In 1951 he joined Imperial College as a research assistant, obtaining his PhD in 1954 for developing novel optical methods to analyse the structure of flames.

Professor Weinberg is distinguished for his optical and electrical studies of flames and his pioneering development of innovative combustion methods.

He developed novel combustion devices[4] incorporating distinctive heat exchangers, permitting the ignition and burning of very low calorific fuel-air mixtures.

His work on laser ignition has progressed to understanding hazards associated with the use of optical fibres in flammable atmospheres.

[7] His wide-ranging services to academia, industry and scientific societies included visiting appointments at universities in Europe, the US, Japan and Israel, consultancies for petroleum, chemical, aerospace and defence organisations and membership of committees and boards of governance of numerous scientific and professional bodies.
