The Genetics of Taste Lab

Crowdsourcing and Citizen Science

"The Science of Sour Study" opens November 21! 

The community-based Genetics of Taste Lab at the Denver Museum of Nature & Science will be home to another groundbreaking taste study! Citizen scientists will gather population data by crowdsourcing Museum visitors on just how humans experience sour taste.

Are all sours the same?

There are several different sours that people encounter in our daily life. Vinegar is mainly acetic acid while our lemons and limes contain citric acid. But does our tongue know the difference? We are investigating a few different sours and want to see how people vary in their taste. Some people love sour while others hate it! The truth is, sour isn't well understood by scientists yet. We don't know exactly how our tongue detects it, which genes are responsible for it, or if the variations in our taste are due to our genetics. So whether you love it or hate it, come taste the different sours and help science!

To participate, stop by the Lab on the second floor of Expedition Health to check on availability, or make an appointment by emailing a week ahead of your visit. Our goal is to enroll 1,000 people over the course of the nine-month study and the experience takes about 30 minutes. You will rate several sour solutions, answer questions about yourself related to your sense of taste, give a cheek swab so scientists can see what variations there are in your taste genes, and list how everyone is related (genetically or not) in your group. Everyone will leave with a thank-you packet to take home. We highly encourage friends and families to participate.

Community Participation: Research & Educational Goals

The Genetics of Taste Lab is a unique venue for both citizen science AND crowdsourcing health data.

  • We connect our community to research that is relevant to their lives.
  • We conduct research to answer real public health questions and publish in peer-reviewed scientific journals.


Free with Museum admission, we look forward to seeing you soon in the Genetics of Taste Lab! 

This study is led by Nicole Garneau, PhD ( is made possible by the Science Education Partnership Award program at the National Institutes of Health.

To become a citizen scientist, contact our volunteer services office at 303.370.6419 or visit

This research experience is free with Museum admission, takes about 30 minutes, and is subject to the availability of our citizen-scientists working in the lab that day.  

This lab was originally funded by a Science Education Partnership Award from the National Institute of Health (Award #R25RR025066)

Be a part of our Citizen Science Team

Our Citizen Scientists are volunteers that donate their time to conducting real and authentic human genetics studies in the areas of taste and health.

What do our citizen scientists enjoy most about working in the community-based Genetics of Taste Lab?

  • Interactions with peers
  • The opportunity to work in a scientific lab
  • Learning new things
  • Contributing to something of value

Not surprisingly, the majority of citizen scientists and exhibit guides bring both a passion for science and relevant training and professional experiences to their positions at the museum.

Be a part of our research team!

Volunteer sitizen scientists support the community-based Genetics of Taste Lab by collecting data from Museum guests during enrollments, processing and preparing DNA samples, sequencing DNA and entering data into our database.

One 4.5-hour shift per week, 8:30 a.m.-1:00 p.m. or 12:30 p.m.-5:00 p.m.

Minimum Commitment:
All citizen scientists begin their one year commitment by volunteering for a minimum of 6 weeks in Expedition Health as an Exhibit Guide. Following this training, volunteers may elect to apply for transition into the Genetics of Taste Lab as a citizen scientist.

Age Requirement:
Available to individual applicants 16 and older.  Volunteers must be 18 and older to enroll guests in the Genetics of Taste research study.

To apply: Please complete our Adult Volunteer Application and mail to:
Volunteer Program
Denver Museum of Nature & Science
2001 Colorado Blvd.
Denver, CO 80205-5798

Please remember that volunteer placement is a selective process and not all applicants are accepted into the program. The Museum reserves the right to place volunteers in the area staff feels is best suited to the applicant's skills and the needs of the Museum.

Community Partnerships & Internships

Genetics of Taste Research Partnerships

Check out our incredible team (on the right of the page). So much of our outreach and research could not be done without the help of these awesome volunteers both in the Museum and externally. 

Teen Science Scholars Program

The scientists and curators at the Denver Museum of Nature & Science strongly support the Teen Science Scholars program. Funded by individual donors and foundations, the program gives local high school students the opporunity to gain hands-on experience via a paid summer intership.

For more information visit the Teen Science Scholars Webpage.

University of Colorado Anschutz Medical Campus

We are lucky to have many established partnerships with the University of Colorado Anschutz Medical Campus, and through these partnerships there are opporuntities for stduents and interns.

*please note, the article incorrectly identifies Museum guests that participated in the research study as "citizen scientists." This term has a very specific meaning representing volunteers that are trained to collect, prepare and process, and help analyze data.
