Dr. Jonathan Richardson
Congratulations to Jonathan Richardson for successfully defending his Ph.D. dissertation on "Experimental Constraints on the Exotic Shearing of Space-Time".

"Jon's thesis represents an important milestone. He's done much of the critical work to make the Holometer experiment a reality. It's the most sensitive instrument ever built to study tiny random jitters of space. In his thesis, he shows that the scale of random shear jitter is more than an order of magnitude less than the Planck length, which was the theoretical expectation. The experiment essentially rules out this effect. He's working with our team now to reconfigure the machine to study the other possibility, a jitter of rotational motion, at similar sensitivity. There is some hope that this effect in the laboratory may connect with the cosmic dark energy problem."

Jonathan has received a Research Fellow position at the University of Michigan.

Congratulations to Dr. Laura Kreidberg!
May 24, 2016
Dr. Laura Kreidberg
Congratulations to Laura Kreidberg for successfully defending her PhD dissertation on "Snapshots of Faraway Places: Intensive Atmosphere Characterization of Extrasolar Planets."

"Laura conducted the most ambitious observational programs ever on the topic of exoplanet atmospheres for her dissertation. She used large investments of Hubble and Spitzer Space Telescope time to measure exoplanet atmospheric compositions, thermal structures, energy budgets, and dynamics to understand planetary origins and physics. The papers resulting from her work are the new benchmarks in the field, and provide a foundation for studying the atmospheres of potentially habitable planets with future facilities."
- Jacob L. Bean, Ph.D. advisor

Starting this summer Laura will be a Junior Fellow of the Society of Fellows at Harvard University and a Fellow of the Institute for Theory and Computation at the Harvard-Smithsonian Center for Astrophysics.

Congratulations to Dr. Alexander (Sasha) Kaurov!
March 29, 2016
Dr. Alexander (Sasha) Kaurov
Congratulations to Alexander (Sasha) Kaurov for successfully defending his PhD dissertation on "Challenges in theoretical modeling of cosmic reionization."

"Dr. Alexander Kaurov's work on studying cosmic reionization - the process of ionization of the bulk of cosmic gas by ultraviolet radiation from the first stars and quasars - was instrumental in combining diverse theoretical concepts into a single, unified paradigm that connects directly with modern state-of-the-art numerical simulations. This breakthrough will have numerous practical applications for the analysis and interpretation of the forthcoming observational data from the future James Webb Space Telescope, Giant Magellan Telescope, and radio observations of the epoch when the first galaxies lit up."

Alexander has received a position at the Institute for Advanced Studies in Princeton, NJ.

Life Long Learning program
March 9, 2016
This spring, graduate students, postdocs, and Professors from KICP and the Department of Astronomy & Astrophysics will present at least 19 lectures to older adults throughout Chicago, as part of the Life Long Learning program associated with Daniel Grin's NSF Astronomy and Astrophysics Postdoctoral Fellowship. Adults past retirement age make up an increasingly large demographic, and continued cognitive/social engagement are crucial for healthy aging. We'll bring basic and cutting-edge content in astrophysics to interested older adults at city senior centers, retirement homes, and public libraries. We are always looking for more presenters to reach wider audiences. To conclude this year's program, we will bring hundreds of older adults to the Adler Planetarium in June free of charge.

Wendy Freedman, John & Marion Sullivan University Professor
Congratulations to University Professor Wendy Freedman for being awarded the Dannie Heineman Prize for Astrophysics for 2016!

Citation: "For her outstanding contributions and leadership role in using optical and infrared space- and ground-based observations of Cepheid stars, together with innovative analysis techniques, to greatly improve the accuracy of the cosmic distance scale and thereby constrain fundamental cosmological parameters."

Erik Shirokoff has received a NSF CAREER award
December 22, 2015
Congratulations to Assistant Professor Erik Shirokoff for being awarded a NSF Faculty Early Career Development (CAREER) Program award for "Developing Antenna-Coupled Kinetic Inductance Detectors to Enable Next Generation CMB Experiments". The team will design, build and demonstrate arrays of Kinetic Inductance Detectors (KIDs). A KID contains a very cold, resistance-free device. That device changes its properties when it "sees" the Cosmic Microwave Background (CMB), the faint signal from the young Universe. Vast arrays of KIDs are needed for the next generation of CMB experiments. The team will also provide laboratory experience for undergraduates from underrepresented minorities and for high school students in the Chicago area.

The CAREER award is presented to junior faculty who exemplify the role of teacher-scholars through outstanding research, excellent education and the integration of education and research within the context of the mission of their organizations.

Prof. Richard Kron is the new Assistant Chair for Academic Affairs
September 24, 2015
Dear Colleagues,

I am very pleased to announce that Prof. Richard Kron will become the new Assistant Chair for Academic Affairs, starting October 1, 2015. Rich will continue to lead the implementation of the new AstroU program for undergraduates as well as oversee the success of the careers of our graduate students. Rich will have the support of Dr. Julia Borst Brazas as our new part-time Academic Affairs Administrator, who will also serve as the Assistant to the Assistant Chair for Academic Affairs. Ms. Laticia Rebeles will continue to work closely with our graduate and undergraduate students, and with Julia and Rich, in her role as the full-time Student Affairs Administrator.

I want to take this opportunity to thank Prof. Michael Gladders who, in addition to his other duties, has provided great leadership as Assistant Chair for Academic Affairs. Mike finished implementing the reorganization of the graduate curriculum and spearheaded the development of the Astro Core sequences in the College. He also effectively shepherded our graduate students into completing their theses efficiently and preparing for a productive postdoctoral career. Please join me in thanking Mike for his service and congratulating Rich as he assumes his new responsibilities.

Congratulations to Dr. Louis Abramson!
July 13, 2015
Congratulations to Louis Abramson for successfully defending his Ph.D. dissertation on "Assessing and Understanding Diversity in Galaxy Star Formation Histories."

"Dr. Louis Abramson is an expert on the observation and phenomenological modeling of galaxy evolution, with a particular focus on the relationship between bulk statistical observables of galaxies, such as the distributions of star-formation-rate and mass over cosmic time, and the star formation histories of galaxies. His work during his Ph.D. has led to several new insights into the relationship between the passive (i.e., bulges) and actively star-forming components of galaxies, and led to a clear understanding that the scatter of galaxies across the so-called 'star forming main-sequence' is a critical observable to consider in further analyses, which he will continue as a postdoc at UCLA."
- Michael D. Gladders, Ph.D. advisor

Louis has received a Postdoctoral Scholar at the UCLA Department of Astronomy and Astrophysics.
