### Stephen Wolfram

Stephen Wolfram is the author of *A New Kind of Science* and the principal lecturer at the Summer School. He is the creator of *Mathematica*, the creator of Wolfram|Alpha, and the founder and CEO of Wolfram Research. Having started in science as a teenager (he got his PhD at age 20), Wolfram had a highly successful early career in academia. He began his work on NKS in 1981 and spent ten years writing the NKS book, published in 2002. Over the course of 30 years, Wolfram has mentored a large number of individuals who have achieved great success in academia, business, and elsewhere. Starting the NKS Summer School (now called the Wolfram Science Summer School) was his first formal educational undertaking in sixteen years.

### Todd Rowland—Academic Director

Todd Rowland assisted Stephen Wolfram with mathematical issues found in *A New Kind of Science* chapters 5, 9, and 12. Before joining the NKS team in 2001, he wrote entries for *MathWorld*. Todd received his PhD from the University of Chicago in 1999, where he studied traditional mathematics, such as algebraic and differential geometry. Currently, he is the managing editor of *Complex Systems*. His interests include automated theorem proving, the fundamental theory, and NKS education.

### Catherine Boucher—Program Director

Catherine Boucher joined Wolfram Research in 1998. She led project management during the production of *A New Kind of Science* and is currently the director of special projects for Wolfram Research. Her team is responsible for early development of new initiatives at Wolfram Research, along with projects related to Wolfram Science. She and her team led the original development of Wolfram|Alpha and currently handle its mathematical content and parser development. Catherine received her PhD in applied mathematics from the University of Massachusetts Amherst, specializing in cluster analysis.

### Abigail Nussey—Event Director

Abigail Nussey joined Wolfram Research in 2007. She has a bachelor's degree in physics (2004) and a master's degree in math (2007) from Boston University. She has been involved in the Wolfram Science Summer School for five years: five years as event director, two years as a participant, one year as teaching assistant, and one year as an instructor. She presented on cellular automata over graph topologies at the 2008 Midwest NKS Conference, which was later written into an article and published in *Complex Systems*. She paints, sings classical soprano, and writes speculative fiction.

### Carlo Barbieri

Carlo Barbieri holds a PhD in physics from ENS in Paris. His current research interests are on the boundary between physics, biology, and informatics. During his thesis "Inverse problems in biophysics," he worked on developing algorithms to extract biologically relevant information from biophysics experiments such as DNA micromanipulation or neural activity recordings. He spent one year as a visiting PhD student at the Institute for Advanced Study in Princeton. He earned a master's in physics from the University of Rome "La Sapienza", in his home town, focusing on Boolean satisfiability and the statistical physics of complex systems.

He now works for Wolfram in the ARG group (also known as the Talk-Like-A-Pirate group) on the data input features in Wolfram|Alpha. He has written a blog post on his experience at the Summer School last year.

He is a music lover, an avid traveler, and a bike maniac. He finds it weird to talk about himself in the third person.

### Taliesin Beynon

Taliesin Beynon is a research programmer in the advanced research group at Wolfram|Alpha. His research interests include machine learning, natural language processing, data mining, and Dataviz. His previous NKS work has focused on graph automata and two-dimensional Turing machines.

### Erin Craig

Erin Craig graduated from New College of Florida with a BA in mathematics. Inspired by the beauty of both algebra and automata, she spent her final year of college at University of California, Berkeley exploring an extension of rule 90 to cellular automata over non-Abelian groups. Erin attended the NKS Summer School in 2009, where she explored reducibility of string substitution systems. She joined Wolfram Research as a software developer in 2009.

### Vitaliy Kaurov

Vitaliy Kaurov received his PhD in theoretical physics from The City University of New York. He was an assistant professor at the College of Staten Island, where he taught math and physics and did research in the physics of ultra-cold quantum gases. Participation in the Wolfram Demonstrations Project rekindled the old interest in NKS that he had carried since his undergraduate studies in Ukraine. He attended the NKS Summer School 2010, where he investigated the relation between 1D and 2D cellular automata. He joined the technical communication and strategy group at Wolfram Research in 2010.

### Paul-Jean Letourneau

Paul-Jean Letourneau attended the NKS Summer School 2004, where he completed a pure NKS project on elementary cellular automata with memory. He has been an instructor at the Summer School since 2005. His 2004 project developed into his master's thesis in theoretical physics, "Statistical Mechanics of Cellular Automata with Memory." He has worked in several industrial and academic laboratories around North America, where he made original contributions to real-world problems in medical imaging, geophysical seismic imaging, protein structure prediction, and DNA-protein interactions. Paul-Jean is now lead developer of computational biology for Wolfram|Alpha.

### Hernan Moraldo

Hernan Moraldo is a developer in Wolfram|Alpha's Advanced R&D Group (ARG). Within Wolfram|Alpha, he worked in many projects related to parsing and data processing (also including some managing, briefly). Previously, he worked for a number of years in the computer games industry, and was a co-founder and member of the board of the Argentine Game Developers Association (ADVA in Spanish). He taught courses on computer game development and in artificial intelligence for games in Universidad Maimonides, in Instituto Image Campus, and in Escuela Da Vinci.

Hernan is greatly passionate about technology and innovation; he's especially interested on different forms of automation (based on automatic data processing and analysis, language, vision, robotics, etc.). He lives in Buenos Aires, Argentina.

### Eric Rowland

Eric Rowland is a postdoc at the Université du Québec à Montréal. His research interests lie at the intersection of number theory, combinatorics, and theoretical computer science. In the summer of 2006 he worked as an R&D Fellow at Wolfram Research on an early version of Wolfram|Alpha, and he continues to work on geometry functionality in Wolfram|Alpha.

### Matthew Szudzik

Matthew Szudzik made significant contributions to *A New Kind of Science* from 1998 through 2000 and during the summer of 2001 as a research assistant to Stephen Wolfram. His work focused primarily on the analysis of simple programs and on the theoretical foundations of computational mathematics. He holds a PhD in mathematical logic from Carnegie Mellon University and is an assistant teaching professor of mathematics at their campus in Doha, Qatar.
