Welcome to Cedar Warman's website

I am an NSF postdoctoral fellow at the University of Arizona where I study plant sexual reproduction in the lab of Dr. Ravishankar Palanivelu. Some of my interests include high-throughput phenotyping, computational biology, and data science. I work to combine computational methods with basic plant biology to answer fundamental questions about how plant reproduction is affected by envronmental stress.

Monitor -80 freezer temperatures and send email alerts with a Raspberry Pi

Do you trust your -80 freezer? I got tired of wondering when mine would fail, so I built a temperature sensor that emails me when there’s trouble. I made an R Shiny app to go along with it for easy visualization of freezer temperatures from any device. Here’s how!

Building a cloud-connected temperature and humidity sensor

Now that you can connect your Raspberry Pi Zero to campus Wifi, what to do with it? How about a simple cloud-connected temperature and humidity sensor? For this project, I combined a Raspberry Pi Zero W with a DHT22 sensor. The DHT22 is a cheap, widely available sensor that can measure temperature with an accuracy of ~0.5 °C and humidity with an accuracy of ~5%. You can read about the DHT22 in wonderful detail here.

Running the Tensorflow Object Detection API in a Singularity container

TL;DR Here’s my Singularity Definition File for the Tensorflow Object Detection API (including X11 forwarding).
