Chia-Ching Chen, M.A., M.S., Ed.D., CHES
Associate Professor
Director of Health Education
Dr. Chen’s broader research has focused on accessibility, disparities, and psychosocial determinants associated with individual level outcomes. Her recent publications include an empirical study that assesses children’s needs for healthcare services among the variations of State Children’s Health Insurance Program (SCHIP) in the USA (Health Policy, 2010); a community-based study that investigated the psychosocial determinants of participating in colonoscopy testing and their implication for health education among the elderly (Journal of Cancer Education, 2010); a study that employs GIS spatial analysis to identify area where to establish new grocery stores in counties within New Jersey, USA as a solution to address the structural inequalities that disproportionately promote obesity among the underserved and disadvantaged populations (International Journal of Health and Nutrition, 2010); a community-based study that survey on 15,302 elderly people 65 years and older in seven municipalities in 2006 in Japan that reveals clear-cut evidence of barriers to necessary care (International Journal of Environmental Research in Public Health, 2010); an empirical study that examined the waste tire resources recovery program and environmental health policy in Taiwan (International Journal of Environmental Research in Public Health, 2009); an empirical study that examined how the decision to purchase private health insurance and hospitalization is made based on household income and socio-demographic factors under Japan’s national health insurance (Open Economics Journal, 2009); an empirical study that systematically examined the actual use of outpatient services by children as the theoretical-base of realized access (i.e. use of health services) by controlling for influential factors (Applied Economics, 2008); a study that examined children with special healthcare needs and unmet healthcare needs under the State Children Health Insurance Program (The Journal of Insurance and Risk Management, 2007); a community-based study that examined behavioral choices among elderly formal and informal home and nursing home care (Geneva Papers on Risk & Insurance - Issues & Practice, 2006); and an article documenting the importance of education, counseling services from health care providers, mental health agency services, and detoxification treatments on preventing relapse behaviors for substance users (Advances in Health Economics and Health Services Research, 2005).

Hae-Young Kim, M.S., Dr.P.H.
Associate Professor of Biostatistics
Dr. Hae-Young Kim is an Assistant Professor in the Department of Epidemiology and Community Health at NYMC's School of Health Sciences and Practice. Dr. Kim received M.S. and Dr.P.H. degrees in Biostatistics at the University of North Carolina at Chapel Hill. Prior to joining the New York Medical College, Dr. Kim was a senior research scientist/biostatistician at the New England Research Institutes (Watertown, MA), where she involved in the study design and analysis of clinical trials and observational studies. Dr. Kim's primary research interests include statistical methods in clinical trials, clustered correlated data, survival analysis, longitudinal data analysis, and sample size/power calculations. Dr. Kim has authored/co-authored over 40 articles in public health or clinical trial studies and has published extensively in peer-reviewed journals, including Gastroenterology, Hepatology, Blood, Circulation (Heart Failure), Journal of Urology. She has written several first-author papers for the statistical methods journals such as Biometrics and Statistics in Medicine. Her papers focused on survival analysis, cost-efficient HIV screening methods, and sample size and power calculation methods for longitudinal studies with correlated ordinal outcomes and for interval censored survival outcomes.

Penny Liberatos, M.A., M.Phil., Ph.D.
Assistant Professor and Director, M.P.H. Studies Behavioral Sciences and Health Promotion
Prior to coming to NYMC, Dr. Liberatos worked for several not-for-profit organizations in the fields of education and public health in New York City, including work with the NYC Department of Health. Her research interests are quite varied and can be grouped into five areas. The first is an interest in health behaviors that may lead to poor health outcomes in mothers, children and teens, especially within low-income population groups. In this area she has worked with breastfeeding promotion among pregnant/postpartum mothers, asthma management in children and teen pregnancy prevention in youth. A second area of interest is in health disparities especially among immigrants and those of low socio-economic status. For example, one study focused on assessing health disparities for recent immigrants to the Lower Hudson Valley region of New York State. A related area involves health communication in the patient-provider setting, including issues of health literacy, language interpretation and cultural competency. For example, a recent study used iPad technology to empower individuals with intellectual/developmental disabilities to self-report on their health care experiences. A fourth area concentrates on health provider practice. Of particular interest are issues in identifying barriers to medical adherence, screening teens for risky behaviors and psychosocial health issues, and the impact on provider practice when parents refuse to vaccinate their children. The last area involves the impact of health conditions and procedures on health-related quality of life - specifically the assessment of quality of life among those with liver cancer, urinary incontinence, and cochlear implants. This has also included the psychometric assessment of these instruments.

In addition to the above areas of interest Dr. Liberatos also has expertise in several methodological areas. First of these is questionnaire design and survey research. She has consulted extensively with clinicians and researchers to assist them in developing high quality instruments for collecting self-report data. Program evaluation is another area of skill where she has been responsible for several large-scale program evaluations of comprehensive pediatric, educational reading and prenatal care programs and for conducting several community health assessments for public health departments and non-profit organizations in the Lower Hudson Valley region and New York City.

Dr. Liberatos has a passion for public health and for teaching that she communicates to her students and advisees in the M.P.H. program. She also serves as a mentor for students on research projects, often leading to presentations at national meetings.

David Moskowitz, Ph.D.
Adjunct Professor of Epidemiology and Community Health
Dr. David Moskowitz, adjunct professor of Epidemiology and Community Health, received his Ph.D. (2007), M.A. (2005), and B.S. (2003) from Northwestern University. After the successful defense of his dissertation on HIV restitution, he trained as an NIH postdoctoral fellow at the Center for AIDS Intervention Research at the Medical College of Wisconsin. For two years, he developed skills as a quantitative and qualitative HIV/AIDS behavioral scholar. He taught health communication at the University of Texas before becoming faculty at the New York Medical College.

In terms of research, Dr. Moskowitz has over 20 peer-reviewed, scientific articles in academic journals such as AIDS and Behavior, Sexual and Relationship Therapy, Journal of Sexual Medicine, and Patient Education and Counseling. He also is on the editorial board of the Archives of Sexual Behavior. Much of his research centers on risk-taking behaviors among men who have sex with men (MSM), gay and bisexual male health, and patient-provider health disparities within the LGBT community. He additionally is interested in the role of social identity and subgroup affiliation in predicting differences in sexual health. He specializes in correlates of active condom eschewal and continues to contribute to the literature concerning HIV disclosure and other forms of communication regarding HIV serostatus, condom use, and STD/HIV infection. His future research veins include obesity and sexual health, body image and body interpretation, agenda setting and health decision-making, and sexual control.

Dr. Moskowitz holds elected positions in academic organizations. He is the secretary-treasurer of the International Academy of Sex Research (IASR; http://www.iasr.org), which is arguably the top sex research membership organization for the past 40 years. He also is actively affiliated with the American Public Health Association (APHA) and is the membership chair of the LGBT Caucus of Public Health Workers (http://www.aphalgbt.org).

Dr. Moskowitz is an active supporter of the Sex-Positive movement and continues to support education, research, and counseling that advocate sexual expressiveness (regardless of HIV serostatus) as healthy, natural and good.
