Dr. Sarvajeet Singh Gill is currently working as Professor (Asstt.) at Centre for Biotechnology, Maharshi Dayanand University, Rohtak, Haryana, India. Dr. Sarvajeet Gill's research includes abiotic stress tolerance in crop plants, reactive oxygen species signaling and antioxidant machinery, gene expression, helicases, crop improvement, transgenics, nitrogen & sulfur metabolism and plant fungal symbiotic interactions. Together with Dr. Narendra Tuteja at ICGEB, New Delhi, he worked on plant helicases for abiotic stress tolerance. His research uncovered new pathways to plant abiotic stress tolerance and indicates the potential for improving crop production at sub-optimal conditions. Sarvajeet Gill has edited several books with Springer, Wiley, Elsevier, CABI etc and has a number of research papers, review articles, and book chapters to his name. Recently, Dr. Sarvajeet Gill conferred with INDIA Research Excellence & Citation Award - 2017 from Clarivate Analytics (Web of Science).
