[1] Poirazi is known for her work in neurobiology where she focuses on dendrites, the portion of a neuron that propagates signals.

Her early research generated predictive models of how active dendrites and structural plasticity enhance storage capacity in single neurons.

[5][6] Poirazi has built a circuit-level model of the hippocampus that shows how memories are linked through time.

[7] She has developed and applied biophysical models to explain how human neurons compute information, with a focus on solving the XOR problem.

[10] In 2018, she received a Friedrich Wilhelm Bessel Research Award from the Alexander von Humboldt Foundation.
