Dr. Sunita Singh

Short Bio

Dr. Sunita Singh is a distinguished academic and researcher serving as Assistant Professor of Chemistry at Navyug Kanya Mahavidyalaya, University of Lucknow. Since earning her Doctorate from DDU Gorakhpur University in 2015, she has established herself as a leading authority on the bioactive properties of botanicals, with a specialized focus on the antioxidant and antimicrobial potential of spice essential oils and oleoresins. A former UGC Research Fellow, Dr. Singh's scholarly portfolio is extensive, featuring over 40 peer-reviewed research articles and 15 book chapters. Her rigorous analytical work on Piper nigrum (black pepper) and Nigella sativa (black cumin) has significantly advanced our understanding of natural preservatives and therapeutic agents. Beyond her primary research, she is a prolific editor and reviewer, maintaining high standards of scientific integrity within the global academic community. Her commitment to food safety and international scientific cooperation is further evidenced by her active membership in the Global Harmonization Initiative (GHI). Dr. Singh continues to bridge the gap between traditional botanical knowledge and modern chemical analysis, making her a vital voice in contemporary phytochemistry.

Extended Bio

Dr. Sunita Singh is a chemist who reads the wisdom of traditional medicine systems and translates it into the language of modern analytical science. Her career is built on a deceptively simple premise: that the plants humans have used for centuries to flavour food and treat ailments deserve rigorous scientific scrutiny — not as folklore, but as chemistry.She earned her Ph.D. from DDU Gorakhpur University in 2015, and from the beginning, her research has been defined by focus and precision. Rather than casting a wide net across dozens of plant species, she has gone deep on specific candidates — Piper nigrum (black pepper) and Nigella sativa (black cumin) — subjecting them to the full arsenal of modern analytical techniques. Her work on the essential oils and oleoresins of these spices has produced detailed chemical profiles, identified the specific compounds responsible for antioxidant and antimicrobial activity, and established dose-response relationships that move beyond anecdotal claims into reproducible science.This is not ornamental research. The search for natural preservatives and therapeutic agents is urgent. As the food industry grapples with consumer demand for clean labels and fewer synthetic additives, and as antimicrobial resistance renders conventional antibiotics less effective, the kind of systematic phytochemical work Dr. Singh conducts becomes increasingly consequential. Her over 40 peer-reviewed articles and 15 book chapters represent a sustained contribution to a field that matters not just academically, but practically.As a former UGC Research Fellow, she understands the discipline required to secure competitive funding and execute long-term research programs. As an editor and reviewer, she upholds the standards of evidence and argument that keep scientific publishing credible. And as an active member of the Global Harmonization Initiative (GHI), she participates in international efforts to align food safety regulations across borders — a reminder that science, at its best, is a collaborative enterprise that transcends national boundaries.At Navyug Kanya Mahavidyalaya, University of Lucknow, Dr. Singh brings this research experience directly into the classroom and the laboratory. She teaches her students that analytical chemistry is not a set of abstract techniques but a toolkit for answering questions that matter: What is in this plant? How does it work? Can we use it safely? She writes for the food scientist looking for evidence-based alternatives to synthetic preservatives, the pharmacologist investigating plant-based therapeutics, and the student who wants to understand how traditional knowledge and modern chemistry can inform each other.

Primary Beats

• Phytochemistry & Bioactive Natural Products: Chemical characterization of essential oils, oleoresins, and plant extracts; identification and quantification of bioactive compounds using chromatographic and spectroscopic methods; structure-activity relationships of plant-derived antioxidants and antimicrobials.
