She was formerly the David Edward Schramm Professor of Electrical and Computer Engineering at Carnegie Mellon University.

[3] "Our proposed power management techniques include the use of Voltage Frequency Islands (VFI), where we are able to guarantee a certain performance level with minimum power, even under decreased reliability or increased variation," Marculescu said.

The proposed power management mechanism will also ultimately help cut energy costs."

She was named Fellow of the Institute of Electrical and Electronics Engineers (IEEE) in 2015[4] for contributions to design and optimization of energy-aware computing systems.

She was elected as an ACM Fellow in 2019 "for contributions to the design and optimization of energy-aware computing systems".
