Engineering physics major, Karen Vaughn, offered NSF and NDSEG Fellowships

Karen Vaughn, a graduating senior from Case Western Reserve University, faces a tough decision as a new graduate. Having received two major awards to support her graduate education at the University of California at Berkeley, Vaughn will have to decide between accepting the National Science Foundation Fellowship or the National Defense Science and Engineering Graduate Fellowship.

Vaughn came to the university as a transfer student from Grove City College in Pennsylvania. She says she chose Case Western Reserve for its opportunities to participate in undergraduate research projects and has spent the last two years working with physics professor Charles Rosenblatt’s research group on the study of liquid crystals.

The Rosenblatt group’s research project examined ways to control the liquid crystal orientation on a surface by controlling the “pre-tilt” angle, with the ultimate goal of achieving this on a pixel-by-pixel basis using ink-jet technology.

“If we are successful, we will be able to develop new types of switchable optical gratings for purposes of laser beam steering and optical communications,” said Rosenblatt.

For her senior capstone project, Vaughn designed a microelectrical mechanical system (MEMS) resonator and tested the use of silicon carbide as a potential material for the resonator. She worked on the research with Mehran Mehregany, Goodrich Professor of Engineering Innovation at the Case School of Engineering and one of the pioneers of MEMS research. She plans to continue that area of research when she heads to Berkeley in the fall where she will pursue her interests in MEMS and optoelectronics.

While engineering research takes up much of her time, Vaughn has found time to continue developing her skills as a fencer and participated in the Midwestern Conference Championship. She also spends her off-campus time snow skiing in winter and water skiing in summer and thinks the two sports might translate into surfing if she has a chance to try it during her studies not far from the Pacific Ocean.

Since childhood, Vaughn said never doubted she would go into the sciences.

“I grew up in a science-minded family,” she said, adding that her father is an engineer with several patents on inventions and an uncle is a chemist.

Having fun with her father, she recalls how he conducted an experiment in the kitchen using the car battery to show the Vaughn children how to create an electromagnet and another one growing bean seeds in different soil and amounts of water to track growth.
