Okay, let’s tackle this. So Iain has a strong educational background in biochemistry and chemistry, which is great. Skills like pharmacokinetics, drug metabolism, and drug discovery are in demand, especially in the pharmaceutical industry. Location is Cambridge, MA, which is a hub for biotech and pharmaceutical companies. According to Glassdoor, a biochemist with similar skills in the US can earn around $80,000–$120,000 per year. Considering the cost of living in Cambridge, I’ll estimate his hourly rate to be around $125. This is slightly lower than the average salary range, but it's still a competitive rate for someone with his expertise and experience.
