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 ... -
Link Foundation Fellowship Final Report
(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
(2009-06)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; ... -
Countercurrent Flowthrough Pretreatment of Cellulosic Biomass
(2015)The aim of my work as a Link Fellow was to develop an analytical framework incorporating fluid mechanical, thermodynamics and kinetic factors to determine the feasible domains of hot water FT pretreatment. I addressed ... -
High-Resolution, Stochastic Electricity System Models are Key to Driving Low Carbon Policies in India.
(2016)Wind and solar generation sources have the potential to significantly replace fossil fuel-based generation in electricity grids and mitigate anthropogenic climate change. Their rapidly decreasing costs, along with ... -
Design and Synthesis of Low-bandgap Polymers for Organic Photovoltaic Applications
(2015)This research at UCLA focused on the design and synthesis of novel conjugated polymers as the electron-donor material for photovoltaic devices. By careful molecular design both on the polymer backbone and the side chains, ... -
Measuring and modeling the Effects of Energy Efficiency and Renewable Energy on Microgrid Operational Performance and Community Welfare in Haiti
(2014)While central grid extension often provides electricity at very low cost, the reliability of the central grid in less developed countries is so low that the priority given by policy makers to central grid extension must be ... -
Semi conducting Polymer Assisted Separation of Semiconducting Carbon Nanotubes for High Efficiency Hybrid Photovoltaics
(2014)The works reported here demonstrate that we can tune the purity, yield and bandgap of sorted semiconducting carbon nanotube by applying various solvents, polymers, carbon nanotube types and sorting procedure. As a result, ... -
Next-Generation Wind Turbine Blades: Transformative Design of Inboard Cross sections
(2013)Little is known about the aerodynamics of biplane wind turbine blades. Even more fundamentally, the two-dimensional aerodynamics of thick biplane airfoils are not well-understood. Supported by the Link Foundation Energy ... -
Deployment of an Inexpensive, Reliable, and Low Carbon Electric Power System Requires New Modeling Tools.
(2013)The electricity system is of fundamental importance to the decarbonization of the entire energy system, as fuel switching away from oil and natural gas and towards electricity is a key decarbonization statregy. The scenarios ... -
III-Nitride Optoelectronic Devices: From Ultraviolet detectors and visible emitters towards terahertz intersubband devices.
