How to Access the Bionutrition Unit

All studies require IRB and CHPS approval before CHPS services can be provided. To utilize CHPS resources, please contact the appropriate CHPS Core Director for a startup meeting prior to scheduling research subjects.

  • Please contact Debra Cahn or Erin Donaldson prior to the start of the study to discuss nutrition services needed, scheduling, and communication for visits/encounters. CHPS Bionutrition staff will work with study team members to determine the best approaches for gathering the necessary research data for a particular study.
  • Specific registration and scheduling details will be discussed during the start-up meeting.
  • Please contact John Krall, Administrative Director - 267-425-1790 or krallj [at] - for cost of core services.
