Lab Members

CURRENT MEMBERS and AFFILIATES

Riley Johnson is an undergraduate studying public health at the University of Arizona. She is set to graduate in May 2017 with a B.S. in Public Health and a minor in Spanish. Her work with the Brown Lab is supported by the GRADLink fellowship from Bio-5 where she works as part of a team fo faculty, graduate and undergraduate students from public health, math, and geography. She is assisting with gathering data for a project that is tracking chikungunya spread in high-risk countries. She is also assisting with launching a study on vaccine uptake behavior among health care personnel. On the side, she is an intern with The University of Arizona Cancer Center Skin Cancer Institute's community outreach and education branch. Professional interests include epidemiology, health promotion, and reproductive health. 

Erin Pelley is an undergraduate studying Public Health with a minor in Spanish at the University of Arizona. She is currently working through the GRADLink fellowship with faculty, undergraduate and graduate students from geography, mathematics, and public health to map and describe the spread of vector-borne diseases throughout the Caribbean. In addition, she will be using data from CDC WONDER to describe trends in chronic disease with infectious causes. Erin has also been involved with a research workgroup studying the H. pylori infection and gastric cancer. Through this group, Erin identified trends in gastric cancer incidence among various ethnicities using SEER databases; she presented her findings at the Arizona Cancer Center Scientific Retreat, the MEZCOPH Poster Forum, and the First Year Honors Project Poster Presentation. Research interests include epidemiology, health promotion and global health. 

Rachel Treistman is an undergraduate student studying public health at the University of Arizona. She is set to graduate in May 2017 with a B.S. in Public Health. Her project is evaluating temporal trends in vaccine coverage and measles incidence in the US. In addition to her work in the Brown Lab, Rachel interned with Harris County Public Health in the Mosquito Control division. She is currently interning with Tucson Medical Center, in the department of Infection Control. Professional interests include: epidemiology, minority health and environmental health.

PREVIOUS MEMBERS

Shelby Calvillo graduated with a BS in Public Health in 2015. She is starting the MPH program in epidemiology at the University of Arizona in the fall. Her research interest includes vector-borne diseases specifically dealing with mosquitoes. Her undergraduate internship project was mapping postiive Aedes aegypti trapping sites in Pinal County, AZ.

Robert Clark is a graduate of the UofA with a BS in Public Health. He was a UROC fellow in the Brown Lab over the 2013 summer and successfully published his project in the journal of Vectorborne Zoonotic Diseases. Robert's project used Pima  County rabies data to describe the temporal and spatial nature of rabies in Pima County using positive exposure data from 2004 to 2010. He identified hot spots and interpreted these findings in relation to prevention education programs for high-risk areas. He is continuting this project into the fall semester where he will be building a regression model with different predictors examining why certain areas are hot spots. Predictors will include population density, the distance to wash and bridges calculations, USGS land cover (urban versus forest) and elevation all of which have biological relevance and some (distance to wash) have been identified in this analysis as important. This portion of the study will strengthen the  argument to target certain hotspots for rabies education and prevention. He is currently a graduate student at the UofA in Global Health - Maternal Child Health with ultimate goal of continuing research in infectious disease epidemiology among children. 

Victoria Hansen earned her BS in Biochemistry from Arizona State University in 2012 and finished an MS in Epidemiology at the Mel and Enid Zuckerman College of Public Health at the University of Arizona (12/2015). Her interests include infectious disease, specifically zoonotic disease, and preparedness.

Steve Haenchen, MPH, came to the University of Arizona in 2011 seeking a PhD in epidemiology.  Since joining the college of public health he has focused his research on how climate affects vector-borne disease transmission.  

Marvin Langston graduated in 2016 from the UA program and is currently a postdoctoral scholar in the Division of Public Health Sciences at Washington University School of Medicine in St Louis, MO. His research interests focus on infectious, inflammatory, and environmental cancer etiologies.  For his thesis, Marvin evaulated the spatial epidemiology of melanoma and its relation to the environmental carcinogen, arsenic.  He also devised an interesting way to retrospectively assess UV exposure. 

Quyymun Rabby  graduated with a BS in Biology from University of Arizona in 2014 and an MPH in Epidemiology at the Mel and Enid Zuckerman College of Public Health in 2016. She was supported by a HRSA Traineeship to work on a joint project between the Brown Lab, Margaret Wilder (UA Geography), and  Arizona Department of Health Services to develop a vulnerability assessment report on climate change and its impact on vector-borne diseases and valley fever in Arizona. 

Ellen Shelly, M.S., Ellen obtained her BA in Biology from Augustana College in Rock Island, Illinois and her MS in Epidemiology from the Mel and Enid Zuckerman College of Public Health at the University of Arizona with a thesis entitled "Chagas disease in Mexico." Her thesis was published in Public Health Reports in 2015. She is currently working as a Project Evaluator with National Community Health Partners in Tucson.

Sharia Smith is a Medical Anthropology and Peace Studies double major at the University of Notre Dame and was a FRONTERA Border Health Scholar in the Brown Lab over the 2013 summer. She collected mortality rates from 1990-2010 in order to investigate the changing rates of infectious disease mortality in the United States. In addition she looked at 15 infectious diseases of modern importance and looked specifically at differences in infectious disease mortality in counties along the US-Mexico border compared with the rest of the US. She’s returned to Indiana to continue her studies, while working with a human rights anthropologist and conducting research on sport related concussions.
