2016 SHINE Workshop. L to R: L. Woolsey, S. Van Kooten, A. Schiff, S. Cranmer, C. Gilbert

Current Students

  • I've been working with CU APS graduate student Avery Schiff since summer 2015. We've submitted a paper on coronal heating in large quiescent loops observed by EUV tomography, and we're now working on ideas concerning how electrons conduct heat in the solar wind.

  • I've been working with CU APS graduate student Sam Van Kooten since early spring 2016, on the topic of how the motions of magnetic bright points in the Sun's atmosphere contribute to waves and plasma heating higher up in the corona.

  • I've been working with CU APS graduate student Chris "Gilly" Gilbert since summer 2016, on the topic of how density fluctuations in the solar corona affect large-scale 3D models of turbulence and solar wind acceleration.

  • I've been working with CU APS graduate student Momchil "Momo" Molnar since fall 2016, on the topic of waves in the chromosphere and corona, and with observations from ALMA and the Dunn Solar Telescope.

  • I've been working with CU APS graduate student Aylecia Lattimer since summer 2019, on a project involving the atomic physics of radiatively driven flows in a wide range of astrophysical environments.

Past Students

  • From 2011 to 2016, I advised Harvard University graduate student Lauren Woolsey, who completed her dissertation work on models of the acceleration of the solar wind. Lauren is now an Assistant Professor at Grand Rapids Community College.

  • In Fall 2015, I supervised a research project for CU senior undergraduate student Jacob Jost on the topic of the line-of-sight effect in off-limb observations of MHD turbulence in the solar corona.

  • In Spring and Summer 2018, I supervised research projects for CU undergraduate student Shaniya Jarrett on: (1) plasma fluctuations in the solar wind at 1 AU, and (2) atomic physics of spectral lines that drive winds of massive stars.

Academic Genealogy

The academic world is one of the few remaining professions which still operates (for good or ill!) on the time-honored system of apprentices and mentors. Is it possible to see traces of an advisor, or an advisor's advisor, or an advisor's advisor's advisor... in a scientist's work? In any case, there are various web pages that attempt to gather together this kind of genealogical information, but it hasn't quite taken hold in astrophysics as much as it has in, say, mathematics. Thus, I'm not sure if this is of interest to anyone besides me...

  • Steven R. Cranmer recieved his Ph.D. in 1996 from the University of Delaware. Thesis title: "Dynamical Models of Winds from Rotating Hot Stars" (lots more info about it here).   His advisor was...

  • Stanley P. Owocki (web page), who received his Ph.D. in 1982 from the University of Colorado Boulder. Thesis title: "The Ionization State of the Solar Wind."   His advisor was...

  • Thomas E. Holzer, who received his Ph.D. in 1970 from the University of California, San Diego. Thesis title: "Stellar Winds and Related Flows."   His advisor was...

  • Well, here it starts to get complicated. Tom Holzer's official university advisor was UCSD's Peter M. Banks. Holzer and Banks wrote some very highly cited papers together. However, the story as I heard it was that Banks was mainly an "on-paper" advisor, and that Holzer's primary mentor for his thesis was really...

  • Sir W. Ian Axford (wikipedia), who received his Ph.D. in 1959 from the University of Manchester, UK. Thesis title: "Some Problems in Fluid Dynamics."   His advisor was...

  • Sir M. James Lighthill (wikipedia), who graduated from Trinity College, Cambridge in 1943, and was elected a fellow of Trinity College in 1945. I still haven't figured out whether or not he had a formal advisor in the modern sense. However, there is a fun way to trace his "lineage" even further back in time. In 1969, Lighthill became the 16th Lucasian Professor of Mathematics at Cambridge. His predecessors in the Lucasian "Chair" included Paul Dirac, George Stokes, Charles Babbage, George Airy, and...

  • Sir Isaac Newton!

Erdős Number

Mathematicians enjoy measuring their "collaborative distance" to the famous Paul Erdős, and enough astronomers have collaborated with mathematicians that it's possible to compute our Erdős numbers, too.

As best as I can tell, my Erdős number is no larger than 5, with the shortest chain of coauthorships being:

S. R. Cranmer (5) → George B. Field (4) → John N. Bahcall (3) → Freeman J. Dyson (2) → Dean Robert Hickerson (1) → Paul Erdős
