Fatigue Countermeasure Laboratory Director

Phone- (650) 279-3459
Email- erin.e.flynn-evans@nasa.gov

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.

Senior Research Associate

Email- cassie.j.hilditch@nasa.gov

Cassie Hilditch joined the Fatigue Countermeasures Lab in May 2018 having undertaken post-doctoral training with the Division of Sleep Medicine at Harvard Medical School and Sleep for Science Research Lab of Brown University. Prior to moving to the US, Cassie completed her doctoral degree at the University of South Australia and worked as a fatigue research consultant in the UK. Cassie has over a decade of human sleep research experience ranging from tightly-controlled inpatient studies, to logistically-challenging field studies across a range of population groups, industries, and countries. Passionate about research with an applied focus, her primary research interests include discovering and developing countermeasures to fatigue-related performance impairment.

Research Associate

Phone- (650) 604-0968
Email- crystal.l.kirkley@nasa.gov

Crystal Kirkley joined the Fatigue Countermeasures Laboratory in May 2017. She has a background in Human Factors and Ergonomics engineering, military aviation, and construction management. She is currently pursuing a Masters of Science degree in Human Factors and Ergonomics Engineering at San Jose State University. She is interested in improvement of human performance and team dynamics in elite operational teams as they encounter isolating, confined, and extreme situations. Additionally, she collaborates within the Human Systems Integration Division on the Human Exploration Research Analog (HERA) to investigate chronic sleep restriction on cognitive performance.

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. Interns learn about sleep and circadian physiology, as well as basic research methods, including study design, subject recruitment, data collection, and basic analysis. Some internships involve learning complex tasks, such as collection of EEG or biospecimen data or learning complex analytical techniques using statistics programs such as SAS and Matlab. During the summer, interns have the opportunity to attend a lecture series on a diverse set of topics related to spaceflight and aviation. Each intern identifies a personal project for the summer and develops an abstract summarizing the results of the project. The internship culminates in a poster session at NASA.

> Check out our summer interns and their projects!


Summer internships are typically funded by an intern’s institution; however, a limited number of competitive internships have been granted by the National Space Biomedical Research Institute (http://nsbri.org/for-students/graduates-undergraduates/).

Interested interns who have funding from their institution should contact Dr. Flynn-Evans to determine availability of internships. Following this discussion, interns must apply for a position through the NASA One Stop Shopping Initiative (OSSI) program @ https://intern.nasa.gov/ossi/web/public/main/.
