1) Virology (BIOM 435) 3 CR Spring semesters.
2) Advanced Virology (BIOM 509) 3CR Fall semester, even-numbered years.

Molecular biology of human cytomegalovirus (HCMV) replication.
Current research goals:
1) To characterize the glycoprotein complexes present in the HCMV envelope that mediate attachment and entry.
2) To define the mechanisms by which HCMV enters different types of cells.
3) To better understand the specific roles of epithelial and endothelial cells in the pathogenesis of HCMV disease.
