Current opportunities

Here is a partial list of faculty who are actively involved in undergraduate research in our department. Please feel free to talk with our faculty either face to face or via email to discuss your involvement with undergraduate research.

  • Leon Arriola (, LT 2233)
    Research interests: interest, interest, interest.

  • Balamurugan Pandiyan (, LT 2240)
    Research interests: interest, interest, interest.

  • Khyam Paneru (, LT 2228)
    Research interests: statistical modeling and computing.
    Currently Dr. Paneru is working on developing regression models in zero-inflated populations. In many applications a population may contain a large proportion of zero values, which causes the distribution to spike at zero; such a population is called a zero-inflated population. Presence of these populations makes it difficult to estimate the mean of the total range of values. His students are applying the technique of "bootstrapping" to estimate population parameters with bootstrap confidence intervals.

Current projects:

  • Modeling healthcare cost, quality, and efficiency
    Student: Brittany Greuel
    Faculty Advisor: Balamurugan Pandiyan
    Description: Hospitals and healthcare providers are interested in three quantities: cost, level of care, and efficiency. We develop a simple mathematical index that describes the relationshios between healthcare cost, quality, and efficiency. Efficiency means healthcare effectiveness; quality means patient satisfaction; quantity means treatment cost.

  • Modeling slow growth of thyroid nodules and initiation of cancer
    Student: Daniel Lollar
    Faculty Advisor: Balamurugan Pandiyan
    Description: Thyroid nodules coexist with Hashimoto's thyroiditis and grow slowly as thyroid-stimulating hormone (TSH) increases above the normal value (>4 mU/L). About 5 to 15 percent of thyroid nodules become cancerous. In this project, we develop a stochastic model for the formation of thyroid nodules and initiation of cancer in nodules for patients with Hashimoto's thyroiditis.
