We are seeking a highly motivated DNA/Aptamer Chemist to join a multidisciplinary research team developing nucleic acid-based targeting agents to treat prostate cancer. The successful candidate will focus on the design, synthesis, modification and biophysical characterization of DNA aptamers. This position would be particularly well suited to a chemist or chemical biologist interested in applying nucleic acid chemistry to translational cancer research.
Responsibilities   Design and synthesis of DNA aptamers and modified oligonucleotides.
Solid‑phase oligonucleotide synthesis, purification and quality control.
Chemical modification and functionalization of DNA, including incorporation of linkers, fluorophores, chelators and other functional groups.
Purification and analytical characterization using HPLC, LC‑MS and related approaches.
Systematic structure‑function studies using nucleotide substitutions, truncations and chemical modifications.
Development of aptamers with improved affinity, selectivity and stability.
Quantitative characterization of aptamer‑protein interactions using biochemical and biophysical approaches.
Conjugation of aptamers to imaging or therapeutic payloads.
Collaboration with protein biochemists, molecular biologists, structural biologists and imaging scientists.
Qualifications   PhD in chemistry, chemical biology, biochemistry or a closely related field.
Demonstrated experience (published work) in several of the following areas:  Oligonucleotide/DNA chemistry
Solid‑phase oligonucleotide synthesis
Nucleic acid modification and conjugation
Aptamer development or SELEX
Protein‑ligand binding assays
Bioanalytic skill including techniques such as SPR, BLI, MST, ITC, HPLC and LC‑MS
Structure‑function analysis of nucleic acids
Nucleic acid‑protein interactions

Experience with radiochemistry, chelator chemistry, structural biology or therapeutic oligonucleotide development is an asset, but is not required.
