• My research focuses on Biochemistry, with a strong emphasis on understanding biomolecules, their interactions, and their functional significance in living systems.
• I work extensively in Phytochemistry, analyzing plant-derived compounds, their structural characterization, and their biological or therapeutic potential.
• My studies involve evaluating the antioxidant, antimicrobial, and bioactive properties of phytochemicals using advanced biochemical assays.
• In the field of Microbiology, I investigate antimicrobial activity, pathogenic mechanisms, and the effects of natural compounds on microbial growth and survival.
• Overall, my research integrates biochemical mechanisms, phytochemical profiling, and microbiological evaluation to explore natural compounds for health and biomedical applications.
