Julie A. Reisz Haines, PhD

Research Assistant Professor

Julie is originally from Pittsburgh, PA and received her PhD in Chemistry from Wake Forest University where she used NMR and MS to investigate the reactivity of nitrogen oxides with organophosphines and thiol- and heme-containing enzymes. Her postdoctoral work at Wake Forest School of Medicine (Section on Molecular Medicine) focused on redox modifications of protein cysteines, particularly in the peroxiredoxin family, using MS-based proteomics approaches. She next taught undergraduate level chemistry and managed the MS facility at Wake Forest, then joined the University of Colorado in 2015 where she utilizes high throughput metabolomics to profile metabolic responses occurring in numerous diseases and physiological perturbations. Her specific research interests include metabolic responses along the spectrum from hypoxia to oxidative stress and investigating RBC protein oxidation during storage. Outside of science, Julie enjoys hiking with her family and running half marathons.

Travis Nemkov, PhD


After completing his BA at the University of Colorado, Travis helped to jump start operations as the first employee at a new start-up company, AmideBio, where he developed methods to produce notoriously difficult peptides with high purity and efficiency. Four years later, he left to pursue a PhD in Dr. Kirk Hansen’s lab at the University of Colorado Denver where he developed high-throughput methods for metabolomics to study RBC responses to hypoxia and storage and published more than 40 papers in the process. Having already worked closely with Angelo on these projects, Travis decided to stick around as his first post-doctoral fellow where he has been focused now on high-throughput proteomics. In addition, he is interested in understanding the role of metabolism in blood cell development throughout the arc of life, from primitive embryonic erythropoiesis to chronic anemia of inflammation seen later in life. Born and raised in Colorado, Travis refuses to leave if he doesn’t have to, and just prefers to travel the world instead.

Prior to his doctoral studies, he earned an MS in Biological Sciences and a BS in Biochemistry, both from Southeastern Louisiana University.

Sarah Gehrke, B.Sc.

Senior Professional Research Assistant

Sarah is a native of Colorado where she received her B.Sc. in Chemistry from the University of Colorado in Colorado Springs.  There, she used CE to investigate novel methods for measuring neurotransmitters in human urine for application to disease monitoring.  After receiving her degree, she worked as a research scientist in a team researching fly ash remediation and CO2 capture. There, she honed her bench technique and analytical skills, including utilizing various instrumentation, particularly ICP-MS and IC, among others.  She next worked with a highly skilled team as an analytical chemist, researching biomass conversion to industry-important chemicals.  During her time there, she continued to polish her analytical skills in a high-throughput research laboratory setting, chiefly utilizing TOC, LC and IC.   Her current research focuses on the development of new metabolomics approaches for high-throughput and metabolic tracing applications, especially in the fields of cancer metabolism and mammalian hibernation.

Evan J Morrison, M.Sc.

Graduate Student

Evan J. Morrison is a Ph.D. student in the Molecular Biology Program (T32 fellowship recipient), where he studies the metabolome of red blood cells in the context of aging and disease. Evan earned his B.S. in Chemistry and B.A in Philosophy at the Metropolitan State University of Denver, where he used chemical probing to determine higher order lncRNA structures in 3’ untranslated regions in a family of nepoviruses, and how higher order folding directed non-canonical translation initiation.  Additionally, Evan trained in analytic philosophy and studied Wittgenstein’s Tractatus Logico-Philosophicus, as well as the role of metaphors in cognitive linguistics. After completing his degrees,  Evan became a laboratory researcher at National Jewish Health, where he researched the epigenetics of metabolic disorders and explored the role of exosomes in the pathogenesis of Diabetic Nephropathy, Non-alcoholic Fatty Liver Disease, Sarcoidosis, and Idiopathic Pulmonary Fibrosis. Outside of the lab, Evan still can be found brooding about philosophy.
