42 Interactive announces a partnership with ApolloMed ACO to bring its unique, next-generation analytics solution to Apollo's patients.
"We believe that analytics will play a transformative role in healthcare in the near future and especially in population health management. 42 Interactive's unique platform will help us further identify our highest risk patients so we can assign care managers and clinicians to them and intervene in their care before they deteriorate," stated Warren Hosseinion, M.D., Chief Executive Officer of Apollo Medical Holdings. "These interventions should significantly reduce avoidable hospitalizations, improve patient outcomes and save millions of dollars in healthcare costs."

Who we are

42 Interactive was created by a group of computational neuroscientists from Caltech and Harvard.

Chess Stetson, Ph.D.

Chess Stetson, Ph.D., did his doctoral (2012) and post-doctoral work in Computation and Neural Systems at Caltech, studying the oscillatory relationship between cortical regions and using signals from individual neurons to predict decisions. Previously, he studied the basis of neural time processing. He earned an AB in Physics from Harvard College, (2001) and an MS from the University of Texas (Houston Medical Center, 2006). He also worked as an engineer at MIT Lincoln Laboratory and the Smithsonian Astrophysical Observatory, building instrumentation for air- and rocket-borne experiments. And, he has appeared several times as a neuroscience expert on National Geographic.

Boris Revechkis, Ph.D.

Boris Revechkis received his PhD (2015) in Computation and Neural Systems from Caltech. There, Boris investigated the use of the parietal lobe for neural prosthetics, a.k.a. brain-machine interfaces, examining the role of parietal areas in motor function and self-monitoring. These experiments allowed paralyzed patients to control avatars in 3D virtual reality directly with their neurons, i.e. just by thinking about it, and represent the first ever clinical trials of a neural prosthesis controlled by the parietal lobe. Previously, Boris learned about reverse engineering the brain at New York University where he completed his BSc in Neural Science (2008) and developed software for a personal finance startup.

Kris Chaisanguanthum, Ph.D.
Chief Scientific Advisor

Kris (Ph.D. 2008, Particle Physics, Harvard) has a stellar scientific track record and statistical background, publishing on topics ranging from rare decays of exotic subatomic particles to neural computation to the neuroscience of baseball. He earned an AB in Physics from Harvard College in 2001, and among his awards are fellowships from the Sloan foundation, Gatsby foundation and NSF.
