Aisha S. Dickerson, PhD
Yerby Fellow: 2017 – 2019

Current Title(s): Assistant Professor, Department of Epidemiology, Johns Hopkins Bloomberg School of Public Health

Research Interests: She is an environmental epidemiologist with a research focus on environmental risk factors for neurodevelopmental and neurodegenerative disorders. Her past research has primarily evaluated associations between exposures to air pollution and heavy metals and risk of autism spectrum disorder. Additionally, she continues to investigate the influence of disparities in autism assessment and service provision along with environmental injustice in low-income communities. She holds a BS in Biology and MSPH in Epidemiology from the University of Alabama at Birmingham. After receiving her PhD in Epidemiology from the University of Texas Health Science Center at Houston, Aisha also completed a year of postdoctoral training at the US Environmental Protection Agency.

“Through the Yerby Fellowship Program, I was able to join a unique and elite network of scholars. Not only have I built potentially life-long friendships with fellows in my own cohort, I have been able to connect with past Yerby fellows to discuss best methods for productivity and suggestions for career development. Through Yerby workshops, I was also able to prepare for the academic job-search process and successfully negotiate a competitive start-up package for my newly acquired faculty position.”

Maria Andree Lopez Gomez

María Andrée López Gómez, PhD

Yerby Fellow: 2017 – 2019

Current Title(s): Postdoctoral Fellow, Memorial University, St. John’s Newfoundland, Canada


Current Title(s): Her broad research interests lie on the impact that public and organizational policies have on workers’ health. Her doctoral research focused on how labor market policies and benefits in Spain shape labor trajectories and how these trajectories determine mortality and permanent disability rates. The core of her current research focuses on assessing policies, programs and practices at the workplace and how these impact workers’ health and well-being. She is interested in how policies and practices impact workers’ mental health and injury rates in populations of patient care workers in hospital and nursing home settings. She is also working on intervention development and evaluation and the translation of research into practice by the study of policy implications from important work on workers’ health. Maria Andree received her Bachelor of Arts with a double major in Neuroscience and French from Wellesley College. She holds a PhD in Health and Life Sciences, a Master of Public Health and a Master in Sociology and Demography from Universitat Pompeu Fabra in Barcelona, Spain.

“The Yerby Program has been a great opportunity to advance my skills in academic research and build my capacity towards a path of independence. The Program offered insightful workshop focused on academic skill development and tailored for us. Some of the workshops included academic writing skills, grant writing skills and leadership in academia, among others. As Yerby Fellows, we were provided with many supports to advance our research and with various opportunities to speak one-on-one with experts in many fields who provided feedback on our career plans as well as on our research. I am very thankful for the Yerby Program and the supportive environment it provided me with.”

Tia McGill Rogers

Tia McGill Rogers, PhD, MPH
Yerby Fellow: 2017 – 2019

Current Title(s): United States Public Health Service Commissioned Corps Officer, CDC Epidemic Intelligence Service; Visiting Professor, Department of Epidemiology

Research Interests: As a behavioral scientist, Tia has worked in various capacities in the field of public health, including direct service provision, training, and research—all towards the goal of advancing the knowledge base and service availability for children and families across the globe.  Her research encompasses mixed methods approaches to understanding the life course epidemiology of mental health problems. These include posttraumatic stress disorder, depression, and substance abuse associated with experiences of concentrated adversity such as: community and family violence, child maltreatment, disaster, and war.  Her most recent studies explore the influence of mental health on intervention utilization and behavior change, key factors related to coping with violence exposure among adults exposed to war during childhood, and associations between mental health, violence, and the transition to parenthood.  Currently, under the mentorship of Dr. Karestan Koenen, Tia is working on several projects investigating epigenetic differences associated with early trauma exposure that may help explain associations between adverse childhood experiences and mental and physical health problems across the life course.  Tia received her Bachelor of Arts in Psychology, with a mental health concentration from Spelman College, and holds a Master of Public Health from Emory University’s Rollins School of Public Health. After receiving her PhD in Behavioral Science from Georgia State University, Tia completed a one-year Eunice Kennedy Shriver National Institute of Child Health and Human Development postdoctoral research fellowship in the department of Global Health and Population’s Research Program on Children and Global Adversity at the Harvard T.H. Chan School of Public Health.

Bettina Drake, PhD  
Yerby Fellow: 2006-2009

Current Title(s):    Associate Professor, Division of Public Health Sciences, Department of Surgery, Washington University School of Medicine

Research Interests:    Bettina Drake is a cancer epidemiologist at Washington University School of Medicine and Siteman Cancer Center. Her research interests are in reducing disparities in cancer by focusing on cancer-prevention strategies through nutritional and community-based approaches. Currently, she is conducting community-based research through the Program for the Elimination of Cancer Disparities (PECaD) on minority recruitment into biorepository studies. In addition, she co-leads the Prostate Cancer Community Partnership, a community partnership of PECaD, which seeks to reduce prostate cancer disparities in the region. In addition to cancer prevention through community-based approaches, Dr. Drake has institutional and Department of Defense funds to research the benefits of vitamin D on prostate cancer. She is most interested in how her community-based work informs and strengthens her nutritional epidemiology findings. Information gained from community-based studies informs both study design and recruitment strategies. In turn, the results of the cancer prevention work can be disseminated in collaboration with community partners.

Lupita Montoya, PhD  
Yerby Fellow: 2001-2003

Current Title(s): Assistant Professor,  Department of Civil, Environmental and Architectural Engineering, University of Colorado Boulder

Research Interests: Dr. Montoya’s primary area of research is the study of indoor air quality and the health effects of aerosols (a.k.a. particulate matter). She is especially interested in elucidating the role that biological and physicochemical characteristics of various aerosols play in the development of disease and toxicity. One major thrust of this research is developing new models for the study of disease. In the case of allergenic aerosols, she focuses on the link to allergies and asthma. In this general area, she is also trying to elucidate the connection between the physico-chemical characteristics of various nanoparticles (e.g., TiO2, Al2O3, nanotubes) and possible toxicity and immune effects using in vitro models.
