Describe your role with the Mission to Hubble.

It's my job to help train the astronaut crew that will perform the spacewalks required to repair the telescope. Training takes place here at Goddard Space Flight Center. My team demonstrates flight hardware and tools to the astronauts. Training also takes place at a large pool at NASA's Johnson Space Center. Practicing repairs underwater simulates the (microgravity) environment of space.

What should people know about Hubble?

I want people to know that Hubble is a success because of several factors. It's successful because of the hard work of a lot of people working toward a common goal and because of their belief in the benefits that Hubble provides to the public. NASA cannot achieve its successes without teamwork and dedication of a very diverse workforce.

Hubble stirs the public's imagination and feeds our natural desire to understand our universe.

How did you become interested in science? How did that interest grow into a career?

I always enjoyed science and math in school. That was probably a driver more than anything, as nobody in my family is in engineering or science. I guess I just enjoyed taking things apart to see how they worked. Engineering sounded like a good fit.

What advice would you give to students who are thinking about a career in science?

The main advice is the same I give to my kids. Do something you have a passion for and enjoy because it will be something you do for a large part of your life. Don't worry about specific jobs. Different opportunities will always come along that will make you change your mind. What you want to do today will not likely be the exact same thing you do tomorrow.

Science jobs are fun and challenging. They put you in touch with new technologies and experiences that are always exciting.
