CURRENT INTERESTS:

My research interests are in the area of statistical genetics and cover many subtopics within the area. I am most fascinated by the use of inheritance in humans to understand human disease, health and associated quantitative traits. This is a running theme and motivation throughout my work. I love the interface between science and statistics and find that the best statistical methods come from collaborations. My past work has included methods development in family-based association testing and genetics of gene expression studies. I have also worked over many other areas of statistical genetics from classical segregation studies to linkage and association studies. I am currently looking for a new area of methods work and am particularly interested in aspects of the human microbiome.

More details on my work, including teaching interests and experience can be found in my Curriculum Vitae.

PRIOR WORK AND BACKGROUND

I earned a Master of Statistics and Ph.D at North Carolina State University (NCSU) in the Department of Statistics. The latter degree included a concentration in statistical genetics and was under the guidance of Dr. Bruce S. Weir at NCSU and Dr. Normal L. Kaplan at the National Institutes of Environmental Health. My dissertation concerned methodological work initially concentrated on the use of linkage disequilibrium between alleles at two loci in order to localize disease susceptibility genes.  Methods were developed for samples of diseased individuals and their non-diseased siblings, a practical study design for diseases of late-onset (1, 2, 3). In addition, I developed methods that use linkage and linkage disequilibrium to locate quantitative trait loci (4).  These methods use families with parent and child information as well as families with only sibling information. This work was later extended to the use of general pedigrees (5). Papers relevant to this work follow:
  1. Monks SA, Kaplan NL, Weir BS (1998) A comparative study of sibship tests of linkage and/or association. Am J Hum Genet: 63:1507-1516. PMID: 9792878
  2. Monks SA, Martin ER, Umbach DM, Kaplan NL (1999) Two tests of association for a susceptibility locus for families of variable size: an example using two sampling strategies. Genetic Epidemiology 17: S655-S660. PMID: 10597509

My next area of research was inspired by collaborations with scientists at Rosetta Inpharmatics and Merck & Co. Eric Schadt was the major catalyst for these collaborations. Through the use of complementary information gained by applying statistical genetics principles to gene expression studies, our work aimed to enhance the ability to dissect complex interacting pathways that lead to disease susceptibility (6, 9). I developed algorithms and software for a variety of experimental designs that incorporated genetic variation, patterns of genetic inheritance, measures of relevant environmental influences and gene expression components, all facilitated by the latest in microarray technology. Work spanned over many organisms (7), including corn, mice and humans with my primary focus being on the latter (8). This work resulted in much success with publications in high profile journals and instigated my interest in multi-dimensional methods in statistics. Important publications follow:

I regularly work on collaborative projects with a preference to genetic studies, especially those involving family data. I think the best methodological work stems from real science and the associated experimental questions, designs and data. Collaborative publications follow and are separated into family based genetic studies, case-control genetic studies and other studies:
