Research/Professional Interests

Dr. Reif’s research interests are split between two major fields, cell analysis (bioanalytical chemistry) and RNA aptamer design and fabrication.  He is interested in designing new microfluidic devices designed to analyze mammalian cell samples by fluorescence microscopy and using these devices to study complex cellular processes such as (but not limited to) apoptosis.  One of the current projects in his lab focuses on the design and fabrication of a microfluidic device that incorporates glass surfaces on the top and bottom of a microfluidic channel but a gas-permeable polymer (PDMS) on the sides.  This device will potentially be compatible with both standard and inverted confocal microscopes while maintaining the health of the cells within the device during long-term analyses.

Dr. Reif is also interested in discovering new RNA aptamers that can be incorporated into RNA nanoparticles for a number of applications. He is currently working alongside Dr. Streu’s research group to design new RNA aptamers that bind drug molecules or protein targets using a technique called Systematic Evolution of Ligands by Exponential Enrichment (SELEX).  These RNA aptamers could be used for a variety of purposes including the design of therapeutic RNA nanoparticles, studying cell signaling, and/or influencing protein expression.  He is also interested in how RNA aptamers interact with large molecules such as cellular receptors or small molecular targets such as fluorogenic dyes.
