Research
Maral works on formal verification of learned policies — proving safety properties of deployed cells' policies in bounded environments. She co-authored the lab's verification framework paper (25/01) and is leading the cell-internal effort to weaken the boundedness requirement so that the verification approach applies to a wider class of practical environments.
She has been with alphabell since 2019. Her work is one of the clearer examples of the interpretability axis's structurally cross-cutting role: the verification framework is used by world-models cells whose environments fit the formal class, by agentic-axis cells whose policies are simple enough to verify, and by external partners who consume it through the open-source release.
Maral is based in Toronto. She presents the verification framework at non-AI venues — POPL, CAV, OOPSLA — as part of a deliberate effort to keep the work legible to the formal-methods community.
