Stefano Costanzi
|
Dr. Costanzi鈥檚 current scholarly work is based on two main research lines. The first one focuses on the application of computational chemistry to the study of the . The second one focuses on the analysis of gaps in current and the conceptualization of ways to narrow them.
Douglas Fox
Dr. Fox develops commercial and industrial products using sustainable materials. Our lab currently investigates new flame retardants, coatings, fiber reinforced plastics, and the health and safety (EHS) of nanomaterials.
Matthew Hartings
听触听
Dr. Hartings has two main laboratory research projects: 1) The use of 3D printing to create chemically reactive objects and 2) The development of novel environmental and biological sensors based off of stimulus-responsive materials. Dr. Hartings is also active in studying and communicating about all of the wonderful chemistry we do at home in our kitchens while we cook.

Monika Konaklieva
Dr. Konaklieva鈥檚 main research interest is in the area of using organic synthesis and evaluation towards the generation of new antibacterial, antiviral agents and lipoprotein metabolism modulators. Within this research, the group aims to develop efficient and environmentally friendly synthetic approaches for their preparation. Interdisciplinary projects are a main focus in the Konaklieva鈥檚 group, involving organic synthesis/medicinal chemistry, biochemistry, and structure-based drug design.听
Santiago Toledo
Research in the听Toledo lab focuses on two main themes:听a.听the听synthesis and reactivity of听biomimetic models of metalloenzymes with the goal of understanding the听role that metalloenzymes play in disease states听including cancer development and neurodegenerative diseases;听b.听the design of bioinspired catalysts听to promote challenging oxidative transformations for use on environmentally relevant degradation of organic compounds.
