I am a retired engineer with a PhD in Engineering Science (mostly exotic math) together with a Masters in Statistics. I currently manage my website www.superchargeretirementincome.com, where I use my math background to select high-return, low-volatility investments. I also love teaching so I also provide a number of tutorials about all aspects of investing. I am an avid reader and have read just about every book I could find on the stock market. I am still learning so I welcome comments and suggestions. Over the years I have learned that there is no “holy grail”; you cannot receive a good return without taking risks. However, you can choose your investments to reduce risks and those are the kind of investments I like to make. Although financial markets are my passion, engineering is my profession. I have spent the last 30+ years as a program manager at a large aerospace company, working on improving defenses for our U.S. Army customers.
