The record
Senior Economist at Eastern Research Group. In 2021 NMED offered her as a technical witness in EIB 21-27(R), its oil-and-gas ozone-precursor rulemaking, where she testified that she had been asked to provide testimony "in support of" the Department's proposed regulations, describing analysis ERG performed using data NMED supplied.
She is also the ERG representative whom Max Shepherd identified, in July 2026, as the person completing the individual service contract he said he needed before he could perform hearing-officer duties in this matter. Nothing in the record establishes that she selected him, directs him, evaluates him, or acted improperly, and the filing that surfaced this says so explicitly.
