Ehringer, Marissa A



Research Areas research areas


research overview

  • Dr. Ehringer's research is aimed at identifying and understanding genetic underpinnings associated with substance use disorders (alcohol, nicotine, opioids). One component of her work is to study variations in the human genes that have been associated with substance use behaviors in order to understand the underlying biology. Her laboratory uses human statistical genetics and molecular approaches to study the biological mechanisms that may be influenced by differences in genes. She also uses rat and mouse models to study genetic factors contributing to substance use behaviors.

selected publications


courses taught

  • IPHY 2800 - Introduction to Statistics
    Primary Instructor - Fall 2019
    Examines the application of statistics to research relevant to integrative physiology. Includes instruction and hands-on experience with related computer programs and interpretation of the results of their use. Recommended prerequisite: MATH 1300.
  • IPHY 3280 - Intro to Data Science and Biostatistics
    Primary Instructor - Fall 2020 / Fall 2021
    Builds a foundation for modern data analysis and experimental design in the context of human physiology, health and disease. An intuitive understanding of probability, statistical methods, test outcomes and data relationships are emphasized over rigorous mathematical proofs. Foundational analytical skills using R and R Studio are developed using real and simulated data.
  • IPHY 4870 - Honors Thesis
    Primary Instructor - Spring 2018
    Department enforced prerequisites: IPHY 2800 and IPHY 3700.
  • IPHY 4930 - Internship
    Primary Instructor - Spring 2022
    Provides an opportunity for field/laboratory work in a variety of different settings. Consult with faculty for approval. May be repeated up to 6 total credit hours. Department enforced prerequisite: completion of at least two of the major core classes.
  • IPHY 5100 - Colloquium in Integrative Physiology
    Primary Instructor - Fall 2023 / Spring 2024
    May be repeated up to 6 total credit hours.
  • IPHY 5262 - Application of Bioinformatics and Genomics
    Primary Instructor - Spring 2019 / Fall 2022
    Explore public websites, databases, and bioinformatic tools that can be used for analysis of genomic data. These include NCBI Resources, genome databases, gene expression databases, tools for nucleotide and algorithms analyses and protein databases. Students develop a mini-grant proposal that is required to incorporate use of some of the tools covered. Recommended prerequisite: IPHY 5200 and IPHY 5102.
