Brief biography
I revieved a PhD from Iowa State University in Applied Mathematics in 2012. Prior to that I revieved a bachelors degree from Minnesota State University - Mankato in Mathematics and Computer Science.
I am currently an Assistant Professor of Mathematics at the UWL where my interests include:
- teaching undergraduate mathematics with special emphasis on applications,
- co-organizing a student research group on Machine Learning and Data Science,
- researching cutting machine learning techniques and applying ideas to business and marketing,
- and collaborating with local companies on research and student opportunities.
