Would you like to join a collaborative lab with broad research interests and committed to you career development? We are offering a unique opportunity to join our lab to carry out cutting-edge research broadly related to the topic of signal transduction via G protein-coupled receptors (GPCRs). Our laboratory is in a phase of expansion with multiple active NIH-funded grants to provide stable support and freedom of operation for personnel. You would join a dynamic team of international researchers (PhD students and other postdocs) with an interest in collaborating and helping each other. Dr. Garcia-Marcos seeks to mentor the next generation of scientists by providing abundant one-on-one time and the support required to transition into subsequent career stages, including establishing their independent research programs. The laboratory has an excellent track record of facilitating the transition of former postdoctoral fellows to competitive positions.     

 

Position conditions- We are located at the heart of Boston, a scientifically and culturally vibrant location. The salary can be negotiated, but would always be above NIH salary scale and a sign-on bonus to mitigate relocation expenses would also be provided. Postdoctoral researchers at our institution have the same benefits as staff personnel, including health/ dental plans, retirement plan, and dependent care/ healthcare flexible spending accounts, among others. 

 

Lab interests & ongoing projects-

 

  • Defining new mechanisms of signal transduction via GPCRs and heterotrimeric G proteins across scales, from molecules to whole organisms. Bacteria, yeast, mammalian cells, frogs, fish, mice. Non-canonical heterotrimeric G protein signaling in epithelial planar cell polarity, cilia, and development Development of optical biosensors, synthetic gene circuit reporters, and chemogenetic tools to detect and manipulate the signaling activity of heterotrimeric G proteins Characterization and pharmacological targeting of non-canonical heterotrimeric G protein signaling in cancer metastasis Biochemical, functional and structural characterization of atypical G protein signaling complexes.

 

 

Some representative publications are listed at the end of this advertisement and a complete list of publications is in: https://www.ncbi.nlm.nih.gov/myncbi/1ZIXmzi80H8Q6/bibliography/public/

 

Candidate’s qualifications & expertise-

 

The candidate should have at least one of the following technical skillsets. Priority will be given to candidates with a strong background in cell biology and imaging, and/or aquatic model organisms:

 

  • Extensive experience with fluorescence microscopy and image analysis. Live-cell microscopy desirable. Xenopus and/or zebrafish experience. Egg microinjections and other general aquatic model procedures. High proficiency in cell culture. Viral gene delivery, generation of stable cell lines, different types of cells (e.g., transformed and non-transformed, primary cell cultures), signaling assays. Basic knowledge of mouse colony maintenance desirable. Fast paced in molecular biology (cloning by Gibson assembly, Golden Gate, etc), and knowledge of protein purification (batch, FPLC) and protein binding assays (pulldowns, immunoprecipitations). Structural biology background desirable.

 

 

Please submit a cover letter with details on what project you want to pursue, a CV and names/contact for 3 reference letters. Mikel Garcia-Marcos, PhD. Professor.  mikel.garcia.marcos@gmail.com
