Biography

I received my B.A. in Biology from Reed College in 1977, with an undergraduate thesis on the biological effect of ionizing radiation from nuclear power plants. I received a Masters Degree in Genetic Counseling from the University of California Irvine in 1980 where my thesis research involved Pompe disease. I received my Ph.D. in Molecular Genetics from the University of Wisconsin Madison in 1989, where my thesis research involved homologous unequal crossing-over in the beta type globin genes. I conducted post doctoral research at the University of California San Francisco working in the Prenatal Genetics Clinic, and teaching medical genetics to the medical students. I came to California State University Northridge in 1995 to join the Biology Faculty, where I currently conduct research in my laboratory with undergraduate and graduate students.

Research Specialties

I remain interested in the molecular basis of rare, heritable disorders. Our work has recently focused on Chondrodysplasia Punctata (CDPX2), which is due to a defect in cholesterol biosynthesis. Another disorder that we are studying is Dyskeratosis Congenita (DKC), a lethal telomerase defect. We have expanded our horizons towards treatment of heritable disorders, including Mucopolysaccharidosis II (MPS2), Neurofibromatosis 1 (NF1), Hereditary Inclusion Body Myopathy (HIBM) and sickle cell anemia.

The techniques used in this work include isolation of DNA and RNA, restriction enzyme digestion and separation of fragments by gel electrophoresis, Southern analysis, Northern analysis, Real-Time PCR analysis, screening of cDNA and genomic libraries to isolate genes, PCR (polymerase chain reaction) amplification of genes or their exons for further study, nucleotide sequence analysis, computer manipulation of sequences, database searching, tissue culture, transient transfection, enzyme assay, immunologic assay, and confocal microscopy
