Profile Summary

I am currently working as a Postdoctoral Fellow with a strong research background in environmental science, hydrology, land-use dynamics, sediment studies, and data-driven environmental assessment. My academic and professional experience involves interdisciplinary research, scientific writing, manuscript preparation, data analysis, and publication-oriented research support. I completed my PhD with specialization in sediment fingerprinting and watershed-related studies, where I worked extensively on spatial analysis, environmental modeling, GIS and remote sensing applications, and statistical interpretation of environmental datasets. My research work has focused on understanding the impact of land-use and climatic changes on hydrological and agricultural systems. My previous and ongoing research projects include: • Impact of spatio-temporal land-use dynamics on rice cropping patterns and agricultural production • Sediment yield assessment and land-use change modeling using CA-Markov and GeoWEPP approaches • Soil carbon dynamics under changing cropping patterns in India • Climate variability and rainfall trend analysis using spatial datasets and remote sensing products • Hospital wastewater management and environmental monitoring • Watershed hydrology, erosion processes, and sediment source apportionment studies I have experience working with: • Academic manuscript writing and editing • Literature review and synthesis of scientific findings • Reviewer comment responses and manuscript revision support • Statistical and geospatial data analysis • GIS, Remote Sensing, Python, and environmental modeling tools • Preparation of publication-quality figures, tables, and reports In addition to research, I have experience supporting academic publications through editing, formatting, proofreading, and improving the clarity and structure of manuscripts intended for peer-reviewed journals. I am comfortable working on detailed research-intensive tasks, meeting deadlines, and independently managing long-term projects. My educational and research background has helped me develop strong analytical, technical, and academic communication skills, particularly in handling interdisciplinary scientific and research-oriented assignments.
