Esteban Moya, PhD
Project Scientist
Esteban is a Project Scientist interested in physiological responses to hypoxia in animal models and human populations living at high altitudes. He obtained his Ph.D. in Physiological Sciences at the P. Universidad Católica de Chile studying the carotid body, cardiorespiratory, and oxidative responses in an animal model of obstructive sleep apnea. Currently, his interests include understanding the consequences of sustained hypoxia on the neuroplasticity occurring in the neurons and glial cells of the brainstem areas that control the ventilation in rodents. As well as the genetic and physiological basis for the control of breathing in human populations living at high altitudes.
Katie A. O’Brien, PhD.
Marie Sklodowska -Curie Global Research Fellow
Katie is a Marie Sklodowska-Curie Global Research Fellow based between the University of Cambridge and UCSD. The aim of her current Fellowship is to characterise the high-altitude metabolic phenotype driven by unique Andean genetics. She completed her doctorate in 2017 on metabolic profile changes and effects of dietary nitrate supplementation in hypoxia at King’s College London under the supervision of Prof. Stephen Harridge. During this time, she was a scientific investigator on the Xtreme Everest 2 research expedition. Following this, she worked as a postdoctoral researcher investigating drug induced mitochondrial toxicity in the context of hypoxia in the group of Dr Andrew Murray at the University of Cambridge and in collaboration with GlaxoSmithKline and AstraZeneca.
James J. Yu
Ph.D. Student, Biomedical Sciences Graduate Program
James is a PhD student interested in identifying genetic, metabolic, and physiological variation in high-altitude populations that are adaptive in hypoxic (both chronic and intermittent) environments. He is interested in utilizing techniques and tools such as CRISPR, metabolomics, and hypoxic ventilatory response to investigate variation within these populations. He graduated from Duke University in 2016 and serves as a Medevac pilot and Platoon Leader in the Army Reserves. In his free time, he enjoys rock climbing and surfing.
Wanjun Gu
Research Data Analyst
Wanjun graduated from UC San Diego with majors in Chemical Engineering and Economics. He is interested in hypoxia physiology and population genomics. He is currently doing genomic, transcriptomic, and metabolomic analysis on Tibetans, Han Chinese, and Andeans.

Ph.D. Student, Department of Bioengineering
Mitchell is a Ph.D. student interested in identifying genetic mutations found in populations living in extreme conditions and linking those mutations to adaptive phenotypes. He seeks to apply engineering techniques to develop ways to maintain biological function despite environmental stress. Mitchell graduated from UCSD in 2020 with a B.S. in Bioengineering.
Caroline GaetaGraduate Research Assistantcgaeta@ucsd.eduCaroline graduated from UC San Diego (UCSD) in 2020 with a major in Human Biology. She is currently a Biology Master’s student in the BS/MS Program at UCSD. Her research focuses on hypoxia, Chronic Mountain Sickness, and epigenetics modifications such as DNA methylation. After graduating from her Master’s program, Caroline plans to apply for dental school in the hopes of becoming an orthodontist in the future. Outside of academia, Caroline enjoys baking, traveling, and spending time with her cat and two dogs.
Mikael Fakhoury
Graduate Research Assistant
Mikael is a Biology Masters student and graduated in 2020 as a Human Biology major. He is interested in studying the inflammatory response involved in Chronic Mountain Sickness and intermittent hypoxia. After he obtains his Master’s in Biology, Mikael plans to continue onto medical school. Outside of academia, Mikael is an advisor for Global Medical Training at UC San Diego and enjoys helping the less fortunate in his community and abroad. His interests include hiking, rock climbing, and overall adventure. During the pandemic, he has focused on working out, reading, and overall self-care.
Graduate Research Assistant
Jack is interested in both the biological and computational components of cellular hypoxia as well as adaptations in genomics of high altitude populations and how these physiological and genetic changes affect their lives. In addition, he hopes to learn more about how current bioinformatics tools can contribute to the discovery of new knowledge in regards to cellular hypoxia. Outside of lab and classes, he enjoys playing the cello.
Jennifer Reeves
Undergraduate Research Assistant
Jennifer is a Human Biology major interested in physiological and genetic aspects of hypoxia with a focus on recurring biological pathways and how certain mutations induce phenotypic variation in high altitude populations. Outside of academia and personal endeavors, she enjoys cooking, boxing, and traveling.
Marco Bauk
Undergraduate Research Assistant
Marco is a fourth-year Human Biology major interested in the physiological responses to hypoxia in high-altitude populations. He is narrowing his focus on whether certain functional variants of endothelin receptor genes are associated with specific medical conditions in Andean populations. Marco occupies his free time with water polo, ship restoration on the USS Midway, and sailing.
Jeevan Singh
Undergraduate Research Assistant
Jeevan is a third-year Human Biology major with a minor in Chemistry. He is interested in investigating the body’s response to hypoxia at the molecular level and understanding how variation between populations can be used to advance precision medicine. His current research focuses on investigating functional variants of genes related to the Andean response to hypoxia using gene-editing technology. Outside the lab, Jeevan is a safety officer for the UCSD club lacrosse team and a member of AED. After graduating from UCSD, he plans to attend medical school. A San Diego native, Jeevan enjoys spending his free time playing lacrosse, mountain biking, and surfing.
