​​Call for Judges

The Midwest SETAC board is looking for volunteers to judge student submissions for the Student Best Paper and Platform Competition. During the annual meeting, the best student submissions are determined by a volunteer panel of environmental scientists and Midwest SETAC members via a provided grading rubric. The awards are to be used for student winners to defray costs to attend and present their poster or platform at the annual National SETAC meeting. If you are interested in being a judge, please contact

A hotel block is reserved at the Hampton Inn & Suites La Crosse Downtown at the government rate of $107/night. A limited number of rooms are available on a first come, first served basis, or until March 22. You may book a room in the block online or by calling 608-791-4004 and asking for the SETAC block.

The hotel offers free parking and is approximately 1 mile from the UW-La Crosse campus, where the conference will be held. There is also a free shuttle from the airport that can be arranged with the front desk staff at the hotel by calling 608-791-4004.

​​scientific improv

We are excited to try a new session this year - Scientific Improv! Each volunteer will have 3 minutes to present their research, scientific work, job field, career, etc. in short, engaging terms without using any scientific jargon. We encourage you to make it fun - write a poem, bring a song, tell a story, or give an elevator speech. The crowd will have clappers and can make noise if they think your terms are getting too in the weeds. We will be asking for volunteers on Thursday, but if you already know you'd like to participate with a short talk please tell the Board members at check in!

Introduction to Fitting Dose-Response Curves with R

When: Thursday, April 11, 9:30-11:30

Cost: Free with early bird registration! ($15 after March 8)
Who may be interested: all ranges of R users who want to learn dose-response modeling curves

Ecotoxicologists and environmental chemists commonly use dose-response curves (and related curves such as exposure response curves) to understand the relation between toxicants and effects (such as survival, growth, or similar endpoints). These curves allow estimation of values such as LC50s and EC99s or similar estimates. They also provide an alternative to NOECs and similar endpoints. The curves may also be used to predict toxicity given new concentrations or doses.

This course will provide an overview of the using the dose-response curve (drc) package in R. The course will progress through how to read in data into, fit and understand the models, and then present model results both numerically and graphically. For novice R users, the course will include all code for examples from reading in data to plotting the results. The course will also include tips for how to learn gaps (such as formatting data). For advanced R users, the course will also include tips such as how to use the package with ggplot2 for plotting and using R Markdown/Quarto to create reproducible reports. Code from a previous version of the course may be found online at and this code will be updated prior to the course. Course participants may optionally code along with their own laptops.
