Intramural Research Fellows

Dental Public Health Research Fellowship

Rund Al-Rusan, B.D.S., M.S.C., M.P.H. (2024–2027)

I earned my B.D.S. and Master of Science in Clinical Dentistry in Pediatric Dentistry from Jordan University of Science and Technology. I completed my M.P.H. degree at the Johns Hopkins Bloomberg School of Public Health. Before joining NIDCR as a dental public health fellow, I worked as an instructor in undergraduate pediatric dentistry clinics at Jordan University of Science and Technology, where I taught and supervised students performing preventive and operative procedures aimed at enhancing children’s oral health. My research interests focus on improving children’s oral health, especially in underserved populations. I’m eager to learn and acquire the knowledge and experience in research and interdisciplinary teamwork to make a meaningful impact on oral health.

Ridhima Luthra, B.D.S., M.S.P.H. (2024–2027)

I earned my bachelor’s degree in dental surgery from the Government Dental College in India. After graduation, I practiced clinical dentistry for five years in India and participated in clinical research projects focused on barriers to accessing oral health care for lower-income groups. To further strengthen my research skills, I completed my M.S.P.H. at the Johns Hopkins Bloomberg School of Public Health. During this time, I also interned at the Maryland Department of Health's Office of Oral Health, where I was involved in various oral health programs and research projects aimed at improving oral health across the state of Maryland. My research interests include studying maternal oral health and its effects on pregnancy complications and infant oral health, as well as exploring oral health disparities. Through this fellowship, I aim to refine my skills, gain expertise in dental public health, and advance my career as an oral health care researcher.

Payal Rajender Kumar, M.P.H, B.D.S, M.D.S. (2023–2024)

I earned my B.D.S. and general practice residency from the Government Dental Hospital, India and M.D.S. (master’s in dental surgery, Prosthodontics) from the Sharda University, India. After this I earned my M.P.H. from the Johns Hopkins Bloomberg School of Public Health, Baltimore. I have worked on various large scale public health programs, particularly in low and middle-income countries, with global public health experts at Johns Hopkins.
I joined the Dental Public Health Program looking to harness the potential of recent developments in machine learning and Al to develop advanced solutions for improving oral and dental health.

Iriana Pena Manrique, D.D.S, M.S. (2023–2026)

I earned my D.D.S. from San Antonio Abad Public University in Cusco, Peru. Subsequently, I pursued a certificate in Advanced Education in General Dentistry at the University of Connecticut, an M.S. in Global Health Policy and Management at Brandeis University, and an M.S. in Epidemiology at Georgetown University. Before coming to the United States, I worked in private practice, the public sector, and for organizations aimed at providing dental healthcare to lower-income communities in Peru. My research interests are focused on the prevention of oral cancer and disparities in HPV vaccine accessibility and utilization. I am enthusiastic to continue my training and experience at NIDCR to become a dental public health specialist and promote policies to improve oral health in the population.

Fatemeh M. Pour, D.D.S, M.P.H. (2023–2026)

I earned my D.D.S. from Mashhad University of Medical Sciences, Iran, and my M.P.H. from the University of Texas Science Center at Houston. Prior joining NIDCR as a DPH fellow, I worked as a data specialist at the Diabetes and Glandular Disease Clinic in San Antonio, TX which helped me to gain firsthand experience in a clinical trial research setting. My work experience as a general dentist in Iran included providing dental care to a variety of patients with a focus on children from marginalized populations. I hope to earn an immense set of skills and expertise to be able to impact oral health promotion through research, policy, and interdisciplinary collaborations.

Ishita Singh, B.D.S., M.P.H. (2022–2025)

I earned my B.D.S. from the National Dental College and Hospital, India, and my M.P.H. from the University of Utah. Prior to joining NIDCR as a dental public health fellow, I worked as a healthcare delivery research intern at Intermountain Healthcare to study and address social health determinants’ impact on the population. My research interest lies in oral health disparities, oropharyngeal cancers, and oral consequences of narcotics and combustible product use. I'm keen to advance my career at NIDCR to become a dental public health specialist and researcher to promote oral health sciences and public health practice.

Leah Leinbach, D.M.D., M.P.H. (2022–2025)

I earned my D.M.D. from the University of Pennsylvania and my M.P.H. from Johns Hopkins University. Before joining NIDCR’s Dental Public Health Research Fellowship program, I was an assistant professor and chief of the division of oral health at Pennsylvania State University, delivering patient care in support of cardiac and oncology services. My clinical experience focused on patient oral health care in conjunction with managing other health conditions. I hope to leverage my past clinical experiences with research skills gained through the fellowship to promote the integration of oral health into the broader healthcare system.

Sang-A Park Memorial Intramural Postdoctoral Fellowship

Surangi Perera – Postdoc Fellow (2019–Present)

I was awarded the Sang-A Park Fellowship to support my postdoctoral research. This award has allowed me to focus on my research interests and study neural crest development and differentiation. One of the main projects I have been working on at NIDCR has been to characterize the in vitro generation of human neural crest cells. I am using transcriptomics combined with immunohistochemistry and fluorescent in situ hybridization to increase our understanding of human neural crest development and how these in vitro human models compare to what we know from other animal model systems in vivo. Outside of scientific research, I am passionate about science education and outreach (a key component of the fellowship), and I organize an outreach project at an elementary school in the local area. Together with five other NIH trainees, we design and present hands-on science activities to 4th graders in line with their science curriculum. We hope this will expose the students to what it is like to be a scientist from an early age. The support from this fellowship has allowed me to conduct cutting-edge research, engage in real-world discussions about the place of science in everyday life, and foster the next generation of scientists.

Fellowship Alum

Jamil Cherry – NIDCR Director's Postbac Fellow (2018–2019)

I am a fourth year dental student at Howard University College of Dentistry. In 2019, I completed the post baccalaureate program under the supervision and mentorship of Dr. Marian Young and Dr. Hai Pham. My project involved finding the phenotype of Collagen Type VI knockout mice and its effects on the periodontal ligament. In my free time, I enjoy running, hiking, fishing, and reading science books. I am currently applying to post-doctoral residencies in advanced education in general dentistry and dental public health.
