Teaching Cell and Molecular Processes Core: I provide yearly lectures to first year medical students involving several areas of human genetics and molecular biology including gene mapping, gene therapy, DNA Microarrays, Next Generation DNA Sequencing and functional genomics. Pharmacology 820: I present a lecture in this course offered by the Department of Pharmacology at UNMC. This lecture covers the history, laboratory techniques, and fundamental research applications of DNA Microarray Technology.

Research Interests: Next Generation DNA Sequencing strategies for rare Mendelian disease gene identification and functional genomic technologies in general. I also collaborate on a number of research projects at UNMC involving many different areas of biomedical interest including cancer, cardiovascular disease, and virology.

Microarray Core Facility: This facility is comprehensive in scope and provides microarray service and support for both the Affymetrix GeneChip System and spotted DNA array platforms. The laboratory routinely processes many of the gene expression and genotyping arrays offered by Affymetrix. The facility is also fully equipped with all the necessary instrumentation for hybridizing, scanning and analyzing spotted arrays. Collectively, the Affymetrix and spotted array platforms allow researchers to measure the genome-wide activity of tens of thousands of genes in parallel in a variety of model organisms.

DNA Sequencing Core Facility: Our DNA Sequencing Core Facility serves the role of the UNMC research DNA sequencing facility. In addition to traditional sequencing of PCR fragments and plasmid inserts, we have also employed Next Generation Sequencing technology. In 2010 I was awarded a Shared Instrumentation Grant from the NIH General Medical Sciences (formally National Center for Research Resources or NCRR). This Illumina Genome Analyzer IIx instrument will be operated in the context of a Next Generation Sequencing Core facility and service a variety of projects related to biomedical research; including cancer, diseases of the retina, HIV, inherited neurological disorders and others. In 2011, the GAIIx instrument was upgraded to an Illumina HiSeq2000 with funds obtained from a Nebraska Research Initiative grant. In addition, we are looking forward to upgrading the HiSeq2000 to a HiSeq2500 instrument in November of 2012 utilizing funds obtained from a Nebraska Research Foundation grant.

Through a collaborative and interactive relationship with the newly established Center for Bioinformatics and Systems Biology, we aim to provide functional genomics technological support for the UNMC campus.
