He earned his M.D. from Loyola University Chicago Stritch School of Medicine and his J.D. from DePaul University College of Law. He is board-certified in internal medicine and pediatrics and completed his residency at the University of Michigan Medical Center. He also serves on the Weinberg College of Arts and Sciences Board of Visitors at Northwestern University and is a member of the Easterseals National Board of Directors.
Dr. Safavi is a lifelong Chicagoan.

Nishant Nayar
Nishant Nayar has spent over two decades at the intersection of data, technology, and business, working across investment banking, commercial banking, and asset management. He specializes in translating complex data into practical insights for decision-makers.

He is committed to mentoring the next generation of healthcare professionals and has participated in programs to mentor Northwestern college students.

Monica Mittal
Dr. Monika Mittal has a PhD in Physics and over 15 years of experience working with large-scale scientific and enterprise data. She spent more than a decade as a Postdoctoral Researcher at CERN, where she contributed to advanced particle physics research associated with the Nobel Prize–winning discovery of the Higgs boson.
Read more
At CERN, her work focused on extracting insights from massive experimental datasets using advanced statistical and computational techniques for the precise measurement of Vector Boson Fusion at CMS and ATLAS experiment. She also led development efforts at the detector edge.
Transitioning from fundamental science to industry, Monika now applies her expertise in machine learning, predictive modeling, and data-driven decision systems to solve complex business problems. She specializes in working with regulatory and compliance-related data, leveraging large language models (LLMs), agentic AI, and RAG systems to automate analysis, extract knowledge from complex documents, and support intelligent decision-making. Monika is passionate about building scalable AI solutions that bridge scientific methodology with real-world business needs, transforming complex data into actionable insights and impactful applications.

Zachary Fox
Zach Fox is a Senior Analyst at Analysis Group in Chicago, where he applies economic theory and data science methods to solve complex business disputes.
