Generative Artificial Intelligence and Purpose-Built Software Consulting Services

Accelerated Review - Generative AI tools allow RedSpire to synthesize scientific literature, regulatory documents, and case records ethically and transparently at unprecedented speed. They provide clients with a comprehensive evidentiary foundation in days, not weeks.

Advanced Exposure Modeling - RedSpire integrates deterministic and probabilistic models—including dispersion and receptor-based approaches—with transparent assumptions, delivering quantitative reconstructions.

Quality Assurance - Software-driven error detection continuously flags inconsistencies, identifies gaps, and evaluates reference quality.

Secure Collaboration and Reporting - RedSpire uses technology to improve analysis while protecting confidentiality: confidential access, no training conducted using client data.

Dr. Kristen Good, MEM, PhD, CIH, Principal Health Scientist; Epidemiologist and Industrial Hygienist is passionate about applying data-driven, scientifically-supported solutions to public health problems. In addition to her technical subject matter expertise and strong scientific background - bringing over a decade of experience advising partners on incident/emergency responses and leading programmatic initiatives related to air pollution exposures, indoor air quality, and respiratory disease; wildfires, communicable disease outbreaks, and occupational health - she is also an experienced supervisor/team leader and project manager responsible for grant administration, contractor relationships, and fiscal management.

Dr. Good has over 15 years of scientific background and experience in risk assessment, toxicology, exposure assessment, and environmental sciences, across academia/research, private industry, and government sectors. I have led design, implementation, and data analysis for multiple large human participant research studies and laboratory-based chemical emissions monitoring campaigns. I have Designed and executed multi-million dollar public health initiatives, including: a $53-million statewide program that delivered over 45,000 portable HEPA air cleaners to over 1,500 K-12 schools and early childhood education centers within a rapid 9-month period; a $20-million small grants program that provided funding for community-based COVID-19 recovery efforts to 68 local non-profits; and a $4-million initiative to conduct indoor air quality and ventilation assessments and improvement efforts in workplaces and community buildings throughout the state. In 2025, I cofounded a consulting firm that is focused on the application of AI-based technology.
