My work in the Department of Medicine is focused on enabling the process of biological discovery by developing high-speed, automated approaches for analyzing, searching, visualizing and understanding associations between omics data (genomics, metabolomics, transcriptomics, methylomics) and medical phenotypes. The techniques include developing and running computerized “pipelines” for large-scale association analysis as well as collecting and integrating a full spectrum of annotation for all genetic variants. Annotation includes basic information about each variant, allele frequencies in various populations, predictive scores for potential biological effects and customized “link-outs”, which send queries with specific information for each variant or gene, to public resources such dbSNP, GTEx, Roadmap Epigenome Browser, UCSC Genome Browser, GWAS Catalog.
The association analysis results (pValues, effect size, etc.) are stored in a database system called OASIS (Omics Analysis Search and Information System) which I developed for searching and filtering the results along with “on-demand, real-time” generation of boxplots to aid in the understanding of the effect size and the variability of the data. OASIS directly calculates linkage disequilibrium (LD) from the population being studied to identify multiple, unique association signals for a genomic region. The system is integrated with graphical tools (e.g. LocusZoom, Haploview) for quick LD visualizations. Additionally, “on-demand, real-time” multi-covariate analysis is available for customized analysis conditioned on other phenotypes and/or on multiple genomic variants.
OASIS currently allows University of Maryland investigators studying the Old Order Amish to query genetic associations for over 1200 cardiometabolic and other health-related traits for 6136 subjects. The fully annotated genotype database in OASIS is populated with 27 million exonic and noncoding variants from genotyping and whole exome sequencing. OASIS currently contains genomic, metabolomic, transcriptomic and methylomic association results. In the 12-month period ending June 2019, 30 thousand OASIS queries were performed by 35 University of Maryland users.
A version of OASIS for UK Biobank (UKB) data was developed during 2020. This system contains full annotation on the 92 million imputed variants from the UKB and allows LD to be computed directly from the individual-level data on 502,520 subjects. The “UKB OASIS” system contains association results on over 3300 phenotypes from our own analysis and from summary statistics made available on public websites. Thus, when an OASIS search identifies one or more variants of interest, extensive PheWAS information is also available.
I am a member of 10 Working Groups in NHLBI’s TOPMed Program (Trans-Omics for Precision Medicine) and developed a separate “TOPMed OASIS” website in 2018 as a contribution to that program. The original OASIS for the Amish design scaled up nicely to handle TOPMed’s one billion variants for 140,000 subjects in TOPMed Freeze 8. As of September 2020, TOPMed OASIS contains 384 datasets contributed by 80 users from 12 TOPMed Working Groups (Diabetes, Kidney Function, Hematology & Hemostasis, Lipids, Anthropometry & Adiposity, Bone Mineralization, Population Genetics and Coronary Artery Calcification, Blood Pressure, Platelet Aggregation, Telomere Length, Structural Variation). OASIS users include MD’s, PhDs, Post Docs, Graduate Students and Medical Students.
I am also a member of the CHARGE Consortium (Cohorts for Heart and Aging Research in Genomic Epidemiology) and participate in the Analysis and Diabetes Working Groups. Plans are being developed to add OASIS genotypes platforms for HRC and 1000Genomes so that OASIS can be used to examine the results of meta-analysis performed by CHARGE Working Groups using imputed genotypes.
Automated Spectrometric Analysis My early research involved development and construction of computerized analytical instrumentation for spectrometric analysis. State-of-the-art microprocessor technology and newly-discovered laser systems were integrated to provide a flexible analysis system.

Genetic Association Studies I have worked extensively with genomic data from the Old Order Amish, performing association analysis to link genotypes to a broad range of phenotype data collected over multiple decades. The work has involved working with public databases as well as the development of unique analysis tools for searching, filtering, annotating and visualizing both genetic variants and association results. I have also worked extensively with statistical genetics tools, including SAS, Plink and MMAP, to identify statistically significant genetic associations in the Amish, a founder population with a unique structure.
