Research Specialist II

A full-time Research Specialist position is available in the laboratory of Professor James C. Sturm. We are seeking a passionate and goal-oriented Microfluidics Engineer to lead the design, simulation, fabrication, and experimental validation of microfluidic devices for particle-sorting. This role demands a hands-on engineer with a strong foundation in Deterministic Lateral Displacement, CAD design, Multiphysics modeling and microfabrication in a collaborative mindset to drive projects from concept to completion. This role involves leading one or more innovative research projects in particle sorting, with a primary focus on improving throughput and separation efficiency. This is a one year term position. 

Responsibilities include but are not limited to:

• Design and development of our microfluidic device for bioparticle sorting using Deterministic Lateral Displacement technology: perform modeling, simulation, and validation of fluid dynamics in microchannels using tools such as COMSOL Multiphysics or ANSYS Fluent; fabricate particle sorting devices in cleanroom.
• Set up microfluidic imaging system, run particle sorting experiments, analyze fluorescence image data and evaluate performance metrics for high and low Reynolds numbers.

• Optimize device performance: throughput, sorting efficiency; stay up-to-date on emerging trends, materials, and fabrication techniques in MEMS and microfluidics.

Essential Qualifications:

• Bachelors's degree in Materials Science/Engineering, Mechanical Engineering, Electrical Engineering, Physics, or a related field.
• 3+ years of hands-on experience in microfluidics
• Strong knowledge of microfabrication processes: photolithography, spin-coating, DRIE etch processes, chemical wafer cleaning, and other relevant silicon microprocessing and metrology techniques.
• Experience with fluid dynamics modeling tools (e.g., COMSOL, ANSYS) and CAD tools (e.g., AutoCAD, SolidWorks).
• Experience with fluorescence microscopy
• Image processing
• Familiarity with particle sorting theories and experiments
• Excellent problem-solving skills, attention to detail, and the ability to work independently or in multidisciplinary teams.
• Strong written and verbal communication skills, especially around documentation, technical reporting, and presentations.

Preferred Qualifications:

• Experience in diagnostics, lab-on-chip systems, or biomedical applications.
• Familiarity with silicon drilling and dicing
• Familiarity with SEM
• A demonstrated record of research accomplishment in microfluidic particle sorting
