Postdoctoral work with Dr. Howard Goodman
The Arabidopsis zinc finger project began in the Goodman lab at Massachusetts General Hospital
Graduate work with Dr. Maarten Chrispeels
My work as a graduate student in the laboratory of Dr. M. Chrispeels used yeast and tobacco as model systems for determining organellar targeting signals on plant proteins. Collaborative work showed that the C-terminal signal -KDEL* in conjunction with a signal peptide allowed ER targeting of a normally vacuolar protein. My thesis work examined the vacuolar targeting domain of the plant protein phytohemagglutinin, (PHA). Fusion proteins were generated between portions of PHA and the yeast secreted protein invertase. A small domain near the N-terminus of PHA was sufficient for targeting of this yeast protein to yeast vacuoles and to tobacco vacuoles. Vacuolar targeting has become an important means of increasing the percent of total protein produced by a transgene in transgenic plants.

Undergraduate work with Dr. Susan Gerbi
My work in Dr. S. Gerbi’s lab involved the determination of the primary structure of the Xenopus laevis rDNA and, by inference, the rRNA. This was a collaborative effort that represents approximately 10 people-years of work, an undertaking difficult to imagine in this day of sequencing genomes. The sequencing work led to testable models for the secondary structure of Xenopus 28S rRNA and for rRNA processing.
