Research interests: My research interests center around visual receptor function. My specialties are visual sensitivity to ultraviolet light, rhodopsin, and vitamin A's diverse effects in visual receptors. In addition to being the chromophore that absorbs light in the rhodopsin molecule, my research demonstrates that vitamin A controls transcription of genes relevant to vision. Zeaxanthin and lutein are interesting carotenoids since they provide 3-hydroxy retinal, the chromophore of Drosophila's rhodopsin. Zeaxanthin and lutein also protect the human macula from blue light. My research is detailed on the web: http://starklab.slu.edu/
Research opportunities: Students have always been the sine qua non of my college-oriented research program. In my 35 year publication career, 100 students share authorship or are acknowledged in my research publications.
