As laser pioneer Herwig Kogelnik said in an interview, “[breakthroughs] seem to be happening at the interface between disciplines.” Indeed, the precursor to the laser—the maser—was itself born outside the realm of optics, in the field of microwave engineering. Such cross-pollination can happen on a smaller scale too, in a university or industrial research lab. Regardless of whether you choose to pursue a career in academia or industry after you finish your Ph.D., chances are that you’ll need a diverse set of skills to do your job well.

I chose to step outside of academia but to remain in research: I joined the corporate research lab of a large engineering company in Switzerland called ABB. Our ultimate goal was to make a profit rather than to “merely” enrich our scientific knowledge base—quite a departure from the philosophy of my professors in graduate school. The research topic was also foreign to me, as it was more closely linked to plasma physics than optics. However, my knowledge of optical technologies helped me to understand this unfamiliar subject area, and I found it both enlightening and satisfying to dig into a vast new field. My multidisciplinary team regarded problems as challenges that we could attack from multiple angles due to our varied backgrounds.

In today’s competitive environment, companies are realizing the necessity of hiring people with a multitude of skills. This diversity ultimately benefits the organization as a whole. Studies have shown that multidisciplinary teams provide three times more high-quality solutions to problems than non-diverse ones.

For a diverse team to work together effectively, its members must have “soft” skills, such as the ability to promote trust, respect each other and exhibit kindness, in addition to their core capabilities. Just as with technical abilities, these proficiencies will vary from person to person, and a team benefits from having a variety of personalities with complementary skills.

In addition to encouraging diversity in the teams with whom you work, you should cultivate it in yourself by developing a well-rounded portfolio of personal and professional skills. Here are a few suggestions for how to do that:

• Figure out what your strengths and weaknesses are. This will help you to recognize what you have to offer a group and identify areas for improvement.
• Get involved. I helped to set up the first OSA student chapter in Germany in 2007 and the IONS network shortly thereafter. These activities were a fun, helpful way to make new connections.
• Truly listen to others, regardless of their place in the hierarchy. Quieting your own thinking allows you to really learn from someone else. It also shows the other person that his or her thoughts are appreciated.
• Fully immerse yourself in different cultures by occasionally traveling alone. This independence will give you the confidence you need to actively seek new challenges and experiences.
• Read about other disciplines and attend conference sessions outside your field. This will help you to cultivate new interests and find different applications for your work.

Diversifying my skills and knowledge has opened many doors for me. I encourage you to do the same and keep an open mind about the direction your career path may take. Who knows—maybe we’ll bump into each other at a conference where we both learn something new.

Balint Horvath ( received his Ph.D. in physics from the Max-Planck-Institute of Quantum Optics in 2009. Shortly afterwards he joined ABB Switzerland Ltd's Corporate Research Lab, where he conducted research related to switchgear devices. Recently, he has joined another energy company's R&D program in a lower management position.
