Sreeja Sridharan

Sreepradha Sridharan (Undergraduate Intern)  

Sreeja is an undergraduate student from Apex, NC currently majoring in Biology with a concentration in Integrative Physiology and Neurobiology. She joined the lab in May 2015 and her research currently focuses on an NIH-funded project to determine the potential of carbon nanotubes to cause the neoplastic transformation of pleural mesothelial cells in vitro to predict risk of mesothelioma. Sreeja will start her graduate program in the fall of 2018 at MD Anderson Cancer Center in Houston, TX.

Gina Hilton (Graduate Student):

Gina, originally from Baltimore MD, joined the Toxicology Program as a PhD student in 2013 in the laboratory of Dr. Michael Bereman. Her PhD work bridged the Bereman and Bonner labs and used a proteomic approach to better understand in-vitro nanomaterial induced cytotoxicity. Gina graduated with her PhD in Toxicology in 2017 and now works as a Toxicologist at PETA International Science Consortium, Ltd.

Laura Finerty

Laura Finerty

Laura worked in the Bonner Lab in 2016 as undergraduate intern during her senior year at NCSU while working on her BS in Biological Sciences.
