Xia Yang, Ph.D.

Biography

Dr. Xia Yang received her Ph.D. in Molecular Genetics and Bioinformatics from Georgia State University and had postdoctoral training in Systems Genetics at UCLA. She was Senior Research Scientist at Rosetta Inpharmatics/Merck & Co. and Director of Systems Biology at Sage Bionetworks prior to returning to UCLA as a faculty member.

Research Interests

Our research focuses on developing and applying multitissue multiomics systems biology approaches to dissect the molecular networks underlying diverse complex diseases, ranging from cardiometabolic diseases to neurodegenerative and neurological disorders, and utilize the systems level networks to guide precision medicine. Through integration of genetic, transcriptional, epigenomic, proteomic, gut microbiota, and phenotypic data from human and rodent populations, we investigate how complex interactions between genetic and environmental risk factors perturb tissue- and cell-specific gene networks which in turn induce variations in disease susceptibility. Subsequently, we use the causal molecular networks of diseases as the basis for therapeutic target identification and biomarker discovery.

Aaron Blaisdell, Ph.D.

Biography

After receiving his BA and MA in Biological Anthropology (at SUNY Stony Brook and Kent State University, respectively), Dr. Blaisdell realized that animal cognition was even more interesting than dead humans. So he trekked on over to SUNY Binghamton for his Ph.D. in Experimental Psychology with Dr. Ralph Miller, where he studied learning, memory, and temporal cognition in the rat. This was followed by a brief stint as an NRSA Postdoctoral Fellow with Dr. Robert Cook, an expert on Avian Visual Cognition at Tufts University, where he learned how pigeons perceive and think about the world. Since 2001, Dr. Blaisdell has emigrated to the climatological and cultural paradise of sunny LA as Professor in Learning & Behavior and Behavioral Neuroscience in the UCLA Psychology Department. He presides over a comparative cognition lab, studying cognitive processes in rats, pigeons, hermit crabs, and humans. His lab website is http://pigeonrat.psych.ucla.edu.
