Mark Shriver – Principal Investigator

Dr. Shriver’s lab addresses questions related to recent human evolution — in particular the evolution that took place during and after the spread of anatomically modern humans across the globe. Since it is clear from both physiological and genetic studies that all human populations have a very recent common origin, features (namely, genes and genetically determined traits and disease risks) that are different between populations are unique in having undergone evolution in the recent past.

 


Laurel Pearson – Researcher and Lecturer

Laurel is a lecturer at Penn State University.  After completing her B.A. in Anthropology from Louisiana State University, she worked as a research assistant in the College of Tropical Agriculture at the University of Hawaii – Manoa and in the Department of Nutrition at the University of Tennessee – Knoxville. Her research focused on the complex interplay of diet to disease, such as metabolic disturbances associated with antiretroviral drug therapies and tumorigenesis associated with cancer. Currently, her research focuses on the genetics of preterm birth among African American women as well as the genetic basis of human dental variation.

Tomas is a doctoral candidate in Anthropology and Bioethics. He is currently working on human facial variation, particularly facial sexual dimorphism, and its genetic underpinnings, using geometric morphometrics and diverse genetic analyses. Also, he works on the ethical issues emerged by the development of gender-specific medicine, as well as the presence of sex differences in health and disease more broadly.

Zeenat is completing her Ph.D. in Forensic Sciences from University of Health Sciences, Lahore, Pakistan. She has completed her bachelors in Forensic Science with a research focus on Forensic Biology and worked on DNA quantification of bloodstains recovered from washed fabrics. Her Ph.D. focuses in Forensic Biology particularly about Advances in Forensic Molecular Biology and Genetics, her current project is about “Predictive Modeling of Nose Shape Variations on the Basis of Known Genetic Associations”. Her main research area is Human DNA Phenotyping; focusing on reconstruction of 2D and 3D faces from genes and voice recordings, and biometrics. Currently, she is a visiting scholar at Penn State completing her Ph.D. research work.

 


Sarita W. Greer – Project Coordinator

 

Sarita W. Greer graduated from Penn State University with a B.S. in Biological Anthropology in 2015. During her undergraduate studies she worked as a research assistant on the ADAPT, ADAPT2 and Mexican Variation projects under Dr. Mark Shriver and Dr. Laurel Pearson. Post graduation she worked in administration of various  biochemistry and molecular biology research labs before returning “home” to Shriver Lab. Sarita coordinates the many ongoing research projects in the lab, manages the undergraduate researchers and over all ensure the smooth progression of lab activities.

 


Soham M. Bhide – Undergraduate Researcher
