At conferences, I often run into young women in early technical careers who are hungry for advice.

As a scientist, I am delighted to oblige. Seeing more women in technology careers helps young women visualize themselves in those positions. But I find the questions seldom involve matters of science or engineering.

No. Undergrads, graduate students and women working their first jobs after college want to know:

"What should I wear?" "How should keep my hair?" "How do I fit in with the guys?"

And the most meaningful question:

"How do you remain successful while having a husband and child?"

Debating clothes and hair may seem superficial, but it reveals the challenges women face attaining a technology career and keeping one.

When a young physicist asks me what to wear to work, she's not asking for fall fashion trends. She's actually asking: "How do I fit in at my office, where everyone else is a man?" The questions expose a sense of not belonging.

The death this year of a fellow aerospace engineer, Yvonne Brill, captured this tension. Brill was a rocket scientist, one of a very few female members of the National Academy of Engineering, and had been awarded the National Medal of Technology and Innovation. She faced the work-life balance dilemma (starting back in the 1960s, no less), and completely mastered it.

But when she died in March, The New York Times led her obituary with: "She made a mean beef stroganoff, followed her husband from job-to-job and took eight years off from work to raise three children."

The story followed with a revelation that Brill also invented rocket-propulsion systems that put communications satellites into orbit.

She had been an inspiration to many. I and many of my fellow technologists were disappointed in the implication that her highest life accomplishment was domesticity.

Thankfully, we were not alone. Others - both men and women - were so outraged that the newspaper edited and republished the piece. The reaction to the obituary shows that our society is moving in the right direction. But we're not there just yet.

I never waste an opportunity to persuade a young woman to stay on the tech track, especially in male-dominated areas such as engineering. Feeding the pipeline with smart, young girls is an important challenge. But retaining them has been just as difficult.

Research published in Psychology of Women Quarterly early this year found 10th-grade girls earn similar grades in the same math and science classes as 10th-grade boys, but those girls tend to believe that their abilities are not as strong as their male counterparts.

Another study in that same issue found that having women college professors positively affected female students' attitudes about a STEM career path.

I see this at work and when I attend those networking events. Women, more than men, in my experience, look around at a workplace where they are outnumbered and question whether they even belong there.

That is why women thriving in technical-career fields, especially those of us who have attained leadership positions, must dedicate more time to "lean in," as Facebook executive Sheryl Sandberg has been advocating.

Arguably the most influential woman in technology this year, Sandberg and her best-selling book have stirred candid discussions and important debates about gender in the workplace. This public conversation is possible only because of her willingness to be visible.

The educational system will continue doing the job of preparing women and men to solve our world's toughest technical challenges. What must increase is the participation, visibility and outreach of women who have made it.

We should be the ones inspiring and socializing girls into science and math fields. We might be busy trying to balance our own successful career schedules, but we must make it a priority to speak to young women engineers and scientists, encouraging them to stick with it. We must choose to be seen - and heard.

When women hear and see other women in technology, they will know not just what to wear and how to keep their hair. They will know how to pursue their calling as scientists and engineers in male-dominated workplaces, and that it's possible, and natural, to live a balanced life.
