Research Focus & Interests  

Dr. Holtkamp’s research focuses on biosecurity as well as the economics and risk management of swine disease with an emphasis on PRRSV and PEDV. He has developed standard procedures for conducting and reporting on outbreak investigations and uses them to conduct outbreak investigations for PEDV and PRRSV. He coordinates the Rapid Response Program which was developed with funding from the Swine Health Information Center to help the pork industry prepare for the next transboundary disease introduced into the US.


Director of the Swine Veterinary Internship Program (SVIP) at Iowa State University. SVIP provides summer internships for veterinary students to help them help them acquire field-based research skills, establish a network of future colleagues, reduce their student debt and increase the value of their DVM degree to help them pay off the debt after graduation.
