I am an Urban Science Faculty Fellow at the Center for Urban Science and Progress at New York University. I recently completed a PostDoc and PhD in Geographic Information Science at the Spatial Analysis Research Center (ASU) with a focus on computational methods and local regression models to analyze urban processes with applications in crime, housing markets and urban health outcomes amongst others. I have prior experience as a geospatial data scientist at Carto (a SaaS web-mapping platform) and have a graduate degree in urban planning and analytics from Columbia University and an undergraduate degree and professional background in architecture. As a passionate researcher and an urban enthusiast, everything I have engaged in so far has been driven by a keen interest in the coexistence of urbanity and ecology and the impact of human footprint on the environment. In my spare time I run, hike, paint and read.

Multiscale Spatially Varying Poisson Model
A recent addition to the local statistical modeling framework is the implementation of the Multiscale Geographically Weighted Regression (MGWR) model, a multiscale extension to the widely used approach for modeling process spatial heterogeneity, Geographically Weighted Regression (GWR).

Local Modeling Perspectives on Scale Issues
The concept of ‘spatial scale’, or simply ‘scale’ is implicit in any discussion of global versus local models. The raison d’etre of local models is that a global scale (where here ‘global’ simply refers to all locations within a predefined area of interest) might be the incorrect scale at which to undertake any analysis of spatial processes; the alternative being a local scale (where here ‘local’ refers to individual locations).

Diagnostics for appropriate model form
Studies of spatially varying parameter estimates obtained in the calibration of various types of local statistical models are commonplace. The variation in such estimates is typically explained in terms of spatially varying processes.

Local House Price Modeling
Real estate market analysis has long been an active area of inquiry and one that reveals much about people’s preferences regarding housing attributes. It is well-known that house prices tend to exhibit strong spatial dependency and that they vary across space due to differences in structural and neighborhood characteristics.

City Studio - Advances toward the “20-Minute City” vision for Tempe
City Studio is an Arizona State University (ASU) course developed to allow ASU and the City of Tempe to collaborate on Tempe’s 20-Minute City project. ASU worked with Tempe staff to develop the City Studio class.

CARTO - Research and Development
Space-time Autocorrelation using NYC taxi data (2015) This project explores spatial and temporal autocorrelation. Open-source yellow taxi trip data for the year 2015 was aggregated to a 50m * 50m grid across NYC.
CARTO - Research and Development
CARTO - Workshops and Contributions
My first contribution to the CARTO environment was to develop materials for the Carto Academy depicting how to implement and interpret spatial tools on the web GIS platform. This has since been deprecated to accommodate for changes in the version of the current software.

Resilient Island Culture Studio, Staten Island
The Resilient Island Culture Studio was tasked to address housing and resiliency issues on Staten Island in the aftermath of Hurricane Sandy. With Make the Road New York as the studio client, emphasis was placed on serving lower-income communities that have not fully recovered from the storm.

Efficiency and Accessibility of NYC and Chicago Subway networks
As wealth gaps increase in American Cities certain lower income populations in cities will grow more vulnerable if their transportation needs are not met. We can use GIS to spatially research where the highly dense areas are that may be currently underserved by existing Subway infrastructure in cities.

Environmental justice study - New York City and Chicago
Concerned with environmental injustice and the many ill-impacts it has on the residents of affected neighborhoods, I realized through existing literature that there were sources of toxic air pollutants existing within close proximity to our daily land-uses.

Reclamation Institute for Social Ecology
In 2013, deeply concerned about rampant mining in some parts of India and their subsequent abandoning I came across some abandoned asbestos mines, south of the city of Udaipur that had left a toxic trail for the community dwellers to deal with.

Resurgence of the City Center
In this urban theory studio during my undergraduate studies in architecture, the aim was to study and implement a plan for the resurgence of the center of the city of Vadodara, India, long known for its Colonial architectural style.
