- Neural-vascular development, epigenetic regulation of vascular-microenvironmental interactions in development and disease
My current teaching includes a combination of upper and lower division courses that are designed to encourage interactive learning paradigms. In the Fall, I teach Developmental Biology (BIO378) that provides an overview of general developmental biology principles, including the general stages of development associated with a variety of species, experimental approaches used to study developmental processes, and the genetic and environmental influences that govern development. Over the years, I have taught a variety of courses, including General Biology I (BIOL150), General Biology II (BIOL151), Special Topics Seminars (BIOL491/503) on the Brain, Cell and Molecular Biology, and Integrative Biology, the Biology Senior Capstone (BIOL480), Orientation to the Major (BIOL120), and Scientific Writing (BIOL509). In all my teaching, I incorporate team-based learning approaches and discussion as part of student-centered learning.
The overarching theme of my research addresses how changes in gene expression patterns regulate cell fate choices during central nervous system (CNS) development. In addition to the regulatory processes that occur during normal development, I am interested in the cell, molecular, and epigenetic changes that occur in response to environmental toxins. I am a member of the Society for Neuroscience, the North American Vascular Biology Organization (UND Campus Representative), and the Society for Developmental Biology.
My current research addresses the influence of heterotypic cell-cell interactions during central nervous system development. My work is designed to test the hypothesis that neurovascular interactions stabilize the vasculature during development and under pathologic conditions. I am also investigating the role of a traditionally vascular factor, vascular endothelial growth factor (VEGF) on the regulation of neurogenesis. I am currently conducting these studies using in vitro cell culture approaches and an in vivo system using transgenic mice. I also collaborate with Dr. Tristan Darland to investigate the impact of environmental toxins (i.e. cadmium) on the development of the nervous system using the zebrafish as a model organism. The rationale behind these latter investigations is to determine the impact that early, low levels of toxin exposure can have on not only the neural stem cells of the developing system, but also on the ability of the adult system to respond to stress.
In addition, I am a member of the UND Epigenetics and Epigenomics group and am investigating the epigenetic mechanisms that control neural stem cell fate choice and neural-vascular interactions in early mouse cortical development. This work is funded by the COBRE grant on "Epigenetics and Epigenomics of Development and Disease".

Role: Project Director 07/11/19-07/10/22
Project: The role of class IIa Hdac in regulating cell fate choice in early development. The goal of the proposed studies is to understand how microenvironment-induced, acetylation-based modifications to chromatin influence cortical gliogenesis during development and in glioma tumor progression. The proposed work targets the intersection of development and disease at two levels: neural stem cells as they alter cell fate in response to vascular cell cues and glioma cells as they progress in tumor stages in response to vascular cell cues.
