Prior to the startup role, he spent over 5 years as a systems engineer to provide consultation to various key players in testing and prototyping products in the wireless technology field. His early academic careers involved collaboration with Nokia and Philips R&D team.



Brian holds a 1st Class BEng (Hons) in Electronics and Electrical Engineering, MSc in RF Communications Engineering, MPhil in RF Waveform Engineering and a PhD in Medical Physics Instrumentation and Digital Signal Processing.



Dr Lothar Wentzel
AI and Machine Learning Expert

Lothar Wenzel holds a PhD in Mathematics from EMA Universitat, Germany and Dipl.-Ing (Master) Computer Science from TU Dresden, Germany. He has over 30 years experience in the fields of measurement, control, image processing and pattern recognition and machine learning. He has implemented real-time solutions for simulation and deployments to multi core CPUs, FPGAs and GPUs. He has been awarded 30 patents, is a respected author of numerous books and papers and was awarded the prize for the solution to the Makhoul conjecture at the 2000 DSP world conference. 



Jonathan Griffiths
AI and Machine Learning Engineer
Dr David Slater
Safety and Cyber Security Expert

Dr David Slater is an expert in human centric algorithm development. He specialises in  the application of Bayes algorithms for augmenting predictions to improve safety and reduce risk. He work allows modelling of 'what-if' scenarios to improve the overall system prediction model. 


Jonathan is experienced in the development of custom neural networks, deep convolutional neural networks (DCNN), recurrent neural networks (RNN) and various machine learning regression algorithms. He has developed and deployed pipelines for supervised and unsupervised learning as well transfer learning pipelines in Python and TensorFlow. In addition he has implemented multi variate time series forecasting and Image augmentation solutions using the above techniques.

Jonathan graduated from Cardiff University in 2016 and holds a 2:1 BEng in Electrical and Communications Engineering. He attended post graduate courses in AI and machine learning. He is a competent software developer in Python, LabVIEW and C++ and has developed machine learning solutions using Scikit, Keras and TensorFlow frameworks on Microsoft Azure, Google cloud and Amazon platforms.



He is currently an Honorary Professor in the School of Engineering at Cardiff, where he is involved with developing and teaching the evolution of tools and applications in risk and safety. This extends the core disciplines of “SAFETY I” and Human Reliability (Behaviour Based Safety) to the newer complementary approaches in Human and Organisational Performance (SAFETY II). These involve a close association with Erik Hollnagel on the formal development of the new FRAM and Resilience approaches.
