Welcome to the MacIntosh Lab @ Iowa State University. Our lab works on a variety of things, mostly centered around the two big questions described below (look for more details in Projects and Publications). Gustavo also dedicates a significant effort to increase equity and inclusion in STEM (see EDI page).

How do eukaryotic cells recycle ribosomes?

We want to know how cells transport ribosomes to the vacuole or lysosome, and the ribonucleases and other enzymes associated with the RNA salvage pathway.

What are the molecular bases of compatible and incompatible interactions between plants and insects?

We try to understand what are the mechanisms that plants (mainly soybean) use as defense against aphids, and the strategies used by aphids to avoid these defenses.

We support the Changing Cultures and Climate NAASC/ASPB Initiative
