He has taught tutorials and short courses on high performance computing at many conferences and institutions in Europe and the U.S. He holds an M.Sc. degree in electronics and computer engineering, and a Ph.D. in mathematics, both from the University of Rome “Tor Vergata.”

Mary Ann Leung

Mary Ann Leung is a computational chemist whose scientific experience is complemented with sixteen years of experience in the software industry. Her research interests include the development of scalable, parallel, scientific codes for the investigation of quantum mechanical phenomena. As Program Manager for the Department of Energy (DOE) Computational Science Graduate Fellowship (CSGF) program, Dr. Leung evangelized the use of high performance computing by developing HPC workshops, training and mentoring, and increasing usage of DOE supercomputing resources. Under her directorship, the National Science Foundation (NSF) Science Technology Engineering and Mathematics Talent Expansion Program at Miami Dade College witnessed development and implementation of novel programming for cross-engagement of women and under-represented minorities in STEM. She graduated with honors from Mills College, earning a B.A. in Chemistry with a Math minor. Dr. Leung holds a Ph.D. and an M.S. in Computational Physical Chemistry from the University of Washington.

Karla Morris

Karla Morris is a mechanical engineer who has taught as an Adjunct Professor at the Borough of Manhattan Community College and at The City College of New York (CCNY).  She conducted Post-Doctoral research at CCNY’s Benjamin Levich Institute for Physico-chemical Hydrodynamics. She is currently a senior member of technical staff in the Reacting Flow Research Department at Sandia National Laboratories. She is the lead developer of ForTrilinos, the object-oriented Fortran 2003 interfaces to Trilinos.  ForTrilinos provides Fortran applications direct access to capabilities in the Trilinos project. Her research includes computational fluid dynamics for multiphysics flows and scientific software architecture. She is also the lead developer of a scalable, open-source framework, to support a platform independent, application-programming interface for computational modeling of multiphase flows. Morris holds Ph.D., M. Phil., M.E. and B.E. degrees in Mechanical Engineering from The City University of New York.

Dan Nagle

Dan Nagle is a scientific programmer who has been using Fortran since 1970 and teaching it since 1982. He conceived, produced and taught workshops on using the Cray-1, Cray XMP, Cray-2, Cray YMP, Cray T3D/E, ESCD ES-1, Myrias SPS-2, and KSR KSR-1 computers, facilitated modernization of numerical applications and oversaw migration of programs to parallel processors at a DoD HPC center, and produced a series of Technical Notes on topics in modern numerical programming. He has been a member of PL22.3 (US Fortran standards committee) since 1999, and its Chair since 2002. He holds a B.S. and M.S. in Physics from Virginia Tech, and a Ph.D. in Computational Science from George Mason University, with an emphasis in High Performance Computing.

Vanitha Sankaran

Vanitha Sankaran is a scientist in the area of biomedical science and optics. She has expertise in the measurement and modeling of light interactions with tissues, both for understanding how to determine structural abnormalities in tissue and to study changes in tissue function in response to stimulus. She has been the Co-PI on research funded by the National Institutes of Health and grants funded by Lawrence Livermore National Laboratory, and has given invited talks on her work worldwide. More recently she has concentrated on scientific communications in provate, nonprofit and government organizations. She holds a B.S. in Optical Engineering from the University of Arizona, an M.S. and Ph.D. in Biomedical Engineering from Northwestern University, and an M.F.A. in Writing from Antioch University.


Hari Radhakrishnan

Hari Radhakrishnan is a research scientist focusing primarily on computational fluid dynamics: biomedical flows, turbulence modeling, LES and DNS solvers, and parallel programming. He has participated in several research projects, and has helped to coordinate five projects funded by the EU and Cyprus. His current research work includes using coarray Fortran to parallelize legacy codes and benchmarking of coarray Fortran performance against MPI. He has a B.E in Paper Science and Technology from IIT Roorkee, India and a Ph.D. in Chemical Engineering from the University of Minnesota.


Izaak Beekman

Izaak Beekman is a doctoral candidate in the Mechanical and Aerospace Engineering Department of Princeton University.  His dissertation research involves the direct numerical simulation (DNS) of supersonic and hypervelocity turbulent boundary layers.  This research entails running very large computational fluid dynamics (CFD) simulations on high performance computers (HPCs) using an in-house WENO code, originally developed by his PhD advisor.  Izaak also has interests in software engineering and software architecture for scientific computing.  In computational science and engineering, all too often numerical software is written by scientists, engineers and mathematicians with little or no background in software engineering.  While functional, these software packages can be difficult to maintain or enhance and can incur unneeded expenses and frustration.  This frustration spurred Izaak’s research in scientific software engineering and architecture, as well as generic programming.

Alessandro Fanfarillo

Alessandro Fanfarillo is a Ph.D. candidate in Computer Science, Control, and Geoinformation at University of Rome “Tor Vergata”. He is interested in parallel computing, more specifically his research focuses on how to exploit heterogeneous architectures, CPU+Accelerators, and Partitioned Global Address Space (PGAS) languages (in particular Coarray Fortran) for scientific purposes.

He is also the lead developer of OpenCoarrays, the open-source library that implements the coarray support in the GNU Fortran compiler.

He holds a B.S. and M.S. in Computer Engineering both from University of Rome “Tor Vergata”.
