Lee Niswander, PhD

Principal Investigator

Chair, MCDB

Jing Zhang, PhD

Research Associate

Jing’s study is particularly focused on exploring mechanisms of long noncoding RNA dynamically interplaying with protein  and other kind of noncoding RNAs (microRNAs) through specific RNA modifications and their possible functional contribution to human congenital disease.

Heather Brown

Doctoral Candidate

Heather's research focuses on Snx3, a sorting nexin gene involved in intracellular retrograde transport of the WNT ligand, WLS. She is investigating a mechanism by which the absence of Snx3 could result in neural tube defects by investigating it's involvement in Wnt signaling and neuronal patterning in the developing mouse embryo. 

Binbin Li 
Postdoctoral Fellow 

Binbin's current interest is focused on a rarely studied gene-Tmem132a, knock out of which in mice leads to severe developmental malformations including spinal bifida. He is also interested in discovering mutations in the human population compared to mutations in mice to give a better understanding of how specific gene`s deficiency contributes to NTD occurrence. 

Huili Li, MS

Research Associate

Huili's study is particularly focused on uncovering whether and how nutritional environmental factors affect neural tube closure. She studies morphological, molecular and functional interactions to understand the impacts of abnormal concentration of nutritional factors on neural tube closure. 

Eric Jaffe
Doctoral Candidate 

Eric’s research focuses on the non-neural ectoderm, and the role of the protein GRHL3, a transcription factor necessary for spinal neural tube closure. In particular he is interested in how Grhl3 may control epithelial state and the actin cytoskeleton during neural tube closure. He is also interested in understanding axial biases shown by Grhl3 mutants when compared to its family member Grhl2.
 

Lori Bulwith 
Professional Research Assistant

Lori executes various managerial and laboratory tasks in the Niswander lab. She specializes in murine reproduction and colony maintenance.

Sofia Pezoa
Doctoral Candidate

Sofia is interested the development of neural crest cells, a unique population of cells that is specified during neural tube closure in mouse. Recently, she helped identify an epigenetic modifier that has a craniofacial defect, suggesting a role for epigenetic regulation during neural crest cell development. To investigate her hypotheses she uses a combination of in vivo and in vitro techniques, looking at the development of cranial neural crest cells.
 

David Engelhardt

Doctoral Candidate

David studies gene-environment interactions which affect the penetrance and expressivity of gene-mutations. His current research focuses on a suite of cilia gene-mutations that produce neural tube defects at rates uniquely dependent on folic acid level. David pairs in vitro and in vivo models with bioinformatic tools to investigate this relationship.

Mayela Gayosso

Postdoctoral Fellow

Mayela’sresearch focuses onACTR5, an Actin Related Protein. She is investigating a mechanism by which the absence of ACTR5 could result in a severe microcephaly in the developing mouse embryo. To dissect the ACTR5 functions during the brain development in early embryogenesis she uses a combination of in vivo and in vitro techniques, looking for morphological, molecular and functional interactions.

Marisela Gonzalez-Cruz

Predoctoral Candidate

Marisela's current research focuses on a long non-coding RNA called lncRncr3 for its potential role in causing the birth defect microcephaly. lncRncr3 is currently known as the host primary transcript of one of the most studied microRNAs in the brain called miR124a. The expression of miR124a can be regulated by a process called alternative polyadenylation (APA) of the long non-coding RNA. Her goal is to determine the importance of this APA phenomenon in embryonic neural development as well as the role of lncRncr3 in preventing microcephaly.
