Directed research


A diploid zygote of the yeast Saccharomyces cerevisiae (propeller-shaped cell in the center of the micrograph) produces it's first bud.  Zygotes form from fusion of two haploid cells of opposite mating type.



My research currently focuses on understanding the cell biology of two genes COD1/SPF1 and yor291w in yeast Saccharomyces cerevisiaeCOD1/SPF1 and yor291w encode proteins belonging to a family of ion pumps known as P-type ATPases.   My past work focused on role of Cod1p in maintaining cellular ion homeostasis and in maintaining the function of the endoplasmic reticulum. Currently I am interested in identifying the molecular substrates of Cod1p and yor291p.
