Following this, he was awarded a prestigious fellowship from the Bodossaki Foundation, in Greece before relocating to the United States in 2013. He joined Dr. Koumenis's lab at the Department of Radiation Oncology at the University of Pennsylvania, where he completed his postdoctoral training in Radiation and Tumor Biology.

Yiannis loves traveling, sailing, and watching movies, with a particular interest in WWII films.

Kyle Kim
Research Assistant

Kyle Kim is a research specialist who recently graduated from Penn in 2023 majoring in biochemistry and chemistry. He is currently planning on pursuing a MD/PhD. In the lab, he is focused on investigating the regenerative capacity of intestinal crypts using a novel mouse model of focal radiotherapy. Additionally, he is interested in delineating the role of ATF4 in a preclinical model of radiation-induced myocardial fibrosis. Outside of the lab, he spends his time working out, playing volleyball, and exploring the city!

Ioannis Paraskevaidis, MSc
PhD student

Ioannis (Yiannis) Paraskevaidis earned his bachelor's degree in Biology from Aristotle University of Thessaloniki, Greece. Yiannis continued his academic journey by completing a master's in Biomedical Research at The Cyprus Institute of Neurology and Genetics, where he actively contributed to research in epigenetic therapy for melanoma. Currently, he has joined the Verginadis Lab as a graduate student. His research focuses on utilizing radiation for pancreatic tumor therapeutics and unraveling the complex mechanisms associated with pancreatic radioresistance. Outside of the lab, Yiannis enjoys playing tennis, hiking, and exploring the world through travel.

Shria Kavaturu
Undergraduate student

Shria is an undergraduate at the University of Pennsylvania studying biochemistry on the pre-medicine track. After graduation, she hopes to attend medical school and pursue a career as a clinician and researcher. In the past she conducted research to understand the role of ORAI1 in T-Cell activation and the ability of specific flow cytometers to sort and analyze potentially cancerous extracellular vesicles. She recently joined the Verginadis lab with the goal of gaining expertise in various molecular techniques and in vivo procedures. Outside of the lab, Shria volunteers at the Ronald McDonald House and is a part of Community School Student Partnerships where she volunteers at Comegys Elementary in West Philadelphia.

Samuel Chung
Visiting SUPERS student

Sam is a visiting SUPERS student and is currently studying chemistry (as a pre-med) at SUNY Binghamton, with a focus in biological chemistry. At his lab at Binghamton, his research focuses on improving linker technology in Antibody-Drug Conjugates and validation with biological assays. Currently, Sam is investigating the role of STAT3 on pancreatic tumor radiosensitization. Outside the lab, Sam loves going to the gym, playing the cello, and scrolling Instagram/TikTok!

Yuyu Wang
MD student

Yuyu is a MD student at the University of Groningen, the Netherlands. She also obtained her bachelor’s degree in microbiology and immunology at the University of British Columbia, Canada and master’s degree in biomedicine at Karolinska Institutet, Sweden. She previously participated in translational cancer research focusing on neuro-immunology, tumor microenvironment and radiotherapy response in brain tumors. She recently joined the Verginadis Lab to investigate gene signatures linked to chemoradiotherapy resistance in pancreatic ductal adenocarcinoma. Outside of the lab, she enjoys jogging, cooking and traveling!
