We are seeking highly motivated and creative applicants with a strong background in biomedical optical modeling and a doctoral degree in physics, biomedical or electrical engineering, computer science or related fields. Candidates should have hands-on experience in scientific programming, parallel GPU computing (CUDA platform or similar) and Monte Carlo simulations. Prior work with optical system design (Zemax, CODE V, etc.) and computer-aided design (SolidWorks, AutoCAD, etc.) software is highly desired. Candidates with good interpersonal and writing skills are strongly encouraged to apply. Interested candidates should send a cover letter, CV, and contact information of three professional references (name, address, phone, and e-mail) to position-modeling@cabip-harvard.org.
