Global Consortium
for Chemosensory Research

Participate in the GCCR studies

We are conducting world-wide scientific studies to assess the possible relationships between respiratory illness (e.g., COVID-19, influenza or the common cold) and their effects on smell & taste.

You can take two studies. A survey and a self-check with items that you can find in your home.

The GCCR will foster the advancement of chemosensory science at large, allowing the possibility to test larger samples of participants cross-culturally, strengthening the reliability and validity of chemosensory science across many domains.

Currently, the timely mission of the GCCR is to define and coordinate world-wide crowdsourced research to understand the reports of the chemosensory issues related to COVID-19. Subsequently, the establishment of this consortium.

In accomplishing this mission, the GCCR’s primary roles are to work cooperatively with its members to:
