Dr. Frake is an experienced engineering physicist who has provided multidisciplinary technical consulting services to clients in systems-level engineering, research & development, testing, failure analysis and safety / reliability of products. He works across all stages of the product lifecycle to encourage a holistic approach in the product development process for product innovation, safety, and reliability. Dr. Frake has worked extensively in the fields of medical devices, batteries, and sensing / metrology and is experienced in failure investigations and standards / regulatory compliance for products and manufacturing.

Dr. Frake has helped his clients throughout the product and technology development lifecycle, including early-stage innovation and concept generation, concept assessment, market research, technology landscaping, proof of principle testing, mathematical modelling, algorithms, data analysis, and prototype development. He has worked across many industries, including medical devices, pharmaceutical, oil & gas, mining, electric vehicles, consumer devices, industrial and the food & drink industry. His specific engineering experience includes developing novel sensors and detection systems, designing and building measurement and metrology devices, temperature control and cryogenic systems, wireless power, and general electromagnetics.

Dr. Frake’s PhD was in the electrical measurement of quantum semiconductor devices at high frequencies, for applications in quantum computation, novel electronic density of states measurements, charge pumping, and primary thermometry. During his PhD, he developed skills in semiconductor fabrication, semiconductor device analysis and testing, optical and e-beam lithography, SEM and AFM techniques, precision electrical measurements and RF electronics. To engage with his research, Dr. Frake also became experienced with cryogenic systems including Helium 3 and dilution refrigerators, superconducting magnets, and high vacuum systems. Before joining Exponent, Dr. Frake worked as a consultant at Sagentia Ltd., a science, technology and product development consultancy in Cambridge, UK.
