Employment Opportunities


Primary duties are: bacteriological and chemical analysis of water samples; sample receiving, handling, tracking, and processing; communicating with customers; receiving payments; and reporting results to customers and regulatory agencies via verbal, written, and online communication. In the event the Technical Director is unable to work in the lab for at least 30 days, this position will also be responsible for a variety of research, supervisory, and QA/QC duties normally performed by the Technical Director.

Fully Funded Positions:  PhD Students, Grant Specialist (full-time) and Post-doctoral Scholar

Seeking multiple applicants to join a large, well-funded, multi-disciplinary, and highly collaborative group of researchers working on a large-scale project: “Quantifying drivers of native and non-native aquatic species abundance and distribution in drought- and flood-prone Texas basins". The project is a collaboration between TX State University and the US Army Corps of Engineers, Engineer Research and Development Center.

Applicants should be broadly interested in working on hyporheic and/or groundwater systems and their connections to and influence on related surface systems at a variety of scales, from site to region. Research topics include but are not limited to: spatial and temporal patterns in species diversity and distribution, groundwater - surface water interactions from an ecohydrology perspective, flow and transport of nutrients, and geomicrobiological processes. Groundwater and hyporheic ecosystems in much of TX are biologically diverse, span multiple environmental gradients (e.g., T and Precip) and regions (e.g., geology and ecoregion), and provide excellent opportunities to test hypotheses across large and small temporal and spatial scales.

Our collaborative group at Texas State University, a federally designated Hispanic Serving Institution, wants to contribute to an increase in diversity (visible and invisible) in aquatic sciences and we are especially interested in applicants who share our commitment to equity and the high-quality education of students from historically underserved and systematically marginalized communities. For all positions we seek and encourage candidates from under-represented groups to apply. Applicants for all positions are encouraged to describe how they will support and contribute to our efforts build and maintain a diverse and inclusive research team. 

Grant Specialists: Two full-time (40-hour/wk) positions are immediately available for highly motivated and curious applicants. A B.S. or M.S. degree in Biology or other science field is required at the time of employment. Preferred skills and experience include: excellent quantitative, problem-solving, and communication (written and oral) skills; experience collecting, sorting, and identifying aquatic freshwater invertebrates in field and lab settings using dichotomous keys and other taxonomic literature; specimen curation; a basic to advanced working knowledge or understanding of one or more of the following: invertebrate biology in stream/hyporheic/aquifer ecosystems, MS Office (including Excel and Access), statistical packages, microscope use and imaging, and GIS. Experience with a variety of microscopes and imaging software is a plus. It is anticipated that >80% of the work related to these positions will be in the lab, though opportunities will be available to pursue advanced training in lab and field methods, and alpha taxonomy for interested applicants. For more details, and to apply to these positions, please see the following postings. The positions are identical, so an applicant need only apply for one:

Post-doctoral Researcher: One full-time post-doctoral faculty position is immediately available for a highly motivated and curious applicant with proven quantitative, problem-solving, collaboration, and communication (written and oral) skills. A Ph.D. in Biology, Environmental Science, or a related science field is required at the time of employment.

The selected candidate will be allowed flexibility to pursue specific research projects/topics of their interest (including a portion of the budget to manage) but should broadly be interested in ecohydrology of the hyporheic zone. The selected candidate will be expected to be a key part of a large and multi-disciplinary group of PIs, other post-docs, students, and technicians, and will mentor and work closely with students at all levels. Opportunities will exist to serve on graduate committees, as well as to teach specialized graduate courses in an area of the candidates expertise.

Preferred skills and experience include advanced knowledge of and/or experience with one or more of the following: invertebrate biology in stream/hyporheic/aquifer ecosystems, statistical packages such as SPSS or R, coding skills, imaging with optical and other microscopes (e.g., ), hydrology, stable isotope analysis, GIS, database management. A record of publication in peer-reviewed literature is preferred. The selected candidate will be expected to play a key role in publishing results of the research and should expect to be primary author on publications for which they played a leading role in the research.
