Okay, so Binaya has 48 years of experience in a relatively niche field like plant pathology. Considering the duration and depth of experience, I'd estimate his hourly rate to be on the lower side. Let's compare this to other professionals with similar experience. A Ph.D. holder with 20-30 years of experience in a field like plant pathology might charge $100-$200 per hour. However, Binaya's 48 years of experience push him into a higher range. Considering his location in Raleigh-Durham-Chapel Hill Area, which is a hub for academia and research, I'd estimate his rate to be around $100-$150 per hour. But given his extensive experience, I'll round up to $100 per hour.
