Dr. Aran Castro A J — Full Bio (≈1000 words)

Dr. Aran Castro A J is a GIS Manager, research consultant, author, and founder of Geospatial Campus — a small geospatial studio based in Nagercoil, Tamil Nadu, with operating presence in Kochi and Chennai through partner campuses. He holds a Ph.D. in Applied Geology and works at the intersection of geology, remote sensing, GIS methodology, and academic research support, with a particular focus on the coastal and inland hydrological systems of southern India.

His doctoral research was conducted across years of field-based coastal investigation, working with shoreline data on paper before he understood, the first time he traced a shoreline through DSAS rather than by hand, that the bottleneck for most Indian PhD scholars was not intellect or effort but the gap between knowing a research question and being able to execute it geospatially. That recognition became the founding observation behind Geospatial Campus, which he started running in 2014 and registered as a Micro, Small and Medium Enterprise (MSME) unit under Udyam TN-09-0048222.

Geospatial Campus runs three streams of work in parallel. The first stream is structured, hands-on training in GIS and remote sensing — for undergraduates entering geospatial work, postgraduate scholars adding GIS to their research, faculty integrating geospatial methods into teaching, and working professionals adding geospatial capabilities. The flagship training programme is a three-month Advanced Spatial Data Science course covering thirteen modules from GIS fundamentals through deep learning integration in ArcGIS Pro. Beyond this, Dr. Castro delivers shorter intensive workshops on LULC change detection, shoreline change analysis using DSAS, coastal vulnerability index (CVI) construction, hydrological modelling, and publication-quality cartography.

The second stream is research and publication support for PhD scholars. Dr. Castro is best known among Indian PhD scholars for end-to-end engagements that take a research question — typically resting in spreadsheets months after fieldwork — through to a defendable Scopus or SCI-indexed manuscript. The flagship of this stream is the 14-Week Publication Bridge, a co-authored programme for mid-stage scholars in Year 2 or Year 3 of their doctorate, structured across distinct phases of audit, analysis, figure production, drafting, revision, and submission. The programme is offered in two tiers: a co-authored tier in which Dr. Castro is named as co-author per ICMJE criteria, and a sole-author tier in which the scholar retains sole authorship with the supervisor and Dr. Castro is credited in acknowledgements. Smaller scoped add-ons — a Methodology Sprint for early-stage research design, and a Figure & Map Polish for late-stage drafts — are available outside the full Bridge.

The third stream is consulting for institutions, government bodies, NGOs, and private organisations that need decision-grade geospatial outputs. Recent engagements span coastal vulnerability assessments, multi-temporal LULC change studies for urban districts, environmental impact spatial analysis, hydrological and watershed analytics, climate trend analytics, and faculty development programmes. Past institutional engagements include the University of Madras (Department of Applied Geology), Indian Institute of Remote Sensing (IIRS), SRM University, and TRP Engineering College.

Dr. Castro is the author of three published books, each anchored in primary research or hands-on practice. Mapping Peace explores the geospatial cartography of post-conflict and recovery landscapes. Systems Over Software is a methodological playbook for GIS researchers, arguing for spatial reasoning over button-clicking and offering frameworks for moving from raw data to interpretable analysis. Coastal Geomorphology is a field-and-lab reference covering the processes, landforms, and human interactions that shape coastal zones. All three are available as free PDFs from draran.online and in print on Amazon.

His public-facing teaching extends beyond paid programmes. Dr. Castro publishes free, research-grade toolkits and workflow manuals on the practical side of GIS research — covering Land Surface Temperature mapping in ArcGIS Pro using Landsat 8, lecture notes on Landsat and Airbus satellite constellations, hydrology workflows from DEM preparation through stream order classification, and Digital Shoreline Analysis using DSAS with EPR, LRR and NSM calculation. These toolkits are downloaded by scholars across India and South Asia.

He holds active institutional roles as researcher with the Institute for Coastal Water Management (ICWM), and as Professor of Practice at Holy Cross College, Nagercoil, where he also sits on the academic Board of Studies. He is a frequent invited resource person and speaker at academic institutions across South India, with recent engagements including the University of Madras National Workshop in 2026, the Holy Cross College Board of Studies and National Science Day programmes, the Nesamony Memorial Christian College Invited Talk, the Stella Mary's College QGIS Workshop, the EASA College Workshop, the Arunachala College Workshop, and the Kangeyam Institute of Technology QGIS Workshop in collaboration with IEEE GRSS and Geospatial Campus.

Dr. Castro maintains an ORCID profile (0000-0001-8038-606X), a public LinkedIn presence at /in/drarancastro, a GitHub presence at /AranCastro, and an Amazon Author store. His Google review profile holds a 4.8 / 5 rating across 54 reviews from training cohorts, FDP participants, and research-support engagements.

He works primarily in person from the Nagercoil studio and remotely from Kochi and Chennai through partner campuses run by Ajith Chandran and Karthika respectively, and travels across India for institutional FDPs and on-site consulting engagements. The studio operates Monday through Saturday, 9 a.m. to 6 p.m. Indian Standard Time, with a same-day reply discipline on WhatsApp enquiries.
