Thanks for asking. I've been doing mostly engineering: built nuclear submarines for the Navy, operated the reactor plant in subs, integrated payloads for the Shuttle and Space Station in NASA, design and test satellite systems, especially power generation and distribution, some small aircraft research, about a year of superfund site environmental remediation, LOTS of computer hardware and networking, some telecom voice recognition hardware/systems work, taught some tech courses at Johns Hopkins, etc. I was self-employed through about half of that time. Now, I'm ready to move to more intense projects, especially where I can integrate research across disciplines to solve problems.
I have a long list of reasons for pursuing a new Ph.D. The chief reasons, I think, is that it will update my knowledge and lend some credibility to future endeavors. It should segue into research and application opportunities. And, a strong secondary reason is because I wasn't focused very well on college the first couple of times. Now, I can be totally dedicated.
Thanks, again.
