Gao, Rachel Rachel Gao graduated in 2014 from the University of Maryland, College Park, with a B.S. in Biological Sciences. She previously gained toxicology research experience working under Dr. Pal Pacher at the National Institute of Alcohol Abuse and Alcoholism (NIAAA) from 2008 to 2010. She demonstrated that co-incubation with Resveratrol was able to ameliorate azidothymidine (AZT)-induced cardiotoxicity by reducing mitochondrial oxidative stress generation, caspase activation and cell death. From 2010 to 2012, she continued to do research in a developmental genetics lab under the supervision of Dr. Yingzi Yang, at the National Human Genome Research Institute (NHGRI). She contributed to the discovery that molecular signal, Wnt, may help signal progenitor cells into osteoblasts or chondrocytes. Rachel joined the Toxicology PhD program in August 2016 under the guidance of Dr. Cynthia Ju. Her current research focuses on macrophage derived Hypoxia Inducible Factor (HIF) and its role in acetaminophen induced acute liver injury.
Hari, Ashwini Ashwini Sri Hari, a native of Tamil Nadu, India, completed her B.S. in Biotechnology from Anna University in 2012. For her undergrad dissertation, she worked on designing DNA barcodes for the rapid identification of leather products. She then earned her Master’s degree in Biotechnology from BITS, Pilani in 2014 where she worked on assessing the toxicity of titanium dioxide nanoparticles in earthworms. Driven by her interest to understand how oxidative stress can influence a spectrum of disease states, she applied to the Dept. of Pharmaceutical Sciences at the Anschutz Medical campus to pursue her PhD in Toxicology in 2015. Ashwini joined Dr. Manisha Patel’s lab in 2016. Currently, she is investigating the correlation between neuroinflammation and oxidative stress and how they contribute to the generation of recurrent, spontaneous seizures in the epileptic population.

Following his time at Iowa State, Brian accepted an offer to work at National Jewish Health in the laboratory of Dr. Lee Newman. Brian left National Jewish along with Dr. Newman shortly thereafter and accepted the position of Sr. Professional Researcher / Laboratory Manager for Dr. Newman at the University of Colorado Denver back when it was still called the Health Sciences Center. After researching the T cell mediated occupational disease, Chronic Beryllium Disease, for nearly 10 years, Brian joined the Molecular Biology Program at CU Denver in the fall of 2015. Following the successful completion of his first year, Brain joined the laboratory of Dr. Nichole Reisdorph and transferred into the Toxicology Program at the beginning of fall semester 2016. Brian is currently interested in learning how polycyclic aromatic hydrocarbons differentially drive metabolome alterations in different immunologically relevant cell types such as professional antigen presenting cells and T cells.
