John D. Mark
Clinical Professor, Pediatrics - Pulmonary Medicine
BioDr. Mark received his medical degree from the University of Kansas and completed his residency in pediatrics at Children’s Mercy Hospital in Kansas City, Missouri. He then completed a fellowship in pediatric pulmonary medicine at the University of Rochester, Rochester, New York. In 1984, Dr. Mark completed the first fellowship in Pediatric Integrative Medicine at the University of Arizona om 2001. He practices at Packard Children’s Hospital where he utilizes non-pharmaceutical approaches with patients with chronic pulmonary disorders such asthma and cystic fibrosis. He is interested in nutrition, lifestyle changes, exercise and mind/body approaches to healing in an effort to decrease dependence on medication and improve overall lung health.
Dr. Mark is the past Program Director for the Pediatric Pulmonary fellowship program, Co-Director for the Pediatric Integrative Medicine fellowship program and the Medical Director for the Coordinating and Optimizing Resources Effectively (CORE) Program at Packard Children’s Hospital, Stanford University. This innovative program assists with care coordination and communication with all health care providers for children with complex medical needs. Dr. Mark is also the Chair of the Credentials Committee at Packard Children's Hospital. -
Thomas E. Markland
Professor of Chemistry
Current Research and Scholarly InterestsOur research centers on problems at the interface of quantum and statistical mechanics. Particular themes that occur frequently in our research are hydrogen bonding, the interplay between structure and dynamics, systems with multiple time and length-scales and quantum mechanical effects. The applications of our methods are diverse, ranging from chemistry to biology to geology and materials science. Particular current interests include proton and electron transfer in fuel cells and enzymatic systems, atmospheric isotope separation and the control of catalytic chemical reactivity using electric fields.
Treatment of these problems requires a range of analytic techniques as well as molecular mechanics and ab initio simulations. We are particularly interested in developing and applying methods based on the path integral formulation of quantum mechanics to include quantum fluctuations such as zero-point energy and tunneling in the dynamics of liquids and glasses. This formalism, in which a quantum mechanical particle is mapped onto a classical "ring polymer," provides an accurate and physically insightful way to calculate reaction rates, diffusion coefficients and spectra in systems containing light atoms. Our work has already provided intriguing insights in systems ranging from diffusion controlled reactions in liquids to the quantum liquid-glass transition as well as introducing methods to perform path integral calculations at near classical computational cost, expanding our ability to treat large-scale condensed phase systems.
