Carol Kiam Assato
Master’s Student, Illinois State University
Skill Set
- Microbiology (Bacterial & Yeast Analysis)
- Pennycress Breeding
- CRISPR Gene Editing
Expected Graduation
December 2023
Carol Kiam Assato was born and raised in Sao Paulo, Brazil. Carol completed her BS in molecular biology at Alcorn State University. She decided to join IPREFER CoPd John Sedbrook’s lab because she wanted to collaborate on making a sustainable impact in the world.
Before coming to ISU, Carol worked as a microbiologist doing bacterial and yeast analysis for three years. Although it was a different area, Carol gained a lot of experience having GLP, following SOPs, meeting TATs, and working independently. Since joining Dr. Sedbrook’s lab, she has collaborated closely with fellow IPREFER grad student Liza Gautam, mainly working with pennycress. As of now, Carol is focused on breeding lines, moving lines forward, and of course, using CRISPR gene editing to integrate the desired traits.
