  1. Clinical Research Fellow at Stanford University, School of Medicine (July 2019 – September 2021). Studied infectious complications post bone marrow transplantation, focusing on CMV-related outcomes, therapy for HHV-6 in cord blood recipients, and the impact of SARS-CoV-2 in transplant and CAR-T therapy recipients.
  2. Faculty-Supervised Research at UAMS, Division of Infectious Diseases (July 2018 – June 2019). Developed institutional guidelines for appropriate use of procalcitonin testing, implemented a multi-departmental educational protocol, and evaluated its impact on antibiotic use and hospital resource utilization.
  3. NIDDK Medical Student Summer Research Program Intern at UT Medical Branch, Dept. of Neurosciences and Cell Biology (May 2010 – June 2010). Investigated novel putative stem cell markers in intestinal crypts and the effects of progastrin on stem cells in colorectal cancer development.
  4. Faculty-Supervised Research at Rice University, Department of Bioengineering (October 2007 – May 2009). Researched protein expression and leaflet remodeling in mitral valves due to tachycardia-induced cardiomyopathy.
  5. Summer Research Program Intern at M.D. Anderson, Dept. of Experimental Diagnostic Imaging (June 2006 – August 2006). Explored the synthesis of an image-guided therapeutic agent combining rhenium and glucosamine for localized radiation therapy to tumor cells.
  6. Research Assistant at Baylor College of Medicine, Dept. of Biochemistry & Molecular Biology (January 2006 – May 2006). Studied the nuclear envelope fragmentation in mutant cells of fission yeast during mitosis.
