A site about my work.

A place to share my passion for science and for education.

This site is about my work as a researcher, an educator, and a member of an international professional community. It is also a place where I share my passion for science and for education, as well as the excitement I feel when I hear about new advances and discoveries in STEM (Science, Technology, Engineering, and Mathematics) fields. The blog posts include links to external news articles describing recent research that I find particularly amazing. This collection is neither exhaustive, nor meant to represent all of the excellent work done by mathematicians, scientists, and engineers worldwide. But I hope you will find these stories as exciting and motivating as I do.

Modeling Through Challenge

Reproduced from the Fall 2015 School of Mathematical Sciences newsletter (PDF) Download a PDF copy of this article Chikungunya fever in the Americas In August 2014, DARPA (the federal Defense Advanced Research Projects Agency) launched a challenge, asking the public to predict the number of cases of chikungunya fever in each of the PAHO (Pan American Health Organization) countries, many of…

On the Importance of Mathematical Models

Last month, our team won the DARPA Chikungunya Challenge. We were asked to predict the number of cases of Chikungunya observed in the Pan American Health Organization (PAHO) countries from the beginning of September 2014 till the end of February 2015. Our predictions were then scored against the actual numbers reported on the PAHO website. Points were also awarded for methodology, presentation,…

Satellite Imaging

Take a look at these recent images from two satellite missions. A fluorescence map of the world from the OCO-2 (Orbiting Carbon Observatory 2) satellite, indicating regions of high photosynthesis activity. A video showing ice loss of the Greenland ice sheet, from data collected by ICESat (Ice, Cloud and Elevation Satellite).

How Cells Move in a Multicellular Organism

Answering the question of how cells move in a multicellular organism is interesting in itself but may also lead to important applications, such as a better understanding of how metastatic cancer actually spreads. Researchers at NIH, Rochester, and Penn State, have identified a new way for cells to move inside a three-dimensional matrix: by using the cell nucleus as a piston! The…
