Most engineers I knew in my MBA program went into finance. It’s not too surprising: you need to be analytical and highly skilled in Excel. Our academic cousins in Physics were applying differential equations at Long Term Capital Management (the case study for “math gone wrong”) and prior to the housing crisis Wall Street was even hiring engineers without their MBAs (article). But there is a difference between finance for the Street and the finance used to drive operations. We’ll focus on the latter and how it ties into our fundamental building block for ChE: The Material & Energy Balance.
