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 in the Hydroinformactics team. 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.

I am a design nerd. I like typesetting documents in LaTex. I am passionate about open-source science and software; I extensively use and contribute to open-source tools. I enjoy tinkering with microcontrollers and sensors. I am obsessed with coffee and all its derivatives. I enjoy traveling, hiking, and exploring different cuisines. I love playing video games, reading fiction, and occasionally non-fiction.

Research

I am interested in optimization, real-time control, and machine learning, and their application for addressing water challenges. I also enjoy building wireless sensor networks: designing backend infrastructure, prototyping sensors, and laying out custom hardware.
