Néva earned a Ph.D. from the University of Washington by examining how different types of neurons develop in the chick spinal cord, which was funded by an HHMI predoctoral fellowship. She also was involved in the Science Education Partnership, which integrates science into the community through outreach activities. As a result of her graduate studies, Néva became interested in the broader question of how nervous systems evolved. She began to address this question as a postdoctoral researcher in Dr. Elaine Seaver’s lab at Kewalo Marine Lab, University of Hawaii and is continuing this research at Clark University.
Dr. Meyer received a B.S. in Molecular Biology from Purdue University in 1998 and a Ph.D. in Molecular and Cellular Biology from the University of Washington in 2005.

Not too long ago, I sorted my first bowl of marine zooplankton. So many forms, sizes, colors and yeah, so many animal phyla all clumped together there in that small space. Definitely what got my attention from the beginning were the different kinds of marine invertebrate larvae drifting around the water column. Since then, I devoted myself to understanding marine invertebrates in a particular way, through studying their larvae. Years, and a lot of tows, later brought me to Néva’s lab where I will study one of my favorite groups: annelids. Here I will use modern molecular techniques to understand how different traits evolved, such as segmentation of the nervous system or the innervation and control of ciliary bands.

Broadly speaking, I am interested in understanding the evolution of nervous systems across different species and the molecular mechanisms underlying nervous system development. As I came from a systems biology lab, I wish to use a similar approach to identify and characterize novel factors in annelid neurogenesis. Through different approaches, like high throughput RNA-Seq and qPCRs, I am trying to understand the different mechanisms underlying neural stem cell maintenance and their differentiation into various neural subtypes in Capitella teleta.

I am very interested in understanding how stem cells make the transition from being undifferentiated precursor cells to differentiated neural cells. I am studying the role of Notch/Delta lateral inhibition and a soxB1 homolog (Ct-soxB1) during this process in Capitella teleta. I am using the gamma-secretase inhibitor DAPT to block Notch signaling and examine the effect on neural development. I am ultimately interested in studying central nervous system regeneration in humans and the effects of this on mental illness. My current work has the potential to strongly connect to human health and development, especially in the realm of mental illness, because C. teleta has the ability to regenerate the majority of its central nervous system.

Recent research has shown that BMP signaling may act as a short range signal during dorsal-ventral patterning in annelids (Kuo and Weisblat, Curr Biol. 2011). Interestingly, this study demonstrated that Gremlin is the likely BMP antagonist during this process (no chordin homologs have been found in annelids). However, evidence from annelids and enteropneusts also suggests that, BMP signaling does not determine the dorsal-ventral boundary of neural ectoderm. I am currently using exogenous recombinant BMP4 protein to study the effect of BMP signaling on neural fate specification in Capitella teleta.
