I am an ophthalmologist working at the Research Institute of the Veterans Health Service Medical Center. I spend most of my time researching. On the research front, I concentrate on genetic analysis for public health as well as clinical and translational research. My most recent papers are shown below. Risk Allele Frequency Analysis and Risk Prediction of Single-Nucleotide Polymorphisms for Prostate Cancer. Genes (Basel). 2022 Nov 5;13(11):2039. doi: 10.3390/genes13112039.
