Katrina G. Claw, PhD
(she/her/asdzaan)
Principal Investigator
Tribe: Diné (Navajo)
My research focuses broadly on personalizing medicine, using genetic information and biomarkers for tailored treatment, in relation to pharmacogenomics as well as understanding the ethical, cultural, and social implications of genomic research with populations historically underrepresented in health research. My current research includes studying cytochrome P450 genetic variation in Indigenous communities (e.g., American Indian and Alaska Native peoples), with a focus on CYP2A6 variation in relation to nicotine metabolism and smoking cessation, as well as understanding the ways in which adaptations to diverse local environments may have impacted modern pharmacogenomic variation and evolutionary medicine. My other projects include exploring the perspectives of tribal members on genetic research and developing guidelines and policies in partnership with tribes. All of my projects strive to use a community based participatory research approach and include cultural and Indigenous knowledge.

Kendra Ferrier, PhD
(she/her)
Kendra is a post-doctoral researcher in the Claw Lab. Her research interests involve conducting personalized medicine research within and across diverse populations. Her main research project in the claw lab is assessing the relationship of epigenetic markers, genetic markers, and nicotine metabolism to improve tobacco cessation interventions in American Indian communities.

Post-Doctoral Researcher
Jack Staples, PhD
(he/him)
Jack is a Postdoctoral Fellow in the Department of Biomedical Informatics at CU Anschutz. He previously earned a PhD in Pharmaceutical Sciences and a Bachelor’s in Chemical Engineering. He also completed an industry co-op in the Bioinformatics Department at Regeneron Pharmaceuticals, Inc. Jack is working on developing and applying statistical genomics methods towards characterizing the contribution of genetics, environment, and sociodemographic factors to human disease risk (e.g., cardiovascular, metabolic, autoimmune) and pharmacokinetics/pharmacodynamics of small molecule drugs and hormones (e.g., nicotine).

PhD Student, Human Medical Genetics and Genomics Program
Carissa Sherman
(she/her)
Tribe: Diné (Navajo)
​
Carissa is a PhD Candidate in the Human Medical Genetics and Genomics PhD program at the University of Colorado Anschutz Medical Campus. Her research examines pharmacogenetic variation across global populations as well as the ethical, legal, social, and cultural implications of genomics research. Her proposed thesis will focus on understanding pharmacogenetic variation within nicotine metabolism to improve tobacco cessation efforts within American Indian communities. Her mother's side is from Ganado, AZ and her father's side is from Phoenix, AZ, and Carissa is a member of the Navajo (Diné) tribe.

Research Services Senior Professional
Amanda Skenadore
(she/her)
Tribe: Diné (Navajo)
​
Ya'teeh! Kinyaa'aanii' nisli' Tl'aashchi'i' ba' shischiiin. Amanda is born for the Towering House people and born into the Red Cheek Clan and comes from a small town called Chinle, Arizona. She obtained her Masters of Public Health with a concentration in Community Health from the Colorado School of Public Health and a graduate certificate of Public Health Training for American Indian Health Professionals at Johns Hopkins Bloomberg School of Public Health. She is working with the Claw Lab on the Perspectives on Genetic Research in the Navajo Nation Project, where she is assisting in the qualitative analysis of the project.
