S. L. Kochhar obtained his master's degree from Punjab University, Chandigarh, where he was awarded the prestigious Atomic Energy Commission Scholarship. He taught courses in economic botany and plant physiology at Sri Guru Tegh Bahadur Khalsa College, University of Delhi, for more than four decades (1965–2009). His areas of interest include botany, plant science, tropical crops and plant physiology. He is author of Economic Botany: A Comprehensive Study, 5th Edition (Cambridge, 2016). Sukhbir Kaur Gujral has been teaching in the Department of Botany at Sri Guru Tegh Bahadur Khalsa College, University of Delhi for more than three decades. Her areas of interest include plant physiology and cell biology.
