Hello! I'm Sam
In addition to my research activity, I enjoy supervising students in biomedical research topics and teaching mathematics. I am active in numerous associations, and currently serve as a board member for the Society of Mathematical Biology and a Science Policy Fellow for the Society of Industrial and Applied Mathematics. In my spare time, I compete in equestrian competitions and am on the board of directors for New Life Center for Thoroughbreds.

EXPERIENCE
Sept. 2019-Present
Research & Development Associate Staff Member
Oak Ridge National Laboratory
Scientist in the Computing and Computational Sciences directorate working in the Advanced Computing for Health Sciences Section. The group uses artificial intelligence and supercomputing to solve the nation’s leading health initiatives.
I am actively recruiting undergraduates and early graduate students to participate in summer internships using artificial intelligence and machine learning for biomedical projects.
July 2017-August 2019
Postdoctoral Research Scholar
North Carolina State College of Veterinary Medicine
Based in Cristina Lanzas’s lab in the Population Health and Pathobiology Department. I developed mathematical models of molecular mechanisms in C. difficile infection and of antibiotic resistance using nonlinear mixed effect models.
2014-2017
Visiting Graduate Student
Biocomplexity Institute of Virginia Tech
I collaborated with bench-top scientist in the Nutritional Immunology and Molecular Medicine Laboratory (NIMML) to understand the effects in an HIV and HPV coinfection. I also participated in laboratory work to gain experience in experimental protocols.
