I am a mechanical engineer currently working for a global leading bearing manufacturer, NTN Bearing Corporation of America in Mount Prospect, IL. I have a BS and Master of Engineering in Mechanical Engineering from Old Dominium University in Norfolk, VA. In my free time I volunteer to teach ESL classes at the Vietnamese Association, north side of Chicago. I also like handcrafting; I create jewlery from polymer clay. What I enjoy most about my job is that I get to work on a variety of projects. I get to design bearings for various applications and industries such as construction, mining, automotive, aerospace, medical, etc. The projects are fairly complex and they require extensive research on the application and its operating conditions such as loads applied, temperature, lubrication conditions. As an engineer you have to account for all given conditions, but you also have to plan for the unexpected. Basically, you have to design with a worst case scenario in mind. While the word ”bearings” may not mean much to many, these pieces of machinery are quintessential for anything that rotates – from complex systems such as cars or planes to computers, printers or tiny medical devices such as the dental equipment. I was not born with a passion for engineering. Up until senior year of high-school I did not know what mechanical engineers do. The reason I chose to pursue a ME degree is because I liked the idea of studying an exact science. Unlike humanistic careers where you may have a million of good answers and interpretations, in engineering, particularly Math, 1+1 will always equal 2 and nobody has to agree or disagree about it. With that being said, I would like to encourage more young girls to pursue careers in the STEM field. I believe having a strong technical background will help develop your critical thinking skills which will ultimately help you succeed in any career you may later decide to follow.

    I am a licensed mechanical engineer, female engineer. But right now, several thoughts keep circling my mind. I even questioned myself why did I took up mechanical engineering. I badly need tons of motivation right now 'coz so far I'm not enjoying my profession. Am I in the right field?

    Dear Shinju Yumiko,
    My first job was biomedical engineer type job (my degree is in Mechanical Engineering) – I worked on IV sets. I didn’t like it because it wasn’t hands on. However, after working there & meeting a lot of people with different ...

    I must commend the awesome job you do, I appreciate it. I graduated as a petroleum engineer but I want to enroll in masters mechanical engineering. Am worried if I'll be able to cope since petroleum engineering is highly specialized while mechanical is very broad. Jason

    I looked up briefly at a petroleum engineering degree curriculum, and I noticed that while there are a few fairly specialized classes, the core of the curriculum is similar to that of a mechanical engineering degree: Calculus, I, II, Chemistry ...

    Hello, I am currently enrolled as a sophomore for the College of Engineering. I planned on focusing on Mechanical Engineering, but now I am not sure if this is the right major for me. What helped you decide to stay with engineering when it was difficult? What do you think is the most rewarding part? Thank you for your time.

    Not too long ago I was in your shoes. I was well in my 3rd semester of studying ME and things got pretty difficult. I had classmates dropping out or switching majors. It was very tempting; it is particularly tempting to give up if you are used ...
