Program Manager
Jasmine Carcamo
Jasmine is the Project Manager at the Institute for Genomics in Health and the POP-GEM Lab at the State University of New York Downstate Medical Center. Jasmine attended Stony Brook University (SBU) where she received her master's in psychology with a focus in Clinical Psychology. She joins the lab with 7 years of multidisciplinary clinical research experience. Jasmine previously oversaw an NIA funded, international, multi-site study examining healthy aging phenotypes at Columbia University Irving Medical Center's (CUIMC) Taub Institute for Research on Alzheimer's Disease and the Aging Brain. Jasmine has also participated in various NIH funded research studies regarding predictors of Alzheimer's Disease in community-based cohorts at CUIMC and the identification of Post-Traumatic Stress Disorder using polygenic risk scores in the World Trade Center Responder population cohort at SBU. At the POP-GEM Lab, Jasmine will contribute to the operational infrastructure of the lab in addition to her collaboration on various projects such as the Latin American Genomics Consortium.
Research Associate/Master's Student
Cierra Machado
Cierra graduated from the University of Minnesota - Rochester with a Bachelor's degree in Health Sciences. She is currently a student at the State University of New York Downstate Health Sciences University pursuing her master's in public health. Cierra will be assisting with various ongoing projects in the POP-GEM lab to gain research experience before hopefully continuing her education in medical school.
Research Associate/Medical Student
Asma Sadia
Asma is a first-year medical student at the State University of New York Downstate Medical Center. Her long-term goals involve bettering our delivery of mental healthcare especially in underserved communities, and she aims to assist the lab through data management involving diverse study populations and help translate research findings and build awareness surrounding the genetic and environmental variables contributing to mental health outcomes.
Research Associate/Medical Student
Huzafia Dorria
Huzaifa is a first-year medical student at the State University of New York Downstate Medical Center. His goal is to gain research experience by assisting with various ongoing projects in the POP-GEM lab. In the future, Huzaifa hopes to apply the knowledge he gains to explore the impact of stigma on mental health outcomes across minority populations.
Research Associate/Medical Student
Kaila Boyer
Kaila is a second-year medical student at the State University of New York Downstate Medical Center. She received her master's in public health from Columbia University Mailman School of Public Health, where she did research in environmental health and molecular epidemiology. Kaila will be assisting with various POP-GEM projects, and hopes to learn more about the genetic, environmental, and social factors that influence psychiatric conditions.
MD/Ph.D Student
Evan Davis
Evan graduated from Stony Brook University with a BS in Biochemistry and Physics. He is a current MD/PhD student at SUNY Downstate with an interest in ophthalmology and computational research. His project in the POP-GEM lab focuses on the differential genetic signatures of schizophrenia across diverse populations. He plans to use the analytical skills he learned in the POP-GEM lab to discover genetic relationships of eye diseases like glaucoma across ancestral backgrounds and develop a model for how genetics and comorbid systemic inflammation affects disease development and progression.
Omics Research Scientist, Prinicpal Investigator at RTI International
B. Todd Webb, PhD
Dr. Webb is trained in quantitative human genetics with an emphasis on complex genetics and bioinformatics and has a background in molecular biology and genomics. He has performed statistical and bioinformatic analyses using data from multiple high-throughput ‘omic’ platforms including whole-genome sequencing, genome-wide association, copy number variation, expression, metabolomic, and proteomic studies across multiple species. Dr. Webb has several collaborative projects with the POP-GEM Lab including Chair of the Bioinformatics core.
Assistant Professor
Amanda Gentry, PhD
Dr. Gentry's PhD training was in biostatistics with a concentration in genomics. Dr. Gentry develops novel and innovative statistical methods for applicable to both continuous and categorical phenotypes with molecular genetic data of many types, including whole-genome sequencing data.
Assistant Professor
Dana Lapato, PhD
Dr. Lapato is an Assistant Professor of Human and Molecular Genetics at Virginia Commonwealth University with training in molecular, behavioral, and statistical genetics and clinical cytogenetics. Dr. Lapato promotes open science and rigorous research through education and training and is a proud member of the NINDS Rigor Champion community. Dr. Lapato's long-term research goals include developing robust methods for exploring the genetic architecture of psychiatric disorders using cross-disorder, multi-ancestry approaches to understand the interface of psychiatric nosology, genetic variation, and multi-omic interactions.
Quantitative Human Genetics Doctoral Candidate
Madhur Singh
Madhur is a PhD student in Quantitative Human Genetics at VCU School of Medicine and the Virginia Institute for Psychiatric and Behavioral Genetics (VIPBG). With a background in Medicine from India and in Health Policy from Norway, Madhur’s primary research interests are in the applications of Psychiatric and Statistical Genetics in advancing Precision Medicine in Psychiatry. At the POP-GEM lab, he studies cross-population heterogeneity in the genetic architecture of depression and substance use disorders.
5th Year Clinical Psychology Doctoral Candidate
Terrell Hicks
Mr. Hicks is a PhD student in the Clinical Psychology Doctoral Program at the Virginia Institute for Psychiatric and Behavioral Genetics at Virginia Commonwealth University. His long-term research goals are largely focused on the identification of potentially modifiable environmental variables that increase risk for post-trauma psychopathology (& interaction with genetic variants), with the aim of translating these findings into culturally sensitive prevention and secondary intervention programs.
Integrative Life Sciences Doctoral Candidate
Mariam Sankoh
Mariam is a PhD student in the Integrative Life Science Doctoral Program at Virginia Commonwealth University at the Team RIA and POP-GEM Lab.
