Dr. Jonathan Hernandez is a surgical oncologist/HPB surgeon, chief of the surgical oncology section (Surgical Oncology Program/NCI/NIH), Associate Professor of Surgery (Uniformed Services University of the Health Sciences), and Clinical Professor of Surgery (George Washington University). He specializes in the treatment of liver metastases from colorectal cancer and neuroendocrine tumors, primary biliary tract cancers, as well as other complex abdominal tumors including recurrent and metastatic adrenocortical carcinoma. Dr. Hernandez’s research efforts focus on unveiling novel therapeutic vulnerabilities for these cancers, which enlist the use of locoregional drug delivery techniques. The Hernandez lab has developed and now implements ex-vivo human tumor systems using tissue directly from the operating room to provide an avenue of translationally relevant interrogation.
