- 02/05/2020: My first first-author paper with my advisor Mohamed Sarwat, “GeoSpark: a cluster computing framework for processing large-scale spatial data”, was published in ACM SIGSPATIAL 2015 (one of the most prestigious conferences in spatial data management). Now it is the most cited paper among all 633 papers from 2014 - 2019, and the 7th most cited paper among all 935 papers from 2011 to 2019 in this conference, according to Microsoft Academic.
- 12/05/2019: Our project GeoSpark is featured by Databricks (the company behind Apache Spark) in its article “Processing Geospatial Data at Scale”. Databricks provides a GeoSpark notebook for Databricks Spark runtime and Delta Lake. If you have a Databricks account, now it is the time to play GeoSpark on the Databricks cloud! Please see [GeoSpark notebook on Databricks cloud][Databricks article].
- 11/05/2019: I gave a hands-on tutorial about “Spatial Data Wrangling with GeoSpark: A Step-By-Step Tutorial” in ACM SIGSPATIAL 2019 Spatial API Workshop, Chicago. Please see the slides and coding examples.
- 09/09/2019: I gave a talk about “Geospatial Data Management in Apache Spark” in ApacheCon 2019 North America, Las Vegas. Please see the slides.
- 09/04/2019: We received the Best Demo Paper Runner-Up award at SSTD 2019. The demo features GeoSparkSim, a data system that generates large-scale road network traffic simulations (Certificate).
- 08/15/2019: I will teach a graduate class CSE 511 Data Processing at Scale this Fall semester. This course covers the design, deployment and use of state-of-the-art data processing systems, which provide scalable access to data.
- 08/10/2019: A research paper about “Accelerating Spatial Data Visualization Dashboards via a Materialized Sampling Cube Approach” has been accepted to IEEE ICDE 2020. My paper was one of the few papers accepted directly without revision. The direct acceptance rate is 3%.
- 07/17/2019: Gave a talk at Microsoft Research about “Designing Succinct Secondary Indexes by Exploiting Column Correlations” (video)
