My research is focused on mapping GBM tumor heterogeneity with multimodal and multiparametric PET-MR imaging and spatially-registered core biopsy advised by Dr. Jason Parker. I love animals and have a few of them at home. What I love more than animals are people! The term social butterfly is pretty accurate about me. And curing cancer is my bright and shining passion.


Alexis WebbSecretary: Alexis Webb
PhD student, Medical Physics, Radiation Therapy
MS Medical Physics, University of Arizona, 2019
BS Physics, University of Delaware, 2017

I am working on a project in Dr. Linda Nie’s lab that uses synchrotron x-ray fluorescence to detect and quantify lead and other metals in brain tissue to study their role in Alzheimer’s Disease. When I am not working, I like to run, spend time with friends and family, travel, and try new recipes!



Treasurer, Humberto MonsivaisTreasurer: Humberto Monsivais
MSc. Student, Medical Physics, Diagnostic Imaging
BS Physics, Stephen F. Austin State University, 2015

I am advised by Dr. Ulrike Dydak. My current research is focused on GABA and GSH editing in Magnetic Resonance Spectroscopy and quantitative MRI in studies on manganese neurotoxicity, postpartum depression, and addiction. In my free time, I enjoy going out to visit new places (restaurants, parks, etc), running, and playing video games with my friends.



Yiu-Hsin ChangSenator: Yiu-Hsin Chang
PhD student, Medical Physics, Radiation Therapy
BS Radiology Sciences, National Yang-Ming University, Taiwan, 2019

I’m from Taiwan. I am working with Dr. Keith Stantz to investigate immune response induced by radiation and to examine effectiveness of high- and low- LET on IFN-beta production. I love playing volleyball, watching Netflix and listening to the music when I’m free. I’m also a foodie, and I love exploring good restaurants around West Lafayette/Lafayette.




ShannahanAdvisor: Dr. Jonathan Shannahan
Assistant Professor of Toxicology and Health Sciences

Dr. Shannahan’s research focuses on the examination of mechanisms of susceptibility to environmental and occupational exposures. This includes the assessment of cardiopulmonary and immune toxicity in prominent subpopulations utilizing a variety of cell culture and animal models. I enjoy spending time with my children, sports, and traveling.
