Daniel Barr, PhD

Current Position: Associate Professor of Chemistry, University of Mary, Bismarck, ND.

Brief Bio

Originally from Philadelphia, PA, Daniel grew up in the Harrisburg area before heading to Arizona State University for his B.S. degree in biochemistry and Ph.D. in computational biophysical chemistry. He is thrilled to be working on the problems that first drew him to a career in science, studying the molecular interactions that govern biological systems. His particular areas of interest are mutation studies of proteins and the mechanisms by which information about structural and binding changes is communicated among various parts of the protein. Daniel’s work spans computational, medicinal, physical, and bio-organic/inorganic chemistry. Passionate about integrating his faith with his work, Daniel is a Benedictine Oblate of Annunciation Monastery and a Catholic Studies Fellow.

In his free time, Daniel and his wife, Priscilla, enjoy spending time with their son, Gabriel, and volunteer with their two therapy dogs, Charlie and Tanner, at local schools and hospitals - "sharing smiles and joy". Daniel also plays the piano, reads voraciously, and enjoys video games as a means of relaxation.

Research Interests

Computational Medicinal Chemistry

- Computational analysis of PRDX6 in collaboration with the SURVE program and Dr. David Ronderos and Dr. James Peliska to elucidate the mechanism of interconnectedness between the two active sites, and the role of mutations in preventing oxidation and activity of the enzyme.

- Molecular dynamics simulations of sequence-specific DNA-binding proteins and peptides to explain the mechanisms of sequence recognition.

- Computational analysis and prediction of pathological mutants of AMPK. Joint project with students in chemistry and biology programs, as well as active collaboration with researchers from the Masonic Medical Research Lab (MMRL) in Utica, NY.

History and Philosophy of Chemistry

- Investigation and historical analysis of chemicals used in gas warfare of World War I.  Joint project with Dr. Joseph Stuart and students from chemistry and history programs to study chemical weapons, gas masks, and the chemical, biological, historical, and sociological aspects of gas warfare.

- Ongoing collaboration with faculty in history, philosophy, and Catholic studies to explore the relationships among the scientific and theological disciplines, particularly in the context of the Scientific Revolution and the meaning it holds for us today.
