LCSR Seminar – Eli Peli: The Risk of Pedestrian Collisions with Peripheral Visual Field Loss @ B17 Hackerman Hall
Feb 8 @ 12:00 pm – 1:00 pm


Patients with peripheral field loss complain of colliding with other pedestrians in open-space environments such as shopping malls. Field expansion devices (e.g., prisms) can create artificial peripheral islands of vision. We investigated the visual angle at which these islands can be most effective for avoiding pedestrian collisions, by modeling the collision risk density as a function of bearing angle of pedestrians relative to the patient. Pedestrians at all possible locations were assumed to be moving in all directions with equal probability within a reasonable range of walking speeds. The risk density was found to be highly anisotropic. It peaked at ≈ 45° eccentricity. Increasing pedestrian speed range shifted the risk to higher eccentricities. The risk density is independent of time to collision. The model results were compared to the binocular residual peripheral island locations of 42 patients with forms of retinitis pigmentosa. The natural residual island prevalence also peaked at about 45° nasally but at about 80° temporally. This asymmetry results in a complementary coverage of the binocular field of view. Field expansion prism devices will be most effective if they can create artificial peripheral islands at about 45° eccentricities. The collision risk and residual island findings raise interesting questions about normal visual development.

LCSR Seminar – Thomas Bewley: Development and coordination of practical balloon swarms for persistent in situ real-time measurement of hurricane development @ B17 Hackerman Hall
Feb 15 @ 12:00 pm – 1:00 pm

This talk proposes a low-cost balloon observation system for sustained (week-long), broadly distributed, in-situ observation of hurricane development. The high-quality, high-density (in both space and time) measurements to be made available by such a system should be instrumental in significantly improving our ability to forecast such extreme and dangerous atmospheric events.  Scientific challenges in this over-arching problem, which is of acute societal relevance, include:

(a) the design and engineering of small, robust, sensor-laden, buoyancy-controlled balloons that don’t accumulate ice, and are deployable from existing NOAA aircraft,
(b) the ultra-low-power operation of the environmental sensors, GPS, logic, and both satellite and balloon-to-balloon communication electronics on the balloons leveraging cellphone and IoT technologies,
(c) the implementation of a self-reconfiguring Mobile Ad hoc Network (MANET) amongst the (mobile) balloons to maintain low-power balloon-to-balloon VHF or UHF communications, typically over 10 to 30km distances, and
(d) the development of hierarchical systems-level control algorithms for autonomously coordinating the motion of the balloons in the swarm to simultaneously achieve, on average, both good coverage and good connectivity while minimizing the control energy used, including the tight integration of
a (centralized) model-predictive control (MPC) strategy for large-scale coordination, incorporating the cutting-edge WRF hurricane data assimilation and forecasting code, and
a novel (decentralized) three-level-control (TLC) strategy for smaller-scale disturbance rejection, designed to correct for the random walk of the balloons due to the unresolved smaller-scale flowfield fluctuations only occasionally, as necessary.


Thomas R Bewley (BS/MS, Caltech, 1989; diploma, von Karman Institute for Fluid Dynamics, 1990; PhD, Stanford, 1998) directs the UCSD Flow Control and Coordinated Robotics Labs, which collaborate closely on interdisciplinary projects.  The Flow Control Lab investigates a range of questions ranging from theoretical to applied, including the development of advanced analysis tools and numerical methods to better understand, optimize, estimate, forecast, and control fluid systems. The Coordinated Robotics Lab investigates the mobility and coordination of small multi-modal robotic vehicles, leveraging dynamic models and feedback control, with prototypes built using cellphone-grade electronics, custom PCBs, and 3D printing; the team has also worked with a number of commercial partners to design and bring successful consumer and educational-focused robotics products to market.

LCSR Seminar – Samuel Kadoury: Optical shape sensing for device tracking in MR-guided interventions @ B17 Hackerman Hall
Feb 22 @ 12:00 pm – 1:00 pm


Image-guided interventional systems rely on accurate device tracking technologies, such as optical or electromagnetic (EM) systems to navigate tools with high resolution diagnostic imaging modalities, such as CT/MRI/PET and facilitate the targeting of specific tissue within the body. However for MR-guided procedures such as Magnetic Resonance Navigation (MRN) which exploits the high magnetic field of an MRI scanner to steer magnetic nanoparticles embedded in drug-eluting beads (DEB), traditional tracking methods are not suitable to visualize catheters inside the patient’s vascular network.  This talk will focus on the development of optical shape sensing devices which overcome the limitations associated with these past approaches with the ability to be integrated into sub-millimeter size tools. We present two MR-compatible solutions, using distributed fiber Bragg gratings (FBG) sensors and ultraviolet curing for optical frequency domain reflectometry (OFDR) measuring strain applied to a fiber triplet inserted in a tool and reconstruct the 3D shape during navigation. Recent phantom and ex-vivo experiments compare the accuracy to EM tracking and demonstrate the insensitivity towards external magnetic fields, illustrating the potential of these approaches for image guidance.


Samuel Kadoury is an associate professor in the Computer and Software Engineering Department at Polytechnique Montreal, member of the Biomedical Engineering Institute at the University of Montreal and researcher at the CHUM Research Center. He currently holds the Canada Research Chair in Medical Imaging and Assisted Interventions at Polytechnique Montreal. He obtained his Masters in Electrical Engineering from McGill University in 2005. After a one-year period at Siemens Corporate Research in Princeton, NJ, he returned to Montreal to complete his Ph.D. in biomedical engineering, focusing on orthopaedic imaging.  He completed a post-doctoral fellowship at Ecole Centrale de Paris and worked as a clinical research scientist for Philips Research North America at the National Institutes of Health in Bethesda, MD from 2010 to 2012, developing image-guided systems for liver and prostate cancer. Prof. Kadoury has published over 100 peer-reviewed papers in leading journals and conferences in fields such as biomedical imaging, computer vision, radiology and neuroimaging. He holds 5 US patents in the field of image-guided interventions, has participated in the technological transfer of multiple research projects to commercial products, and was awarded the NIH merit award for his work on prostate cancer, as well as the Cum Laude Award from the RSNA for his work in artificial intelligence for liver cancer detection.

LCSR Seminar: TBA @ B17 Hackerman Hall
Mar 1 @ 12:00 pm – 1:00 pm
LCSR Seminar: Saeed Abdullah “Circadian Computing: Sensing and Stabilizing Biological Rhythms” @ B17 Hackerman Hall
Mar 8 @ 12:00 pm – 1:00 pm


Rhythms guide our lives. Almost every biological process reflects a roughly 24-hour periodicity known as a circadian rhythm. Living against these body clocks can have severe consequences for physical and mental well-being, with increased risk for cardiovascular disease, cancer, obesity and mental illness. However, circadian disruptions are becoming increasingly widespread in our modern world. As such, there is an urgent need for novel technological solutions to address these issues. In this talk, I will introduce the notion of “Circadian Computing” – technologies that support our innate biological rhythms. Specifically, I will describe a number of my recent projects in this area. First, I will present novel sensing and data-driven methods that can be used to assess sleep and related circadian disruptions. Next, I will explain how we can model and predict alertness, a key circadian process for cognitive performance. Third, I will describe a smartphone based tool for maintaining circadian stability in patients with bipolar disorder. To conclude, I will discuss a vision for how Circadian Computing can radically transform healthcare, including by augmenting performance, enabling preemptive care for mental health patients, and complementing current precision medicine initiatives.



Saeed Abdullah is a Ph.D. candidate in Information Science at Cornell University, advised by Tanzeem Choudhury. Abdullah works on developing novel data-driven technologies to improve health and well-being. His research is inherently interdisciplinary and he has collaborated with psychologists, psychiatrists, and behavioral scientists. His work has introduced assessment and intervention tools across a number of health related domains including sleep, cognitive performance, bipolar disorder, and schizophrenia. Saeed’s research has been recognized through several accolades, including the $100,000 Heritage Open mHealth Challenge winner, a best paper award, and an Agile Research Project award from the Robert Wood Johnson Foundation.
