PROJECTS

New York City: Booms and Blooms

New York City neighborhoods bloomed through five construction booms. How did each neighborhood develop, and what is the new trend in NYC construction?

Nacre characterization

How are seashells so strong? This research reveals a new strengthening mechanism of seashells.

Google Decimeter Challenge: Advanced Kalman Filter

Can we enhance the accuracy of the GPS on our phones? Maybe down to a decimeter accuracy?

A geographic approach to housing price prediction

The neighborhood is an important factor when you look for a house. How can we evaluate the geographic value?

COVID through the Lens of Vulnerable Youth

Was NYC prepared for this unprecedented social disaster?

Competition and Monopoly in the US Airline Industry

Airline sector is a competitive industry. A pricing model is tested through multiple linear regression with three parameters: customers, routes, and hubs.

3D Concrete Printing

3DCP is an emerging technology that offers the potential to transform the construction industry and contribute to the sustainability of the industry.

Cement Hydration Monitoring

Despite its ubiquity, we still do not fully understand how concrete sets and gains its strength. This real-time visualization of the setting process gives us new insights.
