Edwin Chang, PhD

I previously worked at Geron Corporation (Menlo Park, California) where I studied the mechanism of cellular immortalization and cellular aging with the goal to develop new therapies against cancer. I joined Stanford University in 2002 and the Molecular Imaging Program at Stanford (MIPS) in 2009, where I explored the applicability of various modalities (PET, BLI, CT, MRI, US) for many projects related to cancer under the leadership of Sanjiv Sam Gambhir. Most recently, I joined the Daldrup-Link lab where I continue to investigate new cell therapies for the treatment of glioblastoma with multi-modality imaging techniques. Since, July 2020, I have been appointed Director of the Canary Core Preclinical Imaging Facility at the Canary Center of Stanford, Stanford University.

Michael Barrow, PhD

My background is Computer Science (PhD) and Electrical Engineering (MSc). I am interested in the application of AI/ML in oncology diagnosis and treatment problems. In particular I am exploring questions regarding how AI can boost clinical workflow productivity with decision making aids.

My projects seek to build models of rare disease from complex structural and functional data modalities that can be applied to downstream clinical tasks. My goal is that such models will reduce the cognitive load and save the time of a clinician user.

Ramesh Duwa, PhD

I am a postdoctoral research fellow in the Daldrup-Link lab at the department of Radiology (Stanford University). I received my PhD in 2023 in molecular imaging and targeted therapeutics from Keimyung University of South Korea. My research interest focuses on the development of theranostics nanoparticle and nanoparticle-drug conjugation (NDC) for targeted delivery of drug and/or diagnostic agents to the cancer miscroenvironment, using molecular imaging for in vivo drug tracking. I am currently focusing on development of theranostic nanoparticles for image-guided drug delivery to brain cancer. Beside this, I am collaborating on molecular imaging of CAR-T cell-based immunotherapy. I am dedicated to collaborating with like-minded scientists and contributing to advancements in this exciting field.

Raheleh Roudi, PhD

I am a research scientist in the Department of Radiology at Stanford University. I worked as an Assistant Professor at the Iran University of Medical Sciences, Iran from 2015 to 2019, before coming to the United States. During this time, I worked on several projects which have led to successful collaborations with the Karolinska Institute; Charite University Hospital in Berlin; Oslo University Hospital; National University of Singapore; Shanghai University of Traditional Chinese Medicine and University of Brescia, among other internationally recognized institutions. I was a visiting scientist at the University of Texas at San Antonio and then appointed as a postdoctoral research associate at the University of Minnesota for one year, before joining Stanford University in 2022. At Stanford, I investigate novel immunotherapies for osteosarcomas with ferumoxytol-MRI and PET/MRI. My research interest focuses on molecular imaging, molecular oncology and immunotherapies of solid tumors. I published more than 40 peer reviewed scientific manuscripts thus far.

Giovanni Marco Saladino, PhD

I am a Postdoctoral Scholar in the Department of Radiology at Stanford University. I graduated in Engineering Physics with a BSc at Politecnico di Milano (Italy) and an MSc at KTH Royal Institute of Technology (Sweden). In 2024, I obtained my PhD in Biological and Biomedical Physics from the Department of Applied Physics at KTH Royal Institute of Technology.

My research interests lie at the intersection of molecular imaging, nanomedicine, and nanomaterials. Specifically, I focus on developing novel contrast agents and exploring advanced imaging techniques. During my PhD studies, I designed hybrid multimodal contrast agents for complementary imaging using X-ray fluorescence computed tomography, magnetic resonance imaging, and optical fluorescence imaging. I am currently involved in investigating theranostic applications of nanomaterials, which hold great promise for personalized medicine and targeted therapies.

Jie Wang, PhD

I am driven by the potential of magnetic nanotechnology to revolutionize healthcare. This includes the investigation of nanoparticles for medical imaging, such as magnetic resonance imaging (MRI) and magnetic particle imaging (MPI) as well as the use of magnetic nanoparticles for theranostic treatments and magnetic hyperthermia (MNFH). My PhD research on MRI-guided magnetic hyperthermia for cancer theranostics sparked my passion for developing minimally invasive treatment options. Currently, I explore brain cancer theranostics using tumor-enzyme activatable nanoparticles, investigating their interaction with the tumor microenvironment through multi-modal imaging. This research aligns with my vision to translate fundamental scientific discoveries into clinically relevant tools that improve patient outcomes.

Emily Rodriguez

Emily is an undergraduate senior at San Diego State University studying cellular and molecular biology. She participated in the Stanford Summer Research Program in Dr. Daldrup-Link’s lab. She explored iron metabolism and macrophage activation under the guidance of Dr. Raheleh Roudi. Fueled by passion, after graduation, she plans to enroll in a cancer biology PhD program to investigate potential signaling pathways that can be targeted to develop novel therapeutics. Once she completes her PhD, she plans to become a principal scientist and mentor students, encouraging the younger generation of minority scientists to pursue their passions.
