These are some of the things that keep me busy when I am not traveling.
Understanding and modeling complex systems such as cities, transport systems, social systems, and financial systems, is part of my job description.
My work exposes me to various datasets, both big and small. My main DS language is Python, but I also speak R. I am a huge fan of Tableau, QGIS, & Gephi.
Stock trading is a hobby I picked up back in 2008. Between a TA and a "fundamentalist," I am more the former. I enjoy watching price & volume movements.

Sharing some news on us and the research that we do.

The Asian Institute of Management bets on data science as one way to reclaim its place among the top business schools in Asia

“Harvesting data is a data scientist’s core competency, but also equally important are the abilities to model, visualize, and turn data into actionable insights, and to pose the right questions that matter to the business,” Legara added.

A*STAR researchers have developed a machine-learning program
to accurately recreate and predict public transport use, or 'ridership', based on the
distribution of land-use and amenities in Singapore.
18 December 2014
Researchers have developed a computer model
that analyzes networks of interconnected roads to predict the speediest routes for
rescuers to take using real-time data uploaded by aid workers on the ground.
21 November 2014
The introduction of smartcard ticketing for SG's public transport system has
enabled researchers to provide valuable predictive data on potential train overloading.
This will enable system planners to address critical bottlenecks as the system stretches
to accommodate an expanding population.
Featuring some posts from my blog @ erikafille.ph.
Complexity is a very open and engaging field. I am quite hopeful that in the near future, scientists and social scientists of our nation would collaborate and reduce the gap between the "hard" and "soft" sciences, pushing for more grounded and well thought out policies, taking advantage of what we know about Complexity
"In this article, Dr. Monterola and Dr. Legara explain why cities like Singapore should be understood
as complex systems, and how we can better understand cities through agent-based modeling (ABM)."

We found that MLM membership growths decelerates after reaching a size threshold, contrary to claims of unbridled growth. The network does not grow continuously nor exponentially, but slumps down after some threshold level. This resulting growth dynamics was also observed in the data collected from an actual MLM company.
