Yumeng Xu

Yumeng Xu has received her Bachelor’s degree (in the areas of Brain & Cognitive Science and Economics) from the University of Rochester in May 2013. Although these two majors may not appear to be connected, for her, she finds that both of these degrees offer different perspectives on human behavior, an element which has great potential in health science information system design. With her personal insight into the decision making processes, which she has gathered through an economic perspective for making the greatest use of available resources and the neurological mechanisms of human brain, she believes that she can help healthcare practitioners to make difficult decisions within complex biomedical situations. During her college life, she has been actively involved with a number of research projects focused on the human decision making processes, and she has subsequently explored the area of Neuroeconomics in the Brain and Cognitive Science department at the University of Rochester. With a M.S in Health Science Informatics degree from the John Hopkins School of Medicine, she wishes to use her knowledge in both brain science and economics to explore predominate examples of intuitive human/computer cooperation, which will allow her to help healthcare practitioners to make the most use of their individual expertise. She also believes that she will be enabled to uncover a variety of essential answers from the big data sets available through social media, so that she may provide people with a better potential in public health. With her combined background in economics and her experience in quantitative training, she hopes that she would be able to bridge the gap between both the information professions and today’s business reality, thereby offering the means for us to provide a pathway between research results and the economic marketplace.


Brett Cropp

Koko Takatori

Koko received her B.A. in Psychology from Wellesley College in 2007. Captivated by the power of visualization in understanding and communicating complex scientific concepts during her Pre-Med years, she went on to obtain her Certificate in Science Illustration from UC Extension Santa Cruz in 2008, where she was introduced to the concept of patient education. She has worked at biomedical visualization studios in New York and Tokyo as a creator of digital information aids for patients and doctors. She came to realize, however, that such generalized information aids tend to result in passive learning and usually lack means of assisting the patients to take further action. At DHSI, she will apply her background in psychology and visualization to explore the effective integration of Personal Health Records in clinical workflow to help empower patients, and to evaluate its impact on collaborative medicine. She would also like to explore ways to offer the technology to mental health populations and chronically ill patients who also manifest associated psychological pathologies.

Koko will be joining DHSI as a Fulbright Grantee from Japan, pursuing M.Sc. in Health Sciences Informatics Research.

Laura Vail

Joe Warren

Joe Warren Portrait

My background is completely healthcare. I started at the lowest level cleaning utility rooms and taking bodies to the morgue. And somehow ended up in the arena of systems and information technology, where I installed and managed applications. I have worked for healthcare providers, software & hardware vendors, and consulting firms focused on defining systems needs and implementing information solutions in healthcare environments. These solutions ranged from the general accounting areas to hospital information systems to ancillary systems such PACs, pharmacy, and laboratory. I have seen systems evolve from just feeding the billing system to today’s valuable decision support systems and evolving medical records for clinicians.

My work in the healthcare field has also given me the great opportunity to work in the U.S., Europe, Middle East, Africa, and Latin America, where I have had the chance to learn about numerous healthcare systems and see many providers at work in various environments.

Recently, I have had the opportunity to see the policy side of the U.S. healthcare system by first working in a non-governmental organization focused on prevention through evidence-based medicine and now working at the Centers for Disease Control and Prevention (CDC) as the Special Assistant to the Deputy Director in the Center for Global Health, who is teaming with USAID and the State Department on the Global Health Initiative ( I believe these recent experiences have broadened my perspective on the impact of government programs to improve the health of all populations, but now it is time for me to return to my roots - the informatics side of health systems – and to get the formal education that the Applied Health Sciences Informatics program offers. Hopefully, the program will give me the knowledge, both technical and managerial, to step into my next successful career move. A step into some position which will allow me to develop innovative ways for practical application of sharing information -- with the ultimate goal of improving direct care, managing diseases, and helping increase the focus on prevention.

Shuangchao Ma

We use statistical methods to correlate genotype with TSPO – radiotracer binding affinity. Our hypothesis is that gene mutation causes varies TSPO protein formation, and as a result there is bias associates with the radiotracer binding affinity measurement. Our goal is to exclude these biases.

In detail, genomic DNA was obtained from peripheral leukocytes,using high salt extraction methods. The polymorphism rs6971 was genotyped variously using a TaqMan assay on demand C_2512465_20. The allele T147 was linked to Vic and the allele A147 was inked to FAM. Polymerase chain reaction reactions were performed in a 96-well microtiter-plate on a GeneAmp PCR System 9700 (Applied Biosystems). After PCR amplification, end point plate read and allele calling was performed using an ABI 7900 HT (Applied Biosystems) and the corresponding SDS software (v2.2.2, Applied Biosystems). Radiotracer binding affinity measurement is carried out in the Brain Sciences Institute at Johns Hopkins.
