About

I am a research scholar in linguistics at Deccan College Post-Graduate and Research Institute (deemed to be a university), Pune, India. My research lies at the intersection of forensic linguistics, cognitive linguistics, psycholinguistics, computational linguistics, artificial intelligence, and cybersecurity.

My master's dissertation develops the L1 Interference Feature Set (LIFS), a nine-feature stylometric framework designed for authorship attribution, deception analysis, and regional dialect profiling in multilingual Indian fraud communication. As part of this work, I constructed the first purpose-built multilingual phishing corpus for forensic linguistic and Native Language Identification (NLI) research in the Indian context, comprising 381 texts spanning 11 Indian state zones and 9 large language model platforms.

My current research examines AI-generated adversarial texts, generative fraud communication, multilingual authorship attribution, and explainable language-based forensic systems. I am particularly interested in how linguistic variation, native-language interference, and stylistic markers can support attribution and threat intelligence in increasingly AI-mediated communication environments.
Before entering academia,

My second research explores the intersection of forensic linguistics, cognitive linguistics, artificial intelligence, and institutional trust.
I am developing a broader theoretical framework of Cognitive Infrastructure, examining how language, metaphor, and narrative shape human reasoning, machine behaviour, and institutional decision-making.

I spent more than twenty-five years in advertising and marketing communications. This professional background informs my interest in persuasion, audience design, strategic communication, and deceptive discourse. I have native competence in Punjabi, Bhojpuri, and Hindi and academic fluency in English.

Alongside my research, I write poetry and reflective prose, exploring the relationships between language, metaphor, nature, and human experience.
