about

I have recently finished my PhD in Electrical Engineering (MS in MS&E) at Stanford, advised by Profs. James Sweeney in Management Science & Engineering and Ram Rajagopal in Civil & Environmental Engineering. I graduated with a MSc in Space Physics and BSc degrees in Physics and in Computational Science from Jacobs University Bremen, Germany. My advisor there was Prof. Joachim Vogt.

Statistical modeling of consumption decisions. In their daily interaction with systems such as the energy grid, people make decisions to consume that depend on many factors - preferences, lifestyle, external influences, etc. The system operator (e.g., the energy utility) cannot observe the decisions directly, but it can observe the (noisy) consequences of these decisions in form of the data that people generate - e.g., sensor-recorded data of consumption over time. To be able to affect demand at the individual level - through either targeted marketing or automatic control - companies must infer back the decisions from the data. This ability raises some important privacy questions however, which we also explore from a predictive marketing perspective. Papers: IEEE Big Data'13, ECML'13, IEEE TPS (2013).
Designing portfolios for demand-side management interventions. Variability is of great importance on the energy grid, affecting grid stability, financial operations, and environmental footprint. While predicting individual consumption patterns is hard, it is relatively easy to forecast the aggregate consumption of groups of users. This line of research connects consumption variability of individuals and groups to the costs they impose on the overall system. We learn patterns in consumption variability for individual users, as well as patterns of correlation among consumers, which can be used for targeting, segmentation, and a number of other demand-side portfolio analysis applications. Papers: Journal, ACM Sensys '11,
Optimization and operational control for energy and resources systems. Addressing the estimation problem (obtaining useful statistical characterizations of patterns in demand and supply) is crucial, but not enough by itself. Here we use demand patterns to inform strategies on the supply side (by the system operator) to influence consumption of large individuals (or segments thereof) as to achieve "good behaviors" in the aggregate.

Capoeira

Adrian Albert Adrian Albert

(since 2009) I am a member of the Capoeira Narahari family, training with Mestre Beicola. I started training with Mestre Lagosta of Capoeira Mandinga in Berkeley. Of late I also train with UCA in Berkeley.

Muay Thai

(since 2012) Muay Thai emphasizes upper-body contact and blocks, and so it is a natural complement to Capoeira, which focuses on avoiding contact and on lower-body kicks and acrobatics.

past projects

MSc and BSc theses

Multi-point data analysis for magnetospheric multi-spacecraft missions (MSc Thesis)

For my MSc Thesis research with Prof. Joachim Vogt at Jacobs University Bremen I developed a novel method for processing time series of three-point magnetospheric satellite data. Part of this work has been published (another part sadly never made it to the editor…) slides

Efficient calculations of cosmic particle fluxes in paleomagnetospheres (BSc Thesis)

My BSc thesis with Prof. Joachim Vogt investigated a computationally-efficient method for calculating charged particle fluxes in magnetic fields by considering trajectories of particle populations that were relevant to final flux integration.

Selected internship research projects

Inferring high level personal mobility choices from sparse gps data

In summer 2010 I worked at IBM Almaden Research Center on developing an integrated system that uses GPS information provided by smartphones to analyze and model individuals’ mobility choices. The system collects GPS data from Android and iPhone devices via native apps, sends it automatically to a server, performs analytics, and lets the user view and interact with the results in a web portal. We were interested in extracting high-level travel patterns and dominant choices that could be used as input for a map model-aware route prediction tool.

Lighting authoring effort analysis

We analyzed the authoring effort for several Pixar movies (Ratatouille, Wall-E, and UP) for lighting versus animation effects. Insights of the statistics were used to support research decisions in front of Pixar management (results and written materials are confidential).

At NASA MSFC I worked in the atmospheric and lightning physics group on developing a software package for analyzing electric field change data from an array of sensors in the Huntsville, AL area. poster

Numerical investigation of the kelvin-helmholtz instability

As a summer REU project at the University of California, Santa Barbara, we proposed a novel regularizing scheme for the Birkhoff-Rott equation of an ideal vortex sheet, based on an exponential smoothing term, and performed numerical experiments of the sheet's stability. slides

Visualizing the U.S. freight network

This is a small dashboard I put together for Jeff Heer's visualization class. It describes inter- and intra-state flows of freight and some of its determining factors. Note that for some browsers the zoom setting might need to be adjusted.
