My lab uses pollen tube growth and guidance as a model system to understand the mechanisms of invasive cell growth, guidance of cellular migration, and determination of cellular polarity. We study the fertilization process in flowering plants because the success of this fundamental component of the life cycle depends on a lengthy and precisely guided cellular journey.
Mark received his B.S. in Biology from Wake Forest University in 1993 and completed his graduate work in Microbiology/Cell and Molecular Biology at the MSU-DOE Plant Research Laboratory at Michigan State University (Ph.D. 2000) where he studied mRNA degradation with Dr. Pamela J. Green. Mark began working on plant reproductive development while he was an NIH Ruth L. Kirchstein National Research Service Award postdoctoral fellow at The University of Chicago with Dr. Daphne Preuss (2000-2004). Mark joined the faculty of Brown University in September of 2004.
