Research Interests
As an active researcher and investigator for the last 21 years, my focus is always on translational clinical research and projects. From a single case report of discovering an association between a virus and a disease to observational large number of patients studied for many years to evaluate efficacy and safety of treatment or therapy modality. My research categories are: Single Case Reports/rare and unique case presentation (e.g. hMPV and Pertussis-Like Syndrome); Multiple Case Studies/Descriptive Research (e.g. Silver Russell Syndrome); Retrospective/Chart Review/Quantitative Research (e.g. Diabetic Ketoacidosis); and Prospective/Randomized Control Trials (e.g. Heliox Therapy). Other research studies include Community focus/health promotion (e.g. PLAY Program); Medical innovation (e.g. Lumbar Puncture Assist Tool); and Educational studies (e.g. Pre-Clinical Experience).
My main role in any project is being a mentor to the medical students. Every project starts with an idea; a thesis to be examined and investigated. The assigned students will research the thesis and perform the literature review. When the thesis is deemed valuable and applicable, then a purpose of the research will be defined with the main aim to answer the main research question. I put together the main frame for the study design and the students initiate the study starting with the Institutional Review Board (IRB) application when required. Once approved, the study will be launched starting with data collection performed by the students. Once completed, a biostatistician will input the data and produce the results. A team meeting, including myself, the students and the biostatistician, will be convened to review the results and analyze its reproducibility. Once valid, the study abstract and poster will be generated and presented by the students at the college annual research meeting as well at a national conference, such as ACOP and AOA/OMED. Feedback from the experts will be summarized and the final study manuscript will be prepared for submission to a scientific journal for final publication.
Research is rewarding, but it requires patience, dedication, and time allocation. As an example, in one calendar year I conducted 15 pediatric clinical research projects involving more than 20 SWAGÊÓƵmedical students. The average amount of time I invested at the different steps of those projects was 15 hours per week. I have completed 100 research projects since the 2012 opening of the SWAGÊÓƵCarolinas campus, and I am currently mentoring 34 SWAGÊÓƵstudents across 19 active research projects.
