPSRC Doctoral Prize Fellowship at the Faculty of Engineering, the University of Nottingham (UoN) to test new concepts in impedance microscopy, a novel technology for label-free characterisation of biological samples. In 2018, he moved to the School of Pharmacy as a postdoctoral research fellow to investigate novel strategies for optical imaging of nanoelectrochemical reactions for bioelectronic and electroceutical applications. In 2019, he returned to the Faculty of Engineering after being awarded a prestigious Nottingham Research Fellowship to set up and lead cutting-edge research in 'voltage plasmonics'. One of the ambitions of this new field is to develop a new generation of impedance micro-spectroscopy technology. This new tool will allow us to understand how living systems generate and conduct electrical signals with novel applications in neuroscience and cardiac science.

Recent Publications

Past Research

  • Plasmonic imaging of nanosystems for Electroceuticals applications (2018 - 2019)
  • EPSRC Doctoral Prize Fellowship (2016-2018): The long-term goal of this fellowship is developing a novel high-resolution impedance micro-spectroscopy technique that is capable of ''imaging'' the electrical properties of biological samples in a similar way to microscopes that image the optical properties. Imaging these properties promises rich information on cell structure and function with applications in cell biology and drug testing. This project is directed at developing bespoke instruments for accurate measurements of impedance with sub-micron resolution.

  • Smart pocket sensor for rapid diagnosis of urinary tract infections (UTIs) This project aims to develop a compact and automated instrument for culture-free detection of bacteria in urine. The project addresses the need for developing tools to enable rapid diagnosis of infections. The delay in diagnosis leads to prescription of empirical broad spectrum antibiotics that contributes to the growing problem of antimicrobial resistance.

  • Sensing voltage dynamics using plasmonic sensors (2012-2015): This project focused on designing and characterising highly-sensitive plasmonic sensors applied to label-free detection of voltage at the metal-electrolyte interface. These sensors enabled us to detect voltage pulses as small as 10mV on a millisecond timescale and with no fluorescent labels. The findings of this project pave the way for using this technology to record the electrical activity of excitable cells.
  • Bio-photonics for surgical navigation (May 2013 - Sep 2013): Industrial placement at Etalon Research Ltd (Nottingham, UK)
