Mahsa ServatiPresident: Mahsa Servati
PhD student, Medical Physics, Diagnostic Imaging
MSc. Medical Physics, Purdue University, 2020
MSc. Physics, Texas Tech University, 2018
BSc. Physics, Sharif University, 2015

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.


Vice-President: Humberto Monsivais
Ph.D. Student, Medical Physics, Diagnostic Imaging
MSc. Medical Physics, Purdue University, 2021
BS Physics, Stephen F. Austin State University, 2015


I am advised by Dr. Ulrike Dydak. My current research is focused on brain quantitative multi-parameter mapping MRI in studies on manganese neurotoxicity and addiction. This also includes Magnetic Resonance Spectroscopy (MRS) for the noninvasive in-vivo assessment of metabolite and neurotransmitter concentrations. In my free time, I enjoy going out to visit new places (restaurants, parks, etc.), running, and playing video games with my friends.


Alexis WebbSenator: 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!



Yiu-Hsin ChangTreasurer: 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.




Secretary: Brian Bozymski
Ph.D. Student, Medical Physics, Radiation Therapy
BS Physics, BS Mathematics, Indiana University Bloomington 2020

I am advised by Dr. Dydak. My research involves using Magnetic Resonance Spectroscopy (MRS) to explore the use of 31P metabolites (ATP, etc.) as non-invasive, diagnostic markers for liver disease. Outside of work, I enjoy running, playing videogames, observing my cat's antics, and generally living life with my wife. 



Social Chair: Sydney Stradtman
Ph.D. Student, Toxicology
BS Biomolecular Sciences, Clarkson University, 2020

My research focuses on finding specific molecular targets of atrazine during developmental stages to elucidate a mechanism of toxicity with low dose, environmentally relevant exposures using the zebrafish model. Outside of the lab, I love to hike, travel, and cook!





Communicator: Saeed Alqahtani
Ph.D. Candidate, Toxicology (Mentor: Dr. Shannahan)
MSc. Toxicology, Colorado State University, 2018

Saeed is interested in investigating toxicity associated with environmental and occupational exposures in susceptible subpopulations. Saeed’s research focuses on understanding how individuals with underlying diseases such as metabolic syndrome (MetS) respond to inhalation exposure of engineered nanomaterials. When I am not working, I like to play soccer, volleyball, and taekwondo!



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.
