Dr. Karen Twietmeyer

I'm the Principal Optical Engineer at QD Vision, a startup in Lexington, Massachusetts. My company makes quantum dots, and we were the first company to put the beautiful colors of quantum dots into TVs (made by Sony) that are sold around the world and have won many prizes! I work on optical designs to make quantum dot displays more efficient, and I design instruments to measure the quantum dots in production before they are put into the TVs. My degrees are a BS in electrical engineering from MIT, an MS in electro optics from Tufts, and a PhD in optical physics from the University of Arizona. I started out as an electrical engineer but I totally fell in love with optics and decided to become an optical engineer! It is a totally amazing field! My favorite past projects are designing a polarization based imaging laser ophthalmoscope for my PhD dissertation (it has a long name, but basically it's a new kind of instrument to detect eye diseases), and working on a laser instrument to detect cervical cancer at a startup company.
