Research Focus

The focus of Dr. Rougier’s research is the early evolution of mammals. Phylogeny, biogeography, and morphological transformations are the major topics being developed. Several sources of data are employed to gather information on past evolutionary history—prominent among them are fossils and embryos. A dynamic field program includes/included fossil collecting in USA, Argentina, Bolivia, Japan and Mongolia.

My research has focused on anatomy/evolution falling broadly within Anatomical Sciences disciplines. Highlights of my research to date are 11 publications in Science or Nature, including 1 cover as lead author in each one of those journals, and a paper as a lead in PNAS. As I have become more senior and responding to changing demands in ASNB, I have progressively become more involved in the teaching mission of the department. I assumed leadership roles (Course director, co-course director, block director, thread director) in several of the courses for which ANSB is responsible and  in conjunction with Dr. Brian Davis I developed a 500/600 level course from scratch (Origin of the Mammalian Sensory Systems and Comparative Neurobiology). During this time I transitioned from Gross Anatomy to Dental Histology, helped solve a leadership crisis, modernized the course, prepared it to transition to an integrated curriculum, and dramatically improved student/administration ratings and student satisfaction. I see myself serving a similar/greater role in teaching and leadership in the near future. I welcome students interested in any aspect of morphological, evolutionary research. I have mentored students pursuing a career in Research, Professional Careers in medicine and dentistry, as well as Graduate education and teaching. I have just published a book with two former students of mine..see below!


Current Projects

During the past four years, most of the research projects were directed toward solving the interrelationships of very primitive groups of mammals, only distantly related to living forms, particularly from South America. However, recent discoveries have permitted important advances with regard to the origin of marsupials and placentals,and the establishment of the modern fauna.

I have been deeply involved in fieldwork in several parts of the globe, including South America and three different locations in Asia. Masters students and Ph.D. Students have occasionally participated in these trips. These projects have served to expand the department’s student base through the recruitment of  minority Ms. and Ph.D. student.
