How We Work

A Consortium of Scientific Experts for Global Drug Development

SGI Consulting is led by Christopher W. Stewart, PhD, DABT, Founder and Principal Consultant, with program support from Annette Stewart, Program Manager. Together, they provide the leadership, scientific direction, and coordination needed to support Sponsors through complex nonclinical and regulatory development programs.

In addition to its core leadership, SGI Consulting operates as a consortium of experienced subject matter experts. This model allows SGI to bring together specialized scientific, regulatory, clinical, CMC, toxicology, pathology, and medical writing expertise based on each Sponsor’s program needs.

Rather than offering a one-size-fits-all consulting team, SGI coordinates the right experts at the right time. This flexible approach helps Sponsors access targeted guidance, practical recommendations, and efficient support across nonclinical drug evaluation, regulatory submissions, and global development planning.
