Post docs and Staff

Kazuhiko Kawasaki, Ph.D.

Dr. Kawasaki is a Research Associate with a background in molecular biology and genomics. His research interests include: Developmental genetics, Dento-craniofacial patterning and development, interactions between the chondrocranium and the dermatocranium. Evolution of the SCPP gene family—biomineralization and lactation—duckbilled platypus, coelacanth, gar, pufferfish, zebrafish, nurse shark, and lamprey. Special skill: Finding exons by reading genomic sequences

Mizuho Kawasaki, B.S.

Mizuho Kawasaki is a Research Technician in the Richtsmeier Lab. She obtained her BS in Pharmaceutical Science at the Kyoritsu University (merged with Keio University) of Pharmacy in Japan. She is primarily involved in the maintenance of our mouse colony, genotyping by PCR, performing immunohistochemical and histochemical staining, whole embryonic staining and other general lab duties.

Susan Motch Perrine, Ph.D.

Dr. Perrine is a postdoctoral research assistant in the Richtsmeier lab, where she focuses on the physiology and genetics of craniofacial development and dysmorphology. She obtained her BS and MS in Animal Sciences from the Pennsylvania State University. She obtained her PhD in Physiology from Penn State in 2010, studying aging and the physiology of stress. Some of her work involved magnetic resonance imaging (MRI) and dual energy x-ray absorptiometry (DEXA), methods of interest in the Richtsmeier laboratory. She is currently working with mouse models of craniosynostosis to understand genotype-phenotype correspondence and craniofacial variation using an interdisciplinary approach which combines high resolution imaging, geometric morphometrics and wet lab techniques.

Nandini Singh, Ph.D.

Dr. Singh is a physical anthropologist, with a speciality in human and non-human ape skull development and evolution. In my research I use an interdisciplinary approach to explore the evolutionary and developmental basis of morphological variation in the primate skull form as well as in craniofacial disorders. My background in human evolution and postdoctoral experience in evolutionary developmental biology enable me to employ an interdisciplinary approach to address questions that can further our understanding of developmental mechanisms that drive morphological evolution in hominoids, and mammals in general. I combine evolutionary concepts such as morphological integration and heterochrony with clinical research to investigate key developmental pathways (for example Sonic Hedgehog signaling) that are implicated in the formation and patterning of the mammalian skull, and which when disrupted, cause severe midfacial and forebrain anomalies. I use advanced imaging, 3D geometric morphometrics and multivariate statistical techniques to quantify and analyze morphological data generated through experimental manipulation of embryonic skull growth in mice, mapping the genetic to phenotypic change.
