Semlow Lab Postdoctoral Scholar
Postdoctoral positions are available in the laboratory of Daniel Semlow in the Division of Chemistry and Chemical Engineering at the California Institute of Technology. The Semlow lab is broadly interested in understanding the molecular mechanisms of DNA damage and repair. We are seeking motivated fellows that will undertake biochemical, genetic, and analytical approaches to elucidate novel pathways in DNA repair. At Caltech, fellows will contribute to an outstanding intellectual environment and enjoy access to state-of-the-art resources and facilities.
Candidates should have a PhD in biochemistry, molecular biology, chemistry or related field and strong record of research productivity. Experience in CRISPR/Cas9 screening or mass spectrometry is a plus, but not required.
Interested applicants should send a CV with a summary of research interests and contact information for three references to Dr. Daniel Semlow (firstname.lastname@example.org).
Scientist II, Downstream Process Development
Codiak is driven by a belief that the most innovative medicines are found at the intersections of scientific fields and that problem-solving across disciplinary boundaries is necessary to be a leader in bionanoparticle therapeutics. The Downstream Processing group at Codiak is seeking a talented, creative, and passionate candidate motivated to bring impactful therapeutic modalities to patients with unmet medical needs. The group prides itself on integrity and collaboration while almost always finding time to have fun at work.
The Scientist will develop and optimize the company's novel exogenous exosome/synthetic nucleic acid loading platform. The successful candidate will be highly motivated, thrive on increasing levels of responsibility, and have a demonstrated capability to drive science in a fast-paced environment. Responsibilities will include providing technical/scientific expertise and leadership in all areas of drug process development such as loading, cleanup, filtration, and formulation. Additional responsibilities will include assisting in the development of processes for the purification of exosomes.
