Through learning scholarship and practice students gain the experience knowledge and courage they need to tackle big challenges in the real world and guide diverse communities and organizations.

About the College of Natural Sciences and Mathematics

The college is home to five academic departments: Biological Sciences Chemistry and Biochemistry Geography and the Environment Mathematics and Physics and Astronomy. The college offers over 30 degrees ranging from Bachelor of Arts to Doctor of Philosophy as well as having many active research labs funded through extramural sources.

About the Department of Biological Sciences

The Department of Biological Sciences integrates faculty postdocs and graduate students from a range of sub-disciplines ranging from Cell and Molecular Biology to Genomics Ecology and Evolutionary addition to core programs members of the department also participate in the NSM college-wide Molecular Biophysics graduate training program the Knoebel Institute for Healthy Aging and the DU Evolution Ecology and Biodiversity supergroup (DUEEBs). As part of the larger front-range scientific community research in the department is supported by core facilities at DU and at neighboring institutions (University of Colorado School of Medicine and University of Colorado Boulder).

Position Summary

The Nichols Lab at the University of Denver (DU) is seeking a Postdoctoral Research Associate. Our research uses the freshwater sponge Ephydatia muelleri (Porifera) as a model system to uncover the cellular foundations of multicellularity in animals.

We focus on two main areas:

1. Cell adhesion and epithelial evolution investigating how mucosal epithelia are assembled and maintained and how these processes inform the origins of complex tissues in animals.
2. Innate immunity and hostmicrobe interactions studying the genetic and cellular mechanisms by which sponges distinguish between pathogenic and prey bacteria and exploring the evolutionary origins of animal immune systems.
   Our work integrates experimental cell biology molecular genetics and evolutionary approaches with an emphasis on developing Ephydatia as a tractable system for probing fundamental questions in cell biology and evolution.
   The preferred candidate will hold a PhD in Biology (evolutionary or molecular/cell) or a related field (e.g. biochemistry). Applicants should have experience in wet-lab methods (e.g. PCR molecular cloning microbiology protein expression and purification) and basic computational techniques (e.g. R gene expression analysis or implementing academic software packages).

This is a full-time 12-month appointment with the possibility of annual renewal based on performance and continued funding. The start date is flexible.

Essential Functions

The postdoctoral associate will play an active role in advancing the Nichols Labs research program. They will be expected to learn and master laboratory techniques for working with the freshwater sponge Ephydatia muelleri and contribute to troubleshooting protocol optimization and development of new experimental approaches. The position involves handling the BSL-2 pathogen Legionella pneumophila requiring adherence to strict biosafety practices.

The postdoc will also contribute to the mentorship and training of graduate students undergraduates and technicians and will collaborate closely with other members of the lab. They will present research at conferences contribute to the preparation of manuscripts and assist in writing grant proposals. Additional responsibilities include maintaining detailed laboratory records ensuring experimental reproducibility and developing increasing independence in project design and execution.

This position emphasizes both scientific contribution and professional development. The postdoc will be encouraged to pursue career-building opportunities including networking workshops and fellowship applications with guidance and support from the PI.

Knowledge Skills and Abilities

• Ability to design execute and analyze independent research projects.
• Strong written and oral communication skills including the ability to publish in peer-reviewed journals and present at scientific conferences.
• Proficiency in fundamental molecular biology and microbiology techniques (e.g. PCR cloning protein expression microbial culture).
• Familiarity with computational tools for data analysis including differential gene expression analysis and the use of R or related programming languages.
• Ability to collaborate effectively in a team environment and to mentor junior researchers.
• Commitment to rigorous data management reproducibility and adherence to biosafety protocols.

Required Qualifications

• PhD in Biology Biochemistry or a related field completed prior to the start date.
• Demonstrated ability to conduct independent high-quality research.

Preferred Qualifications

• Expertise in molecular cellular or microbial biology.
• Experience with computational biology approaches including analysis of large-scale sequencing data.
• Background and strong interest in evolutionary biology and hostmicrobe interactions.

Working Environment

• Standard office and laboratory environment.
• Optional fieldwork may occur at lakes and streams.
• Optional fieldwork activities may include wading snorkeling or SCUBA diving in cold water with overnight stays in hotels motels or other accommodations as appropriate.
• Fieldwork if undertaken typically occurs during the fall or winter seasons for a total of approximately one week per year.
• The position may involve moderate to high stress at times due to unexpected interruptions deadlines and multiple ongoing projects.
• The noise level in the work environment is usually quiet to moderate.

Physical Activities
