• Worked with data analysts and scientists to define data models and analytical approaches to analyze customer data to mine actionable insights for the newsroom.• Used Spark Structured Streaming, AWS S3/Kinesis/EMR/Aurora/ECS/MSK, Kafka, and Druid to develop a cloud data ETL pipeline in Scala that collects, enriches, cleanses, and aggregates custom user-tracking data in web and mobile platforms to inform editors on content performance. The pipeline ingested over 40 million events per day and delivered insights within minutes from user clicks• Optimized PostgreSQL queries and database configurations to achieve better query performance by up to 25 times and reduce costs• Supported the provisioning of pipeline infrastructure and data APIs using Terraform• Collaborated with various teams across the organization to define and advise data strategies. Supported data QA and troubleshooting• Interfaced with product owners and project managers to facilitate the use and leveraging of corporate data in a programmatic way to drive business decisions

Developing interferometric data analysis methods to apply to data from the Askaryan Radio Station in order to search for cosmic neutrinos. Handling physics data processing. Developing physics simulation softwares in C++.

Assisted teaching of Physics 103, general college physics level. Lead discussion sessions and labs.

Develop trigger and filter algorithms for the Askaryan Radio Array, a neutrino telescope at the South Pole using radio detection techniques.

• Built a distributed pipeline on AWS to analyze the Global Database of Events, Language, and Tone dataset. Stored analytics in TimescaleDB and presented spatial and temporal evolution of news sentiments towards user-queried social/political topics (git.io/bubblebreaker)• Used Spark to process 5.2TB of GDELT data from S3. This includes applying text-cleaning techniques for readability and calculating statistics of the most popular topics• Stored computation results with TimescaleDB. Built webapp with Grafana for visualization and easy query

Tested and calibrated digitizer chips for linearity and timing precision.

Under the Fundamental Science Education Program of Taiwan's Ministry of Education, designed and constructed a photon detector using microelectronics techniques and labView.

Researched the star formation of protostellar system IRAS 16293-2422
