[006] ‘MTSU On the Record’ explores biology in 3D with library grant funding

MURFREESBORO, Tenn. —Using digital technology to count fish and sponges and assess their differences is the topic on the next “MTSU On the Record” radio program. 

Host Gina Logue’s interview with Anna Grinath, an assistant professor of biology, will air from 9:30 to 10 p.m. Tuesday, July 17, and from 6 to 6:30 a.m. Sunday, July 22, on WMOT-FM Roots Radio 89.5 and

Grinath is one of two recipients of the 2018-2019 James E. Walker Library Digital Seed Grants. The stipends are allotted each year to faculty members who have imaginative ways to use technology to improve teaching methods.

For her project, Grinath will employ three-dimensional models of coral reef sponges and freshwater fish created on 3D printers in the library’s Makerspace area to explain population sampling and variation within populations.

“Oftentimes, we’re not going to be able to measure every single individual in a population,” Grinath said. “What we need to do is to collect a sample of individuals from a population, measure those and, then, we’ve got tools that allow us to make inferences about the entire population based on a sample.”

Variation within a population of creatures can be created by mutation of chromosomes, random mating and random fertilization, among other factors.
