Her expertise is in nucleic acid extraction, molecular testing, and assay development for formalin-fixed, paraffin-embedded tissues obtained from autopsy and biopsy specimens. Estetter has been an author of several peer-reviewed publications for her molecular work on Zika virus and SARS-CoV-2.

Estetter received her Bachelor of Science in Microbiology at Texas State University in 2010. She completed a Master of Science in Biology (focus on microbiology) in 2012. Her research titled "The effect of bacteriophage T4 and PB1 infection with tobramycin on the survival of Escherichia coli and Pseudomonas aeruginosa biofilms"​ earned her an award in the Medical Microbiology Poster category at the 2012 Texas Branch American Society for Microbiology meeting and was published in MDPI Viruses.

After completing her M.S. in Biology, Estetter continued her education at Texas State with a second Bachelor of Science in Clinical Laboratory Science (CLS). During her final year in the CLS program, she was awarded a position in the APHL/CDC Emerging Infectious Diseases Fellowship.
