Helia hadavi

Background: I received my Bachelor of Science degree in Biological Sciences from University of Maryland College Park in 2013 and my Master of Science degree in Biotechnology with a concentration in Molecular Targets and Drug Discovery Techniques from Johns Hopkins University in 2017. During my undergraduate studies, I worked as a summer intern with the National Institute of Child Health and Human Development to research the biological characteristics, properties, and roles that Human Epidermal Growth Factor Receptor Type 2 (HER2) over expression have in ovarian and breast cancer. After graduating with my master’s degree, I worked as a post baccalaureated fellow with the National Cancer Institute to help conduct two research projects: one focused on the signaling pathways of alpha synuclein involved in Parkinson’s development and the other focused on enhancement and testing of an immunotherapeutic treatment regimen in mice for treating melanoma.
Research Interests: The areas I would like to conduct research focus on infectious disease epidemiology, the roles lack of physical activity and obesity have in the risk of developing eating disorders, suicide prevention and interventions, mental health of LGBTQ+, collegiate, and military individuals, occupational risk factors of mental illness, and the role of health disparities in physical and psychological health.
Why You Chose UNC Charlotte: I chose UNC Charlotte because the Epidemiology faculty perform research on topics and issues that I find fascinating and valuable. In my opinion, this program will enable me to become proficient and expert in the foundational knowledge, skills, and tools for conducting research in any sector where epidemiology plays a critical role.
Md. Mashfiq Hossain Khadem

Background: I am an international Ph.D. student in the Epidemiology program from Bangladesh. I
completed my undergraduate degree in Doctor of Veterinary Medicine (DVM) from
Sylhet Agricultural University in 2021, followed by a Master of Science in Epidemiology
and Public Health from the same institution in 2023. I believe the COVID-19 pandemic
greatly influenced my decision to focus more on research rather than clinical practice.
During my master’s, I was involved in several projects as a research assistant, studying
the epidemiology of infectious diseases, particularly zoonotic ones. I was fortunate to
gain experience in field surveys, as well as wet and dry lab activities during this time.
My thesis focused on estimating the true prevalence and determinants of Bovine
Brucellosis using Bayesian analysis. Additionally, I was involved in studying diseases
like Babesiosis, Anthrax, and Foot-and-Mouth Disease in livestock populations,
especially in the northeastern part of Bangladesh. I am a big fan of cricket, love riding
bikes and enjoy watching movies.
Research Interests: My research interests center on infectious disease epidemiology and biomedical data
sciences. I am eager to develop my skills in machine learning, spatio-temporal analysis,
risk assessment, and modeling within the realm of infectious diseases.
Why I Chose UNC Charlotte: The multidisciplinary approach of the faculty in the Department of Epidemiology and
Community Health, particularly their efforts in combating infectious diseases through the
Computational Intelligence to Predict Health and Environmental Risks (CIPHER)
research center, drew me to UNC Charlotte.
Saeed Saadat

I earned a Bachelor’s degree in Statistics and a Master’s degree in Biostatistics from Iran. After completing my degrees, I worked for three years as a biostatistician at two medical universities and health research centers. Additionally, I earned an MPH with a concentration in healthy aging. Driven by my interest in machine learning modeling, I furthered my education in Germany by completing courses in data science. My research focuses on the application of machine learning algorithms and predictive models, particularly in the field of chronic disease epidemiology in older adults, with a special emphasis on cognitive impairment and Alzheimer’s disease. When choosing a PhD program, UNC Charlotte stood out to me for its robust curriculum in epidemiology and the diverse research interests of its faculty members. The accessibility and responsiveness of the faculty reinforced my decision that this was the ideal place to pursue my studies.

Farzana RAHMAN

I hold dual degrees—an MD (Doctor of Medicine) and an MPH (Master of Public Health). My MD degree provides a strong foundation in clinical medicine, enabling a comprehensive understanding and management of patient health. In addition to this, my MPH degree equips
me with expertise in public health principles, and practices, focusing on population health. The combination of these degrees empowers me to integrate clinical insights with public health strategies, contributing to well-rounded healthcare solutions. As a public health enthusiast, I have worked on several research projects to identify the roots of the prevalent issues of society by working at the ground level. During the COVID pandemic, I worked with healthcare professionals, to measure sleep patterns associated with their job stressors, among those serving severely ill patients fighting for their lives. To continue the surge, I extended my work on evidence synthesis projects to assess the symptoms of long COVID-19 haulers. I also contributed to some projects on early childhood development, intimate partner violence, and some mental health issues. Apart from this, I was serving as a faculty in the Armed Forces Medical College, Dhaka. However, being a citizen of Dhaka, the third most polluted city in the world, the grievous health impacts of environmental pollution were not surprising to me, but undoubtedly, the number of annual deaths pertaining to environmental pollution triggered my conscience
miserably. Therefore, I developed an immense urge to work on environmental issues to ensure a better life expectancy for the people of my country. UNC Charlotte has piqued my interest because of its multi-disciplinary and research-oriented approach. The Ph.D. program at UNC Charlotte has a flexible curriculum to attract a diverse range of faculty members and students from different institutions and disciplines, which brings fresh perspectives and expertise to the program. Therefore, I believe, this program will equip me with enhanced knowledge to facilitate my learning experience and arm me with the skill sets to address specific health issues more elaborately. My goal of establishing health equity and my values also align perfectly with UNC Charlotte’s mission statement. I could not think of a
better place than the Department of Epidemiology at UNC Charlotte, for taking my first steps to fulfill my dreams and it is an absolute honor to be a part of UNC Charlotte.
