hello,I am Erika.

I Data

I am a scientist with a Ph.D. in Physics interested in complex systems and data-driven science.

I enjoy looking for patterns in datasets and building theories and models—from mathematical modeling, to machine learning (and deep learning), to cellular automata and agent-based modeling.

In July 2017, I joined the Asian Institute of Management as associate professor, and also, as program director of the first data science graduate program in the Philippines. Before joining AIM, I was a scientist at IHPC, A*STAR, Singapore from 2012-2017.

Work & Play

These are some of the things that keep me busy when I am not traveling.

Complexity Science

Understanding and modeling complex systems such as cities, transport systems, social systems, and financial systems, is part of my job description.

Data Science

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

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.

Helping trains take the strain

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.

Complexity and the Philippine Society

June 2012

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

ABM of Urban Complexity

October 2016

"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)."
- Assoc. Prof Cheong Siew Ann

Thinking through pyramid-like business schemes

February 2013

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.
