The Functional Optical Imaging Lab (FOIL) at Northwestern University is dedicated to develop novel optical, ultrasonic, and electrical imaging techniques for biomedical research and clinical applications.
The research work in FOIL is highly interdisciplinary. It involves knowledge and expertise from electronics, optics, lasers, ultrasound, imaging processing, programming, mechanics, physiology, anatomy, and clinical science. Hence, FOIL is setting up collaborations in a wide spectrum nationwide.
Where we are
We are located in Tech Institute EB11/EB13/EB15/EB17/EB57/EB59.
Postdocs: We have two post-doct position open. Please find more details here.
Ph.D. student: We usually admit 1 or 2 new Ph.D. students every year. The application to Northwestern BME is very competitive and only less than 10% of the applicants will receive offers. However, completing your Ph.D. study at Northwestern University is very rewarding from all aspects. If you are interested in our lab, please contact H. F. Zhang. More informaiton regarding the application procedure can be found from the BME website.
Undergraduate student: We are looking for undergraduate student to work on imge processing of super-resoltuion optical microscopy and metabolic retinal imaging. If you are a Northwestern University student interested in undergraduate research, or student from other schools interested in summer research, please contact H. F. Zhang directly.
Visiting scholar: FOIL welcomes visiting scholars to conduct jointly interested projects. Please contact H. F. Zhang for more information.
