His specialization is in wastewater treatment, phycoremediation, metal toxicity, stress physiology, antioxidants defense mechanisms, and biofuel production. Singh has presented and participated in several state and national conferences, seminars and workshops.Dr. Fernanda Maria Policarpo Tonelli is specialized in Molecular Biology and has been studying biotechnological topics like gene delivery approaches (using engineered viral particles and nanomaterials) aiming transgenesis. She has taught topics related to Biochemistry and Molecular Biology to graduate students. Dr. Tonelli has authored 12 scientific articles and more than 20 book chapters from international publishers and has reviewed various articles/book proposals. She has presented and participated in numerous national and international conferences and has also had the opportunity to contribute to the organization of various scientific events. Dr Tonelli has also dedicated herself to promote Science and Technology co-funding an ONGwith this purpose and also joining a scientific divulgation group composed only by women. She has had her efforts as a researcher recognized by various awards (including For Women in Science Brazil-L’Oreal/UNESCO/ABC and Under30 Brazil – Forbes) and certificates of merit.Dr Khalid Rehman Hakeem (PhD, FRSB) is presently working as Professor at King Abdulaziz University, Jeddah, Saudi Arabia. After completed his PhD (Botany; specialization in Plant Ecophysiology and Molecular Biology) from Jamia Hamdard, New Delhi, India in 2011, he has worked as Assistant Prof. at the University of Kashmir, Srinagar for a short period. Later he joined Universiti Putra Malaysia, Selangor, Malaysia and worked there as Post Doctorate Fellow in 2012 and Fellow Researcher (Associate Prof.) from 2013-2016 respectively.
