The author is a passionate researcher and an academic specializing in forensic linguistics, big data language analysis, and corpus linguistics. With a deep curiosity for how language reveals identity, intention, and emotion, she has spent years exploring the digital traces left in Indonesian communication—from WhatsApp chats to social media posts—uncovering how even the smallest linguistic choices can speak volumes.

Holding a Ph.D. in Linguistics from Universitas Gadjah Mada, the author combines rigorous academic training with a flair for making complex concepts accessible. Her work often blends qualitative sensitivity with computational precision, reflecting a commitment to bridging classical linguistic theory with modern digital realities. This book represents a culmination of her journey through language, identity, and the digital age—delivered not just as a scientific endeavor, but as a narrative full of insight, pattern, and purpose.
