Helen writes about her favorite topics, science and money, at her blog, creatively named www.ScienceAndMoney.com. With a Ph.D. in Materials Science and fifteen years of experience in semiconductor research, development, and manufacturing, she turns a critical eye to financial planning and investment analysis. She likes to challenge conventional assumptions and is generally skeptical of financial advice. Sometimes convention is correct, but arriving at the answer from an independent direction gives greater confidence that the solution is correct (or at least a local maximum). She lives with her life partner and their young son north of Boston. She is progressing through the Certified Financial Planning program at Boston University. Helen is also formerly a Captain, United States Air Force.
