Research: I engage students in two distinct types of research projects.  Both are concerned with different aspects of the role played by water in our lives.
1.  Volumetric Properties of Water Solutions. In our research group, we are interested in the volumetric properties of solutions.  To have a solution you need a solvent, say water, and a solute (what is dissolved in the solvent).  The molecular structure of both solute and solvent affect the way they interact with each other.  These interactions are important, among other reasons, because they influence the behavior of biological molecules (proteins, nucleic acids, etc.).  We study solute-solvent interactions by measuring how the volume of the solution changes as one changes the pressure and the concentration.  The way the solution behaves as a function of concentration and pressure provides information about solute-solvent interactions and allows us to tell a story about why biological macromolecules behave the way they do in water.

2.  Appropriate Water Purification Interventions. Lack of access to potable water kills about 4000 children a day worldwide.  For that reason, a great deal of attention is being paid to simple devices that allow people to purify water at home.  It is an approach known as “Household Water Treatment and Storage” (HWTS).  We use one of those devices and implement projects in rural communities in the Dominican Republic.  Research in this area can be the testing of HWTS devices in the lab, which may be accompanied by a field experience.

Bio: In graduate school, I studied the physical chemistry of crossed molecular beams of noble gases.  In industry, at Bell Labs, I worked on R&D of silicon semiconductor device (integrated circuit) manufacturing.  At Rollins, I have become interested in the development of new experiments for undergraduates.  I have worked with biology students and faculty in investigations of the bisphenol family of chemicals known to behave as endocrine disruptors.  Each year I recreate a historic and very tall water barometer experiment with both science and non-science students.  I recently developed an advanced nuclear magnetic resonance (NMR) course for upper class students.  Other interests include running, biking to work, making liquid nitrogen ice cream, and playing guitar with faculty and students in the rock band Broken Violets.

Research: Consumers use products made from the chemical and pharmaceutical industries daily.  Environmental and economic pressures with current synthetic methods create a need for the development of new ways to make molecules.  My research focuses on the use of transition-metal catalysts for organic transformations.  The goal is to find a different route to making a target molecule that requires less time, energy, reagents, and waste produced.  Current work focuses on the synthesis of iron complexes with N-heterocyclic carbene ligands.  The iron complexes are then screened for different types of reactivity including additions, aromatic substitutions, reductions and oxidations.

Research: The advancement of biomaterials research has become more significant in recent years as the need for biocompatible, bioselective medical devices has grown. As surfaces of biomedical devices are often the first part of the device that interacts with the biological host, it is crucial to develop a method that is able to control and modify these surface properties. One theme in the Park research group is the development of bioselective gold nanocomposites that can serve as a platform for a new kind of cancer treatment. Gold nanoparticles are of special interest due to their unique ability to effectively convert light energy into the form of heat and potentially act as delivery vehicles of anti-cancer therapeutics to solid tumor sites. My lab will use tools in analytical and photochemistry to achieve the following objectives: (1) develop a photografting method that allows for the attachment of nearly any biomolecule onto gold nanoparticle surfaces, and (2) produce biocompatible, highly selective nano-vehicles for diagnostics and therapeutics. Other projects in the Park research group include the fabrication of thin films on a wide selection of surfaces (e.g., gold, silicon) using nano- and/or polymeric materials for biomedical applications.

Research: Fragment-Based Ligand Discovery (FBLD) is a modern technique for the discovery of chemical matter for challenging targets in drug discovery and basic research. My research interests are in the area of applying FBLD in basic cancer research. My laboratory consists of two major projects: 1. The synthesis of improved fragment molecules to establish a library specifically designed for the identification and rapid optimization of protein-protein interaction inhibitors. This project consists of synthesizing (3-5 steps) small libraries of multivariate molecules. 2. The fragment-based development of inhibitors of the glycolysis pathway, to take advantage of the Warburg Effect. This project will consist of screening fragments against enzymes in the glycolysis pathway, identification of fragment hits, and optimization of the fragments into potential lead molecules.

Research: The first cancer-causing virus was discovered ~50 years ago, but we still have no vaccine or cure for it.  Together with my students, we are currently exploring the interplay between cancer-causing viruses and infected human cells.  We identified and are currently exploring thousands of gene transcripts that are regulated by human and viral microRNAs: tiny non-coding RNAs that base pair with specific messenger RNAs to down-regulate them. It is our hope that our research will contribute to a greater understanding of how the virus causes cancer and thereby pinpoint good targets for future anti-viral drug development.  The Riley Lab’s projects are interdisciplinary, combining foundational elements of biochemistry, bioinformatics, molecular biology, cell biology, and genetics.

Bio: Pseudoscience and the spread of disinformation has a profound effect on the shaping of communities and individuals. My current interests lie in improving science literacy within the liberal arts framework. Courses that exemplify this objective include Clickbait Chemistry, a course on analyzing scientific news found online and in social media, and Crime Scene Chemistry, a course exploring the chemical principles surrounding forensic science. The ability of students to critically examine scientific phenomena and to apply topics in chemistry to real-world applications is a primary goal. I also have an interest in general chemistry education, and development of demonstrations and relatable examples that can be used to illustrate and explore various chemical principles.
