Professor Frank Martin

Lead Scientific Expert

Frank has many years of experience as a world-leading researcher in toxicology, regenerative medicine and biospectroscopy. In the 1990’s at the Institute of Cancer Research, he undertook research into molecular carcinogenesis in breast/prostate cancer and developed short-term genetic toxicology assays. Frank has published prodigiously and has >300 research articles in leading peer-reviewed journals such as Nature journals, Proceedings of the National Academy of Sciences USAStem Cells, etc. He has served on the Editorial board of several leading peer-reviewed journals and was an external nominator for the 2013 Nobel Prize for Chemistry.


Professor Maneesh Singh

Lead Expert - Science & Medicine

Dedicated to using innovation to improve health care and diagnostic medicine, Professor Maneesh Singh was a pioneer and early adopter of Robotic Surgery. Whilst his achievements as a surgeon are incredible, Maneesh has also worked in scientific research, possessing a particular interest in Endometriosis. In addition, his work in obstetrics led to the development of the “Dermal Repair Formula” to reduce Keloid scars at Caesarean section.

He has recently worked with Prof. Frank Martin to develop a rapid, 90-second game-changer for Covid-19 Testing using infrared micro-spectroscopy, published in the national press. Maneesh, Frank and Paul Waldeck are also developing solutions and products around Medical Diagnostics as a Service to protect people better from Long-Covid, other medical conditions such as diabetes and health metrics, generally.

Dr Rhys Thomas

Dr Rhys Thomas M.M.’B.Bs., M.D., FRCA., Dip.I.M.C., R.C.’Ed.

Lead Expert - Respiratory Diseases & Biological Agents

Rhys is a former military Doctor; he trained and undertook his PhD at the globally renowned Defence, Science & Technology Laboratories (DSTL) Porton Down. He is a Consultant Anaesthetist; an expert in biological pathogens and respiratory diseases and one of the only two successful winners of the U.K. Government’s Covid Ventilator Challenge to invent, gain regulatory approval and to take to market, a highly effective new ventilator to treat coronavirus patients. He has also returned, part-time, to the frontline of the NHS to help in the fight against Covid.

Alongside his work treating patients with coronavirus at U.K. hospitals, Dr Thomas leads on the medical and scientific aspects of PP-L’s solutions to help organisations prevent the spread of COVID-19 and other pathogens in their operational activities.
