Profile Name

Hello, I am అభిరామ్‌ ముళ్ళపూడి (Abhiram Mullapudi). I build digital water systems. Akin to autonomous cars, these digital water systems autonomously monitor and operate themselves to "squeeze" more performance out of our physical water networks and create resilient water infrastructure. I work as a Senior Data Scientist at Xylem. At Xylem, I design machine learning-based analytical methodologies, develop software infrastructure, and build wireless sensor networks to help cities and utilities better manage their water infrastructure. I have a Ph.D. in intelligent infrastructure systems from the University of Michigan, Ann Arbor.

Identification of stormwater control strategies and their associated uncertainties using Bayesian Optimization

Abhiram Mullapudi, Branko Kerkez

In preparation, 2023

poster/ paper

Bayesian optimization is a automated data-driven approach for identifying a control strategy that achieves the desired response from the stormwater network.

Deep Reinforcement Learning for the Real Time Control of Stormwater Systems

Abhiram Mullapudi, Matthew J. Lewis, Cyndee L. Gruden, Branko Kerkez

Advances in Water Resources, 2020

code / paper

Reinforcement learning can be used for creating autonomous stormwater systems that can dynamically change their behavior based on the state of the watershed for achieving system scale objectives.


rrcf : Implementation of the Robust Random Cut Forest algorithm for anomaly detection on streams

Matt D. Bartos, Abhiram Mullapudi, Sara C. Troutman

Journal of Open Source Software, 2019

code / paper

Anomalies in the streaming data can be detected by estimating the shift in the structure of the random forest caused by the addition of a new data point.


Shaping streamflow using a real-time stormwater control network

Abhiram Mullapudi, Matt D. Bartos, Brandon P. Wong, Branko Kerkez

Sensors, 2018


Response of a stormwater network can be precisely shaped with the data from a wireless sensor network.


Building a theory for smart stormwater systems

Abhiram Mullapudi, Brandon P. Wong, Branko Kerkez
