**Summary**

Dr. Jonathan Ziprick is a faculty member in the ACE (Applied Computer Education) Department at Red River College. He has a PhD in Physics from the University of Waterloo, and more than 10 years experience doing research across both academia and industry, in the varied fields of computer science, mechanical engineering, physics and mathematics. Dr. Ziprick has supervised both undergraduate and graduate students in research projects leading to publications in high impact journals.

**Research**

Dr. Ziprick is able to supervise research projects in:

- machine learning
- precision farming and digital agriculture
- image processing
- mathematical modelling
- numerical methods for partial differential equations
- quantum information/computing
- quantum gravity

The following projects have open student positions:

: There are two different streams of research required here:*Plant Phenotyping**Robotics*: Students working on this aspect will build an automated camera system, installed on a greenhouse bench seeded with a particular plant species, capable of capturing images of plants from a variety of angles, at a variety of light frequencies, at all stages of growth.*Machine learning*: Students working on this aspect will train deep neural networks on a large set of labelled images of plants. The goal is to develop software capable of identifying a particular plant from an image, and to evaluate the health of the plant.

: Students working on this project will use a decision tree to determine which teaching techniques are most effective for different types of learners.*Peer-to-Peer Learning*: The goal of this project is to build a deep neural network from the bottom up and quantitatively test different constructions that are commonly in practice, and to innovate in order to improve on existing models.*Deep Neural Networks*

Students who would like to work on these projects are encouraged to contact Dr. Ziprick by email at jziprick@rrc.ca
