About Me

Hello! I'm Yang, a Senior Data Scientist at the Climate Corporation under Bayer. Although my title says I am a "scientist", I see myself more of an architect for designing data/signal processing and visualization strategies for all sorts of agricultural machinery data.

I graduated from Purdue University in August 2021 with a Ph.D. in Electrical Engineering. My strong interests in both agriculture and hardware motivated me to make ISOBlue - a plug-and-play device that helped me collect CAN and GNSS logs from different kinds of ag machinery automagically for my Ph.D. research. I joined John Deere ISG after finishing my Ph.D. and worked on writing embedded software for high-precision GNSS receivers.

Here are a few technologies I've been using recently:

  • C++
  • C
  • Python
  • MATLAB

Where I've Worked

Senior Data Scientist @ The Climate Corporation

Nov 2022 - present
  • Architecting data pipelines for agricultural machine data aggregation, feature engineering, and visualization, with a focus in vector layer pipelines
  • Collaborate closely with stakeholders and downstream users on the delivery of data processing pipelines

Get In Touch

Although I am not looking for a full-time opportunity currently, please feel free to contact me for any ag/farm/embedded hardware related consulting work such as sensor deployment, sensor dashboard setup, and autonomous machine development. I will see if I could help out and it's always fun to chat :)
