ACR Morin fellowship

Feeling honored and super excited to be selected as one of the two national ACR Morin Fellows in Medical Physics!

General poster for the 2026 Joint AAPM | COMP Annual Meeting & Exhibition in Vancouver, BC, July 19 - 22, 2026

My abstract was accepted for a general poster discussion at this year's joint AAPM|COMP Annual Meeting in Vancouver, BC.

General Poster Discussions (GPD) include a select group of high-scoring posters identified by the Program Directors as being of special interest to attendees across the scientific, professional, and education programs.

GPD sessions provide structured time for questions and in-depth discussion with authors.
These posters are featured in the Poster Lounge and highlighted in the program as a point of focus.
They can also be viewed throughout the week in the Exhibit Hall and online through the meeting app and website.

New paper in smoking addiction is now out in Brain and Behavior

This project was especially meaningful to me because it let me bring a lot of the skills I developed during my PhD into a new area of neuroimaging, and I learned a great deal along the way. In this study, we found reduced whole-brain network segregation in chronic smokers, along with lower tNAA in the dorsal anterior cingulate cortex, suggesting subtle but systematic alterations in executive-control and reward-related systems.

Selected as an Associate of the AAPM ICAMP 2026-2027 cohort

CT project in photon-counting detector published in Medical Physics

Excited to share my first publication in Medical Physics!

After focusing on MRI applications in neuroimaging and toxicology in the past, this CT study represents my first publication within the field of medical physics (and my first as a resident).

My latest project on brain structural and MRS changes in smokers was accepted as an oral presentation at AAPM 2026

See you all in DC!

Had a great time at ISMRM in Hawai‘i!

Just got back from ISMRM 2025 in Honolulu — what an experience! This was my first time attending not as a PhD student, but as a medical physics fellow, and the shift felt both surreal and exciting. I had the chance to present my research on neuroimaging markers of smoking addiction, and it sparked some great conversations with people working across clinical and research spaces. Grateful for the feedback, the connections, and the beautiful backdrop of Hawai‘i.
