The main topics that will be covered are:
- Experimental design to test one-to-one relationships
- Isolating relationships from a complex context
- Disturbances in field and on-farm experiments
- The fragmentation of knowledge within experiments and institutions
- Short and long-term experiments
- Multidisciplinary, transdisciplinary and holistic studies
- Dealing with outliers and empirical deviations and the focus on averaged results

Introduction to concepts of Bayesian Statistics
This course will provide an overview about methods of Bayesian statistical inference. The class has a humble objective: that students learn (or are at least become aware) of the vocabulary, terminology and concepts regarding this type of statistical inference, which has increasingly grown in popularity in scientific literature. Explanations to the terms and concepts, as well as some hands-on data processing will be included. Calculations would not be the core of the course; however, the analysis of datasets using R, JAGS and Stan are going to be covered during the labs. The evaluation will be based on quizzes.
It is recommended that students interested in the class have already taken a course of basic statistical methods (experimental design is not necessarily but a course on descriptive statistics is required) and have some experience with the Statistical Language R.
The main topics that will be approached are:
- Refresh of probabilistic distributions
- Bayesian inference,
- Linear models
- Model comparison
- Application and introduction to Markov chain monte Carlo (MCMC)
- Introduction to categorical/count models
- Introduction to hierarchical models

Then students will synthesize the information to present to other peer students in the course and also develop a corresponding impact statement of the finding to better communicate with the relevant industry stakeholders. The goal of this course is to get the most up-to-date understanding of the controlled environment crop physiology research and communicate the impact effectively in a public space.
Course learning outcomes
- Become familiar with the current research status of applied plant physiology under controlled environment
- Become familiar with the current and potential technological applications of applied plant physiology under controlled environment
- Develop skills of analytical thinking through evaluating methods and results reported in peer-reviewed journal papers
- Learn how to translate scientific findings and potential impacts in layman’s language.

Extraction, Separation, Identification, and Quantification of Plant Compounds
appreciate theoretical and practical aspects of chromatography (TLC, GC, HPLC, FPLC) and electrophoresis, as well as spectrophotometric assays designed to measure purity and activity of extracted compounds. They will also understand how tissue, cell, organelle complexity affects extraction of desired compounds and recognize optimal choices to maximize yields and purity of desired compounds. The importance of sampling error and how to minimize it; and the importance of both replication and the use of proper controls (e.g., internal and external standards) will also be emphasized.
