THREE POSTDOCTORAL RESEARCH ASSOCIATE POSITIONS, GENOMIC ANALYSIS OF HEAT STRESS TOLERANCE DURING TOMATO POLLINATION

Brown University, University of Arizona, Wake Forest University

The Department of Molecular Biology, Cell Biology and Biochemistry is seeking a Postdoctoral Research Associate to join the laboratory of Mark Johnson. Brown University is committed to fostering a diverse and inclusive academic global community; as an EEO/AA employer, Brown considers applicants for employment without regard to, and does not discriminate on the basis of, gender, sex, sexual orientation, gender identity, national origin, age, race, protected veteran status, disability, or any other legally protected status. 

Review of applications will begin immediately and will continue until the position is filled or the search is closed. Please apply via Interfolio.

Three postdoctoral research positions are available as part of a collaborative interdisciplinary NSF Plant Genome Research Program funded project that focuses on using modern genomic tools and latest RNA-seq technologies to develop heat-tolerant tomato varieties. Plant reproduction, especially pollen tube elongation and fertilization, are essential for seed and fruit production. However, this critical process is also highly vulnerable to heat stress. Dramatically reduced seed and fruit yield occur when otherwise healthy plants experience heat stress only for a few hours during this critical process. Targeted genetic changes are one way to equip plants to combat heat stress from rising temperatures due to climate change. Tomato is an excellent model plant to investigate and identify the molecular mechanisms that underlie heat tolerance during reproduction, as pollen development in this species is heat sensitive and it is replete with excellent genetic and genomic resources.

These three post-doctoral researchers will be part of a collaborative, interdisciplinary team of researchers in five laboratories at four institutions examining the genomics of tomato pollen tube growth to generate heat-tolerant tomato varieties. The chosen candidate(s) will be part of either the Johnson lab at Brown University, the Palanivelu lab at the University of Arizona, or the Muday laboratory at Wake Forest University. These post-doctoral researchers will benefit from a supportive collaborative research experience that emphasizes mentoring by a team of co-PIs with diverse expertise. This group includes Dr. James Pease (Wake Forest University) and Dr. Ann Loraine (UNC-Charlotte) whose expertise and focus is on developing bioinformatic and computational approaches for large scale data analysis. The three postdoctoral positions will each have a unique focus that takes advantage of the resources developed by the group to study reproductive thermotolerance using in vitro and in vivo studies of mutants, transgenic plants, and natural variants with altered metabolism that reduces or enhances thermotolerance. Experimental approaches include genomic, genetic, cell biological, and biochemical analyses. Applicants for all three positions should send a letter of interest, CV, and contact information for three referees to Gloria Muday at muday@wfu.edu.
