Hi! I am అభిరామ్ ముళ్ళపూడి (Abhiram Mullapudi). I build cyber-physical infrastructure systems and am currently focused on digital water systems. My work combines embedded systems, machine learning, and physical modeling to develop advanced control systems for operating water infrastructure. I work as a Senior Data Scientist at Xylem. I am particularly interested in wireless sensor networks, time series forecasting and anomaly detection, and optimization, especially in graph networks.
