Rajasekhar Anguluri

Postdoc @ Arizona State University. Brews simple math from engineered systems

I’m interested in how engineering systems work at the deepest levels, which steers me to do research in systems theory. My current research identifies situations where estimation, identification, and control problems in large-scale systems (e.g., power and mechanical systems) can be solved using data science methods with theoretical guarantees. Situations:

  • estimation and control
    • sparse state and input estimation in dynamical systems
    • controllability of coarse dynamical systems
    • structured system identification
    • structure learning in graphical models
    • attack design and detection in network systems
  • applications to power systems
    • parameter estimation in low-inertia systems
    • topology learning in distribution grids
    • oscillations and cyber-attack detection/localization/mitigation in bulk systems

Academic roots: I’m Postdoc-ing in the School of ECEE at Arizona State University, where I work with Lalitha Sankar, Oliver Kosut, and Gautam Dasarathy. I received a PhD in Mechanical Engineering from University of California, Riverside. My thesis (security of stochastic dynamical systems) supervisor was Fabio Pasqualetti. At UC Riverside, I took a bunch of courses in Statistics and earned an MS degree, but I remember only 51.32% of the course material.

In my free time, I either listen to audiobooks on philosophical aspects of ethics and science or remember my early adolescent memories or think about the dense hair I had ages ago. If you like to chat, drop me a line via email.
