Okay, let’s tackle this. So Thomas Yi has 39 years of experience leading the Power Systems Branch at NASA, which is a high-level position. His education from top-tier universities like Johns Hopkins and UC Berkeley adds prestige. Skills like biomedical engineering and design are in demand. Location is Ellicott City, MD, which is near Washington D.C. and a hub for government contractors. Biomedical engineers with his level of experience, especially in government contracting, typically charge higher rates. Maybe around $200–$300 per hour? But considering his leadership role and academic background, maybe higher. Some top biomedical engineers can charge $400+. Let’s check averages. Biomedical engineers with his experience might average $250–$350. So I’ll estimate around $275}
