Our Leadership Team

SCOTT KRUGER, PH.D.

Chief Executive Officer

Dr. Scott Kruger, CEO, is a distinguished physicist and project manager who has been with Tech-x since 2004. He has a PH.D. in fusion research from the University of Wisconsin-Madison, and before joining Tech-X, he worked for Science Applications International Corporation (SAIC) in San Diego.

 

At Tech-X, Dr. Kruger managed a group of physicists and mathematicians as the former VP of the fusion group. Additionally, his list of accomplishments includes being a former project manager for FACETS, a large (> 5M lines of code) fusion application that integrated legacy Fortran codes with a C++ framework, and being a current project manager for NIMROD magnetohydrodynamic code. In his time at Tech-X, Dr. Kruger has developed new company procedures for improving the communication between research scientists and the support groups within Tech-X to more efficiently deliver cutting-edge research codes to the commercial marketplace.

JOHN R. CARY, PH.D.

Chief technology Officer

Dr. John R. Cary, CTO, co-founded Tech-X in 1994. The company’s products help in the design and prediction of systems involving electromagnetics and plasmas. Tech-X has contracts from industry and the government, with multiple lines of software products.

Dr. Cary has a strong background in computational research and development, with more than 150 publications. His background helps ensure that Tech-X products are based on the most recent and advanced algorithms and computing developments, make use of the most advanced computing platforms and are easily used by Tech-X customers.

Dr. Cary received his degrees at the University of California at Irvine and at Berkeley. He has worked for government labs (Los Alamos), in the private sector (Tech-X), and in academia (he retains his position as Professor of Physics at the University of Colorado at Boulder, where he continues to be involved in the education of the next generation of scientists and engineers).

David Alexander, Ph.D.

VP of User Interactions

Dr. Alexander received a B.S. in Physics from the University of Washington in 1990 and his Ph.D. in Physics from the University of Colorado in 1996. Dr. Alexander continued on at the University of Colorado as a post-doctoral researcher developing an interactive web-based visual learning interfaces in the academic area of planetary science for the Solar System Collaboratory Project.

Joining Tech-X Corporation in 1997 he initially developed interactive educational software and has produced a commercial package and published in this area.  With further work at Tech-X, he has become an expert in graphical user interfaces for scientific codes and usability of workflows associated with them and is the original developer of the Composer Toolkit.  He also has experience in client-server systems and distributed technologies, as well as, automated building and testing system as the Directory of Quality Assurance and Releases.

Jarrod Leddy Ph.D

VP for Particle Modeling

Dr. Jarrod Leddy is a plasma physicist with a background in Applied Physics, Science Education, and Plasma Physics. After completing his undergraduate studies at the Georgia Institute of Technology in 2008, he began teaching high school AP Physics and Math while obtaining an MA in Science Education from Georgia State University. During this time, he discovered his interest in research and moved to England to earn his MS and Ph.D. in plasma physics from the University of York. Upon finishing his postdoctoral work at the University of York, he returned to America. He began working with Tech-X in 2017, developing VSim code and researching low-temperature plasmas, accelerator physics, and fusion energy. Currently, Dr. Jarrod Leddy is the VP for Particle Modeling and leads a team of great scientists researching and developing new techniques for physics simulation modeling.

Larry Nelson

Controller

Mr. Nelson received a B.S. in Accounting from the University of Colorado (CU) at Boulder in 1969. After a one-year position at a bank in Denver, he became employed at CU, initially in the Accounting Department, and soon thereafter in the Office of Contracts and Grants (OCG). OCG is responsible for processing and administering all of the sponsored research proposals and awards at CU (more than $250 million annually). In 2001, Mr. Nelson was a recipient of the University of Colorado’s Robert L. Stearns Award for Exceptional Service, the highest honor bestowed upon CU faculty and staff for exceptional teaching, research, or service.

In 1981, Mr. Nelson became the Director of OCG and served in that capacity until his retirement in 2004. In February 2005, Mr. Nelson joined Tech-X as its first Controller. He brings to Tech-X his 34 years of experience with sponsored research, federal funding, and contract management.
