Close Up
  • Describe what you do in your current work situation.
    I provide consulting services to the electric utility industry. My areas of expertise are in generation planning and fuels. I oversee analysis that is conducted, write reports and testimony, and serve as an expert witness.
  • Why did you choose engineering?
    I really liked math and I wanted to apply my skills to solve problems.
  • Where did you go to school and what degree(s) do you have?
    University of Virginia, B.S. Applied Mathematics, minor - electrical engineering University of North Carolina at Charlotte - M.B.A.
  • What kinds of activities have typically been part of your work?
    In the early years, I ran two types of simulation models - production costing and capacity expansion. Production costing models simulate the operation of the existing fleet of generation units. Capacity expansion models look into the future and project the types of generation units that will optimally serve customer needs over the planning horizon (typically 20 years).
  • What do you like best about being an engineer?
    I love to solve problems. I like to know that my work is making a difference. At the very foundation, my job is simple - I help keep the lights on.
  • Which of your career accomplishments are you proudest of?
    I helped several utilities get the certificates of public convenience and necessity that they need to build power plants to serve customer needs. I was involved as an expert witness in that process. I am also a writer and an advocate for women. I am very proud of my best-selling and award winning book - Her Story: A Timeline of the Women Who Changed America.
  • What challenges have you met and conquered in your pursuit of an engineering career?
    Life and work rarely goes as one predicts. I have overcome bad bosses, employment cultural fits that did not work for me, and work environments that did not suit me.
  • Please tell us a little about your family.
    I am married and we have two cats.
  • What are your short-term (1-2 years) and long-term (10+ years) goals?
    To change the perception of women around the world. I am now an advocate for women.
  • What (or who) had/has the greatest influence on your life choices?
    My parents. The Society of Women Engineers and the outreach program - A Great Women in Engineering and Science essay contest. That led to my nominations of many women for national awards and most of my books.
  • What advice would you give to a young woman considering a career in engineering?
    YOU CAN DO IT!! The keys are passion, determination, and persistence. Don't let anyone tell you that women don't or you can't. You can.
  • Any other stories or comments you would like to share with EngineerGirl visitors?
    I love to solve problems. I like to know that my work is making a difference. At the very foundation, my job is simple - I help keep the lights on.
  • Describe something about your life outside of work: your hobbies, or perhaps a favorite book.
    I still play singles tennis and really enjoy it. I also love to do needlework, particularly counted cross stitch and needlepoint.

I am proud to work in the electric utility industry - helping to provide electricity to power our world. I serve as a consultant and provide expert witness services in the areas of planning for power plants and rates. For over 30 years, I have worked to get more women in the engineering field. An engineering career is so meaningful - engineers make the world work.

    I am currently taking a computer architecture and organization class for my undergraduate in Electrical Engineering. I am a sophomore and I am starting to get worried that maybe this is not the major for me. I do not know if it is the class or the professor that makes me feel this way. I love my circuits class and I enjoy my extra non-major/gen-ed classes. I was not so great in Digital Logic and Design either. Is Electrical Engineering something I really want or should I look into something ...

    Dear Hannah,  

    You ask a very important question (quite similar to one that an undergraduate in mechanical engineering asked me last week).  No, it is not important that you love every class that you take in engineering.  In fact, I ...

    I'm currently 20 and graduated high school in 2012. I've finally made the decision of going to college and I'm wanting to go for a bs in ee. Doing two years at a community college and then transferring over to a uni. Is this a good route to go? I'm not 100% positive that this is what I want to do and I am afraid of student loans being too much. what should I do? should I just go for a certificate to be an electrician or make the giant leap and do something greater and become an ee? Or maybe ...

    Yes, I highly encourage you to pursue the community college route on the way to your BS in EE.  Many students – in fact, about half – enroll in community college for the first two years of their engineering education.  It ...

    Hi, I am currently a senior in High School, about to apply to Universities and am very interested in Engineering. What is the business side of engineering? Do most industrial engineers work in the office? What exactly do engineers usually wear? Thanks for the help! [;

    Hello Kala,

     You have asked some excellent questions. Engineers always have to consider cost, time, and labor when they think about their projects. For example, in my work, helping to select the new power plant for an electric utility, ...
