Post-doctoral fellowship position in genomic instability, DNA replication and Recombination in the Campbell Lab

Cancer cells are undergoing replication stress due to oncogene activation or ablation of tumor suppression.  Recent studies point to stalled replication forks as major culprit in generating mutation and genome rearrangement that correlate with tumor progression.  The aim of our studies is to understand events at stalled DNA replication forks.  Projects range from delineation of the delicate balance of remodeling, degradation and restart at stalled replication forks involving helicases and nucleases to characterization of small molecule inhibitors of one of the major players in replication fork stability.  These inhibitors have applications in killing replication stressed tumor cells, in sensitizing tumor cells to chemotherapies and radiation therapies that interfere with replication fork progression, and synergizing with other DNA repair inhibitors in combinatorial therapies.  A background in the DNA damage response, repair, recombination, and/or DNA replication is preferred but not essential.

Candidates with a record of publication in peer–reviewed journals and expertise in human cell culture, shRNA and siRNA knockdowns, IPs, westerns, cell line derivation, standard molecular biological techniques and cell biological techniques (e.g. immunfluorescence, cell cycle, and chromosome analysis) are sought.  Experience with pulse-labeling of DNA, DNA fiber tracking, protein expression and/or purification, in vitro assays of enzymes of DNA metabolism, mouse xenograft experiments, and/or bioinformatics is preferred but not required.

To apply:  Please send a detailed curriculum vitae, a short statement on future research goals, and names and contact details for three references, including your PhD supervisor, to Prof. Campbell at


Two Postdoctoral Scholar Positions in the Ondrus Lab

The Ondrus lab is seeking postdoctoral scholars to investigate specific aspects of metabolic control within the Hedgehog signaling pathway.  We employ a unique, interdisciplinary combination of small molecule synthesis, protein biochemistry, and genetic screens to elucidate mechanisms of endogenous metabolite signaling.  Our ultimate goal is to define actionable metabolic regulators as therapeutic targets for Hedgehog pathway-driven congenital diseases and cancers. For more information, please see our website at

Applicants should send a one-page cover letter describing their specific interests and capabilities for the proposed work, as well as their future career plans.  Applications must also include a CV, a description of past work (one page maximum), and three contacts for letters of reference.  All materials can be sent directly to Prof. Ondrus at

Postdoctoral Scholar Position in Genetic Screening

We are seeking individuals to conduct pooled CRISPR/Cas9 screens targeting metabolic pathways involved in Hedgehog signaling.  This is a unique opportunity to use high-throughput screening to investigate metabolic regulation.  Applicants must have a PhD in cell, molecular, or systems biology, an established publication record, and strong leadership capabilities.

We welcome applicants in the following areas:

·       Individuals with extensive experience in mammalian cell culture involving CRISPR/Cas9, including basic cloning techniques, lentivirus production, guide validation and optimization, DNA isolation, and next generation sequencing.  Experience with flow cytometry is beneficial but not required.

·       Individuals with expertise in computational/systems biology to participate in guide design and data analysis, including next-generation sequencing strategies, statistical evaluation of results, and generation of genetic interaction maps.  Programming ability in Java, Python, and/or MATLAB/R is required.

Postdoctoral Scholar Position in Protein Engineering

We are seeking individuals with a background in structural biology to study posttranslational modifications of Hedgehog pathway proteins.  This position involves investigating novel aspects of protein biochemistry and developing tools to study Hh pathway morphogenesis.  Available research areas include protein structural characterization, high throughput mutagenesis screens, molecular dynamics simulations, and development of chemical genetic tools to study morphogen gradients in vivo.  Applicants must have a PhD in biochemistry or structural biology, an established publication record, and the ability to work both independently and collaboratively.  Extensive familiarity with techniques in molecular biology and in vitro protein expression is required, along with experience in x-ray crystallography, cryo-electron microscopy, or NMR analysis.


Postdoctoral Scholars in Aerosol Science

The California Institute of Technology (Caltech) invites applications for Postdoctoral Scholar appointment in aerosol science.  The successful candidates will work in Prof. Rick Flagan's group on developing new methods for measurement of aerosol particles in the low nanometer size range (down to 1 nm diameter), and the application of those methods to the study of atmospheric new particle formation and growth, and of human exposures to ultrafine particles.  Applicants must have a Ph.D, preferably in engineering, chemistry, physics, or a related field.  Research experience with aerosols and aerosol measurement is required.  The research may involve both laboratory work at Caltech, and studies in off-campus laboratories or field measurement sites.  The successful candidate should have excellent communication skills.  Salary and benefits are highly competitive.  While the start date for the positions is flexible, there is a strong preference for early appointments.  Interested individuals should send a CV, list of publications, a brief statement of research interests to  They should also arrange for three letters of recommendation to be sent directly from scientific references who are familiar with the candidate's research experience and personal qualifications to the same e-mail address.
Postdoctoral Fellowship in Microfabrication
The California Institute of Technology (Caltech) invites applications for a postdoctoral research fellowship in microfabrication. The successful candidate will work in Prof. Rustem Ismagilov's group to develop mass-producible and user-friendly microfluidic devices that can be used to count molecules in limited-resource settings. These devices should revolutionize in vitro diagnostics for global health and enable breakthroughs in studies of single molecules. Applicants must have a Ph.D., preferably in mechanical engineering or a related field. Experience and knowledge in thermoforming, hot embossing, and CNC machining are required. Experience in microfluidics, 3D printing processes, simulation of molding processes, or injection molding is preferred. The successful candidate should have excellent communication skills. Salary and benefits are highly competitive. While the start date for the position is flexible, there is a strong preference for early appointments. Interested individuals should send a CV, list of publications, a brief statement of research interests, and have three letters of recommendation sent directly from scientific references who are familiar with the candidate's research experience and personal qualifications to
