Amit Ashok, Associate Professor (OSC & ECE) and Director, Intelligent Imaging and Sensing Lab (I2SL)
I received my Ph.D. degree in Electrical and Computer Engineering from the University of Arizona (2008) and a Master’s degree in Electrical Engineering from the University of Cape Town, South Africa (2001). Before returning to the University of Arizona, I worked as a Senior Scientist in the research and development division of OmniVision CDM Optics on novel computational imager designs for commercial applications such as security, automotive, cell-phone based imaging. My research interests span the areas of task-based computational imaging and sensing, inverse problems, statistical inference, information theory, and system optimization as it relates to image science. I am also interested in design and analysis of adaptive measurements for task-based imaging and sensing that incorporate active statistical learning techniques. I have made several key contributions in the areas of task-based joint system design framework for computational imaging and information-theoretic system performance measures across several imaging modalities spanning RF to visible/IR and X-ray domains. I have over 50 peer-reviewed publications, holds several US and international patents, and has been invited to speak at OSA, IEEE, SIAM, SPIE and Gordon research conferences. I currently serves as a topical editor for OSA’s JOSA A journal and a general chair of SPIE’s Computational Imaging and Anomaly Detection and Imaging with X-ray conferences.

Tammie Brown, Coordinator, Research Projects (OSC)
I received my Bachelor of Science degree from Temple University in Philadelphia, Pennsylvania and completed graduate course work towards my Masters of Public Administration degree at Long Island University in Brookville, New York. I have worked in the private sector, local government, nonprofit industry, and academia. I have work as program manager, grant writer, assistant director of financial aid, assistant director of grants, and deputy director of grants management to name only a few. I have also assisted with a gubernatorial campaign; have a successful floral design, gift basket, and event coordinating business; have a book club; and regularly volunteer in the audio visual ministry at my church. I love period pieces, documentaries, a good book, cooking, spending time with my family and friends, and laughter – lots of laughter.
Anna Marie Garcia, Administrative Associate (OSC)
I have 30+ years’ experience in the area of financial and office management. As Office Administrator for the Church of the Painted Hills, I was responsible for the financial and administrative functions of running a private organization. While employed with Hearit-Speech Banana Therapy Company, I held the position of Office Manager/Bookkeeper, as well as Manager for Shipping and Receiving. Administrative experience gained at Raytheon/Hughes Aircraft strengthened my skills in managing a large engineering group of 25 employees. Here, I maintained project and employee records, coordinated travel arrangements and events. At OSC, I participate in the rotation of the Colloquium Lecture Series, coordinate special events/workshops, cross-train with the Admin Team and provide administrative assistance to academic faculty and their research teams supporting activity in academia, research, and service.
Yijun Ding, Ph.D., Postdoctoral Research Associate I (OSC)
I was born and raised in China and have been interested in math and physics since I was a kid. I earned my bachelor’s degree in Physics from the University of Science and Technology of China in 2009 and my doctorate with a focus on image science from the University of Arizona. I worked at the University of Colorado cancer center for a year to enrich my knowledge in biology. In 2018, I moved back to Arizona with the goal of improving my skills in math and physics. My current focus is statistics in imaging systems.
Ahmad Masoudi, Ph.D., Postdoctoral Research Associate I (OSC)
I was born and raised in Esfahan, Iran. I received my Bachelor of Science degree in Electrical and Computer Engineering from Isfahan University of Technology in my hometown. In 2012, I moved to New York to pursue a Master of Science degree in Electrical Engineering at NYU. In my master’s studies, I worked on the Positron Emission Tomography (PET) image reconstruction problem. I received my Ph.D. from the University of Arizona with an emphasis in Information theoretical and statistical analysis of X-ray Computed Tomography.
Joseph Cox (Ph.D. program in Optical Sciences)
I earned a BS in Electrical Engineering from New Mexico Tech in 2016. Prior to attending the University of Arizona, I worked at the Naval Air Weapons Center, Weapons Division, and completed work in Radar Imaging and Electronic Warfare. Some of my other areas of experience also includes tracking applications at the Air Force Research Laboratory and electronics and physics simulations at Sandia National Laboratories.
Kwan Kit Lee (Ph.D. program in Optical Sciences)
I received my bachelor’s degree in Physics from The Chinese University of Hong Kong in 2015. I also received a Master of Philosophy degree in Physics from the same university. I focused on the theoretical study of TE-TM splitting in quantum cavities and the topological properties of optical polariton when studying in Hong Kong. I began my Ph.D. in Optical Science at The University of Arizona in 2018. I am now working with Professor Amit Ashok on the topics of application of information theory in imaging and quantum sensing. My areas of interest are theoretical and numerical study of information theory and quantum information and application of statistical techniques in imaging problem.
Jay Voris (Ph.D. program in Optical Sciences)
I was born and raised in Rochester, NY before moving to Baltimore at the age of eleven. I found my interest in mathematics at a local homeschool math club, an interest that continued through many math competitions in high school. I graduated from high school in 2007 and returned to Rochester to study Optics at the University of Rochester. I earned my bachelor’s in Optical Engineering in 2011 and took an extra year on scholarship to study linguistics and Chinese through their Take 5 program. In 2012, I enrolled in the graduate program at University of Arizona to continue my studies in Optical Sciences where I earned my master’s and am finishing my doctorate on Computational Microscopy and X-ray Material Discrimination. My areas of interest are computational microscopy, interferometry, and x-ray tomography.
Hwang-Jye Yang (Ph.D. program in Optical Sciences)
I was born and raised in Taiwan. I earned my bachelor’s degree in chemistry from the National Taiwan Normal University (NTNU) in 2008 and received my master’s degree in physics from the National Taiwan Normal University in 2010. I focused on the Raman spectrum and atomic force microscopy (AFM) during my master’s studies. Between 2012 and 2013, I worked at the National Synchrotron Radiation Research Center (NSRRC) to research gas phase spectroscopy and coherence anti-Stokes Raman scattering (CARS) microscopy. In 2014, I enrolled in the graduate program at University of Arizona and studied optical properties of semiconductor saturable absorber mirror (SESAM) until 2016. Right now, I am focusing on computational optics and imaging process which is applied to the cryptographic-authentication based on the physical unclonable function (UCF). My interests are taking a picture with E.T and taking him home.
