Although my years at Irvine were very productive, I missed not doing experiments myself because of the many responsibilities associated with a faculty position: teaching courses, supervising graduate students, meetings, etc. After spending seven years at Irvine as Assistant and then Associate Professor, I decided to move to a non-academic position. I joined the Molecular Physics and Chemistry Section at the Jet Propulsion Laboratory in 1982. I had a smaller group – only a few postdoctoral fellows – but I also had the luxury of conducting experiments with my own hands, which I enjoyed very much.

And I acted when the actors didn’t show up. As the director, I knew all the lines and I took over more times than I wanted to. I didn’t know much about directing, but I was the only one willing to do it. Someone had looked around and said, “Who’s going to be the director?” I said, “I will.” I said that because I knew my way around the library. So I went to look for a book on how to direct a play. I found one called The Fundamentals of Play Directing and checked it out. I didn’t understand anything in it. It was all about form and mass and balance. I flipped through the book and there in Appendix A I discovered what to do on the first day of rehearsal. It said, “Read the play.” So I went to the first rehearsal very confidently and I said, “Okay, this is what we’re going to do. We’re going to read the play.” We did that. Now what? I hadn’t got to Appendix B. So I said, “Let’s read the play again.” That night I went back to the book and sort of figured out what to do from that point on.

Most pharmaceutical workshops were shut down during the great cultural revolution. Without manufacturing support, we had to extract herbs ourselves using household vats etc. The team worked very long hours every day including the weekends. Due to lack of proper equipment and ventilation, and long-term exposure to the organic solvents, some of my team members included myself started to show unhealthy symptoms. This, however, did not stop our efforts.

In every way at every turn, the question we ask ourselves is not what can we do, but what should we do?.”
