Learning Meaningful Representations of Surgical Motion Without Annotations
(2019)Superior technical skill in the operating room is associated with better patient outcomes [3,18], and at the core of surgical education is the belief that technical skill is improved through deliberate practice and appropriate ... -
Auditory and Vestibular Control of Inverted Pendulum Dynamics in Spatial Orientation
(2019)Human standing balance requires continuously nulling the tendency to fall like an inverted pendulum, and this process relies on the convergence of information from multiple sensory modalities including vestibular, vision, ... -
A vision-based model of crowd navigation
(2019)Humans navigate crowds daily. This can range from quick interactions between pedestrians on the sidewalk to jostling through a busy train station. Research in fields diverse as computer graphics, physics, evacuation planning, ... -
Using immersive virtual reality to assess context-dependency of locomotor skill learning in people with Parkinson's disease
(2019)Parkinson’s disease (PD) is a progressive neurodegenerative disorder resulting from a loss of multisystem degenerations and neurotransmitter deficiencies such as dopaminergic and cholinergic degenerations [1]–[4]. The ... -
Improving the ability to study coastal nutrient dynamics through the development of high-resolution water samplers
(2018)Globally, marine ecosystems are experiencing fundamental shifts in their structure and function. Due to the high level of interconnectedness between aquatic organisms and their environment, they are highly sensitive to ... -
Optimal Configuration and Tuning of Wave Energy Converter Arrays
(2016)Power from ocean waves is becoming an increasingly attractive option as a source of renewable energy. Ocean waves are more reliable and predictable than sun and wind, and have a higher energy density [1]. There are locations ... -
Nonlinear Ocean Energy Harvester
(2018)The scientific community has worked to extend communication networks, human safety programs, and environmental monitoring systems across continents, but has struggled to accomplish these same goals beyond the shoreline. ... -
Extraction of Phase-Resolved Wave Data from X-Band Radar Imagery
(2018)Typically, phase-resolved measurements of the sea surface are limited to single-point time series from in situ sensors, or arrays of multiple in situ sensors. The deployment of such devices is costly and time intensive, ... -
Link Foundation 2008‐2010 Energy Fellowship Report
(2010)I completed my PhD in Engineering and Public Policy at Carnegie Mellon University in May of 2010. My dissertation, entitled Developing Useful Long-term Energy Projections in the Face of Climate Change, seeks to identify ... -
Link Foundation Fellowship Report
(2008-09)Peak hour electricity demand is associated with wholesale electricity prices that are sometimes more than 10 times higher than in off-peak periods. During these high-demand periods congested transmission lines and insufficient ... -
Polyelectrolyte Materials for Dielectric Elastomer Energy Harvesting
(2017)Dielectric elastomers actuators are compliant capacitors which can convert electrical energy into mechanical energy [1]. The simplest device consists of a thin elastomer sheet sandwiched between two compliant electrodes. ... -
Summary of work while a Link Energy Fellow
(2010)Electrons have an intrinsic property called spin, which is found in one of two states, an “up” and a “down”. The spin state of an electron can be observed and differentiated by applying an external magnetic field and ... -
Final Report for the Link energy Fellowship
(2009)A sustainable energy future is critical for environmental and strategic reasons. Fossil fuel use has increased greenhouse gas emissions, and continued consumption could adversely change global climate. In addition, the ... -
Evaluating the Potential of Ubiquitous Flexible Energy Loads to Provide Grid-Scale Balancing in Resource Constrained Environments: A Case Study in Nicaragua
(2018)Future growth in urbanization will mainly occur in cities of the rising south. UN Habitat reports that in the past decade, the urban population in emerging economies grew on average 1.2 million people per week. By 2050, ... -
Solar Energy Storage Using Earth-Abundant Materials
(2017)Among alternative energy technologies, solar is well suited to meet the grand energy challenge ahead if we can overcome the intermittent supply of sunlight.1,2 Storing solar energy in chemical bonds serves as an attractive ... -
Development and non-toxic and stable perovskites for high efficiency solar cells
(2017-09)The efficiency of halide perovskite solar cells has dramatically increased from 9% to 22% in less than 5 years.1 They have shown promise toward the future for low cost and highly efficient solar electricity. While there ... -
Skin Deformation Feedback for Force Sensory Substitution in Teleoperation and Virtual Reality Training
(2017-08-28)For this work, we developed a wearable skin deformation device that is worn on the tip of the finger. The devices have two separate components, the first of which is a finger grounding interface that straps to the medial ... -
Physical-Virtual Patient Bed
(2017-08-28)Currently healthcare practitioners use patient simulators such as actors, mannequins, and computer based simulations for learning and training.I am exploring effects of co-locating sensory cues (i.e. visual and haptic) vs ... -
Mobile in-situ visualization
(2017-09-01)In this work we present a new distributed technique to geometrically calibrate multiple projectors on a fiducial free arbitrary surface using multiple casually aligned cameras where every point of the surface is seen by ... -
Environmental Implications of Consumer Preferences and Policy Incentives for Plug-in Vehicles in China and the U.S.
(2016)China’s State Council has linked this vision to its economic development plans, which emphasize industrial upgrading to higher technologies and higher value added roles in global production chains (Howell et al., 2014; ...
