Research Interests

Our lab is interested in the regulation of normal and abnormal nervous system development, and in determining how understanding these mechanisms may be exploited to stimulate repair when cells of the nervous system become injured or succumb to disease. Many different types of neurons and glia co-exist throughout the brain, however, and their genesis, at different times in different brain regions, creates a confusing milieu in which to study events that occur early in embryogenesis. To overcome this, most of our early discovery research has historically utilized a simple, fascinating and uniquely talented part of the nervous system - the olfactory system.


The olfactory neuroepithelium (OE) is a primitive parts of the nervous system, that the only recognized projection neurons capable of successfully replacing themselves and re-targeting their axons from the peripheral to central nervous system in a mature animal. In the last 10 years, our research in the olfactory system has revealed novel subtypes of stem cells and progenitors, novel mechanisms used by transplanted olfactory glia to mediate spinal cord repair, and different ways we may be able to use epigenetic regulation mechanisms to prevent neuronal death in the developing and injured nervous system. All the research we currently perform looks beyond the olfactory system into the brain and is aimed at understanding (1) Neural stem cell regulation; (2) Glia-based mechanisms of stimulating regeneration and brain repair and (3) How the DNA of cells within our brain becomes epigenetically altered as cells become specialized when we stimulate our brain (epigenetic regulation of brain development and function).

The Roskams Lab is essentially split into research groups ( the "neural stem cell bay" the "glia and regeneration bay" and the "epigenetics bay") focussed on each of the following areas, whose interests become more intertwined the deeper we probe into some of the intrinsic mechanisms common to each. Although we no longer have an active research program in neuronal death mechanisms, neuronal protection is a key aim in many aspects of research in the three current lab groups.
