Okay, let’s calculate this. So Maria has a Ph.D. in a field that’s not explicitly mentioned, but she has skills in research, public health, and statistics. She’s also worked in nonprofits and has management experience. Location is Baltimore, MD, which is a mid-sized city with a relatively lower cost of living. According to Glassdoor, a research scientist in Baltimore can earn around $80,000–$110,000 per year. Considering her Ph.D. and experience, I’d estimate her hourly rate to be around $40–$60. However, since she has strong skills in data analysis and public speaking, I’ll bump it up to $50–$70. Given the industry demand and her expertise, I’ll estimate her hourly rate to be around $60.
