Academy of Bioastronautics: Postdoctoral Fellows
TRISH's postdoctoral fellowship program grants enable early career scientists to design, develop and conduct their own space-related research projects under the guidance of experienced faculty mentors. These fellows join the Academy of Bioastronautics, to share experiences and connect with seasoned spaceflight experts.

Utilizing NASA's Space Radiation Laboratory, TRISH postdoctoral fellow Frederico Kiffer and his research team will assess the effects of realistic space radiation exposures on the cognitive behavior of mice using a touchscreen-based platform. This touchscreen platform is similar to tests currently used to monitor the cognitive health of astronauts. In addition, Kiffer and his team will conduct unique social behavior experiments to evaluate the effects of space radiation exposures on aspects of social behavior and social stress resilience. And, the team will assess an experimental diet-based medication on its ability to prevent radiation-related cognitive and social complications.

Monitoring Biomarkers for Muscular Atrophy Using Nanoelectronic Chip for Astronaut Health
Watch Poster Session
Institution: NASA Ames Research Center
Mentor: Jessica Koehne, Ph.D.
View status
When muscles deteriorate, they produce a class of protein biomarkers called protease enzymes. If scientists can detect those biomarkers, they can more accurately monitor muscle atrophy. TRISH postdoctoral fellow Morgan Anderson is developing a portable, non-invasive diagnostic to monitor the progression of muscle atrophy over time. The instrument will use easy-to-use cartridges containing nine independent micro-electrodes. Each electrode will detect activity from a different biomarker, creating a “fingerprint” to monitor muscle atrophy during spaceflight. The data will help test the effectiveness of drug inhibitors.

During the long duration of space travel to Mars, there will be limited resources available for astronauts. In particular, there is not enough room to store and refrigerate an unlimited supply of all the desired medicines you might need during a multiple year mission. TRISH postdoctoral fellow Miguel Jimenez is researching the use of therapeutic microorganisms, which may allow for a renewable source of specialized medicines. Astronauts may need to take only a small dose of microbial therapeutics to accomplish the same effect of traditional pills.
Investigation of blood-based circulating biomarkers of responses to space radiation
Institution: NASA Ames Research Center
Mentor: Sylvain Costes, Ph.D.
View status
TRISH postdoctoral fellow Eloise Pariset is identifying biomarker responses to ionizing particle radiation. Pariset is exploring whether these biomarkers can sufficiently spread radiation-induced cellular damage. Pariset’s investigation will help better understand the role of the immune system’s biomarkers in the spread of radiation damage. A better understanding of how radiation damage spreads could also help create novel treatments for astronauts exploring deep space.
