J. V. Ortiz was born in Bethpage, New York in 1956 and attended public schools in Plainview, New York until 1973. After obtaining a B.S. in Chemistry with High Honors at the University of Florida in 1976, he began graduate work in the Quantum Theory Project of the same university and completed his dissertation in 1981 under the supervision of Yngve Öhrn, earning a Ph.D. in Chemistry with a certificate in Chemical Physics. After two years as a postdoctoral fellow at Harvard University with William Lipscomb and at Cornell University with Roald Hoffman, he spent thirteen years at the University of New Mexico. In December, 1996, he joined the Chemistry Department of Kansas State University and was named a University Distinguished Professor in April, 2004. He became the first Ruth W. Molette Professor of Chemistry and Biochemistry at Auburn University in August, 2006 and simultaneously began serving as Chairman of the Department of Chemistry and Biochemistry.

Dr. Ortiz has taught a variety of topics, from basic chemistry for nontechnical majors to advanced methods of quantum mechanics. He supervises a research group of graduate students and postdoctoral fellows that specializes in his area of research, quantum chemistry. This field is concerned with the prediction and explanation of the properties of atoms, molecules and solids using computers, principles of physics and mathematical methods. His group is engaged in the derivation and programming of new quantum mechanical methods for calculating molecular spectra. A special emphasis has been the development of ab initio propagator theories which combine the rigor of many-body formalisms with chemically perspicuous orbital concepts. Recent applications have included molecules of importance in biochemistry (e.g. nucleotides, porphyrins) or materials science (e.g. fullerenes, polysilanes, aluminum oxide clusters), gas-phase species with unusual electronic structure (e.g. double Rydberg, multiply charged and diffusely bound anions) and small anions embedded in solvents. Professor Ortiz has published more than 210 papers in scientific journals, has delivered over 180 invited lectures, is among the authors of the widely used Gaussian quantum chemistry packages, is a member of the Editorial Board of the International Journal of Quantum Chemistry, has served on the Editorial Board of the Journal of Chemical Physics and is a consultant to federal agencies and private research organizations. He is a member of the American Chemical Society, the American Physical Society, the International Society for Theoretical Chemical Physics, the World Association of Theoretically Oriented Chemists, the American Association for the Advancement of Science, the American Association of University Professors and the National Organization for the Professional Advancement of Black Chemists and Chemical Engineers (NOBCChE), has been a Fellow of the Japan Society for the Promotion of Science and has received the Commerce Bank Distinguished Graduate Faculty Award, the Erwin W. Segebrecht Distinguished Faculty Achievement Award and the NOBCChE President's Award .
