Celebrating Richard Flagan's 50 years of service to @caltech.edu! Rick arrived in 1975 intending to study combustion chemistry and ended up playing an enormously influential role in developing new instrumentation to quantify atmospheric aerosol and helping to mitigate air pollution in LA and beyond.
