John Swain

John Swain
Research Associate

Education: Education: B.S. in biology, University of Southern California

Michael Parappilly

Michael Parappilly
Research Assistant 2

Education: B.S. in human physiology, University of Oregon

Scientific interests: I am interested in understanding tumor behavior at the molecular and cellular level, and how a novel population of circulating cells affects disease progression and metastasis. 

Matthew Dietz

Matthew Dietz, D.O., M.S.Ed.
Pediatric Hematology and Oncology Fellow

Education: B.A. chemistry, F&M College, D.O. and M.S.Ed., University of New England, Biddeford, ME

Training: Pediatric residency and Hematology and Oncology fellowship, Doernbecher Children’s Hospital, OHSU, Portland, OR

Scientific interests: My current project is aimed at investigating macrophage-tumor cell hybrids as a biomarker for diagnosis, treatment response, treatment related tumor evolution in pediatric high grade gliomas. My long-term research interests involve the development of a comprehensive understanding of key mechanisms of tumor evolution and how alterations in the tumor microenvironment contribute to tumor heterogeneity, treatment resistance and disease progression.

Brett Walker, M.D.

Brett Walker, M.D. 
Surgery Resident 

Education: B.S. biomedical sciences, Texas A&M University, M.D., Texas A&M University, Health Science Center

Scientific interests: I am a surgical resident interested in the management of malignancies, specifically colorectal cancer with liver metastasis and pancreatic cancers. I am investigating tumor biology with a focus on biomarkers for earlier cancer detection and to guide treatment strategies. 

Ariana Sattler

Ariana Sattler
Research Assistant 2

Education: B.S., biology, minor in chemistry, Southern Oregon University

Scientific interests: Currently I am interested in the involvement of the novel population of circulating hybrid cells in varying cancer stages and in response to treatment, in addition to cancer specific biomarkers, which can potentially lead to earlier detection and diagnosis. Overall I am interested in stem cell, development and cancer biology, and hope to continue my biomedical studies in a graduate/Ph.D. program!

Yuki Chin

Yuki Chin
Research Assistant

Education: B.S., psychobiology, University of California, Los Angeles

Scientific interests: I am interested in using our understanding of circulating hybrid cell formation and their properties in the development of diagnostic and clinical tools to identify high-risk patients and improve patient quality of life.

Thomas Sutton, M.D.

Thomas Sutton, M.D.
Surgery Resident 

Education: B.S. microbiology and molecular biology, University of Central Florida; M.D., University of South Florida Morsani College of Medicine

Scientific interests: I am a surgical resident interested in the multidisciplinary care of gastrointestinal cancers, including pancreatic and colorectal cancer. I am investigating biomarkers to more accurately monitor how patients are responding to medical and surgical therapies for cancer.  

Sidharth Sengupta

Sidharth Sengupta
Research Assistant 2

Education: B.A. in biochemistry, Case Western Reserve University; B.S. in computer science, Oregon State University

Scientific interests: My work focuses on cellular programs within developmental/adult intestinal stem populations and how their mechanisms for maintaining proliferation and plasticity are hijacked in disorders like cancer. Understanding these molecular systems provides insight into the complexity within robust, differentiated tissue and will improve diagnosis, stratification and treatment of disease.
