My research interests lie in stellar evolution and their destruction mechanisms. Currently, I am studying the chemistry and heating of planetary nebulae, using radio line emission observations to understand the radiatively-driven processes occurring in the extended molecular envelope. I am also interested in how this relates to protoplanetary disks and other cold astrophysical environments.

My research interests span a wide range of topics in cosmology with focuses on significant epochs in the universe's formation. I am currently working in the Center for Detectors with Dr. Zemcov on the Tomographic Ionized-carbon Mapping Experiment (TIME), in collaboration with Caltech. I am responsible for creating the software necessary to collect data from and control TIME, which will allow us to study the epoch of peak star formation and the epoch of reionization.

My topics of research include Data Analysis, Gravitational Wave Parameter Estimation (as a member of the LIGO Scientific Collaboration), and the phenomenological study of cosmology through comparison of different models to the likelihood of individual Gravitational Wave detections. I recently earned my masters degree in the same program, and participated in the La Serena School for Data Science in Chile.

Brendan Drachler

Brendan Drachler is a PhD student working at the Center for Computational Relativity and Gravitation (CCRG) under Prof. Manuela Campanelli. He is primarily interested in magnetohydrodynamics simulations of supermassive binary black holes and their accretion disks as well as using the simulations as tools to understand the underlying physics that occurs near these massive objects. He is also participating in a large collaborative effort poised to simulate  accretion processes in binary neutron star coalescences from prior to merger through to the formation of disks and/or collapse of the merged remnant, the production of jets, and launching of outflows.

I am interested in computational MHD (Magnetohydrodynamics). Specifically, I look at the various ways plasma is confined inertially, magnetically, and gravitationally. I am currently working on the last, modeling an accretion disk formed by a tidally disrupted companion around a white dwarf. I am doing so with a code developed by the University of Rochester called AstroBear.

I am working with Dr. Joshua Faber on developing and expanding the neutron star initial data code called Lorene. The aim of the project is to produce more initial data with different equations of state and mass ratios. I also work on producing dynamical runs of neutron star mergers using the Einstein Toolkit.

Jacob Lange 

My research is on gravitational wave parameter estimation for binary black holes by comparing numerical solutions of Einstein's equation (i.e. Numerical Relativity simulations) directly to the data. By doing this, we avoid ad hoc approximations used in analytic and semi-analytic models and get the most information possible out of the signal as possible. Our method work for unequal mass and generic spin including higher modes.

 My research interests lie in experimental cosmology, specifically on the detection of dark matter particle candidates. I am currently working on the design and construction of a cryostat for a far-IR FTS. This will eventually be used on a sounding rocket for RAxDEx, which searches for light from the two-photon decay of axions.

My work focuses on understanding the extragalactic background light (EBL). The infrared EBL probes the history and origin of stellar emission, which allow us to constrain models of star and galaxy formation. I am working on the fabrication and integration of the Cosmic Infrared Background ExpeRiment 2 (CIBER-2), which uses a small telescope launched on a sounding rocket, to characterize the infrared EBL via its fluctuations.

I am searching archival data bases to find new targets for reverberation mapping of active galactic nuclei (AGN), using optical and infrared data. We can use the time delay between variations in the optical and the infrared to measure the size of the dusty torus around the AGN to better understand the torus structure and characteristics.

My primary interests lie in the fields of computational astrophysics with a focus on mathematical modeling, magnetic fields, and general relativity, particularly in the case of neutron stars. I am currently using neural networks for GW data analysis with the goal of eventually approximating kilonova light curves for the purpose of binary neutron star post-merger parameter estimation.

I am working on characterizing the morphologies of very high redshift galaxies in order to identify galaxy mergers, which are one of the driving forces of galaxy evolution. I am using simulated James Webb Space Telescope (JWST) images to develop a new and reliable method for identifying mergers via quantitative measurements and visual classification as a function of image depth, filter and perspective in preparation for real images from JWST. JWST is the successor to the Hubble Space Telescope (HST) and will probe higher redshifts than HST with higher resolution and quality.

I am interested in how the interaction of galaxies affects galaxy properties over the evolution of the Universe. Specifically, I am conducting a statistical analysis of multiwavelength  CANDELS Survey data to estimate the effects of these interactions on Star Formation and AGN Activity of galaxies.I have been also working on spectroscopic observations of galaxies obtained using the DEIMOS instrument on the Keck telescope in Hawaii to estimate the redshifts of potentially interacting high redshift galaxies.

My research interests are in a multi-wavelength observational approach to understanding galaxy formation and evolution over cosmic time. Currently I am using this approach to investigate the kinematics of luminous starburst galaxies at high redshift, in an effort to determine the role of mergers in galaxy evolution. I continue to consider my previous work of the dynamic and chemical nature of circum-galactic gas as it may relate to my current analyses. I am also passionate about science outreach, particularly to under represented groups.

I am using observations of gravitational waves from coalescing binaries to characterize how frequently different binaries form over cosmic time. This will in turn be used to test stellar evolution models, and constrain the overall stellar population. Other research interests include astrostatistics, time series, transient searches, and time domain astronomy in general.
