From Game Engineer to Scientist at ISRO to the world of Metaverse
My journey has been anything but conventional. It all started in the late 1990s, when I was deeply immersed in the world of game development. Fast forward to today, I find myself contributing to advancements in Natural Language Processing (NLP) and exploring the fascinating potential of the Metaverse. This transition, from being a game engineer to a scientist at ISRO and now focusing on NLP and virtual worlds, has been driven by a blend of curiosity, adaptability, and a passion for technology.
Early Days in Game Development
In the late 1990s, the gaming industry was still in its early stages, and the tools we have today—like Unity or Unreal Engine—didn’t exist yet. I was fascinated by the idea of creating immersive virtual worlds, so I decided to build my own game engine. Using DirectX, OpenGL, and C++, I developed a game engine that could handle complex 3D graphics, which was a big challenge at the time.
It was a passion project, but little did I know that this experience would lead to something much bigger. The skills I developed in game development, particularly in creating interactive 3D environments, would play a crucial role in the next phase of my career.

In 2000, my expertise in game engine development unexpectedly opened a door to ISRO, the Indian Space Research Organisation. ISRO was looking for individuals who could create 3D software for their space missions, including the Chandrayaan and Mars Orbiter missions. My background in game development was a perfect fit, and I joined the team as a scientist.
At ISRO, I worked on various projects that combined technology and history. One of the most fascinating was my work on the Saraswati River project, where I used remote sensing technology to analyze satellite images and trace the ancient river’s path across Northwestern India. This blend of technology and history piqued my interest in ancient texts like the Ramayana, Mahabharata, and the Vedas, which would later guide me into the world of Natural Language Processing (NLP).
Exploring Ancient Texts with NLP
My curiosity about ancient texts led me to dive into the field of Natural Language Processing (NLP). Back in 2009, NLP was still in its infancy, and it wasn’t as widely used as it is today. I began working on parsing ancient texts using computational techniques, focusing on extracting grammatical structures like nouns, verbs, and objects from complex sentences.
At that time, NLP was far from mainstream, and tools like ChatGPT didn’t even exist. My work was pioneering in its own right, as it laid the groundwork for future advancements in the field of AI and NLP. Over the years, NLP has evolved tremendously, and today, we see AI tools like ChatGPT that can process and generate human-like text, all thanks to the foundational research done back in the early 2000s.
Text Analysis through NLP and Geography
The study of ancient texts, such as the Mahabharata, is no longer limited to traditional methods. Thanks to advancements in Natural Language Processing (NLP) and modern geographic analysis tools, we can now extract valuable insights from vast volumes of text and connect them with real-world geographical data. This combination of technology and history provides us with a clearer picture of ancient societies, their cultures, and the landscapes they inhabited.
Text Parsing and Information Extraction Using NLP
One of the most powerful applications of NLP is text parsing, where large volumes of ancient literature, such as the Mahabharata with its 100,000+ verses, are analyzed to identify key entities, events, and relationships.
Entity Recognition
NLP algorithms are capable of extracting important terms like names, places, and events from ancient texts. For example, a text parser could identify all instances of the “Pandavas” or “Arjuna” and map out their relationships with other characters or entities in the text.
- Key Entities: These include characters (e.g., “Pandavas,” “Arjuna”), places (e.g., “Hastinapura,” “Kurukshetra”), and objects (e.g., “bow,” “chariot”).
- Relationships: By analyzing sentence structure, NLP tools can also map out the relationships between these entities. For instance, how the Pandavas interacted with other kingdoms or their travels across India.
Pattern Recognition and Relational Mapping
Once entities are recognized, the next step involves grouping sentences that contain specific entities. This allows for the creation of relational maps, where the connections between characters, their journeys, and their relationships with various places and events are documented.
- Example: Connecting the journeys of Arjuna, tracking his travels across different kingdoms, and linking those locations with historical or geographical data.
Automated Page Creation for Documentation
By using NLP, structured outputs such as web pages, charts, or data visualizations are automatically generated. These tools document the insights gathered from text analysis, creating a comprehensive, easy-to-understand record of the relationships and events described in ancient texts.
Leveraging Geography Skills and Tools for Deeper Insights
NLP is not the only tool helping researchers gain insights into ancient texts. Geographic analysis plays an equally important role in understanding the places, terrains, and environments described in these texts.
Map Analysis: Modern Tools Meet Ancient Geography
- Google Maps: Modern geographic tools like Google Maps are used to correlate ancient texts with current geographic locations. This can help pinpoint locations mentioned in texts, such as the cities, rivers, and mountains referenced in epics like the Mahabharata.
- Hydrology and Topography Maps: These maps allow researchers to analyze river systems and terrain elevations, helping to understand how ancient civilizations interacted with their environment. For example, understanding how the ancient Saraswati River, mentioned in the Vedas, once flowed through what is now a desert region.
- Paleogeographic Maps: These maps account for historical changes in geography, such as sea-level fluctuations post-Ice Age. This information is crucial for understanding how regions like Gujarat evolved over time due to changes in coastlines and landmasses.
Paleoenvironmental Data and Historical Cartography
- Benthic Maps: These maps show the depth of oceans and submerged lands, offering insights into how coastlines and landmasses shifted over time. Studying regions like Gujarat, which has seen significant changes due to fluctuating sea levels, gives us a clearer view of the environmental conditions in ancient times.
- Historical Cartography: Comparing modern maps with ancient descriptions from texts can help locate lost cities, identify ancient trade routes, and map out historical landmarks. This cross-referencing of ancient texts and modern maps is an essential tool in archaeological and historical research.
Synthesis: Integrating Textual and Geographical Insights
Effective research requires more than just the ability to parse texts and analyze maps—it involves synthesizing information from multiple sources.
Familiarity with Ancient Texts
Reading and understanding ancient texts is crucial. Researchers need to gain contextual knowledge to complement computational analysis. Understanding the cultural, religious, and social contexts of these texts provides a richer perspective on the data extracted by NLP.
Cross-Referencing Information
Cross-referencing ancient texts with modern geographic data and historical records is essential. It ensures that the insights gathered are accurate and reflect both ancient and contemporary knowledge.
Visualization Tools
Once insights have been gathered, they are mapped visually using tools like GIS (Geographic Information Systems) or custom-built visualizations. These tools help bring together ancient descriptions and modern geography, providing a visual representation of how past societies interacted with their environments.
Bridging Ancient Texts with Modern Technology
The integration of NLP and geographic analysis isn’t just about theoretical research; it has practical applications that bring ancient history to life.
Identifying Ancient Routes and Timelines
By combining NLP with geographic tools, researchers can trace the routes taken by ancient characters or document the spatial relationships between key events in history. This information can be used to create timelines or visual maps that align ancient narratives with actual geographic locations.
Understanding Environmental and Societal Contexts
Geographic analysis and NLP also help us understand the environmental settings in which ancient stories took place. For instance, by studying hydrology and topography maps, we can gain insights into how rivers, mountains, and other natural features influenced ancient societies.
Creating Educational and Research Platforms
Insights gathered from these analyses can be fed into books, academic research papers, or online platforms, where they can be shared with a global audience. By documenting ancient events, timelines, and geographical correlations, we can make ancient history more accessible and engaging for modern readers.
