Swadhin Pradhan

I currently work at Cisco Meraki as a Research engineer, where we are trying to bring machine-learning driven intelligence across Meraki's networking products. Previously, I graduated in Computer Science from University of Texas at Austin with a PhD.

My research is focused on wireless sensing, machine learning, and internet-of-things(IoT). Recently, I have started working on building Large Generative Model (e.g., LLM) for X type data where X type is not {Text, Image, Audio or Video}.
