About Cleverson De Souza

Dr. Souza obtained his DVM in 1999 from Universidade Federal do Parana, Brazil. He then completed a two-year residency program in Clinical Pathology at São Paulo State University (UNESP-Botucatu) in Brazil. Subsequently, he pursued a Master of Science in Clinical Pathology at the Federal University of Santa Maria in Rio Grande do Sul, Brazil. After gaining veterinary clinical pathology experience at the University of Passo Fundo in Rio Grande do Sul, Dr. Souza joined Dr. Douglas J. Weiss’s lab at the University of Minnesota. There, he researched the molecular pathogenesis of Mycobacterium paratuberculosis and completed an accelerated residency in Veterinary Clinical Pathology, achieving specialty board certification from the American College of Veterinary Pathologists (ACVP).

Between 2009 and 2012, Dr. Souza shared his expertise in general pathology with MD and DDS students at various Brazilian universities, including the University of Fortaleza, UniChristus, and the Federal University of Ceará. Over the following decade (2013-2023), he held a faculty position at Washington State University (2019-2023 as a tenured associate professor), serving as a clinical pathologist.

Currently, Dr. Souza is an Associate Professor in the Department of Comparative, Diagnostic, and Population Medicine at the University of Florida. He dedicates his efforts to service, teaching, and research.

Teaching Philosophy
My teaching philosophy centers on evidence-based learning strategies that promote long-term retention and mastery. I aim to create an interactive, inclusive environment focused on participation, reflection, and self-directed learning through real-world group projects and discussions. In the near-term, I plan to incorporate AI tools to personalize and adapt to individual students’ needs. Specifically, I will leverage AI to connect new and old content, provide quick feedback, and give insights into student progression. Moving forward, I wish to fully integrate AI to build metacognitive skills for self-assessment and strategy adjustment. Overall, my approach looks to empower students to own their continual learning process, equip them with technological skills for lifelong success, and motivate them to learn with a growth mindset focused on effort and mastery.
