Research Interests

Human Genomics

The Geisinger MyCode Project is a system-wide biorepository for broad research use that is linkable to Geisinger’s electronic medical record database. By early 2013 >40,000 Geisinger patients had consented to participate; enrollment is ongoing. More than 10,000 DNA samples have undergone genome wide genotyping; additional analysis is underway. Genomic data is combined with data in Geisinger’s clinical database for genetic association or phenome wide association studies. Algorithms for phenotyping using health record data are developed and validated, creating a versatile pipeline for genomic discovery. We are also developing methods for incorporating genomic information into clinical practice. One example involves preemptive sequencing of a pharmacogenomic gene panel for drug prescribing. 

Abdominal Aortic Aneurysm

AAAs are the 13th leading cause of death in the US. Most AAA-related deaths result from rupture of undiagnosed aneurysms. Research is underway to identify genetic and non-genetic risk factors for AAA and AAA-related complications, with the goal of developing novel therapies and better risk assessment. A research cohort of 1,000 Geisinger AAA cases and several thousand controls has been created. Whole genome and exome genotyping and next-gen sequencing of a subset of cases has been completed. Clinical and demographic data from Geisinger’s electronic health record database were also analyzed. These data are being used to create a AAA risk algorithm that will be evaluated for its utility to guide outpatient screening. 

Extracellular Matrix Biology

A long-term research interest is the role of ECM in modulating cellular function. We are currently investigating the role of ECM collagens in adipocyte differentiation and function. Expression of collagens and collagen receptors is regulated during adipocyte differentiation. Inhibitor studies showed that these gene products are critical for adipocyte differentiation and function. Current efforts are focused on elucidating the underlying molecular pathways in adipocyte cells lines and mouse models.
