Profile
Safak joined Loughborough University (LU) London as a Senior Lecturer in October 2014, a year before the Loughborough University London campus was officially inaugurated. Including his academic studies, his research, innovation, and related enterprising career spans 25+ years, which is enriched by more than a decade-long Higher Education teaching experience to date.
From start, he was involved in taking a lead role in helping to create a brand-new research, teaching, and enterprise environment, namely the Institute for Digital Technologies (IDT). As a senior member of the faculty, he also actively contributed to the general setup across disciplines and institutes housed in a unique multi-disciplinary setting. He considers himself a founding member of the IDT in particular, with key involvements in the London School in general, both of which have successfully grown to become leading establishments in years.
Safak was the first Chief Programme Director of IDT for the initial years, who led the process of creating thirteen MSc programmes and their curriculum, including those needed revising and adapting based on the feedback received from the student cohort as well as by monitoring external competitors and evolving industry needs and interests. At the same time, he initiated the London School's master's level Dissertation programme development and its coordination, involving all faculty members, school-wide students, and related curriculum activities. Since then, he has co-led and managed this major activity with a colleague from another discipline at the School (2015-23).
For over two decades, Safak has engaged in both generation of research grant bids and conducting his research on those that align with his research expertise and interest areas. As such, he was the Technical Manager for several large-scale multi-national collaborative EC funded research projects that were coordinated by the team he has been a part of: CLOUDSCREENS (2014-18), ROMEO IP (2011-14), VISNET I & II NoEs (2003-09). Currently, he is the LU Principal Investigator (PI) for a five-university consortium Happier Feet research project funded by the EPSRC (2021-23) in digital health and care domain, while he was also the LU PI for the RegNet industry research project funded by the Innovate UK (2020-21), with a consortium of two universities and an SME industry partner to enable AI use in regulatory sectors. For further details on those, please see below.
Safak currently leads and teaches on the MSc modules that he has developed: Cloud Applications and Services; Digital Practices for Customer Engagement; and Digital Media Audiences and Markets taught across the IDT MSc programmes. The Cloud related module is also included in the MSc Data Science programme offered by the Computer Science department on the LU's East Midlands campus. His teaching portfolio also includes former MSc modules: Cloud Technologies and Systems; Introduction to Digital Technologies; and Mobile Networks and Clouds, as well as BSc modules: Advanced Digital Signal Processing and Media Processing.
He is the Programme Director for the following MSc programmes:
- MSc Digital Creative Media (10/2018 – Present)
- MSc Internet Technologies with Business Management (10/2016 – 09/2018)
- MSc Internet Media Clouds with Business (10/2014 – 09/2016)
- MSc Internet Technologies with Business (10/2014 – 09/2016)

Research
Current research and collaborations
"Human First" is Safak's motto for positioning his research from a general perspective, where he aspires to link his approaches and activities to meaningful causes with integrity and drive to conduct his research for the benefit and positive impact for human lives.
In pursuit of this, his research has flourished and evolved into three distinct yet inter-related strands over the years: 1) Digital media processing, immersive & interactive technologies, and media quality – for better experiences to all. 2) Applied machine learning & neural networks in digital signal processing, cybersecurity reinforcement, and health data analytics – for better communications, understanding, and protection. 3) Cybersecurity/privacy protection tools & solutions applied in digital health, care, and wellbeing – for better care and privacy preservation. As such, he has been involved in several research projects and collaborations, sampled as follows.

Areas of research expertise
- Digital media processing, immersive & interactive technologies, and media quality: Video compression, processing, communications & networking; 3D visual content quality metric building & evaluation to enhance quality of user experience; content adaptation for the needs of the prevailing context (user, environment, network, signal, device related); advanced techniques such as immersive media systems.
- Applied machine learning & neural networks in digital signal processing, cybersecurity reinforcement, and health data analytics: Deep neural networks (e.g., Generative Adversarial Networks: GANs), and/or other machine learning techniques are applied to predicting and recovering lost speech frames via intelligent voice/audio signal inpainting (where possible) over lossy communication lines or storage using historical data. Neural networks are also applied to detecting activity and recognition of users' mobile app usage patterns identifying the risk of posing a potential privacy leak, where the probability distribution of neural network's output layer is exploited to detect unknown data.
- Cybersecurity/privacy protection tools & solutions applied in digital health, care, and wellbeing: Privacy protection schemes are needed to keep user information secure while ensuring users are in full control of their data sharing. This is particularly important in health, care, and wellbeing settings, where the data is collected through a multitude of sensors, stored, processed, or communicated. Similarly, users' activities on their smartphones have potential for privacy leak if attention is not paid. This may lead to unwanted profiling of users against their consent. Hence in both settings, techniques for not only securing the data but also protecting the users' privacy should be of utmost priority.
