Dr. Alex Shenfield MEng, PhD, SMIEEE

Associate Professor in Machine Learning


Summary

I am currently an Associate Professor of Machine Learning at Sheffield Hallam University. I joined Sheffield Hallam University in November 2013 from Manchester Metropolitan University and am a Senior Member of the IEEE (SMIEEE) and a Fellow of the Higher Education Academy (FHEA). My main research interests are in the field of machine learning and particularly in its application to real-world problems in image processing and pattern recognition, healthcare, and Industry 4.0.

About

I am an active researcher with research interests focused primarily in the field of machine learning and its application to real-world problems in image processing and pattern recognition, healthcare, and Industry 4.0. I have published over thirty peer-reviewed journal and conference papers on the application of AI and ML to a variety of problems in engineering, security, and healthcare in a range of high-impact venues (with more than a dozen oral presentations at international conferences). According to Google Scholar, my publications have received over 400 citations and I have a current H-Index of 10. I am currently principal investigator / co-investigator on five successfully funded external research and development projects investigating the application of ML techniques and software engineering principles to a variety of problem domains, with a total value to Sheffield Hallam University of over £750,000. As well as this, I have been principal investigator / co-investigator on several recently completed externally funded research and innovation projects (including grants from Innovate UK and MRC) and several smaller grants (including support from Google and nVidia). I was also the organiser of an invited special session at the 2017 IEEE International Conference on Computational Intelligence in Bioinformatics and Computational Biology in Manchester on the use of Machine Learning in Medical Diagnosis and Prognosis.

I am currently principal investigator or co-investigator on five successful externally funded research and development projects investigating the application of AI techniques and software engineering principles to a variety of problem domains, with a total value to Sheffield Hallam University of over £750,000. These include: The 24-month BBSRC funded "Reinventing Rice Milling for the Digital Era" project as Co-I with a total value of c. £1.07M (of which £426,000 is allocated to SHU). I am responsible for the development of novel AI techniques for computer vision based QA and machine optimisation in Industry 4.0. An Innovate UK funded KTP with ACS Stainless Steel as PI investigating the application of modern software engineering techniques to Design and Manufacturing Management (DMM) systems with a total project value of £220,000. A GrowMedTech Proof-of-Feasibility project (as Co-I) investigating the application of AI in a stroke risk monitoring service with a total project value of c. £29,000. I developed the models and algorithms underpinning the AI part of this project. A GrowMedTech Proof-of-Market project as PI investigating the application of AI assisted computer vision techniques in the development of a digital pathology platform with a total value of c. £5,000. I have also been principal investigator / co-investigator on several recently completed research and knowledge exchange projects including: As Co-I on the 12-month European Regional Development Fund (ERDF) funded project with British Online Archives investigating "Machine Learning in Linguistic Analysis for Historical Archives" (total value c. £90,000). Completed March 2020. As Co-I on the Medical Research Council (MRC) funded "AFRICAA (Automatic Face Recognition in Critical CAre)" project with North Middlesex University Hospital (total value c. £60,000). Completed January 2020. As PI for a European Regional Development Fund (ERDF) funded Sheffield Innovation Programme project with CIT Digital to investigate the application of deep learning algorithms in automated image tagging (project value £15,000). This led to two (unsuccessful) Innovate UK grant applications which both scored 70%. SIP project completed November 2017. As PI for a consultancy project with Proctor and Gamble investigating the use of embedded systems and miniaturisation for shaving augmentation (value c. £8,000). Completed March 2017. As PI for an Innovate UK funded KTP with Thetford Ltd. investigating the development of novel cooking appliances (and their embedded control systems) for use in the recreational vehicle and leisure industry (project value c. £132,000). Completed November 2016.
