About my team

I joined the Burnett School of Biomedical Sciences, College of Medicine, University of Central Florida (UCF) in August of 2016. Since then my Biostatistics team has worked on independent and collaborative research projects related to public health. Such projects include smoking cessation, racial and ethnic disparities in health and healthcare, and biopharmaceutical statistics. My team participates in statistical methodological work, performs simulations and computing—including analyses of big data—and collaborates with psychologists, sociologists, epidemiologists, biologists and other sciences within UCF, as well as with outside institutions. My team has diverse backgrounds and research interests!

My personal research areas include statistical applications to biopharmaceutical sciences with a focus on multiple-testing and estimating methods in dose-response studies. I also design and analyze behavioral medicine studies, and survey sampling techniques. In particular, I work on developing statistical methods that can handle partially ordered multiple end-points and can control the overall error rate. These methods are commonly used in drug development for testing the efficacy of a single drug, and the efficacy and superiority of a combination drug. In addition, my research incorporates statistical methods for analyses of national surveys with complex designs. I have completed multiple projects for computing nationwide estimates for smoking prevalence and smoking-related behaviors and assessing the quality of national data via reliability studies. My current research is targeted on assessing racial and ethnic disparities in smoking and quitting behaviors, as well as healthcare for smoking cessation. I completed two half-marathons, one in 2012 (2 hours 8 minutes) and one in 2016 (2 hours and 5 minutes). Now I enjoy bike rides and visit new places with my family. These pictures are taken in Atlanta, GA. My CV.



Dr. Trung Ha (Statistician)

Dr. Trung Ha (Postdoctoral Research Associate) joined the team in April 2017. He received his PhD in Statistics from the University of Florida in 2016 under the supervision of Dr. James Hobert. Trung’s dissertation was titled “Convergence Analysis of Birth-Death Markov Chains and Gibbs Samplers”. Prior to coming to the US, he worked as a researcher at the Hanoi Institute of Mathematics in Vietnam and as a teaching assistant at the Vietnam National University, Hanoi, Vietnam. Trung has also received a Vietnam Education Foundation Fellowship. Trung has an outstanding knowledge of statistics, as well as exceptional computing skills in SAS®, R, Visual Basic, and C++. Currently, he is working on a number of interesting projects related to survey methodology and the social sciences. In one such project, Trung is leading research to explore the longitudinal differences in rates of smoke-free homes in the US. Trung has also recently joined three sections of the American Statistical Association: Survey Research Methods Section, Social Statistics Section, and Bayesian Statistical Science Section. His hobbies include travel and photography.


Dr. Yujiao Mai

Dr. Yujiao Mai (Postdoctoral Research Associate) joined the team in July 2017. She worked as a postdoctoral research associate at the University of Notre Dame from August 2014 to June 2017. Dr. Mai received her PhD in Quantitative Psychology, MS in Developmental and Educational Psychology and BS in Computer Science and Technology from the South China Normal University. Yujiao’s research interests include addictive behaviors. Dr. Mai has exceptional expertise in software development, psychology and statistics. Her family lives in China. She likes Chinese music performed on the Chinese zither or bamboo flute. She also enjoys hiking, playing basketball, and soccer. Mai’s_CV.



Dr. Thanh Pham

Dr. Thanh Pham (Postdoctoral Research Associate), joined team in Sep 2017 as a statistician in Biostatistics team at the Burnett School of Biomedical Sciences, College of Medicine, University of Central Florida. He earned his PhD in Educational Statistics, Evaluation and Research at the University of South Florida in December of 2017. Dr. Pham also has a M.A degree in Applied Economics from Ohio University. He has expertise in applied statistics, educational measurement, and economics. The specific areas include complex multilevel and multivariate models using SAS, Mplus, SPSS, and R. He has several publications in statistical software, educational and applied statistics journals. He also presented his work in various national and regional conferences including Joint Statistical Meeting, American Educational Research Association, National Council on Measurement in Education, and South East SAS Users Group.


Selena Leonardo

Selena Leonardo is an undergraduate student at UCF. She is working toward getting her BS degree in Biomedical Sciences. Selena joined the team as a volunteer student in September 2016; but because of her keen interest in smoking cessation and racial/ethnic health disparities, she became a full student worker in April 2017. Selena actively participates in the team’s research activities. She helps prepare software codes in SAS®, performs statistical analyses, and prepares reports. She has already made a poster presentation at UCF (see the News section) and plans to make several more presentations in 2017-2018. Before joining the team, Selena worked in the Emergency Department of Florida Memorial Hospital Medical Center, where she assisted nurses, helped transport patients, and attended to patients’ other needs. She has also volunteered at the Halifax Medical Center, where she worked at the information desk. Currently, Selena is a member of the American Statistical Association and UCF’s Neuroscience Alliance. Her career goal is to become a pediatric surgeon. She enjoys spending her free time with her family, fishing and snowboarding.


Richard Pack, B.S.

Richard Pack is a recent graduate of UCF’s BS in Biomedical Sciences  with a minor in Psychology. Richard joined in October 2017 following his interests in investigating racial and economic disparities in healthcare and in toxic habits. Richard participates in the team’s research by helping to prepare reports and develop software codes in SAS®. Before joining the  team, Richard previously worked as a resident advisor at a transitional home and later as a medical scribe. At this time he is looking forward to applying to medical school. Richard devotes much time to volunteering- both at Nemours Children’s Hospital and at his church where his wife coordinates children’s and women’s ministries. His hobbies include indulging in frequent hikes with his dog and tending to his garden.


Victoria Owens

Victoria Owens is an undergraduate student studying statistics at UCF. There, she is a member of LEARN, an undergraduate research program for STEM majors. Learning about research led her to join the team in October 2017, where she now helps prepare literature reviews, reports, and papers, perform analyses, and write SAS codes. She enjoys teaching as much as learning and has worked in the past as a math tutor and a martial arts instructor.  In the coming years, she aspires to become a statistician after earning her master’s degree. Her spare time is spread between origami, playing guitar, and strategy games.


Julie Arias, B.A.

Julie Arias graduated from UCF in 2008 with a B.A. in Spanish and a minor in Latin American studies. In 2017, she went back to school to pursue a career in statistics and public health. She joined the team in January 2018, and will be participating in the Crohn’s disease research initiative. Other responsibilities include performing analysis of behavioral and biomedical data, preparing literature review sections for reports and presentations, writing scientific reports and making presentations. Currently, she is taking courses at UCF and working on completing her prerequisites to apply to graduate school for the fall of 2019. In her spare time, she enjoys playing the violin, touring the local theme parks and beaches, and spending time with her friends and family.


We are also thankful to our prior team members who contributed to the team’s progress:
