Investigating the measurement of pedestrian reassurance
Following the completion of my bachelor’s degree in Architectural Engineering, I continued my education at master’s level in Construction and Project Management at Shahid Beheshti University, Iran, where I worked on developing Sustainability Assessment Tools in The Built Environment using Maturity Models as my thesis project. After working in the built environment industry as a researcher for two years and also teaching as a lecturer for four years, I joined the University of Sheffield to further develop my knowledge in Sustainability in the Built environment, as part of the MSc Sustainable Architecture Studies programme.
As a PhD student in the Lighting Research Group, my research involves investigating how road lighting contributes to pedestrian’s feeling of safety (reassurance) when walking alone after dark. The aim of this research is to investigate different approaches in determining optimal values for various lighting characteristics (eg illuminance, spectral power distribution and spatial distribution) with regards to pedestrian reassurance, whilst accounting for other lighting needs of all road users (ie pedestrians, cyclists and drivers). By defining these values this research will help enhance perceived safety and lower fear of crime, leading to encouragement of walking.
Does road lighting enhance pedestrian alertness?
I hold a bachelor’s degree in Architectural Engineering from Al Albayt University, Jordan. My graduation project was An education city for developing creative thinking skills. I tried to link light and perception during the concept level, I studied how the speed of things relative to the speed of light affects our perception of them and the things which we can call reality. In 2017, I received my master’s degree from The University of Jordan. My thesis was about how lighting conditions affect emotions and perception: my most important finding was that light influences the recipient's feelings and emotions.
For the past seven years I was a lecturer in the Faculty of Engineering, AL Albayt University, Jordan. I taught illumination and acoustics in the architecture design studio. As a volunteer I worked at the We Are Jordan Youth Commission. In my role as head of the Committee on Educational Development I led the development of plans designed to increasing the environmental quality of neighbourhoods in Jordan.
As an early stage researcher in the LightCAP project, my PhD research is about Lighting at un-signalled (zebra) pedestrian crossings. I will investigate optimal lighting characteristics, including illuminance, spectrum, and uniformity. The research will include making pedestrians more alert to potential hazards and could enhance visibility and the visual perception to detect dangerous objects.
Investigating the use of odds ratios as a tool for research of cycling and lighting
I joined the SSoA Lighting research group as a PhD student in 2020. The focus of my research is the relationship between lighting and the built environment and how that relationship could influence the safety of pedestrians and cyclists. My aim with this research is to be able to recommend a set of design guidelines that may promote more walking and cycling by increasing the feeling of reassurance.
Prior to starting my PhD I worked as an Architect in the healthcare field and in 2017 I joined the Faculty of Architecture and Planning in King Abdulaziz University (Jeddah, Saudi Arabia), as a lecturer. My qualifications include a BArch from King Abdulaziz University (2011) and a MEng in Facade Design and Construction from the Technische Hochschule Ostwesfalen-Lippe University of Applied Sciences in Detmold, Germany (2014).

Driving, lighting and cognitive load
I was awarded my bachelor's degree in civil and environmental engineering from University of Isfahan, Iran. I then studied for a master’s degree in sustainable building information management at Jonkoping University, Sweden. My master thesis, and subsequent post-doc post at Jonkoping, concentrated on optimised light environments through smart systems in residential buildings, covering both the needs of occupant well-being and the electric lighting energy.
My PhD topic is lighting for driving and hazard detection. The project will investigate the influence of lighting characteristics such as light level and light spectrum on the visibility and conspicuity of hazards, and the driver’s alertness to potential hazards.
As one of the 15 researchers in the LightCAP team, I am devoting my PhD research to become an expert able to deliver on the promise of truly intelligent, human centric lighting. My aim as a PhD student at the University of Sheffield concerns how lighting conditions affect a driver's ability to detect and identify hazards. Exposure to light affects hormone concentration, brain activity patterns, core body temperature, pupil size, feelings of sleepiness, alertness, and even task performance. This study aims to consider the manipulation of non-image-forming-system and carefully evaluate its potentials for the driver's alertness and performance. Since such manipulation has a direct impact on human circadian rhythm and its phase shifting, all aspects need to be carefully investigated to predict unwanted side-effects.
Hazard detection when driving
He is now an ESRC funded 1+3 PhD student. This specific type of PhD consists of a MA year in Social Research followed by a three year PhD situated between the Schools of Architecture and Psychology.
In 2015 Scott gained a first class BSc degree in Psychology. The research at this level involved investigating how lighting conditions and spatial frequency influence facial identification to explain why people see ghosts. Such psychophysical phenomena greatly interests Scott, although he is interested in research that has clear practical outcomes. This is what drives his passion for academia, and what drove him into research with a more practical focus.
Indeed, drive is the appropriate word to use regarding not only Scott’s subsequent research experience following his undergraduate degree, but also his PhD project. He was employed as a Research Assistant at the University of Sheffield in 2016. The research involved investigating the influence of road lighting on driving performance, both in terms of adaptation to light and dark and how fog interacts with light to impact driving performance. His PhD project takes inspiration from the research conducted in the outlined Research Assistant post, in which different types of distraction on the road and how they impact driving performance will be investigated. This primarily includes elements of lighting and sound.
Using lighting to help pedestrians be safe and feel safe
My goal is to become an architect. I first studied at the Engineering College in Saudi Arabia where I received a bachelor degree in Islamic Architectural Engineering (2009). After graduation I was accepted as an assistant lecturer at Al-Baha University in Saudi Arabia. From 2010–2012 I improved my English language skills studying at the University of Oregon in the USA. In 2014 I was awarded a Master’s degree in Interior Design from Lawrence Technological University, USA. I went back to Saudi Arabia for two years practising my job as a lecturer in Al-Baha University. Finally, January 2018 I started my PhD research in the UK at the University of Sheffield, School of Architecture.
A main goal of street lighting is making pedestrians safe and feel safe after dark. The visibility of a face changes with the fall of light and hence the person’s location relative to lamp posts – they may be front lit, in which case the face is visible, or backlit, in which case the face is not clearly visible. The research experiment has two test procedures category rating and paired comparisons. These procedures ensure believable results, and to compare evaluations of safety when looking at other pedestrians in a night-time street scene. The experiment’s results will be analysed using statistical techniques to determine the importance of differences – which acted situations are considered to be more unsafe than others?

Designing home windows to provide Useful Daylight Illuminance for health and wellbeing, concurrently, and maintaining privacy for Libyan women
I graduated as a Libyan architect in 1997 from in the Department of Architecture at the College of Architecture and Arts in Omar Al-Mukhtar University, Libya. After I had graduated, I started working as an architectural designer in a consultant office in Libya until I engaged in master’s level study in the department of Architecture at Istanbul Kültür University in Turkey in 2007. When I came back to Libya, I taught in my College from 2007 to 2012 when I travelled to the UK. Recently, I have started my PhD study in the School of Architecture at Sheffield University. My studying purpose has stemmed from my desire to design distinctive windows that provide suitable health daylight and at the same time maintain the visual privacy of Libyan women.
In the Libyan context, privacy is the most crucial issue in the residential environment. Libyan women spent most of their time at homes because of their daily duties. Findings indicate that social-culture, aspects and religion requirements influence the visual privacy of Libyan women in their houses. A desire to achieve privacy may affect negatively on the efficacy of natural light inside houses that needed for women health and wellbeing. This research study seeks to investigate how to maintain the useful daylight Illuminance that can be provided, whilst maintaining the acceptable visual privacy of Libyan women inside their homes during the daytime. Therefore, the research aims to design windows for Libyan residential homes to achieve the requirements of privacy for Libyan women on one side and their health and wellbeing on the other side.
