Since 2013, the Office of Undergraduate Research bestows the Research Mentor of the Year award to acknowledge outstanding efforts by UWM Faculty of Staff for supporting undergraduate researchers. This year, Prof. Arnold received this award for his continuous support of undergraduate research enabling students to gain knowledge in the field of drug discovery and development. Since 2009, Prof. Arnold has mentored almost a hundred undergraduate students, which worked together with members of the Arnold Research Group developing new drug candidates for cancer, respiratory and cardiovascular diseases. Their dedication and work resulted in numerous poster presentations and peer-viewed publications improving their career prospects and strengthening the R1 status of UWM.
