Seila Selimovic, elected to Sigma Xi in 2004, has used microfluidics technology to investigate tissue regeneration and particle organization. She hopes gaining a better understanding of macromolecules and cells can lead to improved medical diagnostics and treatments. I received my PhD in condensed matter physics from Brandeis University in Waltham, Massachusetts. I decided to explore soft matter in graduate school and was assigned to a project involving microfluidics. For my dissertation research, I studied the phase behavior of proteins and polymers using microfluidics. Microfluidic technologies are a highly interdisciplinary field, combining physics, chemistry, biology, and various engineering disciplines. These microscale technologies are used to control minuscule amounts of fluids and suspensions inside a miniaturized system. Microfluidic devices are often compared to computer chips, but with liquids and particles being pushed around instead of electrons.
