I am a spatial data scientist, with research cutting across geographic information retrieval, machine learning, geovisualization, and visual analytics. My research primarily focuses on method development, spanning various domains including social media analytics, sea ice mapping, crisis management, situational awareness, precision agriculture, and digital humanities. A large portion of my research has focused on incorporating spatiotemporal relationships in machine learning and visual analytics. While computational, my approach is human-centered, from visual/system design to algorithm integration and evaluation, to domain deployment and field studies. My visualization-related work focuses on visual analytics for human-in-the-loop machine learning aiming to (1) develop flexible, performant computational methods leveraging human expertise, and (2) helping users understand machine learning methods output/biases when applied to geospatial data.

GEOG 3023 - Statistics for Geography
Primary Instructor
-
Fall 2019 / Spring 2020 / Spring 2021 / Spring 2023 / Fall 2023
Introduces computational and statistical tools to solve problems in the geographic domain. Provides an understanding of introductory statistical concepts and applies them to real world problems through lab exercises. Emphasizes spatial data, which requires specialized descriptive and predictive analysis techniques. Demonstrates how to manipulate and visualize data, and make inference using state-of-the art statistics software, applied to various social and earth science problems. Same as GEOL 3023.
