Education

Ph.D. in Applied Physics, Stanford University, 1996

B.A. in Physics, Reed College, 1989

PUNCH Role

Leads the PUNCH team and is responsible for ensuring programmatic, technical, and scientific success in all aspects of the PUNCH mission.

Professional Background and Supporting Experience

Craig DeForest is Southwest Research Institute’s Program Director for solar astrophysics, and the Vice-Chair of the American Astronomical Society’s Solar Physics Division (AAS/SPD). He holds an adjunct professorship at the University of Colorado.

DeForest has studied the Sun, its corona, and the solar wind for over 30 years. His graduate studies at Stanford University (1989-1995) centered on the Multi-Spectral Solar telescope Array, a sounding rocket that helped pioneer EUV imaging of the solar corona. He was Resident Observer (at NASA/GSFC) for the Michelson Doppler Imager experiment on the SOHO mission from 1995-1999; during this time he explored dynamics of the corona and the limits of solar observing in the faint outer corona. Between 2000-2016, he led several ground and suborbital instrument development efforts including SHAZAM (a novel high-speed magnetograph), DASH (a ground-based demonstration heliospheric imaging observatory), and SSIPP (a balloon-borne miniature solar observatory). From 1999-2016, was Press Officer for the AAS/SPD, after which he stepped down to lead PUNCH.

DeForest is well known for his expertise in solar data analysis and reduction. He developed the analysis tools that enabled the current era of photometric heliospheric imaging, and has exploited them with a series of groundbreaking papers. Major milestones include: (1997) first detection of traveling waves in the solar corona; (2001) imaging of faint polar plumes to the limits of the LASCO field of view; (2009) demonstration that the EUV corona is more spatially variable than previously thought; (2011) first background-subtracted heliospheric images useful for feature photometry; (2012) first complete tracking from Sun to Earth of a single CME, and demonstration of the solar origin of CME plasma at Earth; (2014) sensitive detection of inbound features in the outer solar corona using 2-D velocity filtration; (2015) measurement of solar wind turbulence via comet tail tracking; (2016) detection of the breakup of coronal structure and transition to solar wind flow, 0.2 AU from the Sun; (2017) remote measurement of CME chirality, via 3D polarized imaging; (2018) discovery of very highly structured fine detail in the outer solar corona using deep-field campaign data from STEREO/COR2.

Professional Background

For the past two decades, Madhulika (Lika) has led the development of Heliophysics as an integrated scientific discipline from which fundamental discoveries about our universe provide direct societal benefits. As the Lead for the Living With a Star (LWS) program for 16 years (2001-2016), she made possible the flagship missions (e.g. the Solar Dynamics Observatory, Van Allen Probes, Solar Orbiter Collaboration and Parker Solar Probe) including STEREO that would revolutionize our understanding of how the Sun shapes space weather in the solar system.

Since 2017, she was the driving force at NASA Headquarters and at NASA Ames behind the growth of Frontier Development Laboratory, both in terms of the breadth of problem areas tackled as well as in the number of agency and industry partners (e.g. Google, Nvidia, Intel, Lockheed Martin, Planet). The types of innovative solutions include virtual telescopes, data fusion, edge computing, and autonomy and this approach will have an enduring imprint on the way science and exploration is carried out by future generations. She is presently (2020) a Senior Advisor for New Initiatives at Goddard Space Flight Center, and Program Scientist at HQ, HPD.

PUNCH Role

Lead analysis and interpretation of PUNCH data on solar wind variability, turbulence, and microstructure; analyze shock images.

Experience Relevant to PUNCH

Dr. Viall-Kepko is an expert in time series analysis, image processing, and connecting remote observations to those made in situ in order to understand Sun-Earth interactions. Beginning with the research for her dissertation, “Periodic Solar Wind Density Structures”, she has examined Sun-Earth connections, analyzing in situ magnetospheric and solar wind data and connecting those observations with solar wind structures observed in white light imaging data taken with inner Heliospheric Imager and Outer Coronagraph on STEREO/SECCHI (abbreviation). This research shows how high resolution white light imaging data can help to pin down the origin of the slow solar wind and predict the ‘quiescent’ space weather impacting the Earth even on quiet days.

Supporting Experience

Dr. Viall-Kepko uses her time series and image processing expertise to investigate the properties of coronal heating with imaging data and hydrodynamic simulations. Her community service is extensive, having served on Eduardo Sanchez- Diaz’s dissertation committee, gave 80 interviews for the 2017 total solar eclipse, was a SHINE student representative and a representative for the Outstanding Student Paper Awards given by the American Geophysical Union.
