I am an NSF Graduate Research Fellow studying Physics at Stanford University. I graduated from the University of Chicago with a B.A. in Physics in 2020.

My notes for general onboarding for scientific computing can be found here.

I've collected some fun resources for statistics here.

# Research

My research broadly involes using large cosmic surveys to study the properties and composition of the Universe. I search for ultra-faint satellites of the Milky Way and use their properties to constrain the microphysical properties of dark matter. I also study the spatial correlations of point spread functions (PSF) to understand systematic uncertainties in cosmological measurements. I am an active member of LSST DESC, DELVE, and DES.

Present

Burchat Group
2021–present
Kavli Institute for Particle Astrophysics and Cosmology
Stanford University

I am currently working with Professor Pat Burchat to measure bias introduced in the cosmological 2-point correlation function due to PSF effects. My current project involves using Gaussian processes to solve for the astrometric solution in simulated images with realistic atmospheric realizations.

Past

LSST CAMERA Integration and Testing Group
2021
SLAC National Accelerator Laboratory

I worked with Professor Aaron Roodman to characterize LSST CCD sensors for integration and testing.

Galaxy Formation and Cosmology Group
2020
Kavli Institute for Particle Astrophysics and Cosmology
Stanford University

I worked with Professor Risa Wechsler and Ethan O. Nadler with the Galaxy Formation and Cosmology group at Stanford University. I am leading an analysis using N-body zoom-in simulations for a decaying dark matter cosmology to determine a subhalo mass function for decaying dark matter and to ultimately use the Milky Way satellite census to constrain the decay lifetime of dark matter.

Survey Science
2017–2020
Kavli Institute for Cosmological Physics
University of Chicago

I worked with Professor Alex Drlica-Wagner as part of the Survey Science group at UChicago on searching for dwarf galaxies in data from DES, MagLiteS, BLISS and DELVE. In collaboration with Professor Drlica-Wagner and William Cerny, I led the discovery and characterization of a new ultra-faint dwarf galaxy, Centaurus I, and two new faint star clusters, BLISS 1 and DELVE 1. I contributed to the characterization of the observational selection function for Milky Way satellites in DES Y3 and Pan-STARRS DR1 as well as using these results to inform constraints on the galaxy–halo connection. I have observed with DECam at the 4m Blanco telescope in-person and remotely for MagLiteS and DELVE.

ATLAS Experiment
2018–2020
Enrico Fermi Institute
University of Chicago

I worked with Professor Mark Oreglia on searching for invisible decays of the Higgs boson in ATLAS data. I developed a framework for training a neural network on simulated ATLAS data that is now being implemented to increase our sensitivity for detecting exotic decays of the Higgs boson. I repaired 3in1 bigain cards and mainboards being used in the ATLAS Tile Calorimeter as well as helped test and validate upgraded electronics for the ATLAS detector's hadronic calorimeter in anticipation of the High-Luminosity LHC. I contributed code for analyzing radiation simulations to understand the required electronics tolerances and for analyzing the statistical impacts of a risk register to cost and scheduling for the ATLAS experiment.

TASIS England Physics Research Group
2015–2016
TASIS England

I worked with Dr. Scott C. Dudley on exploring physics using accelerometers and other sensors found in smartphones and similar devices. We also explored using the iOLab system to make novel measurements in the classroom, including mapping the flow of current through a copper sheet.

# Outreach

As I begin my graduate studies, I am looking to explore ways I can engage in public outreach, broaden accessibility to science, and advocate for and advance systemic change towards equity and inclusivity in physics.

Present

Past

Space Explorers
2018–2019
Kavli Institute for Cosmological Physics
University of Chicago

I volunteered as an instructor and program developer for the Space Explorers program with the Kavli Institute for Cosmological Physics at UChicago for two years during my undergraduate studies. This program focuses on providing hands-on experience with physics for under-represented minorities in high school. As part of the Space Explorers program, I developed hands-on projects for the students that focused on growing their familiarity and confidence in STEM. I also volunteered during the Summer and Winter Institutes at the University of Chicago and Fermilab, helping the students realize and present their projects.

@rtifice
2017
Artifice NFP

I volunteered as an instructor at @rtifice for part of my first and second years at UChicago, teaching computer science and technology concepts to elementary school students in the South Side Chicago area.

# About Me

I'm Sid (he/him/his). I come from a family of artists and designers. I grew up in the small town of Neenah, Wisconsin; I lived outside of London for several years, completed my undergraduate studies in Chicago, and am now at Stanford for my graduate studies.
