Sagan Friant -  Principal Investigator


I am a biocultural anthropologist working at the intersection of biological anthropology and human ecology. I integrate theory and methods from anthropology, ecology and epidemiology to investigate health consequences for humans and wildlife living in shared and rapidly changing environments. My work is centered in Nigeria, but has applications to coupled human and wildlife health systems globally.

Graduate students


I am a PhD student on the Immunology and Infectious disease track in the Molecular, Cellular, and Integrative Biosciences program (MCIBS). My research uses metagenomics and immunological tools to understand emerging infectious disease risks associated with handling bushmeat in Nigeria. Prior to joining the RISK lab, I received my MS in Biotechnology at Texas Tech University Health Sciences Center and BS in Biology from Angelo State University. I have conducted research on co-infection and viral transmission dynamics (Hudson/Vandegrift group at Penn State), bat field population studies at Big Bend NP and Central America, and cancer immunotherapeutic research. Upon completion of both degrees, I also worked as a government contractor for the U.S. Navy Medical Research Unit-SA (NAMRU-SA) at JBSA-Fort Sam Houston, where I worked on a DoD-funded project studying snake venom. In 2018 I accepted a J. Lloyd Huck Graduate Fellowship at Penn State University to pursue infectious disease research for the long term. In my free time, I enjoy spending time with my wife and children, playing basketball, exploring the great outdoors (kayaking, disc golfing, longboarding, bioblitzing), and attending Penn State sporting events.

I am a PhD student in the Ecology Program and a J. Lloyd Huck Graduate Fellow. Broadly, my interests lie at the intersection of anthropogenic land use and zoonotic disease emergence. Prior to joining the RISK Lab, I received my MPH in Epidemiology of Microbial Diseases from the Yale School of Public Health, where I conducted research on re-emerging arboviruses and COVID-19. I received my BS from Cornell University in 2016 in environmental science and applied population biology. Previous research areas include Hawaiian forest conservation, Chronic Wasting Disease in Illinois white tailed deer, and population management at the Lincoln Park Zoo in Chicago. In my spare time, I enjoy all things that grow, and tend to a large collection of potted plants. I am also a seasonal ski instructor, music enthusiast, and mother to two annoying felines.

Undergraduate students


Emma Petrick






Major: Anthropology & Spanish

Schreyer Scholar

Paterno Fellow

My research activities with the RISK Lab center on understanding the role of wild meat in human nutrition in Nigeria.  I am currently working on constructing a food composition database using data collected from the field and through review of the literature.  I will use this database to evaluate the nutritional composition of local recipes and diets of forest dwelling populations in Nigeria. 

Grace Lemke 

Major: Biology

Minor: Anthropology and Spanish

Schreyer Scholar


I am a senior undergraduate student pursuing a B.S. in Biology with minors in Anthropology and Spanish. I am currently working on my honors thesis within the RISK lab on traditional medicine, and specifically zootherapy, in West Africa. I am pursuing a career in healthcare, and I'm passionate about holistic healthcare, LGBTQ+ inclusive care, and health education. Additionally, I work two jobs at the Penn State Libraries, I'm the president of Schreyer for Women and a student leader on the Career Development Medical Team, and I volunteer at AIDS Resource Centre County. In my free time, I enjoy hiking, climbing, cooking, and traveling.

RISK Lab Alumni

Métrey Tiv

Postdoctoral scholar


I am a physician specialized in Public Health and Social Medicine. I have conducted interdisciplinary research in Benin, Ivory Coast, Mali, Thailand and France. My research has focused on illnesses impacting populations worldwide (including HIV, TB, HCV, HPV, malnutrition) and on health policies aiming at reducing health inequalities. My research at the RISK lab investigated how concepts of illness, perceived risks and health seeking behaviors inform our understanding of and ability to control Lassa Fever in Nigeria.
