Okay, let’s tackle this. So Stephanie has a mix of laboratory and non-laboratory skills, which affects her earning potential. Microbiologists and molecular biologists typically charge higher rates than those with only laboratory skills. Considering her skills and experience, I'll estimate her hourly rate to be around $75. This is slightly lower than the national average for microbiologists in the US, which is around $90–$120 per hour. However, her skills in training and time management also bring her rate down. Let’s assume she’s a junior or mid-level professional in this field, which would put her rate at the lower end of the spectrum.
