The Environmental Health in Vulnerable Populations Lab focuses on studying exposures to environmental contaminants arising from consumer product use among vulnerable populations understudied and underrepresented in public health research with a focus on women of reproductive age, pregnant women, children, low-income populations, and occupational populations.
Our group also seeks to understand the potential adverse health effects of these exposures to inform and develop culturally-appropriate interventions to reduce exposures and their potential health risks, inform policies, and raise environmental health awareness.

Antimicrobial Agents and Asthma Morbidity Among African American Children with Asthma
Funder: National Institutes of Heart, Blood, and Lung (NHLBI)
K01 Career Development Award
PI: Lesliam Quirós-Alcalá
The aim of this project is to test the central hypothesis that exposure to antimicrobial and endocrine disrupting compounds (EDCs) in personal care products, increases the risk of asthma morbidity among African American children, a vulnerable population experiencing high asthma morbidity and high exposure to select EDCs in personal care products. This project also aims to identify consumer behaviors that may be linked to elevated exposures to chemicals present in consumer products.

Funder: University of Maryland Tier I Seed Grant
PIs: Lesliam Quirós-Alcalá, Mary A. Garza
The goal of this project is to identify modifiable behavioral and environmental risk factors in a cohort of 156 low-income immigrant Latino workers to aid in chronic disease prevention efforts and to reduce environmental health disparities. This is a mixed methods research project and data collection efforts consisted of focus groups, questionnaires and biospecimen collection. While the project period has ended, work is ongoing.
Collaborators: Dr. Mary A. Garza (UMD Department of Behavioral and Community Health), Dr. Robert Feldman (UMD Department of Behavioral and Community Health), Dr. Ruth Zambrana (UMD Department of Women's Studies), Dr. Kathleen Stewart (UMD Geographical Sciences Department), Ivonne Rivera (Rivera Group, Inc.)
North American Partnership for Evironmental Community Action Program Pilot Project for Building Environmental Health Capacity through Child Care Settings
Funder: North American Partnership for Environmental Community Action Program
PI: Nse Witherspoon, Children’s Environmental Health Network
The aim of this project was to raise environmental health awareness and educate childcare providers in the U.S.- Mexico Border on strategies to minimize children’s exposures in child care centers to agents linked to asthma and other adverse health effects. Bilingual training materials were developed as part of this project and Dr. Quiros-Alcala also led a six-hour workshop in Spanish (8/2016, Los Angeles, CA) for childcare providers on environmental health to reduce indoor environmental exposures to children and caregivers in child care centers.

Meleah Boyle, Doctoral Student
I am a doctoral student at the Maryland Institute for Applied Environmental Health. My research interests include understanding how exposure to chemicals in consumer products impact health outcomes, as well as environmental health literacy. In 2010 I earned my B.S. in Community Health and in 2014 I earned my MPH in Environmental Health both from the University of Maryland School of Public Health. I have been a research assistant with Dr. Quirós-Alcalá since beginning the doctoral program and have had the opportunity to work on several projects to address occupational exposures among immigrant Latino workers as well as hair salon workers.

Darya Dokshina, MPH 2018
My career goal is to work on a local level to address social determinants of health, through an environmental health lens. My particular interests lie in exploring exposure to environmental and occupational agents and the associated health outcomes in vulnerable communities. Pursuing a MPH degree at the University of Maryland School of Public Health has presented me with opportunities and faculty mentorship that have sparked an interest in this field and given me relevant skills and experiences. I contributed to the development of study instruments for Dr. Quirós-Alcalá's UMD Tier I Latino study and also collected and processed biospecimens for the study.
Current Position: Research Fellow at the EPA Office of Water, Water Security Division
Kaley Beins, MPH 2018
A Maryland native, I earned my B.S. in Environmental Biology from Georgetown University. During my time as a Fulbright Fellow in Panama, my work at the environmental health nonprofit Center for Health, Environment & Justice (CHEJ), and an internship with the Latino Health Initiative of the Montgomery County Department of Health and Human Services, my academic interests shifted from ecology and environmental biology to the effects of the environment on human health. As an MPH student, working in Dr. Quirós-Alcalá's lab, in addition to taking her course in occupational health, has given me a better perspective on the exposure disparities and health outcomes associated with work environments. These experiences have also informed my Master's thesis work, specifically how occupational exposures could play a role in the environmental etiology of a rare subset of autoimmune disorders.
Current Position: Evironmental Health Outreach Specialist, Alexandria Health Department
Melissa DeSantiago, MPH 2017
I graduated with a Masters in Public Health (MPH) in Environmental Health Sciences from the Maryland Institute for Applied Environmental Health at the University of Maryland College Park in May 2017. As a graduate student, my academic interests greatly developed within children’s environmental health and the occupational health realm. While working under the direction of Dr. Quirós-Alcalá, I had the opportunity to be involved in several research opportunities addressing occupational exposures for Latino workers and fostering awareness of environmental hazards in childcare settings, particularly in low-income Spanish-speaking communities. This led to my collaboration with the Children’s Environmental Health Network, which supported the expansion of the Eco-Healthy Child Care® (EHCC), a training program for Spanish-speaking child care professionals. Following graduation and using both my B.S. degree in Biosystems Engineering and my MPH in Environmental Health, I decided to join United Therapeutics Corporation in Silver Spring, MD as a EHS Engineer, where I am able to use my education and experiences to continue to promote healthy, safe, and sustainable communities for all.
