U.S. Department of Interior Commission Gains New Member

Grace Bulltail, Ph.D., P.E., has been appointed to the Not Invisible Act Commission, a joint effort between the U.S. Department of the Interior and the U.S. Department of Justice to identify, report, and respond to instances of missing and murdered Indigenous people and human trafficking.

In this role, Dr. Bulltail will serve with tribal, state, and local law enforcement representatives, tribal judges, and health care and mental health care professionals who have experience working with survivors of human trafficking and with family members of missing and murdered Indigenous people. She holds a B.S. in civil and environmental engineering from Stanford University and completed master’s degree programs at Montana Technological University and Columbia University. She holds a Ph.D. in biological and environmental engineering from Cornell University and is a licensed professional engineer.

Dr. Bulltail is a member of the Crow tribe and a descendant of the Mandan, Hidatsa, and Arikara tribes of Fort Berthold, North Dakota. She is an assistant professor in the Nelson Institute Center for Sustainability and the Global Environment and an affiliate in the department of biological systems engineering, both at the University of Wisconsin–Madison. She was invited to submit her nomination for the commission based on her academic research and practical experience with tribal resource sovereignty, natural resource management, and environmental justice on tribal lands.

Her appointment is particularly meaningful because she lost a loved one under suspicious circumstances. Her 18-year-old niece went missing in 2019 and was later found dead in Hardin, Montana, a town bordering the Crow reservation. Dr. Bulltail and her family have launched their own investigation because the incident has not been investigated as a homicide as determined by the Big Horn County law enforcement office.

The Not Invisible Act, passed by Congress in 2020, is intended to address the crisis of missing, murdered, and trafficked Native people by involving law enforcement, tribal leaders, federal partners, and service providers.

AISES Issues Annual STEM Awards

The American Indian Science and Engineering Society (AISES), which advances Indigenous people in STEM professions, has issued its annual awards recognizing the significant contributions of Alaska Native, Native Hawaiian, Pacific Islander, First Nations, and other Indigenous people to various STEM fields.

Among the AISES’s 2022 awardees are Deneen Hernandez, Ph.D., who received the Professional of the Year award; Angela Teeple, who received the Most Promising Engineering or Scientist award; Sonia Ibarra Marquez, Ph.D., who received the Indigenous Excellence award; and Rachel Yellowhair, who received the Blazing Flame award.

Dr. Hernandez, recipient of the Professional of the Year Award, is enrolled in the Seneca Nations of Cattaraugus Reservation and has served in law enforcement for 28 years. The award recognizes leadership and technical achievement across all categories. She is a forensic examiner for the Federal Bureau of Investigation Laboratory in the Cryptanalysis and Racketeering Records Unit. In this role, she examines suspected gambling records (such as bookmaking and gambling devices) to determine if they are illicit. She also examines and deciphers codes and symbols that might identify suspected criminal and gang activity. She is one of two Native American forensic examiners in the FBI lab.

Prior to her work with the FBI, Dr. Hernandez served as a forensic examiner and investigator in the National Indian Gaming Commission and as a senior inspector with the New York State Racing and Wagering Board. She also served as a tribal officer for the Seneca Nation. Earlier Dr. Hernandez served for many years as an adjunct professor teaching criminal justice courses and was a forensic instructor at the University of Maryland University College (now University of Maryland Global Campus) and Jamestown Community College, respectively. She continues to visit schools and colleges to promote careers in STEM and forensic science.

Dr. Hernandez holds a B.A. in political science from the State University of New York at Fredonia; an M.A. in criminal justice from Buffalo State College; and a Ph.D. in public service leadership from Capella University. She is a national trainer for the National Partnership for Careers in Law, Public Safety, Corrections, and Security and volunteers with the Forensic Outreach Program in London.

The AISES Most Promising Engineer or Scientist Award this year was presented to young professional Angela Teeple, who originates from Gnoozhekaaning, or Bay Mills Indian Community, a tribe of 1,000 in the Upper Peninsula of Michigan. Teeple serves as a water contamination researcher, Indigenous law consultant, and nuclear engineer for the Air Force Nuclear Weapons Center. As part of a close-knit team of seven, whose mission is to analyze nuclear effects on aircraft, environments, and personnel for the Air Force, Teeple directs analyses and manages software handling critical nuclear data. Her contributions have earned several accolades and awards.

Teeple is also a member of the Indigenous Barrier Analysis Group for the entire Air Force that identifies obstacles Indigenous people in the Air Force face and creates initiatives that combat these found barriers.

Apart from her work at the nuclear center, she contacts tribes offering water testing services and legal advice. In 2017, she performed neutron activation analysis (NAA) on her tribe’s water sources and discovered contaminants not previously known since federal water testing only detects specific elements. NAA testing, however, indicates the full spectrum of elements in a sample.

This discovery left unanswered questions about how tribes pursue clean water once contamination is detected. This prompted Teeple to pursue a Master of Legal Studies in Indigenous People’s Law and Policy from The University of Oklahoma. With her research capability and legal background, she now provides NAA testing and natural resource law mentoring for tribes.

Teeple holds a B.S. in mechanical and nuclear engineering from Kansas State University. She is currently pursuing a Ph.D. in medical physics from the University of Minnesota Medical School, where she is a Science, Mathematics, and Research for Transformation (SMART) Scholar.

The AISES Most Promising Engineer or Scientist Award recognizes a professional engineer or scientist with less than five years of workforce experience after earning a professional degree. The candidate’s early technical contributions must indicate a promising career.

AISES Blazing Flame Award honoree Rachel Yellowhair is a member of the Navajo Nation. Born in Phoenix, she grew up on the Navajo Reservation in Kayenta, Arizona. She holds a B.S. in mathematics from The University of Arizona and a master’s degree in management information systems from the University of Phoenix.

Yellowhair has been an active member and volunteer with AISES for more than 25 years and became an AISES Sequoyah lifetime member in 2017. She also volunteers with the Arizona Trail Association by providing office support each month.

She began her career with Raytheon Missile Systems as an IT systems administrator. Subsequent positions of increasing responsibility followed, including serving as a technical individual contributor to leading teams. Currently Yellowhair serves as senior manager of the West Region Raytheon site services, where she oversees all digital technology operations and site service activities in the west region of the United States. Her team of two design and technology site leads and five technical professionals supports several thousand employees in seven businesses and remote locations.

Yellowhair interacts and coordinates with resource management division, design and technology service owners, and other key stakeholders on projects and strategic initiatives. She is also involved in business location strategy with regards to growth and closures, and design and technology initiatives rollouts and operations support.

AISES presents the Blazing Flame Award to an individual who “blazes” a path for Indigenous people in STEM careers. This award recognizes individuals with 10 or more years of professional experience with significant accomplishments in advancing STEM education and careers.

The AISES Indigenous Excellence Award acknowledges an individual who has done substantial work for 10 or more years to advance programs and opportunities for Indigenous students and professionals within their Indigenous communities and or in support of Indigenous people at the national level.

Awardee Sonia Ibarra Marquez, Ph.D., is Apache, Caxcan, Mexican, and Latina and grew up in the traditional territories of the Nomlaki people in Northern California. Her parents migrated to California from México. She holds a B.S. in marine biology from Humboldt State University with minors in leadership and scientific and recreational Scuba diving. Thereafter she worked as a scientific diver and field researcher in the Philippines, the U.S. Virgin Islands, Belize, and the southern California Channel Islands. She continued her graduate work at the University of Alaska Fairbanks, earning a Ph.D. in fisheries. She was also awarded two National Science Foundation grants. Her work has focused on co-creating a project with tribes and Indigenous youth in Southeast Alaska to weave Indigenous and Western knowledge systems and document a holistic picture of the relationship between Indigenous people, sea otters, and shellfish that has largely been ignored by marine ecologists.

Dr. Ibarra Marquez currently serves as the program coordinator for Tamamta (“all of us,” an Indigenous-centered graduate training program at the University of Alaska Fairbanks). The program seeks to strengthen the connection between Indigenous and Western sciences to transform graduate education, research, and resource management in fisheries and marine sciences to encourage more Native Alaskans to enter this field of study.
