Hi There!

My name is Kiley Kennedy

I research experimental particle physics and am passionate about science outreach and advocacy.

I am a Dicke Postdoctoral Fellow at Princeton University and received my Ph.D. in Physics from Columbia University in 2022.

If you are curious about my research projects, outreach activities, or other interests, please scroll down or check out my CV for more details.

RESEARCH INTERESTS

The Standard Model of particle physics constitutes the most complete and experimentally validated description of particles and their interactions. However, overwhelming evidence suggests the theory is incomplete. The Large Hadron Collider (LHC) at CERN, located outside Geneva, Switzerland, opens an experimental gateway to probe new physics beyond the Standard Model, which could lead to a deeper understanding of the universe. My research centers on analyzing the proton-proton collisions produced by LHC and measured by the CMS Experiment. 

At Princeton, I focus on searching for new physics through specialized triggers, which are algorithms that rapidly (in microseconds to milliseconds) determine which data to save for further processing vs. which to discard. I currently work on two dedicated trigger and analysis efforts -- for so-called long-lived particles (LLPs) and anomaly detection -- that employ unique detector reconstruction techniques and novel machine learning approaches. I am also involved in testing and evaluating silicon sensors for the next major CMS detector upgrade, with installation anticipated in 2026.

As a Ph.D. student at Columbia, I worked with the ATLAS Collaboration, another LHC experiment. There, I focused on electronics R&D for hardware upgrades, led detector operations activities, and analyzed billions of proton-proton collisions. My dissertation focused on a search for a never-before-studied detector signature (a displaced and delayed diphoton vertex) produced by an LLP that may arise in several BSM theories, including supersymmetry.

OUTREACH ACTIVITIES

Scientific advancement doesn't happen in a vacuum. Science outreach programs both spark interest in the next generation, who will shape the future of science, and help policy-makers and funding agencies understand the critical implications of scientific discovery for society. For the past several years, I have been involved with and have helped lead numerous outreach programs and public engagement initiatives in the US and abroad. Looking ahead, my main outreach goals are to encourage students to pursue their interest in science and to advocate for continued high-energy physics funding.
