Fatigue Countermeasure Laboratory Director

> Awards/Publications/CV

Dr. Flynn-Evans received a PhD in Health and Medical Science from the University of Surrey (Guildford, UK), with a focus in circadian physiology, and an MPH in Clinical Effectiveness from Harvard School of Public Health (Boston, MA), with a focus in biostatistics. She was awarded a pre- and post-doctoral fellowship from the Harvard Medical School Division of Sleep Medicine training program in Sleep, Circadian and Respiratory Neurobiology and was an Instructor in Medicine at Harvard Medical School prior to joining NASA.

Dr. Flynn-Evans' research involves investigating and deploying cutting-edge science and technology to manage and mitigate fatigue in spaceflight, aviation and other high-pressure occupations. Her approach involves conducting laboratory experiments to investigate the impact of interventions on sleep and circadian physiology and to evaluate new technologies. Once new intervention strategies and tools have been evaluated under controlled conditions, her team conducts field research to determine how new intervention approaches translate to operations. This combination of laboratory and field research allows her team to directly translate basic science findings into practical solutions for mitigating fatigue-related performance error in occupational cohorts.

Dr. Flynn-Evans has published numerous peer-reviewed journal articles and has been an invited speaker at many national conferences and meetings. In 2016, she was awarded the NASA Early Career Achievement Medal.

Zach joined the Fatigue Countermeasures Lab in the Fall of 2018 as a contractor from the San Jose State Research Foundation, who was converted to civil servant from the NASA Pathways program in the Fall of 2019. He is currently pursuing his MA in Research and Experimental Psychology at San Jose State University. During his time at Ames, he aided in various experiments lead by fellow team members, as well as conducted his thesis for his graduate program. The topic for his thesis was evaluating mission control operations from a fatigue risk management perspective, in hopes of providing recommendations to future NASA space missions.

Summer Internships Header
   
The Fatigue Countermeasures Laboratory provides a unique opportunity for undergraduate students to engage in a variety of research projects. These summer internships last 10-12 weeks beginning in June and ending in August.

This summer we will be conducting a study to evaluate countermeasures to help people sleep and to help improve alertness. When individuals work in safety-sensitive occupations, such as in spaceflight and long-haul aviation, sleep opportunities may not occur at optimal times. Similarly, it may be necessary for such individuals to perform cognitively demanding tasks following insufficient sleep and during the night. As a result, people in safety sensitive occupations need tools and strategies that they can use to help them fall asleep and stay asleep and to maintain alertness when they are awake. To test such tools and strategies, we will study participants who will live in our laboratory for a few days. While in the lab, participants will wear electrodes to measure their brain activity while they are awake and asleep, they will provide saliva and urine samples so that we can assess their hormones, and they will take frequent cognitive tests so that we can assess their alertness and performance.

Interns will assist with all aspects of data collection during these overnight sleep studies including preparing study materials, interacting with study participants, applying electrodes, monitoring sleep and waking, administering cognitive tests, and collecting biological specimens. The intern will also assist with data analysis and processing of cognitive performance and sleep data. Importantly, interns will be required to work overnight and weekend shifts (but never more than 40 hours a week) during the internship.

Each intern will have the opportunity to attend lectures and seminars on a variety of topics at NASA Ames Research Center. Interns will also participate in weekly lab meetings and will present a journal club article once during the summer. Finally, each intern will choose a topic to investigate (this could be an analysis of existing data or a literature review on a new topic) and will write an abstract and present a poster at NASA at the end of the summer.

No prior experience is necessary; however, the best candidates will be open to new experiences and learning new things, able to work independently and with a team, punctual, and reliable.
