Mann joined as Chief Scientific Officer of Indian Tea Association in 1900 and extensively traveled in Assam and North East India for scientific research on early tea plantations. He was instrumental to set up the world's first organised tea research institute at Tocklai, Jorhat, Assam (India) as Tocklai Experimental Station (later renamed as Tocklai Tea Research Institute). Mann immensely contributed in the field of tea pest and disease, soils, manuring, agricultural practices.
