ज्ञानकर्मसमुच्चयवाद
My work centers around the processes by which we create and communicate knowledge, and how those processes shape our institutions. In particular, my interests lie in understanding how information is created through the communication process, how knowledge is structured by the rhetorics of modernity. I employ and advocate for mixed methods approaches, leveraging the science of complex systems and natural language processing as novel methods for deconstruction and critique alongside corpus and ethnographic approaches. This theoretical emphasis is not without practical goals, as the core of my research ethos is the belief that only though a combination of theory and action can we achieve the liberation we are seeking--a sentiment reflected by the Sanskrit word shown above.
