Nickolas SteinauerNickolas Steinauer, an MD/PHD student in Dr. Jinsong Zhang's lab, won a Travel Award to attend the 2016 ASH Meeting on Hematologic Malignancies held in Chicago this September.

Nick's abstract was chosen as one of the top 6 abstracts for oral presentation at the meeting. He is currently supported by the T32 training grant in the Department. Congratulations, Nick!
ASH Meeting September 2016
Lauren Stein, a graduate student in the Yosten/Samson lab, received her doctorate at the SLU 2016 Graduate Programs commencement exercises May 12th. In April Dr. Stein received the Research Recognition Award from the Endocrinology and Metabolism Section of the American Physiological Society for her work identifying the receptor of the novel peptide hormone, Phoenixin, which was discovered by Drs. Yosten and Samson in 2013.

Dr. Stein has accepted an NIH funded postdoctoral fellowship in the Department of Psychiatry and the Translational Neurosciences Program at the Perlman School of Medicine, University of Pennsylvania. Dr. Stein will be continuing her studies on  the neuroendocrinology of energy balance in the laboratory of Dr. Matthew Hayes.

Research Summary

The laboratory seeks to understand fundamental patterns of organization in the basal forebrain, how forebrain systems contribute to behavioral synthesis and brain development and what the vulnerabilities of different forebrain systems are in circumstances leading to neurodegeneration.
