Research InterestsResearch in the Swift lab is directed toward gaining a more detailed understanding of the mechanisms by which molecular crystals nucleate and grow. Most of the projects in this research area are quite interdisciplinary - meaning students will be expected to gain experience in at least a few different areas of chemistry including x-ray crystallography, atomic force microscopy (AFM), organic synthesis, and computational modeling. 
1.  Crystal Growth in Human Disease/Biomineralization
Cholesterol is a major constituent of human gallstones and arterial plaques.  Using in situ AFM, the real-time crystal growth of this important material can be elucidated.  Unprecedented details on the crystal's surface structure, growth rates and growth mechanisms are obtained in model bile solutions and in a variety of conventional organic solvents.  The nucleating (or anti-nucleating) influence of assorted impurities is also a subject of interest.
Uric Acid is a known component of human kidney stones and gouty deposits.  Fundamental AFM studies provide insight into how solution parameters (e.g. pH, supersaturation, impurities) affect crystal growth kinetics and/or mechanisms.  Complementary experiments using microspectrometry are used to elucidate recognition events between the crystal surface and designer impurities. 
2.  Crystal Growth With 2D- and 3D- Templates
Crystal Growth in Gels has been used for over a century as a method for growing metals and inorganic crystals, but the details of nucleation and growth within these media are not well understood on the molecular-level.  Our fundamental studies seek to understand how intermolecular interactions between the gel and crystal can be exploited to access unusual crystal morphologies, affect chiral separations and/or template the growth of new polymorphic phases. 
Self Assembled Monolayers can be very effective templates for the growth of a variety of moleuclar crystals.  The rational design and testing of a series of SAMs with controlled functionality and lattice spacing, provides a means to construct a combinatorial library of 2D templates for molecular crystal growth studies. 
In the NewsCrystal Clear Persuasion
The Department of Chemistry's Jennifer Swift is launching a war on crystals that cause gallstones or kidney stones, hoping to slow down their growth and understand what makes them tick. June 1, 2005
