Virginie Papadopoulou, Ph.D
Research Assistant Professor – Divers Alert Network Scholar
Virginie received her PhD in Bioengineering from Imperial College London, UK, in 2016, after completing a Master’s degree in Physics in the same university in 2011. Her PhD thesis focused on bubble formation, growth and circulation dynamics in vivo from hyperbaric decompression, relevant to scuba divers and astronauts to prevent decompression sickness. Concurrently as an EU Marie Curie fellow (2012-2014) and COST MP1106 member (2011-2014), she spent time in Belgium working on hyperbaric physiology and in Greece on hyperbaric bubble growth instrumentation. From January 2015 to March 2016 she worked as a postdoc under the supervision of Dr Tang at Imperial College London on 3D ultrasound contrast enhanced flow reconstruction from lab prototype to first human application. She joined the Dayton Lab as a postdoc in May 2016, where her main research focuses on tumor oxygen microbubble therapy combinations and nanodroplet acoustic vaporization.

Marjan Mehrab Mohseni, MS
Marjan Mehrab-Mohseni received a BS in Applied Chemistry from Tehran University, Iran, an MSc in Molecular Cell Biology from Uppsala University, Sweden in 2008. Marjan started her research working on the molecular pathogenesis of liver disease. During her master thesis at Karolinska Institute, she worked on cancer epigenetics and showed that human cytomegalovirus infection alters global DNA methylation capacity. Following immigration to United States, Marjan worked on the molecular pathogenesis of HCV at Carolinas Medical Center where she showed that Legaoln-Sil can down-regulate HCV in vitro through altering expression of tight junction components. Marjan research has so far led to more than 10 publications and 200 citations in prestigious journals. Marjan currently doing her research at UNC under supervision of Dr. Paul Dayton from BME and Dr. Samantha Pattendon from UNC School of pharmacy. In here recent work, Marjan has developed a novel cavitation-enhancement nanodroplet reagent which can decrease the time and acoustic energy required for gDNA fragmentation. gDNA is one the most sensitive, time- consuming steps of epigenetic assays like, CHIP, Fair and next-generation sequencing. Marjan has also showed that cavitation enhancement increases the efficiency and consistency of chromatin fragmentation from fixed cells for downstream quantitative applications.
Jinwook Kim, Ph.D
Jinwook received his B.S. and M. S. degrees in Mechanical Engineering from Kyungpook National University in 2010 and 2012, respectively, for his work in piezocomposite transducers for underwater ultrasound. He received a Ph.D. in Mechanical Engineering from North Carolina State University for his work in miniaturized ultrasound transducers for the acoustic excitation of microbubbles and microgels. He joined Dayton lab in September 2017 as a post-doctoral researcher. His current works include intravascular acoustic angiography, intravascular sonothrombolysis, and laser-generated ultrasound transducers for nanodroplet/microbubble-mediated ultrasound therapies. In collaboration with the Jiang lab (NCSU), he works on development of novel imaging and therapeutic transducers.
