LEC Postdoctoral Fellows will be an essential part of the Living Earth Collaborative and are expected to develop an independent research or conservation program that engages with multiple members of the Living Earth Collaborative Community—projects that involve LEC Biodiversity Fellows.

The objective of our research is to understand how the collection of red/far-red light-absorbing photochromic photoreceptors - phytochromes - enable perception of light by plants and microorganisms through analysis of their 3D structures using atomic level methods such as x-ray crystallography and cryo-electron microscopy. The advertised position will aid in these efforts by expressing and purifying recombinant wild-type and mutant versions of these photoreceptors, assist in their biophysical and biochemical analyses, and help develop phytochrome samples for subsequent structural studies.

The Department of Biology at Washington University seeks a colleague working in Molecular, Cellular, & Developmental Biology to fill a tenure-track faculty position at the Assistant Professor level. We are interested in candidates who employ innovative approaches to conduct research in one or more of the following areas - biochemical systems, plant science, developmental controls, and/or genome biology.

A full-time position that combines the roles of lab manager and surgical technician requiring good communication and organizational skills, and a willingness to learn and implement new techniques. The successful candidate will be able to direct/coordinate lab business independently, and will be expected to design and implement experiments, analyze data, and troubleshoot as needed. The Hengen Lab is a dynamic, fast-paced, and interdisciplinary group. Daily tasks are highly variable, and require the manager to be involved in/aware of many projects, people, and developing directions in the Lab. This position requires extensive communication with individuals outside the lab such as the accounting department, HR, IACUC, and DCM staff, as well as communications with sales reps from companies from which supplies are purchased.

Postdoctoral position on amoeba social evolution and/or amoeba–bacteria symbiosis: This position is for research in the Queller-Strassmann group. We focus on the evolution of interactions, especially in the social amoeba Dictyostelium discoideum. This has become a model system for the evolution of cooperation and conflict and the transition to multicellularity. We are also working on its symbiotic bacterial partners sometimes confer a farming advantage but also impose costs.

This is a full-time, temporary position of up to 5 months. The position is scheduled to begin around August 2019. The technician will conduct plant ecology research in the field and laboratory and work closely with Jonathan Myers on tasks related to data collection, data entry, and project maintenance. The position will be based in the Department of Biology and the Tyson Research Center.

A full-time position for a research assistant requiring good communication and organizational skills, and a willingness to learn new techniques. The individual must be able to work independently, will be expected to design and implement experiments, analyze data and troubleshoot as needed using our study organism Dictyostelium discoideum. Consequently, there are potential opportunities to co-author scientific publications and present at scientific meetings. Research will use behavioral, genetic, genomic, microbiological, cell biology, molecular biology, and field techniques. A description of the many exciting projects ongoing in our laboratory may be found on our website (http://strassmannandquellerlab.wordpress.com).

A full-time position for a research technician in the area of molecular genetics and membrane protein biochemistry. This position requires good communication and organizational skills, ability to work independently as well as within a team, and a willingness to learn new techniques.

A postdoctoral position is available starting January 1, 2020 in a research laboratory at Washington University in St. Louis. Research in the lab addresses links between the environment, cell growth, cell cycle progression and antibiotic resistance using a wide range of techniques.

A Postdoctoral Research Scientist position is available immediately to study the phytochrome family of photoreceptors at the structural and biochemical levels to understand how they transition between their spectrally and conformationally distinct inactive Pr and active Pfr states.
