I
am an assistant professor in the departments of Ophthalmology and
Biomedical
Engineering (secondary appointment) and a faculty member of Fitzpatrick
Institute for Photonics. Before this, I was a postdoctoral
member
of the Duke Advanced
Research in SDOCT Imaging (DARSI) Laboratory at the
Ophthalmology
Department, and the Laboratory for
Biophotonics
at the BioMedical Engineering Department (supported in part by a North Carolina Biotechnology Center
grant). I spent six years in the beautiful
For
some strange reasons my research interest is in information processing.
More
specifically, my main areas of research are ophthalmic imaging and
image
processing, segmentation, super-resolution,
demosaicing/deblurring/denoising,
motion estimation, adaptive sampling, sensor fusion, photonic imaging
through
scattering media, optical coherence tomography (OCT), and X-ray
imaging.
At
the ophthalmology department, I am the director of the Vision and Image
Processing (VIP) Laboratory.
Along with my colleagues,
we investigate
how to improve early diagnostic methods, and find new imaging
biomarkers for
both age-related macular degeneration (AMD) and for retinal diseases in
children. On another front, we study efficient signal processing based
methods
to overcome the theoretical and practical limitations that constrain
the
achievable resolution of any imaging device. Our approach which is
based on
adaptive extraction and robust fusion of relevant information from the
expensive and sophisticated as well as simple and cheap sensors, has
found wide
applications in improving the quality of imaging systems such as
ophthalmic
SDOCT, digital X-ray mammography, electronic and optical microscopes,
and
commercial digital camcorders. When
I'm not busy developing a mathematical model of the procrastination
theory, I'm a reviewer for IEEE

There are
openings for postdocs and
exceptional graduate/undergraduate students (BME, EE, CE,
or CS). POSTDOCTORAL Research Associate Position (Updated 10/10/2009, available immediately): Funding available for two years, with the initial appointment for one year with the possibility of a multi-year extension pending the work progress. Successful candidates will collaborate with me and senior professors in the departments of Ophthalmology, Duke Reading Center, and BME on a project mainly focused on detection and segmentation of pathological features in ophthalmic specatral domain optical coherence tomography (SD-OCT) images. No previous experience in ophthalmic sciences is necessary. The postdoc applicant must have peer-reviewed publications in the high impact computer vision and/or image processing journals (TIP, PAMI, TMI, OE, etc). Aside from the theoretical work, these projects involve software development and the applicant must be fluent in at least one programming language. If interested, the postdoc will collaborate and learn about desiging photonics imaging systems. If interested please send me your CV via email in the PDF format. Undergraduate/Graduate
Student: Duke
students interested in image processing/ophthalmology related projects
can
contact me directly via email or drop by my office. Graduate
Student (filled):Thanks
to a Knights Templar Eye Foundation, Inc. Pediatric Ophthalmology Research Grant there
is funding available for (currently) one year support of a graduate
student to work on an ophthalmic image fusion and enhancement
problem.
Current Duke students of all disciplines who have
background in image processing and are
fluent in at
least one
programming
language are encouraged to contact me directly. Support for more than
one year is possible but not guaranteed. Duke's 3rd Year Medical Students: Medical students interested in participating in ophthalmic imaging research projects related projects may contact me directly. Please call or send me an email with your detailed CV. POSTDOCTORAL Research Associate Positions (ongoing search): Postdoctoal positions are occasionally available. Successful candidates will collaborate with me and senior professors in the departments of BME and Ophthalmology on projects that are mainly focused on detection and segmentation of pathological features in ophthalmic images and/or adaptive ophthalmic imaging and image reconstruction. No previous experience in ophthalmic sciences is necessary. The postdoc applicant must have peer-reviewed publications in the high impact computer vision and/or image processing journals (TIP, PAMI, TMI, etc). Aside from the theoretical work, these projects involve software development and the applicant must be fluent in at least one programming language. If interested please send me your CV via email, and I will inform you when an appropriate position becomes availble.
* Please send me links to files instead of attachments (especially if they are in any format but PDF), since I usually ignore emails with attachments. Also, please do not send me emails in any language but English or Gathic Avestan. *If
you don't receive an
email reply in 7 days: My apologies, it might be deleted by the SPAM
filter. Feel free to call me instead. *Here is a picture of me from the good old days in
Santa Cruz, and
