William McLaughlin, PhD

Research interests

William McLaughlin, PhD, is an associate professor of computational biology in the Department of Medical Education. He completed graduate work in the joint program in computational biochemistry at Rutgers, the State University of New Jersey/University of Medicine and Dentistry of New Jersey. His postdoctoral training was done at the University of California, San Diego, where he was a Ruth L. Kirschstein National Research Service Award Fellow and a member of the Center of Theoretical Biological Physics. Dr. McLaughlin is currently a contributing member of the Protein Society, The International Society for Computational Biology, American Medical Informatics Association and the American Chemical Society. His research interests include the energetics of macromolecular association (protein/DNA and protein/protein), protein/drug interactions, high throughput molecular biological experiments, data mining and drug repositioning.

Dr. McLaughlin’s laboratory aims to help bring together advances in biomedical science regarding our knowledge of proteins in living systems. Descriptions of the biological functions of protein are being assembled. Connections are made between protein functions and the characteristics of proteins with regard to their primary amino acid sequences and their three-dimensional structures.

The laboratory is developing online search tools which connect proteins with their biological functions, disease associations, and their interactions with medications. One application is to identify known and putative medications for a queried disease. The laboratory is applying the search tools to identify and prioritize medications which may be used to treat dementia with the goal of improving clinical outcomes.

The laboratory’s research is supported in part by the Marquardt Foundation for research to advance the treatments for Alzheimer’s disease.

Student research opportunities

Members of Dr. McLaughlin’s laboratory study the large scale elucidation of protein structure to function relationships. Connections between health conditions, proteins and medications are made with attention paid to their quality and completeness. Query tools are being developed which enable the retrieval of known and putative therapeutics for a queried disease. Predictions are made regarding the functional and phenotypic associations of proteins. Also, accuracy estimates of protein structural models are being derived. To better enable individualized care for those with dementia, associations between drug treatments and genetic variations are being identified. Students gain training in the fields of structural bioinformatics, pharmacogenomics and translational bioinformatics.
