Systemic 2 is a software package for fitting and analyzing a variety of exoplanetary data. It consists of a fast, parallelized C library (which you can easily integrate into your own project), an R package providing a high-level interface to the library, and an easy-to-use "IDE" interface for interactive analysis and plotting written in Java. Scientists can use Systemic 2 to either analyze, or reproduce the analysis of, exoplanetary datasets in a consistent, reproducible manner.
Systemic 2 offers interactive model fitting to time series, Lomb-Scargle bootstrapped periodograms, Markov-Chain Monte Carlo and bootstrap uncertainty estimation, cross-validation, access to the GNU Scientific Library set of algorithms, a large library of pre-set plotting, and integrates with RVDB.io for easy access to published data.
Systemic 2 has been used to discover or characterize more than 40 planetary systems.

Systemic Live is a web application that lets you visualize real radial velocity datasets from telescopes all around the world, and try to discover the exoplanetary signals buried in the data. Students, teachers and the general public get a taste of the scientific process of data analysis.
Systemic has become part of curricula of undergraduate and graduate classes at Caltech, University of Florida, University of Texas, MIT, San Jose State University, Delaware, Yale, Columbia, University of California at Santa Cruz, San Francisco State University, and others, reaching >400 students to date, and on the Massive Open Online Course "The Science of the Solar System", taken by ∼13,000 Coursera students.

Super Planet Crash is a browser-based gravity game where players create planetary systems and watch them evolve. The more crowded and chaotic the system, the better!

You are the newest employee of the planet-building company Nova Planetia, working for your short-tempered supervisor, Big Boss Reaz-7. Prove yourself worthy of a promotion by designing planetary systems to the exact specifications of your fickle customers.
Orbits consists of multiple bite-sized levels addressing specific scientific concepts about the motion of planets around stars. The game includes a login system which records students’ progress, and an instructor report system where instructors can check their students’ progress and scores.
GravityKit uses the same engine as Orbits for a free-form gravity simulator.

SAVE/Point (PI: Meschiari) is a collaboration of astronomers and educators dedicated to developing new, innovative games and educational applications to teach astronomical concepts at all levels. Our mission is to create fun, engaging and scientifically accurate educational activities that are widely accessible and on multiple devices and browsers.
We also develop touch applications to install in public spaces as interactive kiosks. Our group received preliminary funding to pilot the installation of five wall-mounted tablets running our suite of applications in 2014-2015. The tablets will be installed on four floors in the Robert Lee Moore building at the University of Texas, which houses the Physics, Mathematics and Astronomy Department and various research centers. Our apps will be available to students enrolled in classes in the building, and to the general public and K-12 students on field trips who might attend public viewing nights with the department telescopes. Additionally, we licensed our game to the Seattle Museum of Flight for use as a stand-alone interactive exhibit on gravity.
Our interactive games were hosted by the James Webb Telescope booth at the 2015 SXSW Gaming Expo.

Curious about Astronomy? Have a burning question about the Universe that you'd like answered?
I created this website to connect K-12 students, teachers, and the general public with a team of graduate students, postdocs, researchers and faculty affiliated with the University of Texas and McDonald Observatory. The most interesting questions are published on this website.

AstroTRENDS is like Google Trends, but for the astronomy literature.
BAM (the Big Article Machine) is a lightweight, elementary, extensible templating language based on Lua. It was used to generate skeletons scientific articles for the Lick-Carnegie Exoplanet Survey.
