Research Directions

We develop and use molecular simulation, computational chemistry, and bioinformatics techniques in a variety of projects.

 


 

Rare Earth Elements in Solution

 

The separation and purification of rare earth elements is necessary to ensure the supply chain of these critical elements. We predict and resolve the molecular structures of lanthanide-ligand complexes in solution, in the context of rare earth element solvent, or liquid-liquid, extraction. Resolving the molecular structures of lanthanide-ligand complexes in solution is also relevant for medical contrast agents, single molecule magnets, and luminescent molecules.

Rare Earth Elements in Confinement

 

Rare earth elements, mostly lanthanum, is used to increase the stability of faujasite-based fluid catalytic cracking catalysts, which are key in the refining of crude oil. We study the coordination of rare earth elements in zeolitic confinement, and how that affects that stability and lifetime of zeolites.

 


 

Thioester-active enzymes

 

Fatty acid and polyketide synthesis enzymes are essential for the biological production of components in foods, insecticides, fungicides, antibiotics, and other chemicals. We build and maintain the ThYme database, which contains most known sequences and structures of enzymes that act on thioesters, classified by sequence similarity into families.

 

Resource: The thioester-active enzyme (ThYme) database. Our group, working with our collaborators, will launch new, updated version of the ThYme database, based at the University of Nevada, Reno.
