- Dr. Toledo is a bioinorganic chemist with a passion to uncover the role that metals play in biological systems. His research team focuses on two main themes: a. the synthesis and reactivity of biomimetic models of metalloenzymes with the goal of understanding the role that metalloenzymes play in disease states including cancer development and neurodegenerative diseases. b. the design of bioinspired catalysts to promote challenging oxidative transformations for use on environmentally relevant degradation of organic compounds. The Toledo lab uses a variety of synthetic (organic and inorganic), and spectroscopic tools to characterize and understand these novel bioinspired inorganic complexes. Dr. Toledo is also passionate about student learning. He is interested in course design structures that promote equitable and inclusive learning environments. His work focuses on the use of clearly delineated student learning outcomes built around taxonomies of learning. Additionally, he has done extensive work on alternative grading methodologies including standards and SPECS based grading. Dr. Toledo consults with colleagues nationally and internationally on these matters. Dr. Toledo obtained his Ph.D. from the University of Washington, Seattle, under the supervision of Dr. Julie Kovacs. He graduated with a B.S. in Chemistry from Texas Lutheran University, where he worked under Dr. John McClusky. Dr. Toledo has worked in the academy for over 15 years initially in his alma matter, Texas Lutheran University. He then moved to St. Edward’s University where he served as Department Chair from 2019-2022. He is a native of Quito, Ecuador, he loves running, hiking, fútbol and his amazing family.
