About Cleverson De Souza

Dr. Souza obtained his DVM in 1999 from Universidade Federal do Parana, Brazil, followed by a two-year residency program in Clinical Pathology in São Paulo (UNESP-Botucatu), Brazil. Subsequently, he pursued a Master of Science in Clinical Pathology at Universidade Federal de Santa Maria in Rio Grande do Sul, Brazil. After gaining experience as a veterinary clinical pathologist at Universidade de Passo Fundo in Rio Grande do Sul, Dr. Souza joined Dr. Douglas J. Weiss’s lab at the University of Minnesota to research the molecular pathogenesis of Mycobacterium paratuberculosis. He also completed an accelerated residency in veterinary Clinical Pathology at the same institution and achieved board certification through 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 Brazilian universities such as Universidade de Fortaleza, UniChristus, and Universidade Federal do Ceara. Over the following decade (2013-2023), he held a tenured associate professor position at Washington State University, where he worked as a Clinical Pathologist. Currently, Dr. Souza contributes as an Associate Professor in the Department of Comparative, Diagnostic & Population Medicine at the University of Florida, dedicating his efforts to service, teaching, and research.

Teaching Philosophy
My teaching philosophy is based on evidence-based learning strategies that foster long-term retention and mastery. I believe in creating an engaging environment that encourages active participation, reflection, and self-directed learning. Key elements of my approach include: -Designing active learning experiences through group discussions, problem-solving exercises, and collaborative projects -Incorporating spaced practice and interleaving by revisiting and integrating previously covered material and related concepts -Utilizing retrieval practice through low-stakes quizzes, self-assessment exercises, and peer teaching opportunities -Promoting a growth mindset by emphasizing effort, persistence, and learning from mistakes -Encouraging metacognitive awareness through self-assessment and reflection on learning strategies -Providing timely, specific, and constructive feedback to guide student growth and goal-setting By integrating these principles, I aim to empower students to take ownership of their education, develop lifelong learning skills, and achieve enduring understanding and mastery.
