We are seeking a motivated M.S. or Ph.D. graduate student to join a recently funded project investigating the role of microorganisms in soil pedogenesis the in lunar and Martian regolith systems and how space flight alters soil microbial function. The successful candidate will help characterize changes in microbial community composition and investigate how microorganisms influence the biological and biogeochemical processes involved in soil formation. This position offers an exciting opportunity to contribute to emerging research at the intersection of soil science, microbiology, astrobiology, and space agriculture, with potential implications for sustainable food production and long-duration human exploration beyond Earth.

Research Responsibilities

The graduate student will work collaboratively with a team of graduate researchers and faculty on several aspects of the project, potentially including:

• Microbial community analysis: Characterize microbial communities associated with regolith-based and hydroponic systems using bioinformatics and molecular or genomic approaches.
• Experimental research: Participate in greenhouse, growth chamber, and laboratory experiments investigating microbial interactions with lunar and Martian regolith simulants and plant-growing systems.
• Spaceflight-related research: Analyze soil and regolith samples associated with experiments conducted in space to investigate how spaceflight conditions influence microbial communities and soil-related processes.
• Data analysis and interpretation: Integrate microbial community data with experimental and biogeochemical measurements to understand microbial contributions to soil formation and the development of biologically active regolith.
• Scientific communication: Contribute to research presentations, scientific manuscripts, and collaborative publications.

Mentorship and Research Environment

The student will join a collaborative research team consisting of one to two other graduate students working on related aspects of the project. The student will be supervised primarily by Dr. Peyton Smith, with additional guidance and collaboration from Principal Investigator Dr. Howe and Co-Principal Investigator Dr. Coker.

The research team will provide opportunities to develop expertise in soil science, microbial ecology, bioinformatics, experimental design, and interdisciplinary research. The student will also have opportunities to contribute to publications and present research findings to the broader scientific community.

Funding and Benefits

The position includes a competitive research assistantship package providing:

$32,000 annual stipend
Tuition and fees
Health insurance

The position is based in the Department of Soil and Crop Sciences at Texas A&M University in College Station, Texas, with an anticipated start in Spring 2027.

How to Apply or Inquire

Interested students should contact Dr. Peyton Smith at peyton.smith@ag.tamu.edu to express interest and learn more about the position. Please include a brief introduction describing your academic background, research interests, and relevant experience in bioinformatics, laboratory research, or experimental studies. A CV is encouraged. We look forward to hearing from prospective students interested in advancing our understanding of how microorganisms can contribute to soil formation and enable future agriculture in space!
