CCAPP would like to congratulate the following postdocs and students who have already accomplished so much and are moving on to do great things in their next positions.  We will miss you!

Kaili Cao — His research focuses on developing advanced analysis infrastructure and computational methods for next-generation astronomical surveys to better understand stellar evolution and the large-scale structure of the Universe. This work ensures that the astronomical community is equipped with the robust analytical tools and precise algorithms necessary to extract accurate, meaningful insights from the vast datasets generated by upcoming surveys. At CCAPP, Kaili's key accomplishments were testing stellar theory through APOKASC-3 data, developing and optimizing the image reconstruction algorithms required for the Roman Space Telescope’s weak gravitational lensing cosmology program, and conducting Fisher forecasts for its cosmological parameter constraints. 

Raquel Fores Toribio — She studies variable phenomena, particularly extragalactic microlensing, stellar transients, and supernovae. Time-domain astronomy allows us to track real-time changes in the universe, which is extremely useful for characterizing the evolution and nature of very different phenomena. At CCAPP, Raquel’s key accomplishments were successfully expanding her areas of expertise by pivoting to a different research field and acquiring skills that are broadly applicable in astronomy.

Emily Koivu — She uses analytic and computational tools to broadly study the early universe and dark matter. Studying the history of the early universe and the dark matter that holds our galaxies together informs the conditions for our own existence here on Earth and in the Milky Way. At CCAPP, Emily's key accomplishments were developing the first numerical study of corrections to Hawking radiation from primordial black holes, assessing the impact of these modifications on cosmology, and helping cultivate an environment where people can thrive.

Katherine Laliotis — She uses systematics in observational probes of cosmology for Roman and Rubin telescopes. This enables high-precision measurements of the cosmos. At CCAPP, Katherine's key accomplishments were developing foundations for image processing infrastructure of the Roman Space Telescope High Latitude Imaging Survey team, and contributions to commissioning the Rubin Observatory LSST Camera. 

William Luszczak — He explores how astroparticle messengers can be used to increase our understanding of the universe on both astronomical (AGN) and human (Earth's atmosphere) scales. This research uniquely connects fundamental research in astroparticle physics to human-scale phenomena that affect every day life (severe weather). At CCAPP, Will's key accomplishments were the first measurement of atmospheric muons near the base of a forming tornado, as well as, leading the latest IceCube point source public data release, developing PUEO simulations, and improving neutrino flux measurements for TXS 0506+056. 

Charlie Mace — He uses numerical simulations of galaxy evolution to study the nature of dark matter, with an emphasis on testable predictions of self-interacting dark matter in gravitationally lensed systems. The nature of dark matter is one of the biggest mysteries in modern astrophysics, one which is deeply connected to the history and contents of our Universe. At CCAPP, Charlie’s key accomplishments were rigorous tests of numerical simulation accuracy, calibration of gravothermal catastrophe models in self-interacting dark matter halos, and the implementation of these models into substructure gravitational lensing analysis pipelines.

Obada Nairat — He studies neutrinos and develops methods to improve the sensitivity of large underground detectors, enabling more precise measurements of fundamental particle properties and astrophysical processes. More precise neutrino measurements can reveal new physics beyond the Standard Model and deepen our understanding of the Sun, stars, and the fundamental laws of the universe. At CCAPP, Obada's key accomplishments were developing novel background reduction techniques for large neutrino detectors, demonstrating how these methods can substantially improve the sensitivity of future solar neutrino measurements in Super-Kamiokande and Jiangmen Underground Neutrino Observatory.

Alan Salcedo Gomez — He searches for neutrinos of ultra high energies from astrophysical sources. UHE neutrino's energies are not yet achievable by human-made accelerators, so they are the unique probes of physics at these unattainable energies. UHE neutrinos are also the only remaining handle to find the sources of ultra-high energy cosmic rays which are protons or nuclei from outer space of the highest energies ever observed. At CCAPP, Alan's key accomplishments were producing the first ever search for ultra-high energy neutrinos using a full in-ice array of antennas looking for their signals and setting the world's best constraints on such searches in the field of radio detectors. 

Wynne Turner — She develops new analysis techniques to extract more cosmological information from observations of the Lyman-alpha forest, the absorption patterns imprinted by intergalactic hydrogen. By extracting more information from astronomical observations, this research enables more precise tests of our understanding of the universe and its evolution. At CCAPP, Wynne's key accomplishments were developing novel machine learning and statistical techniques that improve cosmological measurements from the Lyman-alpha forest and applying them to data from the DESI survey. 

Erik Zaborowski — He studies cosmology from galaxies and the cosmic microwave background. There are big things that we still don't understand about the pieces of the Universe! At CCAPP, Erik's key accomplishments were weighing in on the Hubble tension with the most precise sound-horizon-free (early-time) H0 constraint, and contributing to DESI's landmark cosmology results.
