Dr. Cohen earned her Ph.D. in Botany in 1993, with the focus of her thesis being "The Efficacy of Three Herbicides in Onion Crops in Jamaica". She has since worked on soil fertility and crop production, wile investigating the impact of herbicide use and other methods of weed control. Her current research involves studying the effects of solarization and mulching on plant-community interaction, the biocontrol agents of Chromolaena odorata; and the Growth and development of pomegranate (Punica granatum)in Jamaica.
