Excellent written and oral communication skills, ability to document work clearly and present results. Ability and enthusiasm to work in multi-disciplinary, inclusive, and collaborative environments. Project Specific Knowledge and Abilities Familiarity with nucleoside / nucleobase chemistry or nucleic acid analogues (or willingness to learn quickly). Understanding (or ability and desire to develop understanding) of photophysical and fluorescent probe behavior in biologically relevant media. Ability to work with biophysical / biochemical collaborators (e.g. for evaluating probe behavior). Sensitivity to the demands of designing minimally perturbing molecular probes that integrate with nucleic acid frameworks. Minimum Education & Experience A doctoral degree in an appropriate field 0-5 years of relevant experience Preferred Qualifications & Special Skills PhD. in organic chemistry, chemical biology, or a related discipline, to be completed before appointment. Demonstrated record of creativity and research productivity (e.g. publications, presentations, successful projects during Ph.D.). Experience performing multi-step syntheses, purification, and structural verification. Prior experience in nucleic acid chemistry (e.g. oligonucleotide synthesis, nucleobase analogues, nucleoside modification). Experience working with photophysical, spectroscopic, or biophysical assays (fluorescence spectroscopy, binding assays, etc.). Experience mentoring or training more junior students or staff. Demonstrated ability to contribute to collaborative projects and to interface with external partners or industry collaborators. An awareness of challenges in probe design (e.g. steric perturbation, fluorescence quenching) and prior examples in literature.
