Computational Chemical and Structural Biology
About Meiler Lab
Research in our laboratory seeks to fuse computational and experimental efforts to investigate proteins, the fundamental molecules of biology, and their interactions with small molecule substrates, therapeutics, or probes. We develop computational methods with three major ambitions in mind.
A) To enable protein structure elucidation of membrane proteins the primary target of most therapeutics and large macromolecular complexes such as viruses;
B) Design proteins with novel structure and/or function to explore novel approaches to protein therapeutics and deepen our understanding of protein folding pathways.
C) Understand the relation between chemical structure and biological activity quantitatively in order to design more efficient and more specific drugs.
Crucial for our success is the experimental validation of our computational approaches which we pursue in our laboratory or in collaboration with other scientists.
Current research applications focus on new approaches to a) drug and probe development for neurodegenerative disorders and diseases including Schizophrenia, Alzheimer's, and Parkinson's, b) understanding the structural determinants of antidepressant binding to neurotransmitter transporters, c) cardiac arrhythmia as caused by the complex interplay of potassium channel regulation and drug interactions, d) multidrug resistance in cancer and bacterial cells related to multidrug transporter proteins, and e) structural basis of viral infections and antibody activity.
The BioChemical Library version 3.0 is available for download on meilerlab.org. This release features our suite of cheminformatics and QSAR applications, along with new and improved extensions to bioinformatics applications, including JUFO9D, membrane-folding protocols, and SAXS simulation.
User-interface improvements include a friendlier command line interface that offers suggestions whenever options are mistyped, and earier to read help dialogues (and many more of them!),

The 3 Minute Thesis competition sponsored by the Vanderbilt Graduate Student Council challenged graduate students in all fields across campus to present their thesis in only 3 minutes to a diverse audience. Students were challenged to present their research topic, explain how the research is conducted, and identify what impact it will have on the general or academic community. Elizabeth Nguyen, a graduate student in the Meiler Lab, received a co-first place prize for her presentation on "Progress Towards Unlocking the Treatment for Cognitive Impairment".
