Lloyd-McCullough Group Members
Dr. Irina Minko, Staff Scientist
Irina attended the Moscow State University and the Institute of Biochemistry of Russian Academy of Sciences. In 1999, she joined the Lloyd lab at the University of Texas Medical Branch in Galveston, Texas and continued her research when the lab transitioned to OHSU, Portland. Irina's work has been developed in the following directions: (i) The biochemical and cellular processing of DNA-protein cross-links; (ii) The role of specialized DNA polymerases in the bypass of DNA lesions; and (iii) The mutagenic consequences of cellular processing of damaged DNA. Currently, the main focus of Irina's research is on repair of DNA-DNA cross-links.
Dr. Harini Sampath, Staff Scientist
Harini Sampath completed her doctoral training in Biochemical and Molecular Nutrition at the University of Wisconsin-Madison in 2008. Having obtained extensive training in lipid and carbohydrate metabolism and ER stress pathways in the development of obesity, Dr. Sampath joined the Lloyd lab in 2009. She is currently interested in delineating the molecular pathways leading to metabolic dysfunction in mice deficient in the DNA glycosylase, NEIL1. Her studies are particularly focused on understanding the relationships between oxidative stress, mitochondrial dysfunction, and metabolic syndrome. In her free time, Harini enjoys traveling and developing recipes for her vegetarian food blog.
Eleonora Juarez, Graduate Student
Ellie is from Monterrey, Mexico and grew up in Brownsville Texas. She received her Bachelors of Science in Biology from The University of Texas at Brownsville. She came to Portland in the fall of 2011 and joined the PMCB program at OHSU. She is currently a graduate student in the Molecular and Medical Genetics Department and a member of the McCullough-Lloyd lab. Her current work focuses on the importance of chromatin remodeling for the processing of DNA-protein crosslinks induced by formaldehyde exposure. When not in lab she loves exploring new cuisines and restaurants in around the Pacific Northwest, and attending all sorts of sports events. GO SPURS GO!
Dr. Vladimir Vartanian, Research Technician
Vladimir received a PhD degree in Linguistics from the Institute of Linguistics at the Russian Academy of Sciences in Moscow. His interests focused on the psychological and social aspects of language. He became interested in biological research and joined the lab in 2003. He currently studies the role of oxidative stress and was first to observe the metabolic syndrome in NEIL1 deficient mice. In his free time, Vladimir enjoys creating art with an emphasis on drawing and painting. Selections of his work are available for purchase through Forever Art.
