Evening Optical Spectroscopy Jobs (NOW HIRING)

Department Overview

The Wang Lab in the Department of Biomedical Engineering at Oregon Health & Science University (OHSU) in Portland, Oregon, is recruiting a Research Assistant to support NIH-funded research focused on developing fluorescent small-molecule probes for fluorescence guided surgery and disease early detection. 

We are seeking a motivated scientist who is excited to work at the interface of chemistry, engineering and translational medicine. Applicants should submit a cover letter describing their research interests, and a CV.

Portland is a bike-friendly and scenic city with a vibrant culture around music, coffee, food, and outdoor recreation. The Pacific Ocean, Cascade Mountains, and Columbia River Gorge are all within approximately 90 minutes of the city, providing exceptional opportunities for hiking, skiing, and exploring the Pacific Northwest.

Function/Duties of Position

The Research Assistant will contribute to the full probe development pipeline, including multi-step organic synthesis and purification of novel fluorophore candidates, structural verification and purity assessment by HPLC-MS and NMR, and photophysical characterization through absorption and emission spectroscopy, molar extinction coefficient measurements and quantum yield determination. The position will also support preclinical evaluation of imaging probes in rodent models under approved IACUC protocols, including probe formulation, intravenous administration, terminal surgical dissection, fluorescence imaging and image analysis.

Additional Details

This position is located at OHSU's south waterfront campus (RLSB and KCRB); work hours are 8:00am - 5:00pm with occasional evening and weekend work as needed. Work is performed in a laboratory research environment.

The position involves routine handling of hazardous chemicals, including organic solvents and reagents requiring use in a chemical fume hood, and work with laboratory rodents. Exposure to laboratory animals, rodent bedding and allergens is expected; enrollment in the OHSU Occupational Health program for rodent handlers is required. Personal protective equipment, including lab coat, gloves and safety eyewear, is required. Work involves use of light sources and associated optical imaging equipment; laser and optical radiation safety training will be required if applicable to the equipment in use. The position requires standing at a bench or fume hood for extended periods, fine motor manipulation for chemical and small-animal procedures, and the ability to lift and carry up to 25 pounds (e.g., solvent containers, gas cylinders, etc.). Visual acuity sufficient for reading instrument displays, thin-layer chromatography plates, and fluorescence images is required. Experimental timepoints may require occasional evening or weekend work to complete time-sensitive synthesis or in vivo imaging studies. Work is performed on site; the position is not eligible for remote work.
