About Us

Voxeleron LLC was co-founded in 2010 by Daniel Russakoff and Jonathan Oakley.  With a wealth of experience in the field of computer vision and software development, our researchers can add significant expertise to your company. Contact us today to find out more and how Voxeleron LLC can contribute to your organization.


Jonathan Oakley has a B.Sc. in Computer Science from the University of York, England, a Masters from University College, London, and a Ph.D. in medical image processing from the Swiss Federal Institute of Technology.  Since then, he has spent more than a decade working on image processing algorithm development for KLA-Tencor, Fujifilm and Carl Zeiss Meditec Inc. His research interests are primarily in medical image processing, with a clear emphasis on ophthalmic applications.

Daniel Russakoff received an A.B. in Geophysics from Harvard University and his Ph.D. in Computer Science from Stanford. His research interests are in computer vision and pattern recognition in general, and biomedical image analysis in particular. He has authored numerous conference and journal papers and holds several patents on topics ranging from stereo vision to medical image registration. He has worked as a Computer Scientist at the National Institute of Standards and Technology and as Chief Scientist at Fujifilm’s San Jose Research Lab. His more recent work has been using probabilistic shape analysis and machine learning for segmentation of deformable structures in 2D and 3D radiological images.


Principal Scientist

Prior to joining Voxeleron, Christoph Guetter worked as a Research Scientist, Technical Lead, and Project Manager for computer vision research & development at the research lab of Siemens Corporate Technology in Princeton, USA, where he led a group of research scientists and software developers in developing award-winning imaging technology, and brought this technology to the clinical market.

Christoph received his M.Sc. in Computer Engineering from University of Mannheim, Germany, and his PhD in Computer Science from University of Erlangen-Nürnberg, Germany. Christoph has over 30 publications in conferences, journals, and book contributions, and holds more than 20 patents and pending patent applications related to advanced computer vision and image processing systems. His research interests are in computer vision and biomedical image analysis in particular.

Scientific Advisory Board

In addition to delivering state of the art custom software and solutions, Voxeleron is committed to its own program of research and development. Towards that end, Voxeleron’s Scientific Advisory Board was created to offer expertise and help guide the research to address the most interesting and relevant problems. PeterCalabresiDr. Peter Calabresi serves as the Director of the Multiple Sclerosis Center, focusing on the diagnosis and management of Multiple Sclerosis (MS). He is the principal investigator on several clinical trials and oversees research projects seeking to create new anti-inflammatory and neuroprotective therapies for MS. Professor Calabresi has pioneered the use of optical coherence tomography (OCT) in MS identifying the relevance of retinal layers for both the screening and monitoring of this neurological disorder.


BJLPicSmall Dr. Brandon Lujan is a medical retina specialist at West Coast Retina in San Francisco, as well as a clinician scientist at the University of California, Berkeley. Dr. Lujan has been working with advanced OCT systems since completing his fellowship in medical retina and imaging at the Bascom Palmer Eye Institute in 2008.  He is a co-inventor of Directional OCT.  Since the beginning of his training, he has been passionate about providing clinicians the insights they need for interpretation of OCT images so that they can deliver optimal patient care.

These are a voluntary roles and neither Prof. Calabresi or Dr. Lujan have financial interests in Voxeleron LLC.
